LED Wall Calculator
Enter the size you want and the pixel pitch. You get cabinet count, the real wall size once it snaps to whole cabinets, resolution — and the two numbers most calculators leave out: how much it weighs and how much power it draws.

An LED wall can only be built in whole cabinets, so the real size rarely matches the target exactly. Weight and power are estimates from the figures above — replace them with your panel supplier’s real datasheet values before engineering.

Nothing here is proprietary — it is the arithmetic every LED integrator does by hand, made repeatable.
| Output | How it is derived |
|---|---|
| Cabinet count | Target size ÷ cabinet size, rounded to whole cabinets in each direction |
| Real wall size | Cabinet count × cabinet size — this is what actually gets built |
| Resolution | Pixels per cabinet (cabinet size ÷ pitch, rounded to whole pixels) × cabinet count — how panels are actually built |
| Weight — generic cabinet | Screen area × kg per m² (cabinet, frame and fixings included) |
| Weight — joeqing rotating layer | Module count × the published weight of one complete layer (40 kg for 1280 × 320 mm, 30 kg for 750 × 250 mm), which already includes frame, bearing and drive |
| Power, average | Screen area × W per m² at typical content brightness |
| Power, peak | Roughly 3 × average — the figure the venue’s supply has to cover |
| Viewing distance | Minimum ≈ pixel pitch in mm read as metres; comfortable ≈ 3 × that. Both are trade rules of thumb, not optics |
Pixel pitch should be chosen from how close people stand, not from a resolution target. Buying a finer pitch than the room needs is the most common way to overspend on an LED wall.
Why this calculator also gives you weight and load
Most LED wall calculators stop at pixels. That is fine if the wall is bolted to a structure someone else already engineered. It is not fine if the wall has to hang, lift, fold or rotate.
We build the mechanical structure and motion control behind moving LED walls, so weight is the first number we ask for — it sets the drive, the bearing, the braking and the safety case. A 6 × 3 m wall at 35 kg/m² is about 630 kg of moving mass. That is a structural problem before it is a display problem. Build the same surface out of rotating layers and the moving mass is several times higher, because every layer carries its own frame, bearing and drive — the single most common sizing mistake in the enquiries we receive.
If the wall has to move
Take the weight figure above to the platform that matches the motion you need: a foldable lifting screen for portable deployment, a multi-layer rotating screen for continuous rotation, a telescopic matrix for surfaces that expand and contract, or an outdoor rotating landmark where wind load joins the calculation. All seven are compared on the motion platforms page.
We also supply the mechanical structure and control system on its own, to LED manufacturers and integrators who bring their own panels.
LED wall calculator FAQ
How many LED cabinets do I need for my wall?
Divide your target width and height by the cabinet dimensions and round to whole cabinets. An LED wall can only be built in whole cabinets, so the real wall size is almost never exactly the size you asked for. The calculator rounds for you and shows the difference.
What resolution will my LED wall have?
Resolution comes from the pixel count of one cabinet multiplied by the number of cabinets. A 500 mm cabinet at 2.6 mm pitch carries 192 pixels per side, so a 6 m wide wall of twelve cabinets is 2,304 pixels across. Finer pitch means more pixels and higher cost for the same physical area, so pitch should be chosen from viewing distance, not from a resolution target.
How much does an LED wall weigh?
Indoor rental and fixed cabinets typically run 25 to 45 kg per square metre including frame; outdoor cabinets are heavier. Weight matters more than most buyers expect, because the supporting structure, hoist or rotating mechanism has to be engineered around it. The calculator uses an editable figure so you can enter the real number from your panel supplier — and if the wall moves, use the weight of the actual moving assembly rather than a flat panel figure, because the two are nowhere near each other.
Why does an LED wall calculator ask about weight and power?
Because those two numbers decide whether the wall can be hung, lifted or rotated at all. Pixel count tells you what the picture looks like; mass and power tell you what the structure and the venue have to provide. If the wall has to move, weight also drives the drive and braking specification.
What viewing distance should I design for?
A common rule of thumb is that the minimum viewing distance in metres is roughly the pixel pitch in millimetres, and that a comfortable distance is about three times that. At 2.6 mm pitch that is roughly 2.6 m minimum and 7.8 m comfortable. It is a starting point for specification, not a substitute for a site review.
How much does a rotating LED layer weigh?
A joeqing 1280 × 320 mm curved rotating layer weighs 40 kg, and a 750 × 250 mm rectangular layer weighs 30 kg. Those are complete-layer figures covering the LED, the frame, the bearing and the drive, which is why they work out at roughly 98 and 160 kg per square metre against about 35 kg per square metre for a plain indoor cabinet. Sizing a rotating wall from a flat panel weight underestimates the moving mass several times over, so select the module in the calculator instead of typing a kg per square metre figure.
Reference only
Every figure on this page is an estimate. It is produced from the values you entered and from standard trade arithmetic — it is not a quotation, not an engineering calculation, and not a guarantee that any number is correct for your project. Real cabinet counts, weight, power draw and viewing distance depend on the exact panel you buy, the structure it mounts to, and the site itself. Treat the results as a starting point for a conversation, and confirm every number against your panel supplier’s datasheet and a qualified engineer before you order, rig or build anything.
