Pixel Pitch vs. Resolution: What Do They Mean for Outdoor LED Signs?

What Is Pixel Pitch in an Outdoor LED Sign?

Pixel pitch is the distance, in millimeters, between the centers of two pixels on an LED display. Smaller pixel pitch creates sharper, more detailed images for close viewing, while larger pixel pitch works best for signs viewed from farther away.

Examples of Outdoor Pixel Pitch:

• 6mm-10mm: Best for street-level signs where viewers are nearby.
• 16mm-20mm: Best for highway billboards and large roadside displays where viewers are far away and moving quickly.

What Is Resolution in an Outdoor LED Sign?

Resolution is the total number of pixels on a sign, measured horizontally and vertically. Higher resolution produces sharper images and clearer text, while moderate resolution is still effective for simple content viewed from a distance.

Resolution in Practice:

• High resolution: Best for small text, detailed graphics, or video on signs viewed up close.
• Moderate resolution: Ideal for bold messages, logos, and simple graphics seen from further distances.

How Do Pixel Pitch and Resolution Work Together?

Pixel pitch controls the spacing of pixels, and resolution is the total number of pixels. Together, they determine how sharp your outdoor LED sign will appear and at what distance it will look clear. Choosing the right balance ensures that your sign is not only legible but also eye-catching.

How Do You Choose the Right Pixel Pitch for an Outdoor LED Sign?

Ask yourself three key questions:

1. How far away will people view the LED sign?
   • treet-level and parking lot signs = 6mm-10mm
   • Highway or large roadside signs = 16mm-20mm
2. What type of content will you display?
   • Detailed graphics or video = higher resolution
   • Simple text or bold graphics = moderate resolution
3. What is your budget?
   • Smaller pixel pitch = higher cost, but may be worth it for signs viewed up close.
   • Larger pixel pitch = lower cost, but only effective if the audience is far away.

FAQ About Outdoor LED Sign Pixel Pitch and Resolution

Is higher resolution always better for outdoor LED signs?

Not necessarily. While higher resolution improves clarity, it also increases cost. For signs viewed at a distance, a moderate resolution looks just as clear as a high-resolution display.

What’s the best pixel pitch for outdoor LED signs?

• 6mm-10mm: For sidewalks, streets, and parking lots.
• 16mm-20mm: For highways and large roadside billboards.

How far away should you be to see an outdoor LED sign clearly?

A good rule of thumb is 1 millimeter of pixel pitch per 1 meter of viewing distance.

• 6mm pitch = clear from about 6 meters (20 feet)
• 16mm pitch = clear from about 16 meters (52 feet)
