m

Perimeter = 2 × (length + width). You can enter length and width — we will work it out.

m

Straight — pattern aligns horizontally; half-drop — on the diagonal, more waste.

cm

Trim allowance top and bottom. Usually 10 cm (5 cm each).

Total area of doors and windows that are not covered.

%

How much material to take beyond the calculation for trimming and defects. Usually 5–15%.

Strips: 17 · paste ≈ 1,701 g
How the figure is calculatedStrips: perimeter 18 m ÷ 1.06 m = 17. Strip 2.8 m (height 2.7 + 10 cm trim). A 10 m roll — 3 strips. Total: 17 ÷ 3 = 6 rolls.

Check the batch number on every roll — it must match, otherwise the shade will differ.

Sources and methodology
  • Strip cutting by height and pattern repeat
