Calculate depth of field from aperture, focal length, sensor size, and subject distance. See near and far focus limits for sharp photos.
Calculate correct exposure with the exposure triangle. Set ISO, aperture, and shutter speed for balanced photos in any lighting situation.
Convert focal length between camera sensor sizes using crop factor. Find full-frame equivalent focal length for APS-C, MFT, and more.
This tool applies a standard formula from the relevant domain. The computation is deterministic — given the same inputs, the result is always identical. The formula accounts for the primary variables that determine the output.
Print Size (in) = Pixels ÷ DPIThe calculation requires: Image Width, Image Height, Print DPI. Each parameter contributes to the final result according to the formula above. Accuracy depends on the precision of your input measurements.

Check the expected unit for each input field (shown as suffix). Converting between imperial and metric units before entering values prevents calculation errors.
When a formula combines multiple measurements, all inputs must use compatible units. Convert everything to the same system (metric or imperial) before calculating.
Calculate print dimensions and DPI from image pixel resolution. Free print resolution calculator for photo prints, posters, and professional lab output. It applies the calculation formula (Print Size (in) = Pixels ÷ DPI). For example: 24 mp image at 300 dpi — A typical use case demonstrating the calculator with representative values.
