Pitch is the distance between pixels. Closer viewers need a finer pitch. This note is the rule of thumb we use before a formal drawing.

Measure the nearest seat, not the far wall. A lobby where people walk up to the screen is a close-view job even if the room is large.
| Nearest viewer | Start at |
|---|---|
| Under 3 m | P1.2–P1.8 |
| 3–6 m | P1.9–P2.9 |
| Over 6 m | P3.9 or coarser |
