PPI describes image pixels per inch; DPI originally describes printer dots per inch. Print workflows often use “300 DPI” as shorthand for a 300 PPI source image.
Quick answer
Convert pixels, DPI, and physical print size
Enter pixel dimensions and DPI to estimate print size, or enter a target print size and DPI to calculate the pixel dimensions you need.
DPI math predicts pixel density, not printer quality; viewing distance, paper, sharpening, and the print process also affect the result.

About this tool
Convert pixels, DPI or PPI, and print dimensions in inches or centimeters for photos, artwork, and layouts.
Typed values and optional image dimensions are processed locally in your browser and are not uploaded to a server.
Reminder
DPI and PPI are used here as planning inputs for pixel density. Actual print quality also depends on viewing distance, source sharpness, printer, paper, resampling, and the print provider's workflow.
How to use it
- Choose pixels to print size or print size to pixels.
- Enter the pixel dimensions or desired print dimensions and select inches or centimeters.
- Choose a DPI value and review the calculated dimensions.
Common use cases
- Check how large a photo can print at 300 DPI
- Find pixels needed for an 8 × 10 inch print
- Compare 150, 240, and 300 DPI output
- Read image dimensions before preparing artwork
Pixels, DPI, PPI, and Print Size
For this planning calculation, print width in inches equals pixel width divided by the selected pixels-per-inch value. The interface uses the familiar DPI label even though PPI more precisely describes image pixels.
| Image | At 300 DPI | At 150 DPI |
|---|---|---|
| 3000 × 2400 px | 10 × 8 in | 20 × 16 in |
| 2400 × 3000 px | 8 × 10 in | 16 × 20 in |
| 1800 × 1200 px | 6 × 4 in | 12 × 8 in |
Choose a Resolution for the Viewing Distance
A higher pixel density can preserve fine detail at close viewing distance, while a large poster viewed from farther away may not need the same density. Ask the print provider for its file specifications before exporting final artwork.
- 300 DPI is a common close-viewed print target, not a universal guarantee.
- Cropping changes both the aspect ratio and the pixels available for printing.
- Changing only the DPI metadata does not add captured detail.
FAQ
What is the print-size formula?
Print width in inches equals pixel width divided by DPI. For centimeters, multiply the inch result by 2.54.
Is 300 DPI always required?
No. It is a common target for close-viewed prints, but larger prints viewed from farther away may look acceptable at a lower density.
Does changing DPI add image detail?
No. Changing a DPI metadata value alone does not create new source detail. Resampling can add pixels, but it cannot recover detail that was never captured.
Can the tool read my image dimensions?
Yes. You can select an image to fill its pixel width and height locally.
