Calculators
Start with the measured material
Exterior Projects
Siding Calculator
Estimate siding for measured house walls, windows and gables; then turn square footage into actual supplier quantities. Use product-listed coverage or lap-plank length and installed exposed reveal, compare individual pieces with cartons and measure accessories separately.
Exterior Projects
Gable Siding Calculator
Measure the triangular siding wall below a gable roof, including symmetrical, off-center ridge and single-slope shed ends. Derive vertical rise from roof pitch where supported, calculate each sloping rake edge for trim stock, deduct gable openings and obtain real supplier package quantities and optional material-only quotes.
Exterior Projects
Siding Square Calculator
Decode a contractor or supplier quote in siding trade squares (100 square feet each), or use known wall area. Convert to net square footage, optional waste, unopened product-specific cartons and leftover coverage; compare user-entered material rates per trade square versus full box without inventing market prices.
Exterior Projects
Vinyl Siding Calculator
Convert a measured single wall or previously measured gross siding area into vinyl panel and carton quantities. Cross-check actual panel reveal against printed box coverage, see where a full-course order differs from ideal square footage and enter real supplier prices instead of guessed costs.
Exterior Wall Materials
Stucco Calculator
Calculate base-coat and finish-coat purchases separately. Deduct measured openings, use coverage for the specified coat thickness, and round each product only after combining its required quantities.
Exterior Materials
Stone Veneer Calculator
Plan manufactured or thin-stone veneer quantities with editable product coverage.
Masonry Materials
Brick Calculator
Estimate bricks and optional product-specific mortar for a measured single wall face.
