Pitch vs. Resolution: Choosing the Right LED Density for Highway vs. Pedestrian Traffic

Demystifying Pixel Pitch

Pixel pitch refers to the center-to-center distance in millimeters between adjacent LED clusters (pixels). A smaller pitch (like P4 or P6) packs more LEDs into the cabinet for razor-sharp detail at close range, while larger pitches (P10 or P16) deliver maximum brightness and readability for long-distance highway viewing at lower hardware cost.

• P4 & P6 (High Density): Ultra-crisp detail for pedestrian plazas, drive-thrus, and slow city traffic (< 30 MPH)
• P8 & P10 (Commercial Standard): Balanced resolution and brightness for suburban commercial arterials (35–50 MPH)
• P16 (Highway Large Format): High-impact visibility for interstate freeways and high-rise pylon signs (60+ MPH)
• Viewing Distance Rule of Thumb: Minimum viewing distance (meters) ≈ Pixel pitch (mm)

Traffic Speed & Viewing Cone Calculation

Calculating driver exposure time based on road speed ensures passing motorists can comfortably read your message before driving past your frontage.

• Highway Traffic (65+ MPH): Motorists have a 4–6 second line-of-sight window; bold typography and high-contrast P10/P16 panels work best
• Arterial Roads (35–45 MPH): Allows multi-line text and dynamic product imagery on P6/P8 displays
• Pedestrian & Stop-and-Go Corridors: Crisp P4/P6 displays allow viewers to stand within 10–15 feet without seeing pixelation
