Dall Island
How is the figure "Canada – United States: 140 m (460 ft)", at the southern tip of Dall Island, obtained? As far as I could search, Point A is the southernmost point of Dall Island, resulting in a Zero meters land border. Can someone add additional details about it? Thank you in advance Luis wiki (talk) 15:30, 16 December 2017 (UTC)
 * I agree that there is no length to a point. More info: The tip of Cape Muzon was established as the "point of commencement" of the international boundary with Alaska in the Anglo-Russian Convention of 1825. A Court of Arbitration in 1903 ruled that Point "A" (54.66222°N, -132.68419°W) was the initial point of this boundary. Canada has accepted this as a demarcated boundary; however, the U.S. disputes that Point "A" is a boundary point.

Unnamed rock in the Little Green Islands archipelago
Technically the unnamed rock at 46°51′35″N 56°05′57″W in the Green Island archipelago in Fortune Bay (https://maps.wikimedia.org/#12/46.8605/-56.1099) is, according to Google Maps, divided between Canada and Saint Pierre and Miquelon (France). Luis wiki (talk) 15:16, 25 December 2017 (UTC)
 * The March 27, 1972, agreement between Canada and France on their mutual fishing relations determined the demarcation of the limit of their territorial waters. This agreement confirmed Green Island’s location on the Canadian side of the boundary line. The boundary touches two Canadian islands at their low water marks (which are defined as the minimum low tide mark).
 * [ A U.S. State Department document] lists nine turning points on the boundary. Points (4) and (5) touch islands.
 * "'The Annex to the Agreement specified that,
 * 'The line which determines the limit of the territorial waters of Canada and the zones submitted to the fishery jurisdiction of France extends northward and westward in a series of eight connected straight lines joining the following points: ...
 * 'The line which determines the limit of the territorial waters of Canada and the zones submitted to the fishery jurisdiction of France extends northward and westward in a series of eight connected straight lines joining the following points: ...


 * 'Point (4) The low water mark on the south­ westernmost point on Enfant Perdu (Canada). Latitude 46°51'20'N., Longitude 56°05'30'W. approximately.


 * 'Point (5) The low water mark on the west point of the south-westernmost island of the Little Green Island group. Latitude 46°51'36'N., Longitude 56°05'58'W. approximately.'"


