Free print preparation tools
Three calculations that answer most print-resolution questions before a file is ever sent anywhere. Everything below runs in your browser: nothing is uploaded, nothing is stored, no account is needed.
These tools take numbers, not files. Your inputs never leave the page.
Image DPI checker
Enter your pixel dimensions and the size you mean to print. See horizontal, vertical and limiting DPI, and which edge thins out first.
- Answers
- At the size I want, is there enough detail?
- You provide
- Pixel width and height, plus the print size you intend
- You get
- Horizontal, vertical and limiting DPI, and which edge is the tight one
Pixels to print size
Enter the pixel dimensions of your image and see the print size it produces at three common resolution targets, in inches and centimetres, side by side.
- Answers
- With these pixels, how large does the print come out?
- You provide
- Only the pixel width and height of your image
- You get
- Print size at 300, 200 and 150 DPI, in inches and centimetres
Print size calculator
Enter a pixel width and the width you want to print. See the effective resolution and the width the file covers at full detail.
- Answers
- How wide can this go, and what happens at the width I picked?
- You provide
- Pixel width, and the print width you are aiming for
- You get
- Effective DPI at that width, plus the width covered at full detail
When numbers are not enough
A calculator can tell you how much detail a file has. It cannot tell you whether the edges are clean, whether the transparency is real, or whether a logo was saved from a chat app and quietly softened. That is what the SafeWidth engine measures on the file itself.
