The photos of the college entrance examination are generally blue, and one-inch and two-inch photos should be prepared. The admission notice of university admission photos will indicate 1 inch, and the background color can be blue or red. White background is generally used to move accounts. If there is no need in this respect, it is not necessary.

The photo size of the student ID card is generally 2 inches or 1 inch. It is the identity certificate issued by the school to the students who have obtained the student status. One-inch color or black-and-white photos stamped with the school seal are not allowed to be painted at will.

One-inch photo must be a recent bareheaded color head portrait, which accounts for 2/3 of the photo size. White background, no border. The image is clear, with rich layers, natural appearance and no obvious deformation. The photo size is 32 mm x 26 mm, the two-inch photo (a 5-inch top row of 4 photos) is 3.5*5.2cm, and the resolution is above 600*400.