 * Point 4 is not equidistant from French and Canadian territory; it is located at the low-water mark off the southwest point of Enfant Perdu, a Canadian islet.
 * Point 4 and 5 are separated by a distance of 0.35 nautical miles. Point 5 is not equidistant from the two sovereignties, but is located at the low-water mark on the west point of the south-westernmost island of the Little Green Island group, which is Canadian.
 * If one does consider this demarcation to give rise to a land boundary, then it exists at one point on each of two islands. The question remains as to whether a point at low water mark is a point on land.
 * FURTHERMORE AND MORE IMPORTANTLY, addressing the subject of the original post above — The coordinate locations stated in the text of the 1972 agreement are described as approximate, meaning that the actual locations described in the wording govern the demarcation. The Google Maps aerial view displays the straight line boundary with endpoints at the stated approximate coordinates for Points 4 and 5, with this boundary line crossing one of the islets comprising the Little Green Islands. This line from Point 4 to Point 5 runs in a northwesterly direction. If one instead uses the Google Maps aerial view to inspect and specify accordingly Point 4 (”the south­ westernmost point”) and Point 5 (”the west point of the south-westernmost island”), the resulting boundary segment also crosses one of the rocky Little Green Islands, which are elongatedly shaped with major axis in a north-to-south-southeast direction. Therefore, a land boundary, estimated at 54 meters in length, seems to exist. Jeff in CA (talk) 06:32, 22 December 2023 (UTC)
 * Since the actually land border change based on the tides, and may even be completely submerged, there is the need to establish a clear definition of the length of the border. I see two propositions which make the most sense, either the length during the average tide level or the length at the lowest tide level. Furthermore due to the inconsistency in the height of the islands at the border there may be multiple meter-scale borders depending on the tides but it doesn't make sense to count them as separate borders. Megamasterbloc (talk) 17:24, 11 February 2024 (UTC)
 * Those lines demarcate the maritime border. France has ceded all these islands, they are 100% Canadian and there is no land border. 97.125.134.13 (talk) 23:40, 11 February 2024 (UTC)
 * source ? 149.88.27.194 (talk) 10:33, 13 February 2024 (UTC)
 * According to the exact wording of the 1972 agreement, the boundary is "The low 'water mark on the south-westernmost point of Enfant Perdu (Canada)." and "The low water mark on the west point of the south-westernmost island of the Little Green Island group." meaning that some part of the south part of the "south-westernmost island of the Little Green Island group" is in french territory and thus creating a definitive, undisputed, recognized, land border. The coordinates given, and used on most maps, are only approximates and the real delimitation points are based on physical features. The us document describing the Little Green Island group as presumably fully Canadian is thus wrong. The exact length of this border is difficult to determine. Megamasterbloc (talk) 11:26, 13 February 2024 (UTC)
 * This isn't just a little bit wrong, it's completely and unambiguously wrong.
 * You are trying to create a land border out of the definition of a maritime border. The maratime border doesn't apply on land (above the minimum low tide line).
 * The title of the US State Department document you're relying on is "LIMITS IN THE SEAS
 * No. 57
 * TERRITORIAL SEA BOUNDARY: CANADA-
 * ST.-PIERRE AND MIQUELON"
 * As the title indicates, it relates to maritime borders. The phrases "IN THE SEAS" and "TERRITORIAL SEA BOUNDARY" are our hints that the agreement relates to maritime, not land, borders. The document quotes Article 8 of the actual agreement between France and Canada as stating "The line defined in the annex to the present agreement determines, in the area between Newfoundland and the islands of Saint-Pierre and Miquelon, the limit of the territorial waters of Canada and of the zones submitted to the fishery jurisdiction of France."  (I haven't bothered to find the original agreement between France and Canada.  Like you, I'm trusting the accuracy of the US State Department's publication.) The agreement relates to territorial waters and fishery jurisdiction.  It does not affect the sovereignty of either nation over a single square milimeter of of its land territory.
 * The annex to the agreement mentioned in Article 8 of the agreement is where the points you claim create a land border between France and Canada are listed.  The US State Department document also quotes that annex as stating that "The line which determines the limit of the territorial waters of Canada and the zones submitted to the fishery jurisdiction of France extends northward and westward in a series of eight connected straight lines joining the following points:"  This makes clear (again) that the line being defined determines the limits of Canada's territorial waters and the zones submitted to French fishery jurisdiction.  It says nothing about either nation ceding any part of it sovereign lands.
 * You identified an interesting peculiarity of the definition of the Maritime border between France and Canada, although not likely one unknown to the drafters of the agreement. It's an interesting piece of trivia.  It's nice of you to share it.  It's not OK that you shared it by putting inaccurate information in this article claiming to have discovered a nonexistent land border between France and Canada.
 * If you want to confirm that France does not claim sovereignty over any part of Canada's Little Green Island Group, why don't you call one of the French police departments in Saint-Pierre and Miquelon and ask them if they have jurisdiction over the part of the rock or island you're referring to that is on the French side of the Maritime border and let us know what they say?

the border of Ukraine

Land?
The table lists Canada's border as 8,893 km. At Canada – United States border, you can see the international border lengths  of all of the states that border Canada. If you add up these lengths, you arrive at 8,890 km (Alaska 2,475 + Michigan 1,160 + Maine 983 + Minnesota 880 + Montana 877 + New York 716 + Washington 687 + North Dakota 499 + Ohio 235 + Vermont 145 + New Hampshire 93 + Idaho 72 + Pennsylvania 68). This is pretty  much in line with what is listed in the table. It is probably off due to rounding. But, that isn't my point. My point is much of Canada's 8,893 km of border is on water, not land. All of Michigan's 1,160 km of border is on water, all of Ohio's 235 km of border is on water, all of Pennsylvania's 68 km of border is on water, most of Minnesota's 880 km of border is on water, most of New York's 716 km of border is on water, and some of Washington's 687 km of border is on water. Canada's border length, therefore, is way overstated. 198.212.237.48 (talk) 10:26 am, 23 March 2011, Wednesday (4 months, 12 days ago) (UTC−7)


