How to use the Print Size Converter
- Choose the resolution: 300 DPI for high-quality print, 150 DPI for large posters viewed from a distance, or enter a custom value.
- Type a width or height in any unit — pixels, mm, cm or inches.
- The other units update instantly.
- Use the common print sizes table to see how many pixels you need for A4, visiting cards and more.
Why use the Print Size Converter?
Print designs go wrong when a file is set up for screens. A 1080-pixel social graphic prints only about 9 cm wide at 300 DPI, so it looks soft on an A4 flyer. Knowing the pixel dimensions you need before you start — or checking how large an existing image can print well — helps you avoid blurry visiting cards, flyers and banners, and the cost of reprinting them. This converter does the arithmetic at the resolution your printer recommends.
Frequently asked questions
What is DPI?
Dots (or pixels) per inch. It describes how many pixels are printed in each inch of paper; more pixels per inch means finer detail.
Is 72 DPI really "web resolution"?
On screens only the pixel dimensions matter; the DPI value stored in a file does not change how it displays. For print, what matters is the pixel count at the final printed size.
What resolution should a visiting card be?
300 DPI is the usual standard. A 3.5 × 2 inch card needs 1050 × 600 pixels, plus bleed if your printer asks for it.
What is bleed?
Extra image area beyond the trim line — often 3 mm on each side — so no white edges appear after cutting. Ask your printer for their exact requirement.
