What is the pixel size of an inch photo and the resolution of the photo?

The commonly used 1 inch photo has a size of 2.5*3.5cm, a specification of 358 pixels (width) ×44 1 pixel (height) and a resolution of 350dpi.

One-inch photos are generally used as identification photos. All photos must be recent bareheaded color headshots, with heads accounting for 2/3 of the photo size, no borders, clear images, rich layers, natural expressions and no obvious distortion.

The so-called ID photo is a photo used as a proof of identity. The ID photo requires a bareheaded (bareheaded) front photo. The outline of a person's ear and the place equivalent to a man's Adam's apple should be seen normally in the photo. The background colors are mostly red, blue and white.

Extended data:

A, one inch bareheaded photo standard requirements:

1, photo specification: 358 pixels (width) ×44 1 pixel (height), resolution 350dpi;;

2. Color mode: 24-bit RGB true color;

3. Requirements: Citizens' recent color photos have a pure white background, no standard clothes or white tops, and residents who often wear glasses should wear glasses, requiring clear images, rich levels, natural expressions and no obvious distortion;

4. Head Size and Location: In order to ensure the photo quality and the uniformity of head size, angle, posture and color, the Ministry of Public Security has formulated and issued the Technical Standard for Digital Photographs for ID Card Making (GA46 1-2004). All photos must be recent bareheaded color headshots, accounting for 2/3 of the photo size, with clear images, rich layers, natural expressions and no obvious distortion, and the photo size is 32 mm× 26 mm

Second, the matters needing attention in photo shooting:

1. First tell the photographer what specifications the photos you want are, including size, number of photos, background color of photos, specific use, and film production method (is it a photo that must be developed or developed normally? )。 Of course, when can I get the photos I want?

2. A neat hairstyle is very important. Men should shave, their beards should be neatly trimmed, and women should put on some simple makeup. There is no luster on the face.

3. The clothing should be as stiff as possible, and there should be no obvious folds.

4. Be energetic when taking photos.

5. Don't be nervous when taking pictures. Now most of them use digital cameras, so don't worry, you can't express yourself well and waste the photographer's film.
