Marc is correct, there are measurements on most items usually in centimeters so when I posted the pics I just divided by 2.54 and entered them as inches (I originally did that because it was easier for me) but you should be aware that height and width given measurements might not be the bow....they may be the space occupied by the bow, sometimes not so. But if you come across a measurement of height of 6 to 8 cm be aware that the bow is probably not 2.36 - 3.15 inches thick.
Marc told you correctly as stated, I just want to point out that curators measurements may not be the same as what we as bowyers need.
Thanks Marc
