Image & Print Size
Image Print Size Calculator
See full print width and height in inches from pixel dimensions and DPI.
You get physical size in inches and millimetres, megapixels, aspect ratio, and the largest sharp size at 300 DPI for close viewing.
How it works
Each side: inches = pixels ÷ DPI.Aspect ratio compares width to height so you know if the art matches a garment template.
Worked example
4500 × 5400 px at 300 DPI prints as 15 × 18 inches — a common full-front DTF size on adult mediums.When resolution is enough
| Viewing distance | Minimum DPI feel | Action |
|---|---|---|
| Handheld / shirt | 300 | Enlarge art or reduce print size if below |
| Poster on wall | 150 | Often acceptable at 2–3 ft |
| Banner / tent | 72–100 | Design for distance, not close inspection |
