Print Viewing-distance Calculator
Estimate a practical print-resolution range from expected viewing distance.
What this tool does
A visual-acuity approximation converts viewing distance into a directional pixels-per-inch target.
Estimate a practical print-resolution range from expected viewing distance.
A visual-acuity approximation converts viewing distance into a directional pixels-per-inch target.
Use the tool
Relate viewing distance to resolution
Enter the nearest expected viewing distance.

Visual-acuity planning estimate
- Conservative range
- 22–36 PPI
- Viewing distance
- 3 m
Use the closest expected viewer and confirm with a physical proof.
How to use it
Three quick steps
- 1Enter the nearest expected viewing distance.
- 2Use the estimated PPI as a planning range, not a print guarantee.
- 3Verify the result in its real production context. Eyesight, content detail, lighting, substrate, print process, and client expectations affect the real requirement.
Worked example
Example: Viewing-distance Calculator
