Pixels to Inches Converter
Convert pixels to inches at any resolution. Check the formula, common photo resolutions, and the print size your file supports at 96, 150, or 300 PPI.
A pixel count on its own does not tell you how big a print will be, so this converter makes the resolution the deciding input rather than an afterthought. Enter pixels and a resolution, and it returns the physical size in inches, plus the metric equivalent. The worked examples cover the resolutions cameras and phone screenshots actually produce.
How it works
The formula
Physical size is the pixel count divided by the resolution, which is the number of pixels the device places in one inch. Everything else is choosing the right resolution for the job, which is why the field is not optional here.
inches = pixels / PPI
Why the same file gives different answers
A phone photo of 4,032 by 3,024 pixels is one file with a fixed amount of detail, but it prints at 13.44 by 10.08 inches at 300 PPI and at 42 by 31.5 inches at 96 PPI. The second number is not extra detail, it is the same detail spread over more paper. That is the distinction that decides whether a print looks sharp or soft, and it is why a resolution is never an optional field.
NoteEnlarging a print never adds detail. The pixel count sets a ceiling on how large the image can be before it visibly softens.
Worked examples from real resolutions
These are the pixel dimensions that cameras and phones actually produce. The columns show the physical size at each common resolution, so you can pick the column that matches the print you want.
| Pixel count | At 96 PPI | At 150 PPI | At 300 PPI |
|---|---|---|---|
| 600 px | 6.25 in | 4.00 in | 2.00 in |
| 1,080 px | 11.25 in | 7.20 in | 3.60 in |
| 1,920 px | 20.00 in | 12.80 in | 6.40 in |
| 3,000 px | 31.25 in | 20.00 in | 10.00 in |
| 3,024 px | 31.50 in | 20.16 in | 10.08 in |
| 4,000 px | 41.67 in | 26.67 in | 13.33 in |
| 4,032 px | 42.00 in | 26.88 in | 13.44 in |
| 6,000 px | 62.50 in | 40.00 in | 20.00 in |
Which resolution to use
Match the resolution to how the image will be seen. A print held in the hand needs the pixels to be dense, so 300 PPI. A poster across a room does not, so 150 PPI is enough and lets you print twice as large. Screen images have no physical size at all until you choose one, and CSS treats 96 PPI as the reference so that layout is predictable.
- 300 PPI for photographs printed at close range, including most lab prints and A4 pages.
- 150 to 200 PPI for posters, banners, and wall prints viewed from a distance.
- 96 PPI for anything measured in CSS, since that is the reference browsers assume.
- 72 PPI for web images and email, where the display resolution replaces any real measurement.
Converting both dimensions at once
Print size only means something as a pair. A 1,920 by 1,080 image at 300 PPI is 6.4 by 3.6 inches, which is a 16 by 9 shape rather than any standard paper size. If you need a specific paper size, work from the target dimensions instead: check the print size calculator for the maximum, or resize to a print preset such as 4 by 6.
Frequently asked questions
How do I convert pixels to inches?
Divide the pixel count by the resolution. At 300 PPI, 1,200 pixels is 4 inches. At 96 PPI, the same 1,200 pixels is 12.5 inches, which is why the resolution matters more than the pixel count.
How many inches is 1080 pixels?
It depends on the resolution. At 300 PPI, 1,080 pixels is 3.6 inches. At 150 PPI it is 7.2 inches. At 96 PPI it is 11.25 inches. Enter the resolution that matches your use to get the real answer.
Is there a fixed number of pixels per inch?
For printing, use the target resolution, usually 300 PPI for close up prints and 150 PPI for large posters. For screens, CSS defines 96 PPI as a reference, so 1 inch of CSS is 96 pixels regardless of the screen in front of you.
What resolution do I need for a sharp print?
300 PPI for photographs viewed close up, 150 to 200 PPI for posters and banners seen from a distance, and about 72 PPI for images that only appear on screen. Use the print size calculator to work out the largest size your file supports.
Does converting pixels to inches change my file?
No. It is a calculation about a print, not a resize. If you want a new image file at a different physical size, use the print resizer or the resizer presets instead.
