How to convert pixels to inches
- Pick image size to convert a width and height together (the usual case for a photo), or single length for one number such as 1080 px.
- Enter the pixels. For a photo you already have, the numbers are in the file's details: on Windows right-click › Properties › Details, on a Mac open it in Preview › Tools › Show Inspector, on a phone open the photo's info panel.
- Choose the resolution. 300 DPI is the figure photo labs and print shops usually ask for, 150 DPI is enough for posters seen from a distance, and 96 PPI is what a browser or Windows assumes when it shows the image on screen. Pick Custom to type any other value.
- Read the size in inches, the same size in centimetres, and the table showing what the same pixels become at each of the other resolutions.
The converter never changes your file. It only tells you how large the pixels you already have will be at a given density, which is exactly the question "will this print well at 8 × 10?" comes down to.
The formula: inches = pixels ÷ DPI
Inches = pixels ÷ pixels per inch. The pixel count is the number of dots along one side of the image. Pixels per inch (PPI, called DPI by printers) is how tightly those dots are packed when the image is shown or printed. Divide one by the other and you get the physical length.
- 1080 pixels to inches at 300 DPI: 1080 ÷ 300 = 3.6 inches. At 96 PPI the same 1080 px is 11.25 inches, and at 72 PPI it is 15 inches.
- 720 pixels to inches: 720 ÷ 300 = 2.4 inches for print; 720 ÷ 96 = 7.5 inches on a 96 PPI screen.
- 1350 pixels to inches: 1350 ÷ 300 = 4.5 inches; at 96 PPI it is about 14.06 inches.
To get centimetres, multiply the inches by 2.54, because the inch is defined as exactly 2.54 cm. So 1080 px at 300 DPI is 3.6 × 2.54 = 9.144 cm. If you want to start from centimetres, use the pixels to cm converter instead.
Notice that the pixel count never changes. 1080 pixels are 1080 pixels whether they cover 3.6 inches of photo paper or 15 inches of a wall poster. What changes is how much detail each inch gets, which is why a resolution has to be part of the question.
1920 × 1080 pixels in inches
A Full HD frame is the size people ask about most, so here it is at every common resolution:
| Resolution | 1920 × 1080 px in inches | In centimetres |
|---|---|---|
| 72 PPI | 26.667 × 15 in | 67.733 × 38.1 cm |
| 96 PPI (CSS / Windows) | 20 × 11.25 in | 50.8 × 28.575 cm |
| 150 DPI | 12.8 × 7.2 in | 32.512 × 18.288 cm |
| 300 DPI | 6.4 × 3.6 in | 16.256 × 9.144 cm |
| 600 DPI | 3.2 × 1.8 in | 8.128 × 4.572 cm |
So a 1920 × 1080 screenshot or video still makes a sharp print of about 6.4 × 3.6 inches, fits a 5 × 7 inch print at a little under 300 DPI (1920 ÷ 7 = 274 DPI), and would be printed at only 192 DPI on a 10 × 5.6 inch sheet. It is roughly 2 megapixels, which is fine for small prints and too little for an 8 × 10.
Pixels to inches lookup table
The lengths searchers ask for most, worked out at the four resolutions that matter in practice. Inches are rounded to three decimals.
| Pixels | 72 PPI | 96 PPI | 150 DPI | 300 DPI |
|---|---|---|---|---|
| 1 px | 0.0139 in | 0.0104 in | 0.0067 in | 0.0033 in |
| 100 px | 1.389 in | 1.042 in | 0.667 in | 0.333 in |
| 360 px | 5 in | 3.75 in | 2.4 in | 1.2 in |
| 500 px | 6.944 in | 5.208 in | 3.333 in | 1.667 in |
| 600 px | 8.333 in | 6.25 in | 4 in | 2 in |
| 720 px | 10 in | 7.5 in | 4.8 in | 2.4 in |
| 1080 px | 15 in | 11.25 in | 7.2 in | 3.6 in |
| 1200 px | 16.667 in | 12.5 in | 8 in | 4 in |
| 1350 px | 18.75 in | 14.063 in | 9 in | 4.5 in |
| 1500 px | 20.833 in | 15.625 in | 10 in | 5 in |
| 1920 px | 26.667 in | 20 in | 12.8 in | 6.4 in |
| 2400 px | 33.333 in | 25 in | 16 in | 8 in |
| 3000 px | 41.667 in | 31.25 in | 20 in | 10 in |
| 3600 px | 50 in | 37.5 in | 24 in | 12 in |
Read it the other way to plan a print: an 8 inch side needs 2400 px at 300 DPI, a 10 inch side needs 3000 px, and a 12 inch side needs 3600 px. The inches to pixels converter does that direction for any size.
