Rental stage wall
- Target: 8 m x 4 m
- Cabinet: 500 mm x 500 mm
- Spares: 5%
Layout is 16 x 8 = 128 active cabinets, plus 7 spares = 135 total.
Rental projects often carry spares to handle shipping or event damage. Check lead times for replacements.

Cabinet quantity formula
Columns = ceil(target width mm / cabinet width mm)
Rows = ceil(target height mm / cabinet height mm)
Active cabinets = columns x rows
Order quantity = active cabinets + spare cabinets- ceil
- Round up
- Partial cabinet positions require a full cabinet or a changed layout.
- spares
- Spare cabinets
- Extra units for damage, service swaps, or event backup.
Cabinet quantity examples
Lobby display
- Target: 5 m x 2.5 m
- Cabinet: 500 mm x 1000 mm
- Spares: 3%
Layout is 10 x 3 = 30 active cabinets, plus 1 spare = 31 total.
Actual height becomes 3 m instead of 2.5 m. Adjust visual design or choose a different cabinet type.
Control room monitor wall
- Target: 3.2 m x 1.8 m
- Cabinet: 600 mm x 337.5 mm
- Spares: 2%
Layout is 6 x 6 = 36 active cabinets, plus 1 spare.
Close-to-target layouts are easier when the target size is near a multiple of cabinet dimensions.
Common mistakes in LED cabinet planning
Using generic cabinet sizes
Each LED product family has specific cabinet dimensions. Using rounded or assumed sizes leads to incorrect counts. Always get dimensions from the vendor's product specification.
Forgetting service and rigging clearance
Cabinet handles, locks, hanging brackets, curve hardware, and service access gaps increase the real installation footprint beyond the active screen area.
Not accounting for actual vs target size
Cabinet rounding often makes the actual screen larger than the target. This affects structural load, rigging design, content aspect ratio, and site space requirements.
Under-ordering spares for rental projects
Rental and touring projects face higher damage risk from shipping, assembly, and disassembly. Insufficient spares can halt a live event.
