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.
Max print = √(Megapixels × 1e6) ÷ DPIThe calculation requires: Megapixels, Target DPI, Aspect Ratio. 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 maximum print size at a given DPI from camera megapixels. Free megapixel print size calculator for camera exposure, lens settings, and print sizing. It applies the calculation formula (Max print = √(Megapixels × 1e6) ÷ DPI). For example: 24 mp at 300 dpi, 3:2 — A typical use case demonstrating the calculator with representative values.
