Floors & Walls
Surface projects live or die on coverage: how much tile, flooring, wallpaper, brick or bagged product your area actually needs. Every tool separates net area, allowance and whole purchasable units.

Open calculator →Choosing between these tools
Choose the tool for the quantity you need, then use its matching measurement mode. Check the product basis before turning area or volume into a purchase order.
Tile a room
Measure the usable surface and choose tile and grout-joint dimensions. Check adhesive coverage against the exact bag and trowel. Count tile, adhesive and grout separately.

Order masonry materials
Keep nominal modules and actual unit dimensions separate so mortar joints are counted once. A material count does not design a load-bearing wall.

Refresh walls and floors
Subtract exclusions where the form supports them. Match effective installed coverage to the product. Wallpaper uses full-strip matching, while flooring counts carton coverage.

Plan a slab or wall refresh
Estimate concrete volume or drywall sheets from measurements. Paint and primer use separate label coverage rates. These quantities do not specify structural or fire-rated assemblies.
