How to Use the Tile Calculator
Our free tile calculator helps you determine exactly how many tiles you need for your flooring or wall tiling project. Simply enter your room dimensions and tile size to get an instant calculation including waste allowance.
The calculator automatically adds a waste percentage (typically 10-15%) to account for cuts, breakage, and future repairs. This ensures you purchase enough tiles to complete your project without running short.
Why Add Waste Percentage?
Cutting & Trimming
Tiles at edges and corners need to be cut to fit, resulting in unusable pieces
Breakage
Some tiles may break during cutting, installation, or transportation
Future Repairs
Keep extra tiles for future repairs - same batch tiles may not be available later
Pattern Matching
Complex patterns or designs may require additional tiles to align properly
Recommended Waste Percentages
10% - Standard Installation
For simple layouts with straight lines and minimal cuts. Good for experienced installers working with standard rectangular tiles.
15% - Complex Layouts
For diagonal patterns, herringbone layouts, or rooms with many corners and obstacles. Recommended for most DIY projects.
20%+ - Intricate Designs
For elaborate patterns, mosaics, or when working with fragile tiles. Also recommended for first-time installers or irregularly shaped rooms.
Frequently Asked Questions
How accurate is this tile calculator?
The calculator provides accurate estimates based on the dimensions you enter. However, always verify measurements on-site and consult with a professional installer for complex projects.
Should I round up the number of tiles?
The calculator automatically rounds up and includes waste percentage. However, it's always safer to purchase a few extra tiles, especially if the pattern or color might be discontinued.
Can I use this for wall tiles?
Yes! This calculator works for both floor and wall tiles. Just enter the wall dimensions instead of floor dimensions. Consider adding extra waste (15-20%) for wall installations due to more complex cutting around fixtures.
What if my room isn't perfectly rectangular?
For irregularly shaped rooms, divide the space into rectangular sections, calculate tiles for each section separately, then add them together. Increase the waste percentage to 15-20% for irregular spaces.
How do I calculate for diagonal tile layouts?
Use the same calculator but increase the waste percentage to at least 15-20%. Diagonal layouts require more cuts and result in more waste, so the extra percentage is essential.
