Breakdown
DPI Quality Reference
≥ 300 DPI — Photographic quality, fine detail
150–299 DPI — Acceptable for posters viewed from arm's length
100–149 DPI — Large-format banners viewed from a distance
< 100 DPI — Pixelation likely at close viewing distance
Summary
Calculate DPI for a given print size, or find the maximum print size achievable at a target DPI from your pixel dimensions.
How it works
- Enter the image width and height in pixels.
- Choose a mode: "Calculate DPI" or "Find Max Print Size".
- In DPI mode, enter the desired print width and height in inches to see the resulting DPI.
- In Max Size mode, enter your target DPI to see the largest print your image can produce at that quality.
- Results update instantly as you type.
Use cases
- Verify a photo will print at 300 DPI before sending to a print lab.
- Find out how large you can blow up an image without visible pixelation.
- Check whether a client-supplied image meets minimum print resolution requirements.
- Plan camera megapixel requirements for large-format prints.
