Most commonly used Passport photograph size

A lot of people are now printing passport size photographs at home. One of the things I keep forgetting is the most common size for the same. Turns out that the most common size is 3.5cm x 4.5cm, or, around 1.37in x 1.78in. This translates to approximately 412 x 530 pixels.

BTW, check out the new calculator in google using a current browser. Try a search like “3.5 cm in inches” and the new, changed, look is nice.
