CoverKit: Paint & Tile
Measure the walls, buy exactly enough paint, wallpaper or tile
Enter each wall's run and ceiling height, tap out the windows and doors, and CoverKit returns the gallons, rolls, or tile boxes plus grout to buy — with the safety buffer, the real formula, a per-room shopping list and a project total. Free, no install, no account.

What you can do in CoverKit: Paint & Tile on the web
Wall-by-wall, not a guessed average
Every wall keeps its own width × height and its own subtracted openings, so a room with a picture window and a room without do not come out the same.
Tap out windows and doors
Quick-add chips subtract a standard door (21 sq ft), a window (12 sq ft) or a big window (24 sq ft) — you never pay to cover glass.
Paint gallons for your coats
Net area × buffer × coats ÷ the coverage printed on your can, rounded up, priced per gallon — the formula is shown so you can check it.
Wallpaper rolls with pattern repeat
A 1.15× repeat adds 15% of waste before the rolls are counted, because a patterned paper never cuts to zero.
Tile boxes plus grout bags
Tile size in inches becomes tiles per square foot, tiles become boxes at your count-per-box, and the raw net area becomes bags of grout.
A shopping ticket for the whole job
Project totals, a cost-by-material donut, per-room line items, and a plain-text list you can copy or download for the store.
