Image & Print Size
Pixels to Inches Calculator
Convert image pixels to print inches, mm and cm at any DPI.
How it works
Inches = pixels ÷ DPI on each axis.If the resulting inches are smaller than the ordered print size, the file is under-resolved for that job.
Worked example
A DTF design is 3600 px wide.Target DPI: 300.
Print width = 3600 ÷ 300 = 12 inches (304.8 mm).
Common DPI targets
| Use case | Typical DPI | Notes |
|---|---|---|
| Apparel / DTF close view | 300 | Best default for shirts and transfers |
| Large format poster | 100–150 | Viewed from farther away |
| Billboard / banner | 30–72 | Distance viewing only |
Frequently asked questions
Is DPI the same as PPI?
For this calculator, yes. Both describe pixels per inch of the printed size.
What DPI should I use for DTF?
Most shops aim for 300 DPI artwork. Confirm with your RIP software and printer profile.
What DPI should I enter?
Use the DPI you will print at (often 300 for apparel/DTF). Do not invent a higher DPI to “make inches look good.”
Why do width and height inches disagree with the mockup?
Usually the mockup is stretched or the file was cropped. Measure the real pixel box for the art that will print.
Can I mix units with centimetres?
Convert cm to inches first with the CM converter, then build or check pixels.
