Two quick counts: boxes of tile for an area, gallons of paint for a wall. Counted in your browser.
The finishes start with common values: 1,44 m² per box of 60 × 60 cm porcelain, 30 m² per gallon and coat of vinyl paint with two coats, 2,98 m² per drywall sheet of 1,22 × 2,44 m, baseboard in 2,4 m pieces.
Replace them with the label of the product you choose. Add about 10 % waste for straight layouts and about 15 % for diagonal layouts or rooms with many cuts.
Buy all the tiles of one finish from the same batch, with the same shade and caliber printed on the box, and keep a few spare pieces for repairs.
Paint from different batches can differ slightly in colour: buy it together, or mix the cans before starting.
