LED Video Wall Calculator

A planning tool that answers the core questions of an LED wall project: how many LED panels you need for a target width and height, the wall's pixel resolution from its pixel pitch, the minimum viewing distance, total power draw and how many circuits that means, total weight, curved-wall panel layout, and a ballpark budget. This page covers all five in one vendor-neutral lab.

With standard 500 x 500 mm cabinets: panels across = ceil(6000 / 500) = 12, panels high = ceil(3500 / 500) = 7, so 12 x 7 = 84 panels — an exact 6.0 x 3.5 m wall. With 500 x 1000 mm cabinets laid flat: 12 x 4 = 48 panels. Enter your exact target size and cabinet dimensions in tab 1 of the planner above.

The most common cabinets are 500 x 500 mm (rental / touring) and 500 x 1000 mm (fixed installs, fewer seams). Older and fixed-install tiles include 960 x 960 mm, 640 x 480 mm and 576 x 576 mm. Cabinet size matters because the grid layout rounds up: non-standard cabinets produce a slightly larger-than-target wall. Use the custom-size fields for your exact cabinet.

Pixel pitch is the distance in millimetres between the centres of two adjacent LED pixels. P2.6 = 2.6 mm. Lower pitch means denser pixels and higher resolution at the same wall size — but also higher cost, power draw and data load. Typical choices: P1.2-P2.6 for close-view indoor, P2.6-P3.9 for conferences and rental, P4.8-P6 for churches and retail, P8-P10+ for outdoor billboards.

Wall resolution in pixels = wall width in mm divided by pixel pitch in mm, rounded. Example: a 6 m (6000 mm) wall at P2.6 gives 6000 / 2.6 = 2308 px wide. A 3.5 m high wall gives 3500 / 2.6 = 1346 px. Per-cabinet pixels are panel width divided by pitch: 500 / 2.6 is about 192, so real P2.6 cabinets are typically 192 x 192 px. Tab 2 of the planner computes this for any wall size.

The industry rule of thumb: minimum viewing distance in metres = pixel pitch in millimetres. A P2.6 wall needs at least 2.6 m; P3.9 needs 3.9 m. Comfortable viewing is about 2x pitch (5.2 m for P2.6), and small text stays sharp up to about 3x pitch. Closer than the minimum, individual pixels become visible; beyond ~3x pitch a finer pitch buys no visible sharpness.

Total peak power = number of panels x max watts per panel. Example: 84 panels x 150 W = 12,600 W = 12.6 kW peak. Size breakers and cable for max, not average — average show content draws roughly a third of max, but switch-on inrush and white-screen content can reach peak. Tab 3 converts your panel count to kW and recommends 16 A / 230 V circuits: 12,600 / (16 x 230) = 3.4, rounded up to 4 circuits.

Circuits = ceil(total peak watts / (breaker amps x volts)). For a 12.6 kW wall on 16 A / 230 V circuits: ceil(12,600 / 3,680) = 4 circuits. Spread the load evenly across phases and add 20% headroom for inrush current on switch-on. Power distribution must be signed off by a licensed electrician or your AV integrator.

Total weight = panels x weight per panel: 84 panels x 12 kg = 1,008 kg — about a tonne. For flown (rigged) walls this is a structural load on the truss and hoists; for ground-stacked walls you need rated stacking frames and ballast. Rigging, truss and hoists must be certified — consult a structural engineer or certified rigger.

Arc angle in radians = arc length / radius; total degrees = angle x 180 / pi; panels along the arc = ceil(arc length / panel width); angle per panel = total degrees / panels. Example: a 10 m arc on a 5 m radius = 114.59 degrees total, 20 panels of 500 mm, 5.73 degrees per panel. Compare the per-panel angle with your cabinet's max curve spec (typically +/-5 to +/-15 degrees per cabinet).

Convex curves bow toward the audience (e.g. around a column), concave curves bow away (immersive wrap). Both use the same arc math. Convex cabinets join at their front edges, concave at their rear edges — the cabinet's locking mechanism determines which curves it supports. Tight radii under ~2 m usually need flexible/curvable cabinets rather than standard rigid ones.

Ballpark: panels ($300-$1,500+ each depending on pitch and indoor/outdoor rating), video processor ($1,500-$8,000), structure and cabling (~10-20% on top), install (~10-20% on top). Example: 84 panels at $450 = $37,800 + $2,500 processor + 15% install + 10% structure = $50,979.50, about $2,427.60 per m2. Rental is typically 3-8% of purchase price per event. Tab 5 builds a full estimate from your numbers.

Outdoor cabinets are far brighter (4,500+ nits vs 800-1,200 nits indoor) and IP65 weather-sealed; they are heavier and 20-40% pricier. Use outdoor only if the wall faces sun or weather — indoors you pay for brightness and sealing you cannot use. The cost estimator lets you set panel price tiers accordingly.

LED walls have no tuners or scalers: a video processor (controller) maps your content onto the wall's native pixel grid — e.g. scaling 1080p content to a 2308 x 1346 px wall — handles splicing across sending cards, multi-window layouts and switching between sources. Budget one for every wall, $1,500-$8,000 depending on 4K support and inputs.

LED walls are seamless (no bezels), scale to any size and aspect ratio, and work outdoors — but cost more per m2. LCD video walls are cheaper per m2 at small sizes but leave visible grid lines from the bezels. This planner is for LED video walls only; the panel math does not apply to LCD tiles.

Panel counts, resolution and viewing-distance results are exact arithmetic from your inputs. Power, weight, curve and cost results are planning estimates: per-panel specs vary by vendor and model, so enter your panel's datasheet values and always confirm with your vendor. For rigging, power distribution and structural work, consult a professional AV integrator.
