How do I calculate tiles needed for a floor?

Divide floor area by tile area (including grout gap). For 200 sq ft floor with 12×12 inch tiles (1 sq ft each): 200 tiles needed. Add 10% for cuts and waste, so order 220 tiles.

How much extra tile should I order for waste?

Order 10% extra for simple rectangular rooms with straight layouts. Order 15% for diagonal patterns or rooms with many cuts. Order 20% for complex patterns like herringbone. Keep some extras for future repairs.

How do I account for grout lines in tile calculations?

Add grout width to tile dimensions. For 12×12 inch tiles with 1/8" grout: effective tile = 12.125×12.125 inches = 1.02 sq ft. The calculator automatically adjusts for grout spacing.

What tile size is best for my room?

Larger tiles (18-24") make rooms look bigger but require flatter floors. Small rooms benefit from medium tiles (12×12"). Small tiles (4×4") work for accent areas. The calculator helps visualize different sizes.

How do I calculate tile for walls?

Multiply wall height × width, then subtract openings (doors, windows). For a 10×8 ft wall with a 3×4 ft window: (80 - 12) = 68 sq ft of tiles needed. The calculator handles wall calculations.

What is the difference between tile patterns and their waste?

Straight/stack bond: 10% waste, easiest installation. Brick/running bond: 12% waste, offset rows. Diagonal: 15% waste, angled cuts. Herringbone: 15-20% waste, many precise cuts required.
