hobby.photography-print-size Calculator
Calculates the maximum print size at 300 DPI and 150 DPI from camera resolution, and compares it to standard photo paper sizes. Tells photographers exactly how large they can print before losing sharpness.
Inputs
Megapixels
Reference formula or conversion factor shown for context.
Print Dpi
Reference formula or conversion factor shown for context.
Aspect Ratio W
Horizontal extent perpendicular to the length.
Aspect Ratio H
Vertical measurement. For health calculators, typically standing height without shoes.
Results
max print width (inches)
The computed width.
max print height (inches)
The computed height.
max print (cm)
Sample size or count used in the calculation.
pixel dimensions (approx)
Sample size or count used in the calculation.
at 150 DPI (poster quality)
A qualitative assessment of how the result compares to the desired standard or benchmark.
300 DPI = photo lab quality
A qualitative assessment of how the result compares to the desired standard or benchmark.
