About this tool
See how camera sensor formats compare, drawn to scale: medium format, full frame, APS-H, APS-C, 4/3″, 1″ and the small sensors used in compact cameras and phones. Pick the formats to overlay, centered or lined up in a corner.
The table lists each format’s size, diagonal, area and crop factor, and the calculator shows the full-frame equivalent focal length and depth of field for any lens.
- Works on your device. Nothing is uploaded.
- Free, with no sign-up and no watermark.
- No limits on file count or size beyond what your device can handle.
Questions and answers
What is the crop factor?
It is how many times smaller a sensor’s diagonal is than full frame. Multiply a lens’s focal length by it to get the field of view it gives on full frame.
What does a size like 1/2.3″ mean?
These “inch” names come from old video tubes and don’t match the real size: a 1/2.3″ sensor is only about 6.2 × 4.6 mm. That’s why the chart shows the actual dimensions.
Does a bigger sensor give better photos?
A bigger sensor collects more light, which means less noise in dim light and a shallower depth of field at the same framing. Lenses and processing matter too.
