This calculator helps you plan tile layouts for floors and walls, estimating the number of tiles needed for your renovation project.
It accounts for room dimensions, tile size, and waste factors to give you a practical breakdown for DIYers or contractors.
Use it to budget materials accurately and avoid over-ordering for your home improvement job.

How to Use This Tool
Enter the length and width of your room in feet, then specify the tile dimensions in inches. Choose your layout pattern from the dropdown, and set a waste factor (typically 10% for straight layouts, higher for complex patterns). Click Calculate to see a detailed breakdown of tiles needed, room area, and box estimates.
Formula and Logic
The tool calculates room area (length × width) and divides it by the area of a single tile (converted to square feet). For diagonal or herringbone patterns, it applies a multiplier (15% or 20% extra) to account for increased cutting waste. The waste factor is then added, and results are rounded up to whole tiles and boxes.
Practical Notes
- For outdoor tiles or high-traffic areas, consider increasing the waste factor to 15-20% due to breakage and cuts.
- Diagonal and herringbone patterns require more tiles due to angled cuts; order extra to avoid shortages.
- Check tile box quantities—some brands sell 8-15 tiles per box, so adjust box estimates accordingly.
- Seasonal considerations: In cold climates, allow tiles to acclimate indoors for 24-48 hours before installation to prevent cracking.
- Tool requirements: Use a wet saw for clean cuts on ceramic or porcelain tiles; a tile cutter may suffice for softer materials.
Why This Tool Is Useful
This calculator helps homeowners and contractors avoid over-ordering or under-ordering tiles, saving money and reducing waste. It provides a clear breakdown for budgeting and planning, making renovation projects more efficient and less stressful.
Frequently Asked Questions
What if my room has obstacles like cabinets or vents?
Subtract the area of obstacles from the total room area before calculating. For example, measure the obstacle area in square feet and deduct it from the room area input.
How accurate is the waste factor?
The waste factor is an estimate; actual waste depends on room shape, tile size, and installer skill. Start with 10% for simple layouts and adjust based on experience.
Can I use this for wall tiles?
Yes, but note that wall tiles are often thinner and may have different coverage. Measure the wall area similarly and consider vertical layout patterns.
Additional Guidance
For large projects, consult a professional installer to verify measurements and pattern choices. Always buy tiles from the same batch to ensure color consistency. Keep extra tiles for future repairs or replacements.
