Sizes are active picture area, so add mounting clearance and structure before you commit to a wall opening. Power figures are rough industry averages: check the spec sheet before sizing circuits.
Two technologies, one set of numbers to check
Whether a wall is built from LCD tiles or LED cabinets, the same four questions decide whether the design survives contact with the room: how big is it, how many pixels does it have, how close can people stand, and what does it draw. Get those on paper before anyone measures the wall, because a layout that is 80 mm too wide for the alcove is a problem you only discover on install day.
What the calculator uses
- LCD: the 16:9 diagonal split into width and height, plus the bezel-to-bezel gap between tiles.
- LCD resolution: 1920 by 1080 per tile, the standard for commercial video wall panels.
- LED: cabinet dimensions multiplied out, with resolution derived from cabinet size over pixel pitch.
- Viewing distance: pitch in millimetres as metres, a conservative starting point for LED.
- Power: about 0.5 W per inch of LCD diagonal, about 170 W/m² average and 500 W/m² peak for LED.
All dimensions are active picture area, so add mount depth, service clearance, and any trim before you commit to an opening. Placing the wall in a real room? Avitly puts it on the floor plan at true scale, so the size you calculate here is the size the client signs off on.
Common questions
How do I work out the size of an LCD video wall?
Take the panel diagonal, split it into width and height using the 16:9 ratio, then multiply by the number of columns and rows and add the bezel-to-bezel gap between each neighbouring pair. A 55 inch panel works out to about 1218 by 685 mm of picture, so a 3 by 3 wall with 3.5 mm seams lands near 3.66 by 2.06 m. The figure is active area only: leave clearance for the mount, the service gap, and any trim.
What pixel pitch do I need for a given viewing distance?
The working rule is that the pixel pitch in millimetres is roughly the closest comfortable viewing distance in metres. A 1.9 mm wall reads clean from about 2 m, a 2.5 mm wall from about 2.5 m, a 6 mm wall from 6 m and up. It is a conservative starting point, not a hard limit: content matters, since fine text and thin lines need a tighter pitch than photography or video, and a wall people only glance at from across a lobby can go coarser than the rule suggests.
Should I choose LCD tiles or direct-view LED?
LCD tiles are cheaper per square metre at small sizes, give you a very high pixel density up close, and are simple to service one panel at a time. The trade-off is the seam: even a 0.88 mm bezel is a visible grid on a light background. Direct-view LED has no seams and scales to any shape or size, but the cost climbs steeply as the pitch gets finer, and it needs more power, more cooling, and a processor. Under about 4 m wide with viewers at desk distance, LCD usually wins on budget. Anything larger, curved, or in a bright space tends to go LED.
How much power does a video wall draw?
This tool gives a planning estimate: roughly 0.5 W per inch of diagonal per LCD panel, and about 170 W per square metre average with 500 W per square metre peak for LED. Peak only happens on full white content, which real material almost never sustains, but the circuit and the power distribution have to survive it anyway. Size the supply on peak, size the cooling and the running cost on average, then confirm both against the manufacturer spec sheet before the electrician quotes.
What resolution will the finished wall be?
For LCD, nearly every commercial video wall panel is 1920 by 1080, so a 3 by 3 wall is 5760 by 3240, about 18.7 megapixels. For LED, divide the cabinet dimensions by the pixel pitch: a 500 by 500 mm cabinet at 1.9 mm is 263 by 263 pixels, so a 6 by 3 layout gives 1578 by 789. Note that LED resolutions rarely land on a neat broadcast standard, which is exactly why you need a processor that scales and maps the source to the physical canvas.
What does the calculator not account for?
Mounting depth, structural load, cable routing, and the processor are all outside the numbers here. A large LED wall can weigh over 30 kg per square metre once the frame is included, and both technologies need rear or side service access unless the cabinets are front-serviceable. Ambient light also matters: a wall facing glazing needs far more brightness in nits than the same wall in a controlled room, and brightness drives power and heat straight back into the figures above.
