Landscape Materials
Calculate cubic yards, US tons, metric tonnes and whole bags for one or several rectangular or circular gravel areas. See what to order when a yard has minimum loads, half-yard increments or delivery charges; use real supplier product details.
Interior Materials
Estimate how many drywall sheets a room needs, or measure multiple walls and ceiling planes individually. Compare 4×8, 4×10 and 4×12 sheet orders with actual supplier prices, optional screw/tape/compound package sizes, and transparent opening and waste assumptions.
Exterior Projects
Estimate fence posts, sections, rails, pickets and panels. A straight ungated fence shows equal spacing; for gates, optionally enter each measured run to calculate separate bay counts rather than relying on conservative totals.
Exterior Projects
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.
Deck Planning
Calculate deck board quantities and see the exact last-board fit before you buy. Compare fixed gaps, matching edge rips and full-width board layouts using your decking product’s allowed gap limits.
Exterior Projects
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
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
Estimate whole fence panels for separate clear runs, or use a quick pooled length estimate with gate deductions.
Interior Materials
Estimate ceiling-only drywall sheets after cutouts and waste. Compare 4 × 8, 4 × 10, 4 × 12 or custom sheets, with a separate approximate screw quantity.
Exterior Projects
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.
Erosion Control Materials
Estimate riprap rock for a measured bank or flat bed. Calculate the real slope-face width from horizontal run and rise, then use the designed layer thickness and supplier bulk density.
Drainage Materials
Turn an already planned gravel-filled French drain into a transparent material takeoff. Subtract the pipe’s outside volume from the stone envelope and calculate pipe stock and fabric wrap separately.
Exterior Wall Materials
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.
Area
Measure rooms, floors, walls, and multi-area projects.
Volume
Plan slabs, footings, columns, and post holes.
Coverage
Plan room walls, ceilings, known surfaces, and local paint purchases.
Materials
Estimate tile size, box quantity, pattern allowance, and purchase cost.
Materials
Plan flooring cartons, product coverage, underlayment rolls, and budget.
Drywall
Plan drywall mud purchases with editable product coverage and container size.
Drywall
Plan joint tape rolls, waste, and local purchase cost.
Landscape Materials
Plan fabric strip layout and perimeter or seam fasteners for beds and paths.
Interior Trim
Plan mitered or craftsman door trim before purchasing and cutting stock.
Interior Trim
Plan room crown molding quantities before ordering stock and laying out cuts.
Exterior Materials
Plan manufactured or thin-stone veneer quantities with editable product coverage.
Tile Materials
Plan grout and setting-material purchases for floor, wall, backsplash, and shower tile.
Floor Preparation
Plan floor-leveling compound and primer before tile or flooring installation.
Floor Preparation
Plan shower pans and mortar beds with editable product yield and average thickness.
Masonry Materials
Plan real block dimensions and supplier quantities for a wall face, without assuming one product yield.
Masonry Materials
Estimate bricks and optional product-specific mortar for a measured single wall face.
Landscape Materials
Turn a patio footprint into separate ready-to-order base gravel and bedding sand quantities.
