LED Wall Calculator
Use our professional LED wall calculator (also known as an LED screen calculator or LED video wall calculator) to determine exact cabinet counts, screen dimensions, pixel pitch, total resolution, and power requirements for your custom LED display. This tool is designed for event planners, AV integrators, and businesses to quickly plan C Series fixed-install and R Pro Series rental LED screens.
Understanding LED Wall Dimensions & Resolution
What is Pixel Pitch?
Pixel pitch (measured in mm) is the distance from the center of one LED cluster to the center of the next. A smaller pixel pitch (e.g., 1.2mm or 2.5mm) means higher pixel density and higher resolution, making it ideal for close-up viewing. A larger pitch (e.g., 3.9mm or 5.9mm) is better suited for larger displays viewed from a distance.
Aspect Ratios Explained
The aspect ratio is the relationship between the width and height of your LED screen. The most common standard is 16:9 (Widescreen), used for most video content. Other ratios include 4:3 (Standard) or 21:9 (Ultrawide). Our calculator helps you achieve these ratios by selecting the right number of cabinets.
Viewing Distance Rule
The "rule of thumb" for minimum viewing distance is approximately 1 meter for every 1mm of pixel pitch. For example, a 2.5mm LED wall is best viewed from at least 2.5 meters away. A "comfortable" viewing distance is typically 1.5x to 2x that minimum.
How we calculate LED Screen Size
To ensure accuracy, our LED wall pixel pitch calculator and LED display power calculator use several key metrics based on actual hardware specifications:
- Cabinet Counts: We divide your target width and height by the specific dimensions of the selected LED cabinet (e.g., 500x500mm or 960x960mm) and round up to the nearest whole cabinet.
- Total Resolution: Calculated by multiplying the number of cabinets by the pixels per cabinet (width_mm ÷ pixel_pitch).
- Physical Dimensions: The final screen size is the total count of cabinets multiplied by their individual width and height.
- Power Requirements: We estimate typical power draw based on average usage (C Series ≈ 280 W/m², R Pro ≈ 220 W/m²). Max power may be higher.
- Weight: Estimated based on standard panel weights for each series and size.
How to Estimate LED Wall Costs
LED wall costs are determined by three main factors: pixel pitch, total area, and installation type. Smaller pixel pitches (higher resolution) cost significantly more per square meter. Rental displays often include additional costs for rigging and processing. Use our LED screen calculator to see an estimated budget based on your chosen series.
Calculating Rigging and Weight for LED Walls
Safety is paramount when installing large LED displays. Our LED video wall calculator provides an estimated total weight for your configuration. Ensure your rigging points or ground support system can handle at least 1.5x the total weight of the panels plus the weight of the cables and processors.
Frequently Asked Questions
How do I calculate the size of an LED wall?
To calculate LED wall size, you must first know the dimensions of the individual LED cabinets. Divide your desired total width by the cabinet width to get the horizontal count, and repeat for the height. Multiply these counts by the cabinet dimensions to get the final physical size.
What size LED wall do I need for a 16:9 aspect ratio?
For a standard 16:9 ratio, you need the ratio of horizontal cabinets to vertical cabinets to match 1.77:1 as closely as possible. For example, using 500x500mm panels, a 16x9 cabinet configuration (8m x 4.5m) creates a perfect 16:9 screen.
How does pixel pitch affect LED wall size and resolution?
Pixel pitch determines the resolution (total pixels) within a fixed physical area. A smaller pixel pitch allows for higher resolution (more pixels) on a smaller screen, while a larger pixel pitch requires a larger physical size to achieve the same resolution.
How many LED panels do I need?
The number of LED panels depends on your target screen size and the size of the individual panels. Use our LED cabinet dimensions tool above to select a model; the calculator will automatically output the total number of panels required to fill your space.
