Pixel pitch guide: P3.9 vs P2.5 vs P1.5

Rule of thumb: allow about 3.3 ft of viewing distance per millimeter of pixel pitch. P3.9 looks sharp from about 13 ft, P2.5 from about 8 ft, P1.5 from about 5 ft.

Pixel pitch is the distance in millimeters between the centers of two LED pixels. A smaller number means pixels are closer together, the image looks smoother up close, and the wall costs more.

The 3.3 ft rule

Multiply the pitch in millimeters by 3.3 to get the closest comfortable viewing distance in feet. Viewers closer than that start to see individual pixels; viewers farther away see a smooth image.

Pitch	Closest comfortable viewing	Typical use	CatMotion price per sq ft
P0.9	~3 ft	Boardrooms, broadcast, premium venues	—
P1.5	~5 ft	Home cinema, boardrooms	$198–$239
P1.86	~6 ft	Broadcast, close viewing	$140–$190
P2.5	~8 ft	Stages, conference rooms, chapels	$133–$140
P2.6 outdoor	~9 ft	Premium outdoor, rental	$144–$147
P3.9	~13 ft	Churches, events, retail, outdoor	$95–$104 indoor

Viewing distances are a rule of thumb (about 3.3 ft per mm). Prices are complete-package prices; P0.9 is quoted per project.

Resolution: what you actually get

Resolution depends on both pitch and size. The same pitch on a bigger wall gives more pixels. Examples from our packages:

P3.9 Indoor, 8.2 × 5.0 ft: 640 × 384 px
P2.5 Indoor, 8.4 × 4.7 ft: 1,024 × 576 px
P3.9 Outdoor, 11.5 × 6.6 ft: 896 × 512 px
P2.6 Outdoor, 9.8 × 6.6 ft: 1,152 × 768 px
P1.86 Indoor, 10.5 × 6.3 ft: 1,720 × 1,032 px
P1.5 Indoor, 12.6 × 6.3 ft: 2,560 × 1,280 px
P0.9 COB 4K, 11.8 × 6.6 ft: 4,002 × 2,250 px

Full 4K (3,840 px wide or more) needs either a very fine pitch or a very large wall. Our P0.9 COB 4K package reaches 4,002 × 2,250 px at 11.8 × 6.6 ft.

How to choose in three steps

Measure the distance from the wall to the closest seat or viewer.
Divide by 3.3 to get the largest pitch that will look sharp from there.
Pick that pitch or the next finer one if close-up camera shots or small text matter. Going finer than needed mostly adds cost.

Quick answers

What pixel pitch do I need for a church?

If your front row is about 13 ft or more from the stage, P3.9 is usually enough; closer seating or heavy camera use suits P2.5.

Is P2.5 better than P3.9?

P2.5 looks smoother from closer (about 8 ft versus about 13 ft) but costs more: about $133–$140 per sq ft versus $95–$104 at CatMotion. From far away, viewers will not see a difference.
