Photo Print Size Calculator – How Large Can I Print My Photo?

How large can I print my photo?

The maximum print size depends on two factors: the number of pixels in your image and the DPI you want to print at. The formula is:

        Max Print Width = Pixel Width ÷ DPI

        Max Print Height = Pixel Height ÷ DPI

Example: A 4000×3000 pixel photo:

At 300 DPI → prints at 13.3″ × 10″ (professional quality)
At 200 DPI → prints at 20″ × 15″ (good for framed prints)
At 150 DPI → prints at 26.7″ × 20″ (acceptable for large prints)
At 72 DPI → prints at 55.6″ × 41.7″ (blurry, screen quality only)

Upload your image to the DPI Checker to see all these values instantly, plus a compatibility check for 7 standard paper sizes.

Frequently Asked Questions

How do I calculate print size from pixels?

Divide the pixel dimension by the DPI. For a 3000-pixel-wide image at 300 DPI: 3000 ÷ 300 = 10 inches wide. The DPI Checker does this automatically and also converts to centimetres (multiply by 2.54).

What DPI should I use for printing at a photo lab?

Most professional photo labs (including online services like Shutterfly, Snapfish, and Photobox) require 300 DPI at the desired print size. Some accept 200 DPI for larger prints viewed at distance. Check your lab's specific guidelines and use the Custom DPI Calculator to verify your image meets requirements.

Can I increase my photo resolution to print larger?

Standard upscaling (just adding pixels via interpolation) degrades quality. However, AI-powered upscaling can genuinely increase pixel count with detail restoration. Try our AI Image Upscaler to increase resolution before large prints.
