Convert an image to 3:2 ratio
3:2 is the native sensor ratio of most full-frame and APS-C DSLR/mirrorless cameras, inherited directly from 35mm film. If a photo was shot straight out of a dedicated camera (not a phone) and hasn't been cropped, it is very likely already 3:2 — this tool is mainly useful for matching other images to that same ratio for a consistent gallery or print set.

How to convert your image to 3:2 ratio

Phone photos at 4:3 need only a small trim to reach 3:2 — crop mode handles this cleanly.
For 16:9 sources, pad mode keeps the full wide frame visible inside the 3:2 canvas.

Why do you need to convert to 3:2 ratio?
If you shoot with a DSLR or mirrorless camera, your photos are already 3:2 — so converting is rarely needed for your own shots. The main reason to convert TO 3:2 is consistency: mixing phone photos (4:3 or 16:9) with camera shots in a gallery or print set creates mismatched frames. Converting everything to 3:2 solves that in one step.
Common pixel sizes for this ratio (3:2)
Where this ratio is used
- Native output from DSLR and mirrorless cameras (uncropped)
- Standard photo prints (4×6 in, 6×4 in)
- Travel and landscape photography portfolios
- Stock photography submissions requiring camera-native ratios
Crop or pad — which should you use for this ratio?
Because 3:2 is already the native shape for most dedicated cameras, you'll typically only convert something INTO 3:2 — usually a phone photo you're matching to a set of camera shots. A standard crop works for most images; switch to padding only when the phone photo is framed tightly and trimming further would cut into something near the edge.
How this ratio compares to a similar one
3:2 vs 5:4: 3:2 is wider and matches camera sensors directly; 5:4 is closer to square and matches the classic 8×10 inch frame. If you're printing for a store-bought frame, check the frame's ratio first since cropping from 3:2 to 5:4 removes a noticeable strip from one side.
Frequently asked questions
How is 3:2 different from 4:3?
3:2 is slightly wider — it's the ratio used by cameras with sensors derived from 35mm film, while 4:3 comes from older TV and compact-camera sensors. The difference is subtle but noticeable in how much is cropped from the long edge.
Why would I need to convert TO 3:2 instead of from it?
If you're combining photos from a phone (often 4:3 or 16:9) with photos from a DSLR (3:2) into one print set or gallery wall, converting all of them to 3:2 keeps the framing consistent.
Does converting to 3:2 affect photo print quality?
No — as long as the output resolution stays high enough for your print size (roughly 300 pixels per inch), converting the ratio with a crop or pad does not reduce sharpness or quality.
Why does my phone photo not match 3:2 by default?
Most phone cameras default to 4:3 or capture at sensor ratios closer to 4:3, not 3:2, because phone camera sensors are physically smaller and shaped differently from DSLR sensors.
Is 3:2 a good ratio for a photography portfolio website?
Yes, since it's the native output of most cameras, displaying photos at their original 3:2 ratio avoids unnecessary cropping and keeps the photographer's original framing intent.
