LineCalc: Plan Construction

Know exactly how much to buy before you start any renovation — paint, wallpaper, flooring, tiles, or plaster.

Paint calculator: Enter your wall and ceiling dimensions, subtract windows and doors, choose the number of coats and coverage per square metre, and get the exact volume of paint you need to buy.

Wallpaper calculator: Calculate the number of rolls based on wall area and roll size, so you order the right amount the first time.

Flooring calculator: Work out how much laminate, tile, or vinyl flooring you need based on room area, with extra built in for cutting waste.

Tile calculator: For walls or floors — factor in tile size and grout line width, and get the exact number of tiles and packs to buy.

Screed & plaster calculator: Calculate the volume of mix you need based on area and layer thickness, so you mix exactly what the job requires.

Time & budget estimate: Get an estimate of labour hours for the job, plus an approximate material cost based on the price per unit you enter.

Save your projects: Group calculations by room or apartment, and keep a history of notes for every project as it develops.

Unit converter: Switch between metres and feet, litres and gallons — built for different markets and different habits.

Whether you're renovating one room or planning an entire apartment, this app turns guesswork into exact numbers — so you buy the right amount, every time.
