How to use this calculator

  1. Measure the project or enter costs from a current quote or product label.
  2. Adjust the quantities, coverage, package size, and allowances to match your situation.
  3. Select Calculate, then check the method, worked example, and limitations below.

Formula and method

Fabric area = measured bed area × (1 + overlap and waste%). Divide by roll area and round rolls up.

Whole packages and pieces are rounded up. Results disappear when an input changes until the new values are calculated.

Worked example

Bed area 420 sq ft; Overlap and waste 20 %; Roll width 4 ft; Roll length 50 ft. Results: Fabric area 504 sq ft; Whole rolls 3 rolls.

The example uses the values initially displayed in the fields.

Limitations

Strip layout, plant openings, slopes, pins, and seams may need more material than an area-only calculation.

Review and reference

Reviewed October 5, 2026. The default example, input boundaries, arithmetic, rounding, and invalid input behavior were checked. The method is explained on How Our Calculators Work; replace example inputs with measurements or current product specifications. This is a planning estimate.
