What are you working out?
Choose a calculation. Every tool includes its units, formula and a worked example.
Floor Area
A rectangular floor area is the starting point for many material takeoffs.
Open calculator ↗Room Perimeter
Room perimeter supports planning for skirting, trim and wall runs.
Open calculator ↗Wall Area
Net wall area removes doors and windows from a simple rectangular elevation.
Open calculator ↗Whole-Room Wall Area
Four wall faces can be estimated from room perimeter and uniform height.
Open calculator ↗Paint Quantity
Paint volume connects surface area, coat count and product coverage.
Open calculator ↗Paint Can Count
Whole-can purchasing rounds a calculated volume up to the next available pack.
Open calculator ↗Tile Quantity
A tile takeoff divides the ordered coverage by the face area of one tile.
Open calculator ↗Tile Box Count
Packaging coverage converts a material-area estimate into purchasable boxes.
Open calculator ↗Laminate Pack Count
Flooring is usually purchased in complete packs rather than exact square metres.
Open calculator ↗Wallpaper Strip Count
Counting full-height strips is the first stage of a wallpaper estimate.
Open calculator ↗Wallpaper Roll Count
Usable full strips per roll determine the number of complete wallpaper rolls.
Open calculator ↗Skirting Board Count
A linear takeoff converts trim length into stock board quantities.
Open calculator ↗Rectangular Slab Volume
A uniform slab volume follows its plan area multiplied by thickness.
Open calculator ↗Concrete Bag Count
Bagged material yield translates a volume requirement into a whole-bag order.
Open calculator ↗Circular Pad Volume
A circular pad uses disk area times uniform depth.
Open calculator ↗Trench Excavation Volume
A rectangular trench volume estimates the in-place material to remove.
Open calculator ↗Gravel Volume
A gravel layer is estimated as area times settled depth.
Open calculator ↗Aggregate Mass
Bulk density converts a volume estimate into a mass-based order.
Open calculator ↗Soil Expansion
Excavated material often occupies a larger loose volume than it did in place.
Open calculator ↗Haul Load Count
A volume-based haul count rounds up partial final loads.
Open calculator ↗Rectangular Paver Count
Paver face area provides a basic count for a regular surface.
Open calculator ↗Border Stone Count
A straight edging run can be converted into repeated stone units.
Open calculator ↗Fence Panel Count
A modular fence run is divided into panel-sized spans.
Open calculator ↗Fence Post Count
One isolated straight run needs a post at both ends and one between adjacent panels.
Open calculator ↗Deck Board Count
Parallel boards and their gaps determine how many fit across a deck.
Open calculator ↗Deck Linear Metres
Multiplying board count by run length estimates the total linear material.
Open calculator ↗Sheet Material Count
Sheet coverage gives a quick purchasing estimate for a surface.
Open calculator ↗Stud Position Count
Regular spacing plus both endpoints gives a simple count along one run.
Open calculator ↗Insulation Pack Count
Pack coverage converts a measured area into purchasable insulation quantities.
Open calculator ↗Roof Slope Length
A straight slope forms the hypotenuse of a triangle with horizontal run and rise.
Open calculator ↗Roof Pitch Angle
Pitch angle converts a rise-to-run ratio into an angular description.
Open calculator ↗Single Roof Plane Area
A rectangular roof plane uses its actual sloping dimension, rather than its horizontal projection.
Open calculator ↗Slope Percent
Slope percent expresses rise per one hundred units of horizontal run.
Open calculator ↗Ramp Surface Length
A straight ramp surface is longer than its horizontal projection.
Open calculator ↗Rise per Step
Dividing a total height into equal rises provides a preliminary stair dimension.
Open calculator ↗Board Volume
Timber volume follows the product of actual dimensions and piece count.
Open calculator ↗Board Feet
A board foot is a lumber volume equal to one square foot at one inch thick.
Open calculator ↗Material Subtotal
A quantity takeoff becomes a base estimate when multiplied by a quoted unit price.
Open calculator ↗Waste-Adjusted Quantity
An explicit percentage allowance separates measured need from purchasing overhead.
Open calculator ↗Labour Hours
A production rate links task quantity to estimated work time.
Open calculator ↗Crew Duration
A simple crew model distributes person-hours across workers and working days.
Open calculator ↗Waste Skip Count
Container volume provides a first estimate of waste collection needs.
Open calculator ↗Joint Sealant Volume
A rectangular joint cross-section times its length estimates sealant volume.
Open calculator ↗Sealant Cartridge Count
Total sealant demand is rounded up to whole cartridges.
Open calculator ↗Grout Joint Volume
Known joint length and cross-section give a direct grout-volume estimate.
Open calculator ↗Material Coverage Rate
Measured coverage from a trial area can improve later quantity estimates.
Open calculator ↗Metres to Feet
The international foot is exactly 0.3048 metres.
Open calculator ↗Square Metres to Square Feet
Area conversion squares the length conversion factor.
Open calculator ↗Cubic Metres to Cubic Yards
Volume conversion cubes the exact yard-to-metre factor.
Open calculator ↗Inches to Millimetres
The international inch equals exactly 25.4 millimetres.
