Almost every rental LED range offers two cabinet sizes built on the same module grid: 500 × 500 mm and 500 × 1000 mm. They cost roughly the same per square metre and produce the same image. What changes is how the wall goes up, how it comes down, and what shapes you can build.
The short answer
Use 500 × 1000 cabinets for large flat walls — fewer pieces, fewer connections, faster build. Use 500 × 500 cabinets for anything with an unusual height, a curved section, a low ceiling or a stepped edge. Most rental fleets end up buying both.
What actually differs
Both cabinets carry four 250 × 250 mm modules. On a 500 × 1000 cabinet those modules are stacked two high; on a 500 × 500 cabinet they form a square. The pixel grid moves in 250 mm steps in either case, so the two sizes bolt together freely in the same screen — as long as the pixel pitch matches.
| 500 × 500 mm | 500 × 1000 mm | |
|---|---|---|
| Modules per cabinet | 4 (2 × 2) | 4 (2 × 2, taller) |
| Typical weight, indoor | about 7 kg | about 12 kg |
| Typical weight, outdoor | about 8 kg | about 13 kg |
| Pieces for a 6 × 3 m wall | 72 cabinets | 36 cabinets |
| Power and data links to make | roughly twice as many | roughly half |
| Height increments | 0.5 m | 1.0 m (or 0.5 m when mixed) |
| Curved builds | tighter radius | wider radius |
Why cabinet count matters more than weight
A 6 × 3 m wall needs 72 pieces in 500 × 500 or 36 pieces in 500 × 1000. That difference is not cosmetic. Every cabinet brings a power link, a data link, four or more locks and one more chance of a misaligned seam.
Doubling the cabinet count roughly doubles the labour. On a one-day load-in, that labour is often the single largest cost line, well above the difference in hardware price. This is the strongest practical argument for the larger cabinet.
Where 500 × 1000 wins
- Large flat walls. Fewer seams means a cleaner image and less time spent chasing alignment.
- Fast turnarounds. Half the pieces means roughly half the handling, and fewer people on the truss.
- Cable management. Fewer power and data runs, which matters on a 20 m wide backdrop.
- Weight per square metre. A taller cabinet is not proportional to its height in weight, because the frame is shared across four modules. Two 500 × 500 cabinets usually weigh slightly more than one 500 × 1000.
The EA1000H9 500 × 1000 mm cabinet is built for exactly this case: 13 kg outdoors, 12 kg indoors, front and rear service access, and optional arc locks.
Where 500 × 500 wins
- Odd heights. A 2.5 m high wall is impossible in 1 m steps without cutting; it is trivial in 0.5 m steps.
- Low ceilings and stairwells. Smaller pieces go where a 1 m tall cabinet will not.
- Curves. A shorter cabinet follows a tighter radius, so rings, cylinders and 90-degree corners are easier to form.
- Small builds. For a 2 × 1.5 m screen, 500 × 1000 cabinets waste both money and weight.
- Crew size. 7 kg can be handled by one person on a ladder; 13 kg really wants two.
The EA500H9 500 × 500 mm cabinet covers that side of the range, on the same module grid and with the same locks.
Can you mix them in one wall?
Yes, and this is the part most buyers miss. Because both sit on a 250 mm module grid, a 500 × 1000 cabinet bolts directly to a 500 × 500 cabinet horizontally and vertically. That lets you build a taller centre band, a stepped edge, a logo shape or a 2.5 m high wall without buying a second product line.
The constraint is pitch: you cannot mix P3.91 with P4.81 in one continuous surface. You can mix cabinet sizes within the same pitch all day.
The rigging and case question
Check three things before committing to a cabinet mix:
- Hanging bars and clamps are usually cabinet-specific. A mixed fleet needs both sets.
- Flight cases are dimensioned for the cabinet. A 500 × 1000 case holds fewer pieces and weighs more when full — check it still fits your truck and your lift.
- Weight per square metre on the truss. Heavier cabinets are not always worse, because fewer connections often means less hardware overall, but the point load per cabinet is higher.
Frequently asked questions
Which builds faster?
500 × 1000, for any wall taller than 1 m and wider than 2 m, mainly because there are half as many pieces and connections.
Which is better for touring?
Most tours carry 500 × 1000 as the main stock and a smaller quantity of 500 × 500 for edges, stairs and height oddities.
Is image quality different?
No. If both use the same pitch and the same LED generation, the image is identical. Only the seam pattern changes.
Can a 500 × 500 cabinet be hung from a 500 × 1000 cabinet?
Yes, on the shared 250 mm grid, provided the locks and load path are designed for it. Confirm with the manufacturer for your specific cabinet family.
