Pixels per inch for print
Aim for 300 PPI for detailed prints viewed up close; 240 PPI is often very good, 150–200 PPI can suit larger prints, and lower values need more viewing distance.
Calculate effective PPIPPI tells you how many image pixels are available for each inch of the final print. It is calculated from the real pixel dimensions and physical output size.
The best target depends on viewing distance, image detail, paper, and printer. Treat the ranges as practical guidance rather than a substitute for a proof.
Use a practical PPI target
Use 300 PPI for photo books, portfolios, small artwork, and prints inspected closely. It preserves fine texture and small details.
A well-prepared image around 240 PPI can still look excellent. Avoid unnecessary upscaling when the original is already close to the needed density.
- 300 PPI: detailed, close-viewed print
- 240 PPI: very good for many photo prints
- 150–200 PPI: larger prints or longer viewing distance
- Below 150 PPI: proof carefully before production
Calculate effective PPI
Divide the image width in pixels by the printed width in inches, then repeat for height. The lower result is the effective PPI.
Cropping removes pixels, so calculate again after choosing the final crop rather than relying on the uncropped file dimensions.
Judge the result in context
Sharpness also depends on focus, motion blur, compression, sharpening, and the print process. A 300 PPI file cannot repair a blurry source.
For expensive or colour-critical output, inspect the image at 100% and order a physical proof at the intended scale.

Frequently asked questions
How many pixels per inch should I use for printing?
300 PPI is a common target for detailed close-viewed printing. Larger prints can often use 150–240 PPI depending on viewing distance.
Is 240 PPI good for printing?
Yes. 240 PPI is often enough for a very good photographic print when the source image is sharp.
Does increasing the DPI label improve quality?
No. Changing metadata does not add pixels; effective PPI depends on actual pixels divided by final print inches.