 * I believe borders on lakes, rivers, and other internal waters count as "land borders". There should be something in the intro to clear that up. Thanks for pointing it out. --Lasunncty (talk) 1:35 pm, 23 March 2011, Wednesday (4 months, 12 days ago) (UTC−7)
 * Thanks. Yes, I just got tripped up by this for the Tanzania-DROC border. The data in the table is misleading without this definition. Bderrett (talk) 22:52, 27 December 2014 (UTC)

Maritime neighbors
Why not include maritime neighbors? Iggi 01:35, 17 Jan 2005 (UTC)
 * Well, two reasons, really. First, because the list currently in was generated by a script that ran over the CIA pages, which doesn't contain that information (as far as I can see) and secondly, because I'm clueless as to what a maritime neighbor is. The old page had it, but I haven't yet overcome my laziness to merge the info from the old page into my "complete" list (which, as I said, was generated from scratch.). If you could point me to a place where I can get such info, I'll see what I can do. --gcbirzan (talk) 03:57, 17 Jan 2005 (UTC)
 * This list deals with land borders. Perhaps you can start a list on maritime borders, which is controversial because some countries are still in disagreement on where lies the border between high sea and EEZ. --Kvasir (talk) 21:35, 1 April 2008 (UTC)

Land borders should be only those cases where the land for each territory is in contact with other land. Azerbaijan and Turkmenistan are not considered to have a land border (the Caspian Sea is between them). Neither should the Democratic Republic of the Congo and Tanzania (Lake Tanganyika). I'd also argue that Botswana and Zambia do not have a land border. My test for if there is a land border between two territories that have only water between them is, is there a bridge or tunnel that spans the gap? If so, then there is a land border. Denmark-Sweden (bridge), Bahrain-Saudi Arabia (bridge), France-United Kingdom (tunnel). Because you can get from one to another via land transport. — Preceding unsigned comment added by 72.25.69.49 (talk) 19:53, 17 September 2012 (UTC)


 * Relevant point, but lakes and rivers are treated as land when it comes to borders. As for the Caspian Sea, its status as either lake or sea is currently disputed. --Lasunncty (talk) 08:31, 18 September 2012 (UTC)

European Union
Regarding Saccerzd's question posted in the edit history: The EU is an international organization and thus not a sovereign state.

Indian border
The Indian government maintains that it has a border with Afghanistan, since it believes the POK is a part of Indian Kashmir and POK has a northwestern border with Afghan. Should this be added too as a note since the featured article India talks about this oft ignored fact? Idleguy 08:40, 7 February 2006 (UTC)

How are border lengths measured?
In light of the work done by Mandelbrot in his paper How Long Is the Coast of Britain? Statistical Self-Similarity and Fractional Dimension and the work done by Lewis Fry Richardson, it seems that this article should mention how the borders are measured and what scale of measurement is used. I'm a little confused because it seems to me that stating a country's border as being x kilometres means nothing unless these things are specified. 18.248.5.226 05:25, 7 November 2006 (UTC)

Neutral territories
A number of countries do not actually border each other directly as there is a neutral territory between them, sometimes armed by UN forces. Examples of these are on Cyprus, Korea, UNDOF Zone, between Lebanon and Israel, between Gilbraltar and Spain, etc. How or should these be reflected? --Kvasir 06:15, 29 January 2007 (UTC)

European Union
How can Spain border Morocco, and Morocco border Spain - but the European Union not border Morocco? I always thought Spain was a full member of the European Union? 58.160.120.16 07:14, 16 May 2007 (UTC)

The part of Spain in Europe is part of the European Union, but does not border Morocco. The part of Spain in Africa borders Morocco, but is not part of the European Union. (Except for one part of France in South America, the European Union includes only land in Europe and islands. It does not include all parts of every member state.) 71.109.150.54 (talk) 22:58, 26 June 2011 (UTC)

