3:2 is an aspect ratio — these are the pixel sizes people most often export after cropping.
| Use | Pixels (W × H) |
|---|---|
| 4×6 print (300 DPI) | 1800 × 1200 |
| DSLR full frame | 6000 × 4000 |
3:2 matches a standard 4×6 inch print exactly, so crop to 3:2 before sending photos to a print lab to avoid auto-trimming.
Most DSLR and mirrorless cameras already shoot 3:2 — use this crop to re-frame or straighten without changing the native ratio.
For a sharp 4×6 print, keep the cropped image at 300 DPI: that means at least 1800×1200 px.
3:2 is slightly less wide than 16:9 — a good middle ground when 16:9 feels too cinematic for a photo.

Use the Crop tool to crop your image to 3:2, or browse all aspect ratios.
3:2 is the classic photography ratio used by 35mm film and most DSLR/mirrorless cameras. Its width is 1.5× its height — for example 1800×1200 px or 6000×4000 px straight out of camera.
A 4×6 print is exactly 3:2. Open the SammaPix crop tool, choose 3:2, frame your shot, and export at 300 DPI (at least 1800×1200 px). This prints edge-to-edge with no cropping by the lab.
3:2 is wider and is the standard for DSLR cameras and prints. 4:3 is taller and is common on phones, older cameras, and Micro Four Thirds. 3:2 suits classic photography; 4:3 captures more vertical detail.
Cropping removes pixels outside the frame, so the kept area keeps its original sharpness. As long as the remaining crop is at least 1800×1200 px, it prints beautifully at 4×6 inches and 300 DPI.
Crop to 2:3
The vertical version of 3:2 — perfect for Pinterest pins (1000×1500 px), portrait photo prints, and posters where height carries the composition.
Crop to 4:3
The classic standard — perfect for traditional photography, iPad and tablet screens, older monitors and TVs, and many presentation templates.
Crop to 16:9
The widescreen standard — perfect for YouTube thumbnails and videos (1280×720, 1920×1080), presentation slides, desktop wallpapers, and any 16:9 display or player.
Crop to 5:4
The classic print ratio — perfect for 8×10 inch photo prints (the most common framed portrait size) and large-format photography.
