Construction Calculators
Work out what a job needs before you buy it: concrete volume and bags, tiles, flooring, roofing, fencing and mulch — each with the waste allowance shown separately from the net quantity.
- Concrete CalculatorSlab volume, bags to buy, waste allowance.
- Square Footage CalculatorEnter the length and width to get the area in square feet, square yards and square metres.
- Tile CalculatorEnter the area and your tile size to see the tiles needed, the boxes to buy and the spares left over.
- Flooring CalculatorEnter the room area and the coverage printed on the box to see how many boxes to buy.
- Roofing CalculatorEnter the footprint and the pitch to get the true sloped area, in square feet and in squares.
- Fence CalculatorEnter the run and your spacing to see the posts, sections, rails and pickets.
- Mulch CalculatorEnter the bed area and the depth you want to see the volume and the bags to buy.
- Brick CalculatorEnter the wall, the brick and the joint. Openings come off the area, and the order is shown apart from the net count.
- Gravel CalculatorEnter the area and the depth you want when it is finished and rolled. The answer is what to order, not what fits in the hole.
- Paint CalculatorEnter the room and the coverage printed on the tin. Openings come off, coats multiply, and whole tins are what you buy.
