IMAGE RESOLUTION CHECKER

DPI Checker for Printing

Upload an image and enter the size you want to print. WAT calculates the effective PPI from the real pixel dimensions instead of trusting a metadata number.

What does a DPI checker actually need to check?

For a digital image, pixel dimensions are more useful than a metadata label such as 72, 96 or 300 DPI. Effective print resolution is calculated from the image pixels and the physical size you plan to print.

effective PPI = image pixels ÷ print inches

Wall Art Toolkit reports the limiting axis, because both width and height must contain enough pixels for the requested print size.

How to interpret the result

300+ PPIStrong reference for detailed close viewing.
240–299 PPIHigh-quality range for many prints.
200–239 PPIOften useful for wall art.
150–199 PPICan work for larger pieces viewed farther away.

These are practical reference ranges, not universal pass/fail rules. Printer, paper, artwork type and viewing distance matter.

DPI checker FAQ

How do I tell the DPI of an image?

Metadata can contain a DPI/PPI tag, but it does not tell you whether the file has enough pixels for a specific print. For print quality, calculate effective PPI at the intended dimensions.

Does changing 72 DPI to 300 DPI improve an image?

Not by itself. Changing only metadata does not add image detail. More source pixels or careful resampling are required to change pixel dimensions.

How do I check image DPI for a 24×36 print?

Enter 24×36 inches as the target. A 7200×10800 image gives 300 PPI; 4800×7200 gives 200 PPI.
