Print resolution (DPI) check
Choose an image or enter its pixel size; see whether the resolution is enough for the print size and viewing distance.
Quick start
Choose the image
Shown under “image size” in your editor; enter the pixel count, not the DPI tag.
The file is not uploaded; only its pixel size is read in your browser. PNG, JPG, WebP, GIF, AVIF. For PDF, TIFF and PSD, enter the pixel size in the pixel fields.
Enter the print size and distance
Width × height in cm; for example 300 × 100 or 3 m × 1 m.
The closest distance from viewer to print, in metres; for example 3 (0.1–500 m).
Advanced settingsPrint type: Banner

Formula: effective DPI = pixels ÷ print size (in); sharpness limit = 3438 ÷ distance (in), pixels invisible = 6878 ÷ distance (in). Sources: Northlight Images, print-size.utils.com. Thresholds are a proposal.

Frequently asked questions
What DPI does a banner need?
72–100 DPI at print size is enough for most facade banners. From 10 m the eye resolves about 9 dots per inch, so even a 50 DPI file looks sharp at that distance. If pedestrians look closely or there is small text, aim for 100–150 DPI.
Is 300 DPI necessary?
No. 300 DPI is for magazines and brochures read in hand. In large format, the required resolution falls as viewing distance grows: about 30–60 DPI at 3 m and 9–17 DPI at 10 m are enough. More only makes the file bigger without a visible difference.
My file says 72 DPI. Will the print be bad?
The DPI tag alone says nothing. What matters is the pixel count: a 6000-pixel image gives 51 DPI at 3 m wide and 152 DPI at 1 m wide. That is why the tool uses the pixel size, not the tag.
What if my image is not good enough?
Ask for a larger source file, reduce the print size, or enlarge the image 2–4× with AI upscaling. For text, logos and line art, a vector file (PDF, AI, SVG) stays sharp at any size.
Is my file uploaded to a server?
No. The file opens in your browser, only its pixel size is read and the calculation runs on your device. For files the browser cannot open, such as PDF, TIFF and PSD, enter the pixel size manually.
