A 4×6 photo measures exactly 4 inches by 6 inches (10.16 × 15.24 cm, or 101.6 × 152.4 mm). At 300 DPI, the standard for high-quality printing, it requires 1200 × 1800 pixels.
A 4×6-sized photo uses a 3:2 aspect ratio, which matches most DSLR cameras and traditional 35mm film. You must understand its measurement, usage, and pixel count before using it everywhere.
If you just need the exact size details quickly, here’s everything in one place:

- Smaller than a standard A5 notebook
- Roughly the size used in most printed photo albums
In practical terms, 4×6 is the “default photo size” most people think of when printing pictures. It’s large enough to capture meaningful detail but compact enough to store, frame, or share easily.
