Free drop ceiling calculator: how many ceiling tiles, main tees, cross tees, wall angle and hanger wires you need per m². 2D/3D plan, no sign-up.
Profiles that run from wall to wall, typically spaced every 50cm. They support the drywall panels.
Fixed to the walls around the entire perimeter. The omega tracks rest on it.
Attach the omega tracks to the slab. Approximately 2.5 per m² is recommended for proper distribution.
Sheets = Area ÷ 2.88m² (standard 1.2m × 2.4m sheet size).
False ceilings with steel framing consist of a grid of profiles suspended from the structural slab. This calculator implements industry standards for accurate material estimation.
Number of omega = Length ÷ Spacing. Linear meters = Number of omega × Width.
Perimeter = (Length + Width) × 2. Pieces = Perimeter ÷ Profile length.
Hangers = Area × 2.5 (standard density for proper support).
Sheets = Area ÷ 2.88m² (standard 1.2m × 2.4m sheet size).
Reference values for a ceiling with omegas every 50 cm and a 40 cm drop. Always check the profile lengths from your supplier and the cutting waste:
| Material | Quantity | Unit | Notes |
|---|---|---|---|
| Omega Ceiling Track | ~22 | linear feet | ≈ 4 profiles of 6 m |
| Perimeter Channels | ~13 | linear feet | Room perimeter |
| Hangers | 25 | units | 2.5 per m² |
| Screws | 120 | units | 12 per m² |
| Drywall 1.2×2.4m | 4 | sheets | Area ÷ 2.88 m² |
The standard spacing is 40-60cm. Use 40cm for heavier loads or when installing insulation. 50cm is the most common for residential applications.
The standard is 2-3 hangers per m². Use 2.5 for standard loads and up to 4 per m² for heavy ceilings or those with additional insulation.
Standard hangers allow drops of 10-50cm. For greater heights, use wire hangers or threaded rods that can extend up to 150cm or more.
