How many inches of photos do you need for marriage registration photos?

I need three 2-inch photos. According to the provisions of the relevant civil affairs departments, it is written in Article 22 of the Provisional Regulations on Marriage Registration that the parties involved in marriage registration should submit recent bareheaded photos of both parties. At the same time, according to the provisions of the Marriage Registration Service Standard System, the photo specifications of the marriage certificate are color photos of both parties, the background is blue or red, and the size (height× width) is 3.6cm×5.2cm. Therefore, in general, the photo size of the marriage registration photo is 2 inches, which is what we call 3.6cm×5.2cm. As long as you go to any photo studio, you only need to tell the photographer that you need to register 2 inches. Photographers know the size of photos best. Marriage registration photos should not be too small or too large. Because the marriage registration photo needs to be posted on the marriage certificate, after all, the marriage certificate is only12.7cm * 9.3cm. If the photo of the marriage registration photo is too large, it is not suitable to be posted on the marriage certificate.
