How it's calculated (visible formula)
tiles = ceil(area ÷ tile × (1 + waste)); main runners ≈ 0.83 m/m²; hangers ≈ 0.7 per m²; cost = area × price
- Net geometric measurement, no waste.
- Adjustable waste % for cuts and breakage.
- Purchase rounded up to sellable units (boxes, bags, buckets, boards).
How to calculate it, step by step
- Measure the space and deduct columns or open areas.
- Choose tile size (2×2 or 2×4).
- Work out tiles with waste and grid per area.
- Work out wall angle and hanger wires.
- Multiply area by your installed price and add extras.
Worked example: 33 × 26 ft office, 2 × 2 tiles at $22/m²
- 80 m² ÷ 0.36 ≈ 222 → +5% = 234 tiles
- Cost: 80 × $22 = $1,760
→ $1,760, 234 tiles, 20 main runners and 56 hangers.
Common mistakes
- Not deducting lay-in lights and diffusers.
- Forgetting moisture-resistant tiles in wet areas.
- Leaving wall angle out of the estimate.
Pro tips
- Coordinate with electrical and HVAC — lights and diffusers sit in the grid.
- Use moisture-resistant tiles in kitchens and restrooms.
- Leave spare tiles for maintenance.
- Check fire-rated assemblies required for the occupancy.
