2×2 Inch Photo
A 2×2 inch photo is 51×51 mm — the size used for US passports and visas and asked for on many US forms, from USCIS applications to daycare and school enrolment. SnapID checks your photo and cuts it to 2×2 with the head at the right size, at print resolution.

Don't let your photo get rejected
These are the most common rejection reasons — SnapID checks for them before you pay.
Wrong background color
Using white when cream is required, or off-white when pure white is needed. Our AI detects and flags background issues instantly.
Shadows on face
Overhead or side lighting creates shadows that cause rejection. SnapID checks for even lighting on both sides of your face.
Incorrect head position
Head tilted, turned to the side, or not centered in the frame. Our AI measures exact positioning against official rules.
Eyes not visible
Closed eyes, hair covering eyes, or glare from glasses. Especially common with babies — our AI checks for this.
Wrong dimensions
Each country has exact size requirements. SnapID auto-crops to the precise dimensions needed for your destination country.
Blurry or low-resolution photo
Out-of-focus or heavily compressed photos get rejected. SnapID checks sharpness and resolution before you pay.

Tips for a perfect photo
Exact size
+
2 × 2 inches (51 × 51 mm). At 300 DPI that's 600 × 600 pixels. For US passports and visas the head, from chin to top of hair, is 1 to 1⅜ inches (25–35 mm).
Where it's used
+
US passports and visas, many USCIS forms (check the instructions for your form), and US daycare, school and club forms that ask for a “passport-size” photo.
Printing
+
One 4×6 inch print fits 2 photos with cutting margins; an A4 sheet fits 15. Print at actual size (100%) at any photo kiosk or at home, then cut along the grey lines.
Before you use it for a US passport
+
The State Department asks for an original, unedited photo and checks for digital edits. SnapID cleans up the background, so for the best chance of acceptance take your photo against a plain white or off-white wall.
Digital version
+
The DS-160 visa form needs a square JPEG of 600–1200 pixels, no larger than 240 KB. That file is included with your photos.
