Ratio
The article currently contains a contradiction. It first says that the blocks are made with dimensions in the ratio 1:3:5. But then it says that the blocks are "five times longer than wide, and three times wider than tall," which means that the dimensions are in the ratio 1:3:15. [This] web page confirms that both Kapla Blocks and Keva Planks are made in the ratio of 1:3:15, rather than 1:3:5. I'll make the correction. NCdave 11:39, 8 February 2007 (UTC)

Weird, the ratios are neither by the looks of it. The flash "About Kapla" page ( http://www.kaplatoys.com/#wh_6 ) gives the dimensions (in inches) as 0.25 x 1 x 4.5 -- meaning the ratio is 1:4:18 (with "1" meaning "0.25 inches") 199.214.27.50 17:54, 12 March 2007 (UTC)
 * The dimensions 0.25" x 1" x 4.5" given on the website are apparently the result of sloppy conversion from metric units, as it contradicts the 1:3:15 proportions implied on that same website. Quoting the error in the article adds confusion, so I'm removing the content. 67.188.29.80 (talk) 21:05, 16 November 2008 (UTC)

Update: I can see the source for the 1:3:5 (i.e. 1 x 3 x 15) came from http://www.kapla.com/jeu_en.html -- While making the scale drawings he played with wooden blocks to see what the structure would look like. Soon he discovered that the blocks were not at all well adapted to building certain elements like floors, rooves and lintels. Unsatisfied with the possibilities of these blocks Tom van der Bruggen invented a plank based on the progressions of the uneven numbers 1:3:5. 3 thickness for one width and five widths for one length. This ratio between bricks and stones and beams and planks now opens a whole new way of building. With these identical planks the builder can construct with the precision of artwork and the stability of stones. 199.214.27.50 18:02, 12 March 2007 (UTC)
