What this tile calculator estimates
The calculator estimates base area, layout waste, order area, tile count, boxes, thinset, grout, and a material total. It works for floor tile, wall tile, showers, and backsplashes.
What to verify before buying tile
Confirm substrate condition, waterproofing, transitions, edge profiles, trim pieces, batch numbers, lead time, return policy, and whether the installer wants extra attic or garage stock for repairs.
Common questions
How much extra tile should I buy?
Straight layouts often need about 10% waste. Diagonal, herringbone, niches, borders, and small cuts often need 15% to 20% or more.
Does this include labor?
No. It estimates materials. Labor depends on demolition, substrate prep, waterproofing, leveling, pattern complexity, tile size, cuts, and local contractor minimums.
Can I use metric measurements?
Yes. Switch to metric to enter meters, centimeters, square meters, and per-square-meter pricing.
