How do I find the maximum print size from pixels?

Divide your pixel width by your minimum DPI to get the maximum print width in inches. Divide your pixel height by the same DPI to get the maximum height. For example, a 3000 × 4500 pixel image at 300 DPI can print up to 10 × 15 inches.

What DPI should I use for art prints?

Use 300 DPI for high-quality art prints and photo prints viewed at close range. Use 150 DPI for large wall posters and banners viewed from a distance. Screen-only images can use 72–96 PPI.

Can I print bigger by upscaling my image?

Upscaling adds pixels by interpolation and makes detail soft rather than sharper. For the best result, return to your original source file and increase the canvas resolution before exporting, or reduce the print size to what your current pixel count can support at 300 DPI.

What is the largest size I can print from a 12MP photo?

A 12MP camera typically produces images around 4000 × 3000 pixels. At 300 DPI this supports up to 13.3 × 10 inches. At 150 DPI (suitable for wall art viewed from distance) it supports up to 26.7 × 20 inches.

Maximum print size at 300 DPI

10″ × 15″

25.40 × 38.10 cm

Printing larger than this size at 300 DPI would require upscaling, which reduces sharpness. To print bigger, go back to your source file and increase the canvas resolution.

3600 × 5400	12 × 18 in	24 × 36 in

How to use Maximum Print Size Calculator

Enter your image's pixel width and height, then select your minimum acceptable DPI from the dropdown. The calculator divides your pixel dimensions by that DPI to show the maximum physical size you can print while maintaining the chosen quality level.

Choose 300 DPI for art prints, greeting cards, and any print viewed at arm's length. Choose 150 DPI for large wall posters and exhibition prints where viewers stand at least a metre away — the lower DPI allows a much larger maximum print size from the same file.

If the result is smaller than your intended print, resist the temptation to upscale. Return to your source file — your original Procreate canvas, Photoshop document, or camera RAW — and either export at a higher resolution or accept the smaller maximum print size. A slightly smaller print at native resolution always looks sharper than a larger print produced by resampling.

Frequently asked questions

How does print size relate to DPI?

DPI (dots per inch) describes how many pixels are packed into each inch of a physical print. A 3000-pixel-wide image printed at 300 DPI fills 10 inches of paper (3000 ÷ 300 = 10). Print the same file at 150 DPI and it fills 20 inches. The image does not contain more detail at the larger size — the same pixels are just spread further apart.

What happens if I print below 300 DPI?

At close viewing distances, prints below around 200 DPI start showing visible pixel structure — a grid-like softness or stairstepping on curved edges. The threshold varies by viewer distance: a poster on a far wall looks fine at 100–150 DPI, while a postcard held at reading distance needs 300 DPI to look sharp.

Why should I not upscale to get a bigger print?

Image editors add pixels by interpolation when you upscale — they estimate what colour the new pixels should be based on surrounding pixels. This estimation makes edges softer and fine detail blurrier. The result prints larger but looks worse than the native-resolution file would at a smaller print size.
