Use this passport photo size in pixels calculator to estimate pixel dimensions for 2x2 inch passport-style photos at common DPI settings.
Passport Photo Size - Inches
Passport Photo Size Dimensions
The physical size for passport photo size is 2 x 2 inches, or about 5.08 x 5.08 cm. In millimeters, that is approximately 51 x 51 mm.
Passport Photo Pixel Dimensions
Passport-style photos often use a 2 x 2 inch layout, but exact official requirements can vary by country, agency, and application type. Pixel size is only one part of a compliant photo.

Passport Photo Size Pixels Chart
Use this chart to compare passport photo size pixel dimensions at common DPI settings. For most sharp prints viewed up close, 300 DPI is a common target.
| DPI / PPI | Pixel Width | Pixel Height | Pixel Dimensions |
|---|---|---|---|
| 72 DPI | 144 px | 144 px | 144 x 144 px |
| 96 DPI | 192 px | 192 px | 192 x 192 px |
| 150 DPI | 300 px | 300 px | 300 x 300 px |
| 300 DPI | 600 px | 600 px | 600 x 600 px |
| 600 DPI | 1200 px | 1200 px | 1200 x 1200 px |
How to Calculate Pixels from DPI
To calculate pixel dimensions, multiply the size in inches by the DPI. If the width is 2 inches and the resolution is 300 DPI, the pixel width is 2 x 300 = 600 pixels.
pixels = inches x DPI inches = pixels / DPI Which DPI Should You Use?
For quick screen previews, 72 or 96 DPI is often enough. For everyday printing, 150 DPI can work for items viewed from a little distance. For sharp photos, documents, and design work viewed up close, 300 DPI is a common target.
Higher DPI values such as 600 DPI create larger image files and are usually used when the printer, artwork, or production workflow needs extra detail.
Passport Photo Caution
Check the official photo rules before submitting. Background color, head size, face position, shadows, glasses, file format, and compression rules can matter as much as the pixel dimensions.
Pixel dimensions alone do not guarantee print quality. The original image or artwork must have enough real detail at the final print size; simply enlarging a small file increases the numbers but does not add true sharpness.

Compare passport photo size with related photo size options. The pixel values below use 300 DPI so you can quickly see how much image resolution changes from one size to another.
| Size | Inches | Pixels at 300 DPI | Aspect Ratio |
|---|---|---|---|
| Passport Photo Size | 2 x 2 in | 600 x 600 px | 1:1 |
| 4x6 Photo Size | 4 x 6 in | 1200 x 1800 px | 1:1.5 |
| 5x7 Photo Size | 5 x 7 in | 1500 x 2100 px | 1:1.4 |
| 8x10 Photo Size | 8 x 10 in | 2400 x 3000 px | 1:1.25 |
| 2x2 Photo Size | 2 x 2 in | 600 x 600 px | 1:1 |
Best DPI Use Guide
The right DPI depends on how the file will be used. A web preview, home print, photo print, and professional file do not always need the same pixel dimensions.
| DPI / PPI | Best Use | Notes |
|---|---|---|
| 72-96 DPI | Screen preview and web layout | Useful for digital viewing, but usually too low for sharp close-up printing. |
| 150 DPI | Basic prints and larger items viewed from a distance | Can work for posters or drafts, but fine text and photos may look softer. |
| 300 DPI | Sharp photos, documents, cards, and close-viewed prints | A common target for high-quality print files and photo printing. |
| 600 DPI | High-detail scanning, line art, and production workflows | Creates larger files and is not always needed for normal photo prints. |
Common Print Size Mistakes to Avoid
- Do not assume changing DPI alone improves quality. The image needs enough real pixels and detail.
- Do not confuse screen size with print size. Pixels describe the file; inches, cm, and mm describe the physical print.
- Do not forget bleed, margins, and safe areas when preparing files for professional printing.
- Do not upscale a very small image and expect it to become sharp. Resizing can increase dimensions, but not true detail.
- Do not submit a final print file without checking the printer's required file type, color mode, and resolution.
Frequently Asked Questions
What is passport photo size at 300 DPI?
Passport Photo Size at 300 DPI is 600 x 600 pixels. This is calculated by multiplying the width and height in inches by 300.
Is DPI the same as PPI?
DPI and PPI are often used together in print-size calculators. PPI usually describes image pixels per inch, while DPI can describe printer dots per inch. For simple print-size planning, the same number is commonly used in the calculation.
Is 300 DPI good for printing?
Yes, 300 DPI is a common target for sharp prints viewed up close, including photos, documents, cards, and many design projects.
Can I print with fewer pixels?
Sometimes. A lower pixel count may still look acceptable for posters or prints viewed from farther away. For close viewing, use a higher DPI target when possible.
