Enter your dimensions in feet or metres and calculate paint, tile, flooring, drywall, concrete, wallpaper, roofing, gravel, brick and trim. Renovimo includes openings, coverage rates and cutting waste so you can order a practical quantity for the job.
The toolkit
Choose a free material calculator
Estimate quantities, full packs and supporting materials before you buy, with metric and imperial measurements.
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.

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.
