How to Calculate Print Size
Pixels ÷ DPI = Inches
Divide each pixel dimension by the print resolution to get the matching paper dimension in inches.
At 300 DPI
A 3000 × 2000 px photo prints about 10 × 6.7 inches at 300 DPI.
At 150 DPI
The same 3000 × 2000 px photo prints about 20 × 13.3 inches at 150 DPI, often suitable for posters viewed from farther away.

Print Size Calculator — Common Questions
How do I calculate print size from pixels?
Divide the image width and height in pixels by the print DPI. For example, 3000 × 2000 px at 300 DPI prints about 10 × 6.7 inches.
How large can I print a 3000 × 2000 pixel photo?
At 300 DPI it prints about 10 × 6.7 inches; at 150 DPI it prints about 20 × 13.3 inches. The lower resolution is often suitable for a poster viewed from farther away.
How many pixels does an 8 × 10 inch print need at 300 DPI?
It needs 2400 × 3000 pixels: 8 × 300 for one side and 10 × 300 for the other.
Can I print a poster at 150 DPI?
Often, yes. A poster viewed from a few feet away can look good at 150 DPI, which needs half as many pixels on each side as 300 DPI. Check your print shop’s recommended resolution for the size and viewing distance.
Will changing the DPI number make my photo sharper?
No. Changing DPI metadata does not add pixels or detail. Learn what 300 DPI means and how to prepare enough pixels on our 300 DPI guide.
What can I do if my image does not have enough pixels?
Use AI upscaling to add pixels. PicUpscaler includes 2x upscaling free each day, 4x with Pro, and 8x with Premium. See plans and pricing.
