Print Size Calculator
Can you print that photo at 8×10? Pixels → max print size and quality per size.
Updated July 8, 2026
How to use the print size calculator
- 1Enter your image's pixel dimensions (check file properties or the EXIF viewer).
- 2Pick the DPI standard for how it'll be viewed — 300 in-hand, 150 posters.
- 3Read the maximum print size and the quality verdict per standard size.
- 4Order the largest size still marked good — or step down one for gallery-grade.
Common uses
- Checking a phone photo before ordering canvas or framed prints
- Sizing images correctly for Etsy printables and print-on-demand products
- Working out required resolution before a shoot meant for large prints
- Explaining to a client why their 800px logo can't go on a banner
Frequently asked questions
What DPI do I actually need?
It's about viewing distance: 300 DPI for prints examined in hand (photo books, 4×6s), 200–240 for framed prints on a wall, 150 for posters, and billboards run under 30 because nobody reads them from arm's length. The per-size table applies these thresholds for you.
Can I just upscale my image to add resolution?
Upscaling adds pixels, not detail — traditional resampling makes a bigger soft image. Modern AI upscalers genuinely help within limits (2× is usually credible, 4× is gambling), but a photo that's sharp at its native size printed slightly smaller beats an upscaled version printed larger.
How many megapixels for common prints?
At 300 DPI: a 4×6 needs just 2.2 MP, an 8×10 needs 7.2 MP, an 11×14 about 14 MP. At poster distances (150 DPI), a 12 MP phone photo covers 16×20 comfortably — resolution is rarely the limiting factor people assume; focus and noise usually are.
Do DPI and PPI mean the same thing?
Colloquially yes; technically PPI is image pixels per printed inch and DPI is the printer's ink dots (printers lay many dots per pixel). Print services say DPI and mean PPI. This calculator follows the colloquial usage, which is what your print order form means.
About this tool
The print size calculator answers the question every photo print order raises: is this image sharp enough? Enter pixel dimensions and a target DPI to get the maximum print size in inches and centimeters — and, more usefully, a quality verdict for every standard print size from 4×6 to 24×36, computed from the effective DPI your pixels deliver at each size. The bands reflect how prints are actually viewed: 300 DPI is the in-hand standard, 150 is fine for posters seen from a few feet, and big wall art tolerates less than spec sheets admit. Includes the number people never believe: a modern phone's 12 MP prints an excellent 10×13.
