Pixel Pitch Formula:
From: | To: |
Pixel pitch is the distance from the center of one pixel to the center of the adjacent pixel, typically measured in millimeters. It's a critical specification for displays, LED walls, and digital screens that determines the image sharpness and optimal viewing distance.
The calculator uses the pixel pitch formula:
Where:
Explanation: The formula calculates the center-to-center distance between adjacent pixels by dividing the total physical size by the number of gaps between pixels (which is always one less than the total number of pixels).
Details: Pixel pitch directly affects image quality and viewing experience. Smaller pixel pitch means higher pixel density, resulting in sharper images and shorter minimum viewing distances. This is crucial for designing display systems for various applications from digital billboards to high-resolution monitors.
Tips: Enter the physical size in millimeters and the number of pixels along that dimension. The pixel count must be at least 2 for the calculation to be meaningful.
Q1: Why subtract 1 from the pixel count?
A: We subtract 1 because the measurement is from the center of the first pixel to the center of the last pixel, which spans (pixels - 1) intervals.
Q2: What is a good pixel pitch value?
A: It depends on the application. For smartphones, values under 0.3mm are common. For large format displays, values from 1-10mm are typical. Smaller values generally provide better image quality.
Q3: How does pixel pitch relate to resolution?
A: Pixel pitch and resolution are related but different concepts. Resolution refers to the total number of pixels, while pixel pitch refers to the physical distance between them on the display surface.
Q4: Can I calculate pixel pitch for both width and height?
A: Yes, you would need to calculate separately for horizontal and vertical dimensions if the pixel density differs between axes.
Q5: Does pixel pitch affect viewing distance?
A: Yes, the minimum optimal viewing distance is typically calculated as (pixel pitch × 1000) to (pixel pitch × 3000) depending on the application and required image quality.
