You are preparing a photo, illustration, layout, or scan and need to check resolution before exporting or sending it to a print provider.
DPI and Print Size Calculator
Convert pixels, DPI or PPI, and print dimensions, with quick presets for common photo and paper sizes.

Choose pixels to print size when you already have an image, or print size to pixels when planning a file.

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
Calculate pixels needed for a print—or how large an image can print
Enter pixel dimensions and DPI to estimate print size, or apply a common photo or paper size and calculate the pixels required at 150, 200, 300, or 600 DPI.
DPI alone is not a pixel count, and these presets are finished sizes without bleed. Printer, paper, source detail, viewing distance, and provider specifications still matter.

About this tool

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 when you already have an image, or print size to pixels when planning a file.
- Enter dimensions or apply a common finished-size preset.
- Use the print provider's requested DPI/PPI and review the calculated pixels or physical size.
Common use cases
- Check how large a photo can print at 200 or 300 DPI
- Find pixels needed for a 4 × 6 or 8 × 10 print
- Compare the same image at common density values
- Clarify the difference between source-image PPI and printer DPI
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.
| Finished size | At 200 PPI | At 300 PPI |
|---|---|---|
| 4 × 6 in photo | 800 × 1,200 px | 1,200 × 1,800 px |
| 5 × 7 in photo | 1,000 × 1,400 px | 1,500 × 2,100 px |
| 8 × 10 in photo | 1,600 × 2,000 px | 2,400 × 3,000 px |
| US Letter (8.5 × 11 in) | 1,700 × 2,200 px | 2,550 × 3,300 px |
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.
How many pixels is 200 DPI?
DPI alone does not determine a pixel count; you also need the print size. A 4 × 6 inch print at 200 PPI needs 800 × 1,200 pixels.
How many pixels does an 8 × 10 print need at 300 DPI?
It needs at least 2,400 × 3,000 pixels before any bleed or cropping allowance.
Is 300 PPI the same as 300 DPI?
They describe different things: PPI measures image pixels per inch, while DPI measures printer dots. Print instructions often use 300 DPI as shorthand for a 300 PPI source image.
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.
