Pixel To Real World Calculator
Pixel density from a resolution and a physical size — what the screen is really doing per metre.
Overview
A resolution on its own says nothing about how a surface will read. 3840×2160 across two metres is dense enough to sit behind a presenter; the same resolution across twenty is a stadium wall. Pixels per metre is the number that tells you which you have.
Enter the resolution and the physical size and it gives you density, aspect ratio and area.
When to Use
- Deciding whether content will hold up at the viewing distance
- Comparing two products of different pitch on equal terms
- Checking a proposed wall against content that already exists
Step-by-Step
- Enter the resolution in pixels, width and height.
- Enter the physical size, or load it from Show Elements if the screen is already in the show.
- Read pixels per metre, aspect ratio and physical area.
Tips & Shortcuts
Aspect ratio mismatch is worth checking here. If the pixel aspect and the physical aspect disagree, the panels are non-square and content will stretch unless the map corrects for it.
Density is only half the question — the other half is viewing distance. A low density read from far enough away is fine, which is why stadium walls work.
