Pixel Pitch vs. Screen Size: How They Work Together

When shopping for an LED sign, two terms often get mixed up: pixel pitch and screen size. They’re related, but not the same—and understanding the difference can save you money while ensuring your message looks its best.

What Is Pixel Pitch?

Pixel pitch refers to the distance (in millimeters) between the center of one LED “bulb” and the next. A smaller number means the LEDs are closer together, creating higher resolution and sharper detail.

• P10: 10 mm spacing

• P8: 8 mm spacing

• P6: 6 mm spacing

What Is Screen Size?

Screen size is simply the physical dimensions of your LED display. It determines how big your messages appear, but not necessarily how clear they look.

Why It Matters Together

A large P10 sign (for a highway billboard) can look just as sharp to drivers at 200 feet as a smaller P6 sign outside a retail store viewed at 20 feet. Resolution only matters when paired with viewing distance.

Key takeaway: Bigger doesn’t always mean clearer—match screen size with pixel pitch and where your audience will be.
