Calculate how many tiles you need for floors, walls, backsplashes, and more. Get accurate estimates including waste factor, boxes needed, and total cost.
Proper tile estimation is crucial for budget planning and ensuring you have enough materials to complete your project. Always account for waste from cuts, breakage, and pattern matching.
For a 10×12 ft room (120 sq ft) using 12×12 inch tiles (1 sq ft each), you'd need 120 tiles exactly. With 10% waste, order 132 tiles. If tiles come 12 per box, buy 11 boxes (132 tiles total).
Tiles break during cutting, installation, or shipping. Edge tiles need cutting to fit. Complex layouts require more cuts. Patterns may require specific tile placement. A 10-20% waste factor ensures you have enough to complete the job without reordering (which might not match the batch).
Use the same square footage calculation, but increase the waste factor to 15-20%. Diagonal layouts require more edge cuts, creating more waste. Our calculator handles this automatically when you increase the waste percentage.
The calculation method is the same - it's based on square footage. However, wall tiles often have more cuts around outlets, switches, and edges, so consider using a slightly higher waste factor (15% instead of 10%) for wall installations.
Grout amount depends on tile size, grout joint width, and tile thickness. As a rough estimate: 12×12 tiles with 1/4" joints need about 2-3 lbs per 100 sq ft. Larger tiles need less grout. Check grout bag coverage charts for precise amounts.
Yes! Always keep 5-10 extra tiles. Tiles get discontinued, and new batches may have slight color variations. Having exact replacements from your original batch ensures perfect matches for future repairs or damage.
Break irregular rooms into rectangles and triangles. Calculate the area of each section separately, then add them together. For very complex shapes, sketch the room on graph paper and count squares, or use this calculator multiple times and sum the results.
Enter your custom tile dimensions in the calculator! Whether you have 13×13, 6×24, or any other size, just input the measurements. The calculator works with any tile size in either inches or centimeters.
“Saved me from buying too many tiles! The waste factor calculation was spot-on. I ordered exactly what I needed for my kitchen backsplash with just a few extras left over.”
“As a contractor, I use this daily to give clients accurate estimates. The cost breakdown helps with transparent pricing. Much faster than manual calculations!”
“Perfect for DIY projects! Helped me budget my bathroom remodel accurately. The grout estimate was super helpful too - I didn't have to guess!”
