See how big you can print from your pixel dimensions.
Updated July 2, 2026Print size = pixels ÷ DPI.
Divide pixel width by the DPI you pick, then divide pixel height by the same DPI. Whatever comes out is the largest size that file can fill at that sharpness, expressed in inches and centimeters.
The fields above start at 6000×4000px. At 300 DPI, the setting most labs use for photo prints, that divides out to 6000 ÷ 300 = 20 in wide and 4000 ÷ 300 = 13.3 in tall. Switch the dropdown to 150 DPI, the setting common for posters, and the same file spreads to 40 × 26.7 in, twice the size in each direction, because the divisor was cut in half.
Drop to 72 DPI, the setting meant for screens rather than paper, and the math allows 83.3 × 55.6 in. Nothing about the file grew; the tool is simply reporting how big you could go if sharpness were not the goal. Move the other direction to 600 DPI, used for archival or gallery-grade output, and the ceiling shrinks back to 10 × 6.7 in from the same 24 megapixels.
Using the 6000×4000px default already loaded above, here is what the four DPI options in the dropdown actually produce:
| DPI setting | Print size | Typical use |
|---|---|---|
| 600 DPI | 10.0 × 6.7 in | Archival scans, gallery prints |
| 300 DPI | 20.0 × 13.3 in | Photo prints, portraits |
| 150 DPI | 40.0 × 26.7 in | Posters, large-format flyers |
| 72 DPI | 83.3 × 55.6 in | Screen display only, not for print |
Every figure above is the same 6000×4000px file divided by each DPI option in the dropdown, nothing looked up elsewhere.
Have a print size in mind already and want to know if a file can hit it? Flip the question with the pixels-you-need calculator. If you have exact pixel counts and a print size and want the DPI they produce, use the DPI checker, or browse the size-and-DPI reference table for common frame dimensions.
Divide pixel width and height by the DPI. At 300 DPI, 6000×4000px prints 20×13.3 inches.
300 DPI for photos, 150 for flyers, 72 for screen only.
Yes, but sharpness drops. Big prints viewed from afar can use 150 DPI.
Width × height in pixels ÷ 1,000,000 - total resolution of the image.
Yes - it determines which frame sizes fit without cropping.