Mongolia/Russia Border
Interesting to note that according to this list, Mongolia has a border of 3,543km with Russia, whilst in return, Russia has a border of only 3,485km! Sacre bleu! How can this be? Who created this list - and would you care to explain where exactly these 58km go? jkm 19:00, 17 May 2007 (UTC)

recent edit
Hello all,

I've done a big edit recently. Because of this, I think its fair I outline what I did. Here we go:
 * The islands of Bassas da India, Europa Island, Glorioso Islands, Juan de Nova Island, and Tromelin Island were listed separately. This is incorrect. Since February 2007, these islands are a part of the French Southern and Antarctic Lands.
 * In the same month, Saint Barthelemy and French Saint Martin spilt from Guadeloupe. This reduced the length of their border from 10.4 km to zero. Also this reduced the number of countries that bordered all of France from 11 to 10.
 * Saint Barthelemy and French Saint Martin have been added. The change in Guadeloupe's border goes to French Saint Martin.
 * I have also fixed the status of the other French territories. The edit of Clipperton Island's status is based of a recent change to ISO 3166-2. - Thanks, Hoshie 12:57, 26 January 2008 (UTC)

Kosovo
Kosovo is an independent and sovereign state. Therefore, it should appear on the "J-L" list, as it borders Albania, Montenegro, Serbia, and the Republic of Macedonia.-- A rbë r ( Let's Talk ) 11:30, 20 February 2008 (UTC)

Botswana / Namibia / Zambia / Zimbabwe quadripoint
I believe that it is very possible that there may be a quadripoint existing in the border among these countries, depending ultimately upon what the legal definition of the border is. If this is the case, then the Botswana/Zambia border should be zero length, and there should also be a Namibia/Zimbabwe border, also of zero length. See the Wikipedia articles for Kasane, Botswana and Kazungula, Zambia, as well as the Caprivi Strip article. Backspace (talk) 19:00, 22 March 2008 (UTC)
 * In theory, a zero length border means that a border does not exist between opposite countries. According to the CIA world fact book on Zambia, the border between Botswana and Zambia, if exist, is undelimited. The entry does not list Botswana as a neighbour country, however. See transnational issue for Zambia: https://www.cia.gov/library/publications/the-world-factbook/geos/za.html . If such a border exist, there would be no quadripoint. The Kazungula article says Bostwana fronts 1.6km of the Zambezi, which means the distance between the corners of Zimbabwe and Nambia is 1.6km apart. --Kvasir (talk) 21:24, 1 April 2008 (UTC)

Merger proposal from article on Longest border
The seems to contain an assertion that is incompatible with the facts in this article. I am not sure it is necessary. Deletion was proposed once before but didn't go through. I can't see why one would have a separate article and one that seems to contain inaccurate information. The fact about the longest shared border could be highlighted in this list. --Matilda talk 22:39, 31 March 2008 (UTC)
 * Given no reaction, I propose to action the merger --Matilda talk 04:07, 16 April 2008 (UTC)
 * Agreed to the merger. Only a few lines need to be highlighted to show the longest border. (WannabeAmatureHistorian (talk) 02:24, 17 April 2008 (UTC))

Sortable table
Instead of having the redundant section on List of countries and territories by length of land borders, we can combine all the sectionised tables to make one big table that can have customisable sorting by name, border length, and number of neighbours by the reader. --Kvasir (talk) 21:21, 1 April 2008 (UTC)


 * This doesn't work very well, since sorting does not understand the numbers as numbers, but rather each digit together So, after the 0s it starts with Israel at 1017 - the "lowest" number that starts with 1 - and ends with Burundi at 974!  Rendsburg (talk) 03:19, 5 December 2008 (UTC)

Proposed merge with List of countries by number of neighbouring countries

Also at some stage it would be good if all the flags were added but thats not too important.

Proposed merger from List of land borders with dates of establishment
That page is an orphan but has years and brief context for each of the borders. Better to integrate?User:LeadSongDog come howl  15:42, 26 March 2010 (UTC)


 * Hi LSD,
 * You requested a merger between List of land borders with dates of establishment and List of countries and territories by land borders. It's a nice idea, but both articles are very long. Isn't it better to keep these articles seperated? An alternative is to create a whole bunch of articles linked on the latter article, so you can see the history of all borders from one country very easily. But, the info is very subjective and will probably lead to a lot of conflicts. There was one already on the formation of the Bulgarian-Rumanian borders, which relativised the creation of this border, something which can be repeated a lot of times.Daanschr (talk) 17:42, 26 March 2010 (UTC)


