How the result break down
| Value wey e get |

Exact area versus extra area for waste
Dem scale di bars reach di bigger of di two areas. Di waste part na extra material for cuts and offcuts.
Area to buy for different waste allowances
| Allowance for waste | Value wey e get |
|---|
Length and width stay the same; na only waste allowance dey change.
Formula
Area = length × width. Perimeter = 2 × (length + width). Area to buy = area × (1 + waste rate).
Example wey show the calculation
Length na 6 m, width na 4 m: area = 6 × 4 = 24 m², perimeter = 2 × (6 + 4) = 20 m. With 8% waste allowance, waste area = 24 × 0.08 = 1.92 m², so area to buy = 25.92 m² (279 ft²). Na di example values above be dis; replace dem with your own measurements.
Where e fit work and limits
Dis calculation na for only one rectangle. Divide irregular spaces into rectangles wey you measure, then add dem. Check package coverage and di waste from di cutting pattern for your material; flooring, tiles and wallpaper no dey waste di same way. Di page no dey calculate price or assume any package size.
Questions wey people dey ask often
How the square area calculator dey work?
Area = length × width; area to buy = area × (1 + waste rate). Perimeter = 2 × (length + width).
Wetin if my room no be rectangle?
Divide irregular spaces into rectangles wey you measure, then add dem. L-shaped rooms na two rectangles, no be one rectangle wey you average.
Why area get waste allowance?
Cuts, offcuts, pattern matching and damaged pieces dey use material beyond di exact floor or wall area. Di percentage depend on di material and layout.
Wetin perimeter dey useful for?
Perimeter dey useful for edging, skirting, trim and border materials, wey dem dey buy by length instead of area.
I fit use feet instead of metres?
Yes, so long as length and width use di same unit: di area go come out in dat unit squared. Di breakdown still show di area to buy in ft² when you enter metres.
CalcMintly dey store values wey I enter?
No. This calculation dey run locally inside your browser; values wey you enter no dey reach any CalcMintly database.
