I keep seeing images that include "U.S. Quarter coin shown for scale". I have never been to the U.S., and I can only guess what size a U.S. quarter is. Even the U.S. Quarter coin article doesn't tell me its dimensions! (I know, I can fix that if I do the research.) It would be better if people were to use more universal items for scale reference, such as: matchstick, pencil, BIC pen, new pair of shoelaces, CD. Perhaps photographers could even use a ruler (but it should stated whether the ruler is metric or imperial, ideally it should have both). I realise that images that are already uploaded can't be changed unless someone provides a replacement image, but perhaps a guideline could be introduced for photographers.