 * Moved Daanschr's comment above to this page (where it belongs) from my talkpage.
 * I'd be sympathetic to eventually having a distinct article for each international border, though that would be a hefty undertaking. An intermediate option would be to break it down to subarticles by continent, though there will undoubtedly be a few disputes on the Europe/Asia and on the Africa/Asia divide relating to countries seen to span two continents. Choosing (in advance) underlying principles to guide the choices could help minimise the disputes. User:LeadSongDog come howl  18:16, 26 March 2010 (UTC)


 * There is an easy solution for that, since there are hardly any borders of country between two continents. I think the Sinai is Asia, so the Israeli-Egyptian borders are in Asia. Russia is in both Europe and Asia. Only the Caucasus is a mess. I thought, they is no official borders there between Europe and Asia. The best source would be the UN.Daanschr (talk) 07:52, 27 March 2010 (UTC)

I want to remove the merger template, if there isn't to be a merger. Of course a merger could aoccur, but merge it than.Daanschr (talk) 17:44, 30 March 2010 (UTC)
 * See WP:NODEADLINE. It takes a while to establish community intent for relatively obscure pages such as these. The function of the merger template is to draw participants into the merger discussion. So far, there's just the two of us involved, which doesn't really serve to establish concensus. User:LeadSongDog come howl  05:44, 6 April 2010 (UTC)


 * Comment. In theory, the two pages probably should be merged. However, I think that at this stage it would probably be difficult to do so, since the table on this page is already quite full. It might be a situation where it's OK to have the two separate pages just because of the amount of content. I guess you can put me down as an oppose for now, unless someone comes up with a brilliant proposal that resolves these issues. Good Ol’factory (talk) 06:06, 6 April 2010 (UTC)


 * Oppose: The list here is quantified quite well. E.g., we know just how long the various borders are. But the Dates of Establishment list contain vague info was to where the borders are (were) and just what countries border(ed) what. Perhaps footnotes can be added to this article.  But integrating the articles?  Good luck!  As far as the tag goes, this discussion is 8 months old.  Time to remove merge tag. --S. Rich (talk) 16:42, 8 December 2010 (UTC)

Indonesia and Malaysia

 * The table lists Indonesia's border with Malaysia as being 1782 km long and Malaysia's border with Indonesia as being 2019.5 km long. Now I don't know how long the border between these two countries is but I have to assume at least one of these figures is incorrect. And well beyond a reasonable margin of error.

Barak not an enclave
At the website of renowned expert, Jan Krogh (http://geosite.jankrogh.com/kyrgyzstan.htm):


 * "The     village of Barak is located on 40°40' N 72° 46' E. It is no geographical      exclave, but is surrounded by Uzbekistan in south, west and north. The use      of the term "exclave" may have been a misunderstanding due to      its location, relatively far from other Kyrgyz villages in the region.      Another      possibility is that it is referred to an ethnic exclave. Anyway as it in      January 2012 still has not been found on any map it is not likely this      exclave still is alive."

The mentions of Barak in the article as being an enclave should be removed.

If the border between those two entities is included in "shortest borders", surely it should qualify for "shortest border segment"? --Ulkomaalainen (talk) 23:40, 22 February 2017 (UTC)
 * User:Ulkomaalainen The border between County Leitrim and County Donegal might be similarly short. Maybe those entities should be listed too? Or should I use your terminology and call it a border between Leitrim and Ireland (Donegal)? Frenchmalawi (talk) 19:28, 14 April 2017 (UTC)
 * I may be misunderstanding what you're saying, but I am not trying to argue whether or not some border qualifies as a border for the list. However, I found it inconsistent that a border that qualifies for the list of shortest borders 'and' is short enough to also qualify for the "border segments" part, must qualify - or have a segment that qualifies - for the latter. So 'if' it is included in "shortest borders" it needs to go into "shortest border segments". Or be scrapped from "shortest borders". --Ulkomaalainen (talk) 14:13, 15 April 2017 (UTC)
 * I think we've both identified the same inconsistency. We are agreed. This is Wikipedia where politics runs rife. I leave it to others to tackle the substantive inconsistency. Going by the inclusion of the Chinese region of Macau, they'll be listing borders between U.S. states, UK regions, DPRK regions and Russian regions next.

