How do I calculate how many tiles I need?
To calculate how many tiles you need, simply enter your room dimensions and tile size into our calculator above. Measure the length and width of your space, then input these values along with your tile dimensions. Our calculator will automatically determine the total number of tiles needed, including waste allowance for cuts and breakage.
How much extra tile should I buy for cuts and waste?
It's recommended to buy 10% to 15% more tile than your measured area to account for cuts, mistakes, and future repairs. For complicated layouts or diagonal patterns, you may want to increase that to 20%.
What's the best tile size?
The best tile size depends on your space. Larger tiles (like 12x24) are popular for open areas such as living rooms and kitchens, while smaller tiles (like mosaics) are often used in bathrooms, backsplashes, or showers. A good rule of thumb: larger rooms can handle larger tiles.
Can I use large tiles in small rooms?
Yes, large tiles can be used in small rooms and may even make the space appear larger due to fewer grout lines. Just make sure the subfloor is level, as larger tiles require a flatter surface for proper installation.
How many tiles are in a box?
The number of tiles in a box varies depending on the tile size, thickness, and manufacturer. Always check the product label or ask your supplier for exact coverage information.
Should I install tiles myself or hire a professional?
While DIY tile installation is possible for basic projects, we strongly recommend consulting with a professional tile installer first. Professionals can help you avoid costly mistakes, ensure proper waterproofing in wet areas, and handle complex layouts or large-format tiles. Even if you decide to DIY, getting professional advice upfront can save you time, money, and frustration.
