How to calculate
Estimate print dimensions from pixel resolution and target PPI.
print size = pixel dimension ÷ target pixels per inch
Worked example
Image width (px): 6000; Image height (px): 4000; Target print resolution (PPI): 300.
Print width: 20 in; Print height: 13.33 in; Megapixels: 24 MP.
Assumptions and limits
This estimates native raster dimensions only. Viewing distance, printer capability, sharpening, resampling, and image quality affect acceptable output.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Estimate print dimensions from pixel resolution and target PPI. The result follows the displayed formula and keeps every adjustable assumption visible.

Frequently asked questions
What can change the image print size result?
This estimates native raster dimensions only. Viewing distance, printer capability, sharpening, resampling, and image quality affect acceptable output.
Should I round the inputs first?
No. Enter the best measurements available and round only the practical final quantity, such as full packs, boards, sheets, or components.
