Quick reference

Print is measured in inches or millimetres, but you design in pixels. Each format below gives the trim size, the pixels at 300 DPI and the bleed printers usually ask for.

From inches and millimetres to pixels

Multiply inches by the resolution to get pixels: a 3.5 × 2 in business card at 300 DPI is 1050 × 600 px. For millimetres, divide by 25.4 first.

Use 300 DPI for anything people hold in their hands, such as cards, flyers and postcards. Large posters seen from a few steps away are fine at 150 DPI.

Trim, bleed and the safe margin

The trim size is the finished size after cutting. Bleed is extra background past that line, usually 0.125 in or 3 mm on each side, so a slightly off cut leaves no white edge.

The safe margin works the other way: keep text and logos a few millimetres inside the trim. Every printer sets its own numbers, so download its template before you design.

FAQ

Questions about these sizes

What DPI should I use for print?

300 DPI for cards, flyers, postcards and small posters that people read up close. 150 DPI is enough for large posters seen from a distance. Screen sizes such as 72 or 96 DPI look soft on paper.

What is bleed in printing?

Bleed is background that runs past the trim line, so the cut never shows a white edge. Most printers ask for 0.125 in or 3 mm on each side, but some want less or more, so check their template.

Can I print a design made for social media?

Only small. A 1080 px wide post is about 3.6 in wide at 300 DPI. For a sharp print, start a new design at the print size in pixels instead of enlarging a screen design.
