4x4 Photo Size: Dimensions in Inches, cm and Pixels (and How to Crop Square)

A 4x4 photo is 4 × 4 inches (10.16 × 10.16 cm), which is 1200 × 1200 pixels at 300 DPI. It is a square print, so any rectangular photo must be cropped to a 1:1 ratio first.

How to Crop a Photo to 4x4 Without Distorting It

1. Pick the square size from the short side. A 4000 × 3000 photo crops to 3000 × 3000; a 1920 × 1080 image crops to 1080 × 1080.
2. Crop to 1:1. Use the crop tool's square option on your phone, Photos, Preview, Paint or any editor, and move the frame over your subject.
3. Resize to 1200 × 1200. For a 4 × 4 inch print at 300 DPI. Never stretch a rectangle into a square: it distorts faces.
4. Save as JPG or PNG at high quality for the print shop.

If you do not want to lose the sides, add padding or a background color instead of cropping; see how to change a photo's background color.

What If the Square Is Too Small to Print?

Below about 800 × 800 pixels a 4 × 4 print looks soft. Enlarge the cropped image with an AI upscaler (2x free, 4x on Pro), then export at 1200 × 1200. If it is also blurry or noisy, fix that first with the blurry photo fixer or enhancer.

4x4 Photo vs Passport Photo

A 4x4 print is not a passport photo. A US passport photo is 2 × 2 inches with a pixel range of 600 × 600 to 1200 × 1200 for online submission, and requirements differ by country. If you only need a white background, see white passport photo background. Always check your issuing authority's current rules.
