We have taken many photos since childhood. Before, I only knew the size of photos, but I didn't know how many inches a photo was, so I went to consult my friend who opened a photo studio. It is clear that the photo size comparison table is as follows:
1 inch photo: 2.5cm*3.5cm, ID photo.
2 inch photo: 3.5cm*5.3cm, standard 2 inch photo.
3-inch photo: 8.9 cm * 6.0 cm
4-inch photo:10cm * 7.6cm.
5-inch photo: 12.7cm*8.9cm, the most common photo size.
6-inch photo: 15.2cm* 10.2cm, which is a common photo size in the world.
7-inch photo: 17.8cm* 12.7cm?
8-inch photo: 15.2cm*20.3cm, which is about half of A4 printing paper.
9-inch photo:15.2cm * 22.8cm.
10 inch photo: 20.32cm*25.40cm
