Tile Calculator
Calculate tiles needed for flooring project by room size. Estimate number of tiles, boxes, grout, and waste factor for bathroom, kitchen, or floor tiling.
Plan tile quantity and budget
Enter room length and width, tile size, grout line width, and a waste percentage. The tool shows area, tile count, optional boxes to order, and rough material cost in the currency you select. Split complex jobs by room and add the totals.
Pro tip: Raise the waste % for herringbone, diagonal runs, or lots of niches. Keep a few leftover tiles for repairs. Full-room or whole-home budgets in USD: Renovation Cost Calculator. More Q&A (waste, grout lines, boxes) is in the Frequently Asked Questions section below the calculator on this page.

Understanding Tile Installation
Proper tile installation requires accurate planning, quality materials, and attention to detail. Understanding the basics helps ensure a successful project.
Key Installation Steps
- Surface Preparation: Clean, level, and stable surface is essential
- Layout Planning: Plan tile placement to minimize cuts and waste
- Adhesive Application: Use appropriate adhesive for tile type and location
- Tile Setting: Set tiles with consistent spacing using spacers
- Grouting: Fill joints after adhesive cures (24-48 hours)
- Sealing: Seal natural stone and porous tiles
Tile Types and Uses
- Ceramic: Affordable, versatile, good for most areas
- Porcelain: Durable, low water absorption, great for wet areas
- Natural Stone: Beautiful but requires sealing and maintenance
- Glass: Decorative, great for backsplashes
- Mosaic: Small tiles, perfect for accents and curved surfaces
