Construction Calculators
Materials, area and project estimators.
Flooring Calculator
Estimate flooring area and cost, including a waste allowance — turning simple room dimensions into a realistic purchase quantity and budget.
Concrete Calculator
Estimate the concrete volume and number of bags needed for a slab — converting simple length, width, and depth measurements into an actionable material order.
Mulch Calculator
Find how many cubic yards of mulch you need to cover a garden bed — converting bed area and target depth into a purchasable material quantity.
Tile Calculator
Estimate how many tiles you need for a floor or wall — converting floor area and individual tile size into a purchasable unit count with waste allowance.
Brick Calculator
Estimate how many bricks you need for a wall — a straightforward area-based calculation that scales with your specific brick size and coursing pattern.
Drywall Calculator
Find how many drywall sheets you need for a given wall or ceiling area — a simple coverage calculation across the three common sheet sizes.
Roofing Calculator
Estimate roof surface area from footprint dimensions and roof pitch — since a pitched roof always has more surface area than its flat footprint suggests.
Stud Spacing Calculator
Find how many wall studs you need for a given wall length and spacing — a foundational framing calculation built around the standard 'on center' spacing convention.
Fence Calculator
Estimate the posts and panels needed for a fence — using the simple but easily-miscounted relationship between fence length, post spacing, and post count.
Paint Calculator
Estimate how much paint you'll need for a wall, accounting for doors and windows — turning simple wall measurements into a realistic purchase quantity.
Paver Calculator
Find how many pavers you need for a patio or walkway, including a waste allowance — converting area and paver size into a purchasable unit count.
Stair Calculator
Find the number of steps and exact riser height for a staircase — solving the practical problem of dividing a fixed total rise into equal, code-compliant steps.
Topsoil Calculator
Find how many cubic yards of topsoil you need to fill or level an area — converting area and target depth into a supplier-ready order quantity.
Deck Board Calculator
Find how many deck boards you need for a given deck area — accounting for board coverage and a realistic waste allowance for cuts and staggered seams.
Asphalt Calculator
Estimate the tonnage of asphalt needed for a driveway or paving project — since asphalt is ordered by weight, not area or volume.
Gravel Calculator
Estimate the volume and weight of gravel needed for a path or driveway — converting simple area and depth measurements into an order quantity suppliers can actually fulfill.
Insulation R-Value Calculator
Find the total R-value of an insulation layer from its thickness and material — the key figure for verifying a wall, attic, or floor meets its thermal performance target.
Retaining Wall Block Calculator
Find how many blocks you need for a retaining wall from its length and height — a row-by-row calculation for straight, unbattered wall designs.
Wallpaper Calculator
Find how many wallpaper rolls you need for a room's wall area — using usable coverage per roll to account for pattern-matching waste.
