How to use the Aspect Ratio Calculator
- Pick an aspect ratio preset (16:9, 4:3, 1:1, 21:9) or type a custom W:H.
- Choose your units — pixels, meters, or 0.5 m cabinets.
- Say whether you know the width or the height, then enter its value.
- Read the solved dimension plus the suggested cabinet grid and its physical size.
This aspect ratio calculator solves the everyday sizing problem: you know the ratio you want and one dimension, and you need the other. Choose a common ratio — 16:9, 4:3, 1:1 or 21:9 — or type any custom W:H, then enter a width or height in pixels, meters, or 0.5 m LED cabinets.
How it works
An aspect ratio is just the proportion width : height. Given a ratio and one side, the other follows directly:
- Height = width × ratioH ÷ ratioW
- Width = height × ratioW ÷ ratioH
For a 16:9 wall 4 m wide, the height is 4 × 9 ÷ 16 = 2.25 m.
Cabinet-grid suggestion
Because STENA builds walls from 0.5 × 0.5 m cabinets, the calculator also rounds your solved size to the nearest whole cabinet grid and shows the resulting physical size. A 16:9 wall 4 × 2.25 m becomes an 8 × 5 grid (40 cabinets, 4 × 2.5 m) since you can't hang a fraction of a cabinet.
Working in pixels, meters or cabinets
- Meters — best for planning the physical footprint against a venue.
- Cabinets — enter the grid directly; 1 cabinet = 0.5 m.
- Pixels — for content and canvas sizing; pair with the LED wall calculator to convert pixels to an exact panel count at a given pixel pitch.
Frequently asked questions
How do I calculate 16:9 dimensions from one side?
Multiply the width by 9 and divide by 16 to get the height (or multiply the height by 16 and divide by 9 for the width). A 4 m wide 16:9 wall is 2.25 m tall.
What is a 16:9 aspect ratio in meters for an LED wall?
Any size where width ÷ height = 16 ÷ 9. Common turnkey builds are 3.5 × 2 m, 4.5 × 2.5 m and 6 × 3.5 m — the calculator rounds any target to a whole 0.5 m cabinet grid.
What aspect ratios does STENA support?
16:9 widescreen, 1:1 square and 4:3 are standard, plus fully custom sizes — corner, trapezoid and curved layouts included. This tool also handles 21:9 and any custom W:H.
Why is the cabinet grid rounded?
A wall is physically built from whole 0.5 m cabinets, so a solved size is snapped to the nearest whole grid. Work in cabinets if you want the exact grid, and read the meters back.
