Print Size From Pixels Calculator
Calculate print width from pixel width and target PPI.
How to use Print Size From Pixels Calculator
1. Enter Pixel Width, Target PPI, Print Size Unit. 2. Choose inches, cm or mm for the physical size. PPI always means pixels per inch; centimetres use exactly 2.54 per inch and millimetres 25.4 per inch. Match the same axis. This is a numeric estimate, not a file/metadata transformation or printer guarantee. 3. Select Calculate or press Enter. 4. Select Copy result to copy the answer, or Reset to clear the form and result.
Why use this tool?
Choose inches, cm or mm for the physical size. PPI always means pixels per inch; centimetres use exactly 2.54 per inch and millimetres 25.4 per inch. Match the same axis. This is a numeric estimate, not a file/metadata transformation or printer guarantee.
How the calculation works
Physical inches = pixels along one axis ÷ pixels per inch. Choose inches, cm or mm for the physical size. PPI always means pixels per inch; centimetres use exactly 2.54 per inch and millimetres 25.4 per inch. Match the same axis. This is a numeric estimate, not a file/metadata transformation or printer guarantee. Counts and dimensions use the declared rounding convention; other numbers display up to three decimal places where applicable. Nonzero subsecond durations are labelled. Durations round to the nearest second; nonzero subsecond durations are labelled. File-size output units are decimal. Changing an input label does not convert filled values.
Example
Worked example: Pixel Width = 3000; Target PPI = 300; Print Size Unit = "inches". Result: 10 in.
Practical tip
Check the input labels and assumptions against the print size from pixels task before reusing the number.