Wrong length given for Ireland - United Kingdom border.
The border runs for a total of 499 km. The article reports a much shorter length. I will change this if no one objects. If there are objections, please let me know source for length given in the article. Frenchmalawi (talk) 19:24, 14 April 2017 (UTC)

Unique Land Borders
How is the number of unique land borders decided? For many countries (like Finland-Russia, Syria-Turkey) I can't figure out why it says there are multiple segments. Emetzold (talk) 21:53, 2 February 2018 (UTC)

Cote d'Ivoire's Border Discrepancy

Links to unique border pages
If someone has a lot of spare time on their hands, the links on here could be linked to the individual border pages: Category:International borders.WisDom-UK (talk) 20:48, 4 April 2020 (UTC)

Border lengths of Germany
The borders of Germany listed seem to contradict the source that is provided (https://www.cia.gov/library/publications/the-world-factbook/geos/ez.html). I can't really tell why this is, so unless anyone has any objection to me doing so, I will modify these border lengths to the lengths listed in the source. --DylanClarkWebb (talk) 16:34, 11 December 2020 (UTC)

Is this article just meant to spread misinformation?
These border lengths correspond to absolutely nobody's current estimates - not the CIA World Fact Book's, not the countries' governments', not the individual Wikipedia border articles', not anybody's, using any conceivable granularity of measurement. The lengths are under-reported across the board. Did somebody just use a ruler to come up with them? — Preceding unsigned comment added by 209.6.13.247 (talk) 23:26, 10 November 2021 (UTC)

Is a land border also over fresh water bodies, e.g. rivers?
Ref: 🇧🇼 Botswana – 🇿🇲 Zambia: 155 m near Kazungula, which is in the middle of the Zambezi river. --Eivindgh (talk) 20:22, 14 June 2022 (UTC)
 * Generally yes. It's land as opposed to maritime. CMD (talk) 11:06, 15 June 2022 (UTC)

Iran
The length of total land borders and each of them for Iran differs from the amounts which are given in the article Geography of Iran.

What's the reason for these differences?

Also, while it is mentioned that the Azerbaijan-Iran border has two segments, the number given is just for the length of border between Azerbaijan proper and Iran, excluding Nakhchivan Autonomous Republic. Aminabzz (talk) 13:13, 27 February 2023 (UTC)

Is Iran the only country in this article that its land border details differ from the amounts given in the article "Geography of X"? (X is any country) Aminabzz (talk) 13:16, 27 February 2023 (UTC)

Unrecognized Countries
Abkhazia and South Ossetia are currently the only unrecognized (as in, non UN member or observer) states featured on this list, (though Western Sahara is mentioned in the entries for bordering countries, it lacks one for itself)

Artsakh, Transnistria, Western Sahara, and Somaliland should be given their own sections for consistency. I can't find any info on the length of Artsakh's border, but the other three should be fairly easy to source (although the Moroccan berm probably complicates matters for SADR in figuring out the de facto border length)

Niue and the Cook Islands, counted on Wiki's own list of sovereign states, are also absent, but since they're island nations with no land borders, I don't think adding them is as pressing as the other four. Crazy Boris (talk) 19:57, 1 May 2023 (UTC)

Country borders not updated at all
Your primary source of data is cia.gov as listed in references. But you are not up to date with it. Almost every listed border there has different longness. Your data often mismatch when comparing border of country A with B and viceversa. On example Azerbaijan and Iran or Turkmenistan and Afganistan. I'm confused about your modus operandi. 95.168.105.16 (talk) 14:40, 11 October 2023 (UTC)

Bahrain-Saudi Arabia?
The two share a short border on an artificial islands near the middle of the King Faud Causeway, as seen here. Is there a reason for it not being included or is it an oversight? Nintentoad125 (talk) 19:13, 21 December 2023 (UTC)

Antartic Treaty and land borders
The Antartic Treaty only stop countries to make new claims in antartica but does not affect previous territorials claims. While the internal status of those territory depends on each country, it is clear that the borders as claimed just before the Antartic Treaty are legitimate land borders. As such I think it would be reasonable to include those borders, although the length and number of borders will most likely lead to even more discussions.

Treaty of Canterbury, France-UK border
As explained in France–United Kingdom border the Treaty of Canterbury define a land border in the Channel tunnel. Should this border be included and if it is, what would be it's length ? Megamasterbloc (talk) 17:43, 11 February 2024 (UTC)
