What Is A 2x2 Passport Photo?
A 2x2 passport photo is the official US passport photo size. Here is what 2x2 actually means in inches, pixels, and millimeters — plus how to create one that meets every State Department requirement.
- 2x2 inches is the official US passport photo size
- Equivalent to 51x51 millimeters or 600x600 pixels at 300 DPI
- Used for US passports, visas, green cards, and citizenship
- Always square — never rectangular
What "2x2" means for passport photos
A 2x2 passport photo measures 2 inches by 2 inches. It is the official US passport photo size set by the State Department and used for all US passport applications, renewals, visa applications, green card applications, and naturalization filings.
The 2x2 size is always a perfect square, never a rectangle. International passports often use rectangular sizes (the EU standard is 35x45mm, for example), but US passports are uniquely square.
2x2 in every unit
Different applications and printing services use different units. Here are the exact 2x2 passport photo dimensions in every common measurement:
- Inches: 2 x 2 (exactly)
- Millimeters: 51 x 51
- Centimeters: 5.1 x 5.1
- Pixels at 300 DPI: 600 x 600
- Pixels at 600 DPI: 1200 x 1200
- Aspect ratio: 1:1 (square)
Head size within the 2x2 frame
The 2x2 photo size is only part of the requirement. The head must also be properly sized within the frame. The State Department specifies that the head — measured from the bottom of the chin to the top of the head — should be between 1 inch and 1.375 inches tall.
The eyes should be between 1.125 and 1.375 inches from the bottom of the photo. This positions the face in the upper-center portion of the frame, with some white space above and below the head.
- Head height: 1 to 1.375 inches (25 to 35mm)
- Eye position: 1.125 to 1.375 inches from bottom
- Face centered horizontally
- Roughly 50% of the photo height is the head
Where the 2x2 size is used
The 2x2 size is the standard for all US federal photo identification applications. It is used for US passports (book and card), US visas, USCIS green card applications, USCIS citizenship/naturalization applications (N-400), and several state-level applications like enhanced driver licenses.
A few non-US applications also accept 2x2 — but most international passports use different sizes. Always check the specific requirements of the application before reusing a 2x2 photo for non-US documents.

Frequently Asked Questions
How many pixels is a 2x2 passport photo?
600 x 600 pixels at 300 DPI is the standard. For higher-quality printing, 1200 x 1200 pixels at 600 DPI also works.
Can I print 2x2 photos on a 4x6 sheet?
Yes. A 4x6 sheet fits exactly six 2x2 photos in two columns of three. FastPassPhoto includes a 4x6 print template arranged this way.
How do I print a 2x2 passport photo?
Print the 4x6 template at any pharmacy photo lab (Walgreens, CVS, Walmart) for under a dollar, then cut along the printed lines. Home printing works on glossy 4x6 photo paper.
Why is the US passport photo size 2x2?
The 2x2 size was standardized decades ago and matches the dimensions used by most US biometric photo systems. It allows for clear facial recognition while remaining a manageable size for printing and document attachment.
