LED Display Power, Resolution & Aspect Ratio Calculator
A free specification tool for AV consultants, integrators, architects, installers and LED display buyers.
Enter your pixel pitch and screen dimensions to get the numbers that matter before you buy or specify an LED video wall: total power draw, native pixel resolution and 16:9 equivalent aspect ratio. The calculator covers electrical sizing, data cabling and resolution matching in one step, so you can brief your electrician, AV integrator and content producer from a single output.

How to Use the LED Display Calculator
- 1Enter your pixel pitch in millimetres. The centre-to-centre distance between LEDs on the panel — see our buying guide if you need help matching pitch to viewing distance.
- 2Enter your screen width and height in metres. Use the finished display dimensions, not the wall or recess size.
- 3Review the results. The calculator returns power, cabling and resolution figures you can drop straight into a tender document, electrical specification or content production brief.
What the Calculator Tells You
Each result maps to a specific stage of the specification and installation process.
- Total screen area (m²) — used for cabinet count estimates, freight sizing and structural load calculations.
- Total current (A) and power (kW) — the figures your electrical engineer needs to size the supply and distribution board.
- 13A switched spurs needed (Type C/D breakers) — hand this directly to your electrician for the final circuits brief.
- CAT5 data runs needed — tells your cabling contractor how many data runs to pull from the processor location to the display.
- Native pixel resolution (W × H) — the actual pixel count of the display, used to match the correct video processor output.
- 16:9 equivalent resolution — converts the native resolution to a standard broadcast ratio, useful when briefing content producers or motion graphics teams.
Pixel Pitch by Application
Pixel pitch is the distance in millimetres between the centre of one LED and the next. A smaller pitch means higher pixel density and a sharper image at close range, but it also increases the cost per square metre.
P0.9 to P1.5
Premium boardrooms, broadcast studios, control rooms. Designed for close viewing under 2 metres where text legibility and fine detail are critical.
P1.9 to P2.6
Corporate receptions, retail feature walls, conference rooms. Suits viewing distances of 2 to 5 metres and balances resolution against budget.
P2.9 to P3.9
Large retail installations, hotel lobbies, exhibition stands. Best at 5 to 10 metres where impact matters more than pixel-level detail.
P4 to P6
Outdoor advertising, building facades, sports venues. Built for 10 metres and beyond where brightness and durability take priority over fine pitch.

The calculator gives you the technical baseline, but a complete LED project also involves processor selection, content production, structural mounting and on-site installation. Our team specifies and installs LED displays across the UK and can take you from calculator output to a finished wall.