Pixels to inches for printing: common photo sizes
Width × height for the sizes that come out of phones, cameras and social media apps, at print quality (300 DPI) and at screen density (96 PPI):
| Image | Where it comes from | At 300 DPI | At 96 PPI |
|---|---|---|---|
| 1080 × 1080 px | Square social post | 3.6 × 3.6 in | 11.25 × 11.25 in |
| 1080 × 1350 px | 4:5 portrait post | 3.6 × 4.5 in | 11.25 × 14.063 in |
| 1080 × 1920 px | Vertical video, Stories | 3.6 × 6.4 in | 11.25 × 20 in |
| 1200 × 1800 px | Scan of a 4 × 6 print | 4 × 6 in | 12.5 × 18.75 in |
| 1920 × 1080 px | Full HD frame | 6.4 × 3.6 in | 20 × 11.25 in |
| 3000 × 2000 px | 6 MP camera, 3:2 | 10 × 6.667 in | 31.25 × 20.833 in |
| 4032 × 3024 px | 12 MP phone photo, 4:3 | 13.44 × 10.08 in | 42 × 31.5 in |
| 6000 × 4000 px | 24 MP camera, 3:2 | 20 × 13.333 in | 62.5 × 41.667 in |
The 300 DPI column is the largest print that still looks crisp when held in the hand. You can print bigger: the pixels simply spread out and the effective DPI drops. A 4032 × 3024 phone photo printed at 16 × 12 inches runs at 252 DPI, which most people cannot tell from 300. The same photo on a 40 × 30 inch canvas is about 100 DPI, acceptable across a room but soft up close. The DPI calculator gives the effective DPI for any print size, and the print size calculator lists the sizes a photo supports.
If a photo is too small for the print you want, resizing it up adds pixels but no detail. Shooting or exporting at a larger size is the only real fix, though for a quick downsized copy for a shop's upload form our image resizer works in the browser.
How many pixels is 1 inch, and what is 1 pixel in inches?
There is no single answer, which is why every pixels to inches converter asks for a resolution. On the web the answer is fixed by the CSS specification: CSS Values and Units Level 4 defines 1in as exactly 96px, so for anything laid out in CSS, 1 inch is 96 pixels and 1 pixel is 1 ÷ 96 = 0.0104 inches (0.2646 mm). Windows uses the same 96 PPI at 100 % scaling. For printing, 1 inch is however many dots the printer puts down, usually 300 for photos, so 1 pixel is then 0.0033 inches.
A physical screen is different again. A 27 inch monitor showing 2560 × 1440 has about 109 pixels per inch of glass, while a phone can pass 450. The PPI calculator works that out from the diagonal and resolution, and the screen size calculator gives a screen's width and height. Those figures tell you how big an image appears on a particular device; the converter on this page tells you how big it prints.
Why DPI in the file doesn't change the pixel count
Image files can carry a resolution tag (often 72 or 300 DPI). It is only a note to the printer about how to space the pixels. Changing it from 72 to 300 in an editor, with resampling switched off, makes the file print smaller but leaves every pixel in place, so the image quality is untouched. Resampling, on the other hand, really adds or removes pixels. Our guide to what DPI means walks through the difference, and image resolution explained covers pixel dimensions, file size and DPI together.
