Tip

300 DPI is the industry standard for passport photo printing. The US State Department requires a minimum of 600×600 px for the 2×2 inch format, which is exactly 300 DPI.

How to Convert Photo Size to Pixels

DPI (dots per inch) determines how many pixels fit in each inch of the printed photo. Higher DPI = more detail = larger file.

Inches → Pixels

px = inches × DPI
2 in × 300 DPI = 600 px

Millimeters → Pixels

px = (mm ÷ 25.4) × DPI
45mm ÷ 25.4 × 300 = 531 px

Centimeters → Pixels

px = (cm ÷ 2.54) × DPI
4.5cm ÷ 2.54 × 300 = 531 px

Why Pixel Count Matters for Passport Photos

Passport offices don't ask for DPI — they ask for pixels. Here's what each agency requires:

Pixel Size FAQ

How many pixels is a 2×2 inch photo?

A 2×2 inch photo is 600×600 pixels at 300 DPI (the standard for print quality). At 96 DPI (screen), it is 192×192 pixels. At 600 DPI (high-quality print), it is 1200×1200 pixels. For US passport photos, always use 300 DPI — the State Department minimum is 600×600 px.

What is 35mm × 45mm in pixels?

35mm × 45mm equals 413 × 531 pixels at 300 DPI. At 150 DPI it is 207 × 266 px. At 600 DPI it is 827 × 1063 px. To calculate: multiply mm by (DPI ÷ 25.4). So at 300 DPI: 35 × (300÷25.4) = 413 px wide.

What DPI should a passport photo be?

300 DPI is the standard minimum for passport photos accepted worldwide. The US State Department requires at least 600×600 pixels for the 2×2 inch format (which equals 300 DPI). Professional photo labs print at 300–600 DPI. Never submit a passport photo below 150 DPI — it will appear blurry when printed.

How do I convert inches to pixels?

Multiply the dimension in inches by the DPI. Formula: pixels = inches × DPI. Examples: 2 inches at 300 DPI = 600 px. 1.38 inches (35mm) at 300 DPI = 414 px. At 72 DPI (screen): 2 inches = 144 px. Use the calculator above to convert any size instantly.

How do I convert millimeters to pixels?

Divide millimeters by 25.4 to get inches, then multiply by DPI. Formula: pixels = (mm ÷ 25.4) × DPI. Example: 45mm at 300 DPI = (45÷25.4) × 300 = 531 pixels. For centimeters, divide by 2.54 instead of 25.4.

What is 2×2 inches at 300 DPI in pixels?

2×2 inches at 300 DPI = 600×600 pixels. This is the required minimum resolution for US passport photos submitted online (State Department photo upload tool). The total pixel count is 360,000 pixels (0.36 megapixels).

What is 50×70mm in pixels?

50×70mm at 300 DPI = 591 × 827 pixels. This is the Canadian passport photo size. At 150 DPI it is 295 × 413 px. Always use at least 300 DPI for any print passport photo submission.

Why is my photo rejected for being too low resolution?

Most passport photo services require a minimum of 300 DPI. If your photo is lower resolution, the printed output will appear blurry or pixelated. A 2×2 inch photo at 72 DPI is only 144×144 px — far too low for print. Always ensure your photo is at least 600×600 px for the 2×2 format, or 413×531 px for 35×45mm.
