Pixels to print size
You have an image and no idea how large it can go. This converts the pixel dimensions straight into print size at three common targets at once, so the comparison itself answers the question — no need to guess which resolution to ask for first.
Enter your pixel dimensions to see how large the file goes.
| Answers | With these pixels, how large does the print come out? |
|---|---|
| You provide | Only the pixel width and height of your image |
| You get | Print size at 300, 200 and 150 DPI, in inches and centimetres |
| Direction | Pixels in, size out — the reverse of the DPI checker |
| Both units | Every row shown in inches and centimetres, no conversion needed |
| Runs | A division done on the page itself — nothing leaves your device |
Why three numbers instead of one
A single answer forces a decision you have not been given the information to make. Seeing 300, 200 and 150 together turns the question into something you can judge: the gap between the rows is exactly what you are trading when you print larger, and the right row depends on how close the print will be looked at.
Finding your pixel dimensions
Every operating system shows them without any extra software, and no file needs to leave your computer to find out.
- macOS: select the file and press space, or open Get Info and read the Dimensions line
- Windows: right-click, Properties, then the Details tab
- Phones: the photo's info panel lists the dimensions, usually beside the file size
- Any browser: open the image in a tab and the title bar reports its pixel size
The rows are targets, not limits
Nothing stops a file from being printed larger than its 150 DPI row. The table describes what the detail supports, and printing past it is a choice with a visible cost rather than an error. What the rows are good for is the opposite direction: they tell you quickly whether the size you had in mind was ever realistic.
FAQ
- Which row should I use for a t-shirt?
- Garment work is usually judged from a distance, so the 200 DPI row is a reasonable working answer and the 150 row is often acceptable for large, simple artwork. The 300 row is the safe choice for small detailed pieces such as a left-chest logo.
- My image is 4000 × 3000. Is that good?
- It depends entirely on the size you want. That file is about 13 × 10 inches at 300 DPI and about 27 × 20 inches at 150 — good for a poster, generous for a shirt, thin for a wall-sized banner viewed up close.
- Why does this not ask for the DPI stored in the file?
- Because that number does not describe the pixels. It is a tag that travels with the file and is frequently wrong, while the pixel dimensions are the detail that actually exists.
- Is this the same as the DPI checker?
- It is the same arithmetic run the other way. Use this when you know your pixels and want the size; use the DPI checker when you know the size and want to know whether the detail holds.
