Формула

Area (sq ft) = Length × Width | Area (m²) = Length × Width | Waste allowance: +10% for seams and cuts | Density affects durability

Ръководство стъпка по стъпка

1Calculate room area = Length × Width
2Add 10–15% for wastage and pattern matching
3Consider carpet width: standard rolls are 3m, 3.66m, or 4m wide
4Irregular rooms: divide into rectangles, sum areas, add wastage

Worked Examples

Вход

Room 4m × 3.5m, no pattern

Резултат

Area = 14m²; with 10% wastage = 15.4m²; one strip from 4m wide roll works
