What does 2x2 photo size mean?
It means the photo is exactly two inches wide and two inches high. Because the format is square, it behaves differently from the more common 35x45 mm portrait format used by many non-U.S. documents.
2x2 Passport Photo Size: Exact Dimensions, Pixels, cm, and Print Tips
A 2x2 photo measures 2 x 2 inches, which is the same as 51 x 51 mm or about 5.1 x 5.1 cm. This exact-size format is common for U.S. passport, visa, and green card style photo requirements, but the final digital rules can still vary by document and submission system.

Square format. Do not stretch or crop it into a portrait ratio.

Also approximately 5.1 x 5.1 cm.
Digital caution
Pixels vary
Print pixels are not always the same as a destination system's upload rules.
2x2 is a square output, not just a generic passport crop
The job of this page is exact-size ownership: 2 inches wide, 2 inches high, and preserved through export or print. It should not compete with the broader passport-size guide or document-specific pages.
For print, preserve the physical 2 x 2 inch size and disable printer scaling. For digital upload, still check the destination system's pixel and file-size rules.

Exact 2x2 output
Use this when the document explicitly asks for a 2 x 2 inch photo.
3.5 x 4.5 cm
35x45 alternative
Use the metric page instead when the requested photo is vertical.
A 2x2 crop is not a universal digital submission file
Use this page for exact physical size. For U.S. visa and Diversity Visa workflows, follow the separate pixel and file-size rules. For U.S. passport online renewal, upload the original, unedited capture required by the State Department instead of a processed PhotoID export.
Create the exact square format after identifying the document flow
Use the 2x2 preset for a compatible print or digital workflow, then compare the export with the document-specific owner page. Do not use it for U.S. passport online renewal.
- Start from the 2x2 preset instead of manually dragging a crop box.
- Check background, lighting, face position, and image clarity before export.
- Use a print-ready layout when the workflow needs a physical photo.
2x2 photo size in pixels
For printing at 300 DPI, a 2x2 image is about 600 x 600 pixels. Treat that as a print-preparation reference, not as a universal digital-upload rule.
Which documents use a 2x2 photo?
- U.S. passport photo requirements
- Many U.S. visa-related photo flows
- Form I-485 printed photos and Diversity Visa entry files
How to print a 2x2 photo correctly
- Print at 100% scale.
- Disable fit-to-page or automatic scaling.
- Use a print-ready layout instead of dragging the image into a document manually.
- Check the final physical size after printing.

Common 2x2 photo mistakes
- Using a square crop with the wrong physical dimensions
- Printing with scaling enabled
- Treating a social-media square image as a valid document photo
- Assuming every 2x2 file is ready for every digital submission system
- Using the right size but the wrong background or face framing
- Confusing 2x2 with 35x45 or other passport-size editor presets
Prepare the right 2x2 result for a compatible workflow
Use the exact-size preset, check common issues, and export only after confirming whether the destination needs print or a supported digital file.
Choose the 2x2 format
Start with the exact-size preset so the app applies the correct square format.
Prepare the framing
Align the face and crop before export so the final image stays usable.
Check common issues
Review background, lighting, face position, and image quality before continuing.
Export for the identified workflow
Choose print or a supported digital format only after checking the destination-specific owner page.
