PIXELS TO INCHES
Print size calculator
Enter a pixel width and height, or upload a photo, then set the DPI. This pixels to print size calculator shows the print size in inches and centimetres, and the maximum size at 150, 300 and 600 DPI. Your image stays in this browser. Nothing is uploaded to a server.
DPI (pixels per inch)
10.0 in × 6.67 in25.4 cm × 16.9 cm · 6.00 MP · 300 pixels per inch
| DPI | Print size | What it means |
|---|---|---|
| 150 | 20.0 in × 13.3 in (50.8 cm × 33.9 cm) | Larger and softer |
| 300 · selected | 10.0 in × 6.67 in (25.4 cm × 16.9 cm) | Practical max for a sharp photo |
| 600 | 5.00 in × 3.33 in (12.7 cm × 8.47 cm) | Finer detail, smaller sheet |
HOW TO
Turn pixels and DPI into a print size.
- 01
Start with pixels or a photo
Type the width and height, or drop in a JPEG, PNG or WebP. An upload fills the pixel fields from the decoded image and, when the file stores a density, suggests that DPI.
- 02
Set pixels per inch
Choose 72, 150, 300 or 600, or type another whole-number DPI from 1 to 1200. For a photo, DPI and pixels per inch are the same unit: one inch of paper gets that many pixels.
- 03
Read inches, centimetres and the max print
Print size is pixels divided by DPI. Compare 150, 300 and 600 DPI to see how large the photo can go before it gets soft. Upscale when you need a bigger sheet without dropping below 300 DPI.
BEFORE YOU RELY ON IT
What the numbers do and do not change.
Pixels to inches for printing
A pixels to print size calculator divides each side by the DPI. 3000 × 2000 pixels at 300 DPI is 10 × 6.67 inches, about 25.4 × 16.9 centimetres. The same photo at 150 DPI prints twice as large and half as sharp, because the same pixels cover more paper.
Pixels per inch calculator
DPI means dots per inch. For a digital photo that is the same idea as pixels per inch, so to convert DPI to pixels per inch you keep the number: 300 DPI is 300 PPI. To calculate DPI from a target print, divide the pixel width by the width in inches. A 3000-pixel side printed at 10 inches is 300 DPI.
Megapixel calculator and max print size
This page also works as a megapixel calculator: width times height, divided by one million. 3000 × 2000 is 6 megapixels. That count does not set the paper size by itself. The practical maximum for a sharp photo print is the size at 300 DPI. 150 DPI is a larger, softer sheet. 600 DPI is for fine detail only when the pixel count already supports a useful page.
When the print would be too small
If the long side is under 1800 pixels or the short side is under 1200, the photo cannot cover a sharp 6 × 4 inch print at 300 DPI. Raising the DPI number makes the print smaller, not clearer. Larger prints without dropping below 300 DPI need more pixels. Upscale the photo with EnhanceWizard, then measure it here again.
GOOD QUESTIONS
Common questions
How does a pixels to print size calculator work?
Divide pixel width by DPI to get inches, and do the same for height. Multiply inches by 2.54 for centimetres. 1800 × 1200 pixels at 300 DPI is 6 × 4 inches, or 15.24 × 10.16 centimetres.
How do I convert pixels to inches for printing?
Choose the DPI your printer or lab expects, usually 300, then divide each pixel side by that number. This page does the division and shows both inches and centimetres.
Are DPI and pixels per inch the same?
For a photo file, yes. To convert DPI to pixels per inch, keep the same number. A pixels per inch calculator and a print size calculator are answering one question: how many image pixels land on each inch of paper.
How do I calculate DPI from a print size?
Divide the pixel width by the print width in inches. A 2400-pixel side on an 8-inch print is 300 DPI. If that result is below 300, the print will look softer unless you add pixels first.
What is the maximum print size of a photo?
At 300 DPI, maximum print size in inches is pixel width divided by 300, and the same for height. The table also shows 150 and 600 DPI so you can compare a larger sheet with a finer one.
Does this megapixel calculator upload my photo?
No. Typed dimensions never leave the page. If you upload an image, it is decoded in your browser only so the pixel size and any stored DPI can be filled in.
