How many flooring packs do I need?
Room area = length × width, or measured total area. Required coverage = area × (1 + waste/100). Packs = ceiling(required coverage ÷ coverage per pack). Purchased coverage = whole packs × pack coverage. Material cost = purchased coverage × your price per matching area unit.
Worked example
A 4 m × 3 m floor is 12 m². With 10% waste, plan for 13.2 m². Packs covering 2 m² require seven packs (14 m² purchased). If you enter an illustrative quote of 25 currency units/m², material cost is 350. No local price is assumed; the price input starts at 0.
Unit conversions
1 ft = 0.3048 m; 1 in = 0.0254 m; 1 cm = 0.01 m. Area conversions use squared length factors, and volume conversions use cubed factors. 1 yd³ = 27 ft³ = 0.764554857984 m³; 1 L = 0.001 m³.
Assumptions & limitations
- Pack coverage must come from the product label and use the selected area unit. Waste is extra material, not extra room area. Cost is based on whole packs purchased, not just the measured floor.
- Enter your own material price in the selected display currency per m² or ft². Currency selection performs no exchange-rate conversion. A zero price is an unpriced estimate, not a claim that flooring is free.
- Labor, underlay, adhesive, delivery, taxes and trim are excluded unless you incorporate them separately. Room geometry, board direction and patterns can increase waste; irregular floors must be measured or divided into simpler areas.
