How much extra tile should I buy?

Add 10% extra for simple rectangular rooms with straight layouts. Add 15-20% for diagonal patterns, herringbone, or rooms with many cuts. Buy extra tiles from the same lot for color consistency and future repairs.

What tile sizes work best for different spaces?

Small tiles (2-4 inches) for small bathrooms and detailed work, Medium (6-12 inches) for most rooms, Large format (12+ inches) for open spaces and modern looks. Larger tiles mean fewer grout lines but may need more precise floor leveling.

How do I calculate tile for walls vs. floors?

Same calculation method: measure area and divide by tile size. For walls, measure height and width, subtract large openings. Remember wall tile often uses different sizes and styles than floor tile.

What's the difference between glazed and unglazed tile?

Glazed tiles have a glass-like coating (water resistant, easier to clean, more color options). Unglazed tiles show the natural material (better slip resistance, more porous, need sealing). Choose based on location and needs.

How to Use This Calculator

Measure the Surface Area

Measure length and width of the floor or wall in feet or inches. For walls, measure height and width. Calculate square footage by multiplying length × width.

Choose Tile Size

Note your tile dimensions (e.g., 12" × 12", 18" × 18", or 6" × 24"). Enter these dimensions to calculate how many tiles fit in your space.

Calculate with Pattern Factor

Enter your measurements and tile size. Select your pattern (straight, diagonal, herringbone) as this affects waste. The calculator shows total tiles needed.

Add Waste and Order

The calculator includes waste factor. Verify the total, round up to nearest box (tiles sold in boxes). Order all tiles from same lot/batch for color consistency. Don't forget grout, spacers, and thinset.
