LED Wall Size & Panel Calculator

A true 16:9 wall needs a column-to-row count that reduces to 16:9, so the smallest exact one is 16 × 9 cells — 8.0 m wide by 4.5 m high, 36 m². Hung the way the cabinet is built (upright, 500 mm wide and 1000 mm tall) that is 64 × 1000 × 500 plus 16 × 500 × 500: nine rows is an odd number, so every one of the sixteen columns finishes with a half panel. Anything smaller is an approximation — 7 × 4 cells (3.5 × 2.0 m) is 1.6 % narrow and takes 14 upright 1 m panels with no half panels at all, and 9 × 5 cells (4.5 × 2.5 m) is 1.25 % wide and takes 18 upright 1 m panels plus 9 half panels. Both look like 16:9 on site once content is filled rather than fitted.

Resolution is the cell count multiplied by the pixels across one 500 mm cabinet, which is set by the pixel pitch. At P2.604 a 500 mm cell is 192 × 192 px, so an 8.0 × 4.5 m wall (16 × 9 cells) is 3072 × 1728 px — 5.3 megapixels, comfortably inside a 4K canvas. At P3.906 the same wall is 2048 × 1152 px. Which way the 1 m cabinets hang makes no difference to any of it: a 1 m cabinet is 192 × 384 px upright and 384 × 192 px on its side, so the wall lands on the same pixel count either way. Rotating a cabinet moves seams, not pixels.

Pitch is the distance between LED pixels, and it sets how close a viewer can stand before they see the pixel structure. As a planning rule the picture is pixel-perfect from about 3.4 × the pitch in metres — P2.6 from roughly 9 m, P3.9 from roughly 13 m. Indoor conference and stage walls are usually P2.6 to P3.9; outdoor daylight walls are P4.8 and coarser, and need 4500+ nits rather than the 1000-odd nits an indoor cabinet produces.

No, and it rarely can. Because the wall is built from 500 mm cells, the achievable ratios are whatever cols ÷ rows gives you. A mismatch under about 2 % is invisible once the content is scaled to fill and cropped rather than letterboxed, so the calculator ranks the nearest buildable walls and shows how far each one sits from your target rather than pretending an exact match exists.

Because the 1 m cabinet stands upright, a wall built only from them can only be an even number of ROWS — the height jumps in 1 m steps. The 500 × 500 is the half-step: it closes an odd row count, trims a wall to a stage opening, and gets you shapes like 9 × 5 cells (4.5 × 2.5 m) that a pure stack of 1 m panels cannot reach. Watch the arithmetic though: an odd row count costs one 500 × 500 in EVERY column, so a 9-column wall at 5 rows needs 9 of them. A useful rule of thumb is one 500 × 500 per column of your widest odd-height wall.

Sometimes, and the calculator has a setting for it. Upright is the native orientation — the cabinet is 500 mm wide and 1000 mm tall, so it fills two cells stacked in one column. Turned on its side it fills two cells side by side in one row, and everything mirrors: height then moves in 0.5 m steps and width in 1 m steps, and it is an odd COLUMN count that costs one 500 × 500 in every row rather than an odd row count costing one per column. It only works if the cabinet has locks and hanging hardware on all four edges and the receiving card scan direction can be rotated, which many rental cabinets cannot do — check with your supplier. Nothing else changes: the size, the resolution, the aspect ratio and the power draw are identical either way, because rotating a cabinet moves seams, not pixels.

Yes — it returns planning figures for panel weight, rigged weight, peak power draw, the number of 10 A or 32 A three-phase circuits, data ports, receiving cards and a suggested controller class. They are planning figures for scoping a job, not a sign-off: the final numbers come from the datasheet of the cabinet you actually buy, and any flown wall needs a qualified rigger.
