Calculators

Working calculators for quick planning.

Enter the measurements you have, keep units consistent, and use the formula notes to understand how each result is estimated.

Siding & Exterior

Siding Square Footage Calculator

Estimate net siding wall area after opening deductions and waste.

Results

Enter the required measurements to calculate results.

Net siding area = gross wall area - openings. Buy area = net area x (1 + waste).

Help
  • Measure gables and wall faces separately for better accuracy.

Siding & Exterior

House Wrap Estimate

Estimate house wrap rolls from wall area, openings, waste, and roll coverage.

Results

Enter the required measurements to calculate results.

Rolls = (gross wall area - openings) x (1 + waste) / roll coverage.

Help
  • Overlap, seams, and product width affect real coverage.

Siding & Exterior

Soffit & Fascia Calculator

Estimate soffit area and fascia length from eave length and overhang.

Results

Enter the required measurements to calculate results.

Soffit area = eave length x soffit depth. Fascia length = eave length. Waste applies to both.

Help
  • Measure different overhang depths separately for better accuracy.

Siding & Exterior

Exterior Trim Length

Estimate exterior trim length with waste allowance.

Results

Enter the required measurements to calculate results.

Total trim = corner trim + window/door trim + band/frieze trim. Buy length = total x (1 + waste).

Help
  • Does not produce a cut list; profile changes should be calculated separately.

Siding & Exterior

Waste Factor Calculator

Apply a waste percentage to a measured quantity.

Results

Enter the required measurements to calculate results.

Order quantity = measured quantity x (1 + waste percentage). Waste quantity = order quantity - measured quantity.

Help
  • Use units consistently, such as sq ft, linear ft, pieces, or cubic yards.

Before You Calculate

Start with clear measurements.

Measure each wall face and major opening separately.

Record soffit, fascia, corner, and trim runs.

Note material profile and exposure assumptions for later calculator passes.
