Printing Size Calculator
Calculate maximum print size from your image resolution, or find out how many pixels you need for a specific print size. Ensure sharp, professional-quality prints every time.
Printing Size Calculator
Calculate maximum print size from image resolution or required pixels for a print size
DPI Guidelines:
- • 300 DPI: Professional prints, close viewing
- • 240 DPI: High quality home prints
- • 150 DPI: Large prints viewed from distance
- • 72 DPI: Screen display only
Formula
Print Size = Pixels ÷ DPIHigher DPI means sharper prints but smaller maximum size

Frequently Asked Questions
What DPI should I use for printing?
300 DPI is the standard for professional prints viewed up close. 240 DPI is acceptable for most home prints. For large prints viewed from a distance (posters, banners), 150 DPI or even lower can work well.
How many megapixels do I need for a large print?
For a 16×20" print at 300 DPI, you need about 29 megapixels. For 8×10" at 300 DPI, you need about 7.2 megapixels. Most modern cameras (24+ MP) can produce excellent prints up to 16×20".
Can I print larger than the calculator suggests?
Yes, but quality will decrease. Large prints are often viewed from farther away, so lower DPI is less noticeable. A billboard might only be 15 DPI but looks fine from across the street.
What is the difference between DPI and PPI?
PPI (pixels per inch) refers to digital images, while DPI (dots per inch) refers to printed output. They're often used interchangeably, but technically DPI depends on your printer's capabilities.
Why do my prints look different from my screen?
Screens emit light while prints reflect it, causing color differences. Calibrate your monitor and use soft-proofing in your editing software. Also ensure your print lab uses color profiles.
