Paint

The right colour, the right amount

Give the Paint calculator your wall area and finish and it returns gallons by coat — plus primer, trim paint and how many rollers you'll get through. Match the swatch, not the guess, and skip the second trip to the store.

Flooring

Down to the last plank

Room dimensions become boxes of laminate, vinyl or parquet — with underlay, trim and a cutting allowance built in. So the final row lands flush and you're never one board short with the store already closed.

Waste allowance

A practical allowance for cuts and waste

Choose a waste percentage that suits the job. Renovimo applies it before rounding up to complete cans, boxes, sheets, bags or rolls, helping you avoid both a short order and unnecessary surplus.

The method

From measurements to a material list in three steps

Renovimo turns raw measurements into a bill of materials that already accounts for waste, coverage and overlap — the way a foreman would.

Try a calculator
  1. 01

    Enter your dimensions

    Measure walls, floors, ceilings, partitions or slabs in feet or metres. Add openings and excluded areas where the calculator supports them.

  2. 02

    Calculate a practical quantity

    Coverage rates, product sizes and a waste allowance turn your measurements into gallons, sheets, boxes, bags or rolls.

  3. 03

    Review the material list

    See the main material and supporting supplies such as primer, adhesive, grout, profiles, tape, screws or reinforcement.

Everything on the list

The right material, down to the tube of grout

Each result combines the main material with the supplies normally needed to install it: paint and rollers, tile adhesive and grout, drywall profiles and screws, concrete reinforcement, wallpaper paste or underlay tape.
