Live result19.80 m²18.00 m² measured + 10.0% waste · 193.75 sq ft measured
Formula used

Measured area = Σ(length × width) for each rectangular section. Flooring planning area = measured area × (1 + waste percent ÷ 100). Square feet = square metres ÷ 0.09290304.

This is the method behind the answer, so the result can be checked rather than simply trusted.

Assumptions used

What this answer assumes

Measured area first, waste allowance second. Round pack orders only after checking supplier coverage.

  • Each entered section is treated as a rectangle measured in metres.
  • Unused rows can stay at 0 and do not add area.
  • Waste allowance is a planning estimate for cuts, offcuts, pattern direction, damaged boards or measurement tolerance.
  • The calculator does not choose flooring packs, batch numbers, labour, trims, underlay, adhesives, doorway cuts or installer rules.

Master’s Tip

How to use the result well

Master’s Tip: split awkward rooms into rectangles, write the section measurements down, then add waste after the measured area. Keep pack coverage and supplier rounding as a separate final check so the quote trail stays clear.

What-if check

Waste allowance comparison

Measured area stays separate from ordering allowance. Use the rows to compare a clean worksheet total against common waste settings before pack rounding.

Visual grid

This result measures part of the space you live in

Length, area, volume and material estimates are grid problems too: measure the space, account for edges and allowances, then turn the pattern into a number you can use.

Space calculations turn a real surface, room, run or volume into cells, edges and allowances that can be quoted, ordered or checked.

Method

Measured area = Σ(length × width) for each rectangular section. Flooring planning area = measured area × (1 + waste percent ÷ 100). Square feet = square metres ÷ 0.09290304.

  1. Room 1 is 4.2 × 3.6 = 15.12 m². Room 2 is 2.4 × 1.2 = 2.88 m². Total measured area is 18.00 m². With 10% waste: 18.00 × 1.10 = 19.80 m². The same measured area is about 193.75 sq ft.

Assumptions

  • Each entered section is treated as a rectangle measured in metres.
  • Unused rows can stay at 0 and do not add area.
  • Waste allowance is a planning estimate for cuts, offcuts, pattern direction, damaged boards or measurement tolerance.
  • The calculator does not choose flooring packs, batch numbers, labour, trims, underlay, adhesives, doorway cuts or installer rules.
