Convert between pixels, inches, and centimeters at any DPI — enter one, get the other two.
Conversion depends on DPI (dots per inch): pixels = inches × DPI, and 1 inch = 2.54 cm. Print uses 300 DPI; screens are often 72–96 DPI.
The same pixel count prints big and sharp or small and soft depending on DPI. Convert with the right number and size prints correctly.
Pixels, inches, or centimeters — enter any one and get the other two instantly at your chosen DPI.
Know exactly how big your pixels print. Essential for listing the right dimensions on Etsy at 300 DPI.
Get both inches and centimeters, so you can serve US and international buyers without second-guessing.
No signup, no limits. Convert as often as you like.
Everything you need to size a file for print: the formula, reference tables in both directions, which DPI to pick, and what to do when your image is too small.
Pixels have no physical size on their own. A 3000-pixel-wide image is 10 inches wide at 300 DPI, 20 inches at 150 DPI, and 41.7 inches at 72 DPI — same file, three different prints. DPI (dots per inch) is what ties a pixel count to a real-world measurement, which is why every conversion needs it.
Divide the pixel count by the DPI. 3000 px ÷ 300 DPI = 10 inches.
Multiply the inches by the DPI. 10 inches × 300 DPI = 3000 px.
Convert to inches first, then multiply by 2.54. 3000 px ÷ 300 DPI = 10 inches × 2.54 = 25.4 cm.
DPI and PPI are the same number here
Strictly speaking PPI (pixels per inch) describes a digital image and DPI (dots per inch) describes what a printer lays down. Every print shop and marketplace uses them interchangeably, and for sizing your file they give the same answer. Don't lose time on the distinction.
300 DPI is the print standard, so these are the numbers you need most often. If your image is one of the common AI output sizes, this table tells you immediately how big it can print.
| Pixels | Inches | Centimeters |
|---|---|---|
| 1024 px | 3.41" | 8.7 cm |
| 1536 px | 5.12" | 13.0 cm |
| 2048 px | 6.83" | 17.3 cm |
| 3000 px | 10.00" | 25.4 cm |
| 4096 px | 13.65" | 34.7 cm |
| 6000 px | 20.00" | 50.8 cm |
The first row is the one that catches sellers out. Most AI image generators output 1024×1024 by default, and at 300 DPI that prints just 3.4 inches square — smaller than a postcard. It is not a print-ready file for wall art no matter how good it looks on screen.
Working the other direction is what you actually do before listing. Pick the frame size you want to sell, and this is the pixel dimension your file has to hit at 300 DPI.
| Print size | Pixels at 300 DPI | Metric |
|---|---|---|
| 4×6" | 1200 × 1800 | 10.2 × 15.2 cm |
| 5×7" | 1500 × 2100 | 12.7 × 17.8 cm |
| 8×10" | 2400 × 3000 | 20.3 × 25.4 cm |
| 11×14" | 3300 × 4200 | 27.9 × 35.6 cm |
| 16×20" | 4800 × 6000 | 40.6 × 50.8 cm |
| 18×24" | 5400 × 7200 | 45.7 × 61.0 cm |
| 24×36" | 7200 × 10800 | 61.0 × 91.4 cm |
| A4 | 2481 × 3507 | 21.0 × 29.7 cm |
| A3 | 3507 × 4962 | 29.7 × 42.0 cm |
| A2 | 4962 × 7017 | 42.0 × 59.4 cm |
A4 at other resolutions comes up often too: 1240 × 1754 px at 150 DPI, and 595 × 842 px at 72 DPI. Only the 300 DPI figure is safe to sell as a print file.
| DPI | Use it for | Notes |
|---|---|---|
| 300 | Print-ready files, Etsy digital downloads | The default. Sharp at arm's length. |
| 150–299 | Large pieces viewed from a distance | Fine for a 24×36" poster, visibly soft up close. |
| 72–96 | Screen graphics, mockups, web previews | Never sell this as a print file. |
Higher than 300 DPI rarely helps. Printers cannot resolve the extra detail at normal viewing distance, and the file size climbs fast. 600 DPI is worth it only for fine line art and text-heavy designs.
If the numbers say your image cannot fill the size you want to sell, you have three options — and only two of them are honest.
If you are not sure whether a file you already have is print-ready, check it against every standard frame size.
Everything you need to know about this free tool.
Divide pixels by DPI. At 300 DPI, 3000 pixels ÷ 300 = 10 inches. Enter your value and DPI above and the tool converts to inches and centimeters automatically.
It depends on DPI. At 300 DPI (print standard) one inch is 300 pixels; at 96 DPI (typical screen) it's 96 pixels. Set the DPI to match your use.
Use 300 DPI for print-ready art and physical prints. For screen-only graphics, 72–96 DPI is typical. This converter lets you set whichever you need.
Convert pixels to inches (pixels ÷ DPI), then multiply by 2.54. The tool shows centimeters alongside inches automatically.
