How much do I need? Paint, tile, flooring, concrete, mulch, wallpaper and BTU — quantity plus bags, tins and boxes.
Paint Calculator
Calculates litres or gallons and tins needed per room, minus doors and windows.
Solves: Too little paint stops the job; too much wastes money.
Tile Calculator
Calculates tiles and boxes needed, with 10% waste allowance.
Solves: Running out mid-floor risks a mismatched batch.
Flooring Calculator
Calculates packs of laminate, vinyl or wood per room size.
Solves: Flooring is sold by the pack, not by the square metre.
Concrete Calculator
Calculates cubic volume and bags needed for a slab or footing.
Solves: Concrete cannot be topped up easily once pouring starts.
Mulch Calculator
Calculates bags or bulk mulch needed by area and depth.
Solves: Garden beds need far more mulch than people guess.
Wallpaper Calculator
Calculates rolls needed, allowing for pattern repeat.
Solves: Pattern matching wastes paper most people forget to count.
BTU / Room Size Calculator
Recommends heater or AC size for a room.
Solves: Wrong-sized units waste energy and never feel comfortable.
Stair Calculator
Calculates riser height, tread and step count.
Solves: Stairs must meet comfort and code rules, not guesses.
Square Footage Calculator
Calculates area of rooms and irregular shapes.
Solves: Every other home calculation starts with a correct area.
Renovation Budget Planner
Totals project items into one budget with contingency.
Solves: Renovations overrun because small costs were never added up.
