About this converter

This tool converts paper size dimensions between all common units used in printing, design, and engineering. Enter a width and height in any unit and the tool instantly shows the equivalent in every other unit.

Formula for pixels: pixels = (mm / 25.4) × DPI. For example, A4 width (210 mm) at 300 DPI = (210 / 25.4) × 300 ≈ 2480 pixels.

Formula for inches: inches = mm / 25.4. A4 width (210 mm) ≈ 8.27 inches.
