1. What is a Pixels per Foot Calculator?

Definition: This calculator determines the pixel density (PPF) for displays or LED strips by dividing total pixels by length in feet.

Purpose: It helps designers, installers, and technicians calculate pixel density for digital displays, LED installations, and screen configurations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( PPF \) — Pixels per foot (pixels/ft)
• \( P \) — Total number of pixels (unitless)
• \( L \) — Length in feet

Explanation: The total pixel count is divided by the physical length to determine how densely packed the pixels are.

3. Importance of PPF Calculation

Details: Proper PPF calculation ensures correct resolution planning, optimal viewing distances, and accurate material requirements for digital displays.

4. Using the Calculator

Tips: Enter the total number of pixels and the physical length in feet. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical PPF for LED walls?
A: Common values range from 10-60 PPF, depending on viewing distance and application (indoor/outdoor).

Q2: How does PPF relate to PPI (pixels per inch)?
A: PPF × (1/12) = PPI. Multiply PPF by 0.0833 to convert to pixels per inch.

Q3: When would I need this calculation?
A: When designing LED displays, video walls, digital signage, or any pixel-based linear display system.

Q4: Does this work for curved displays?
A: Yes, but use the actual linear length (not curved length) for most accurate density calculations.

Q5: What if I know pixel pitch instead?
A: PPF = 1 / (pitch in feet). For pitch in mm: PPF = 304.8 / pitch_mm.
