Picking out new tiles can be tons of fun, but one of the many questions you’ll have to ask is: How much tile do I need? The answer depends on the square footage of your space and the size of the tiles. This tile calculator will help you determine the correct number of tiles to order based on the following factors.
Quick Reference: Tile Estimates by Project Size
You’ll need to consider a few factors when deciding how much tile to order, including the surface area of the project and the size of the tiles.
Before we get into formulas, here’s a quick overview of how many 4”x 4" tiles you might need for common project sizes. These numbers assume you’re using 1/8-inch grout lines (we’ll explain more about that below) and include a 10% overage to account for cutting, breakage, and future repairs.
| Project Size (in Square Feet) | Number of Tiles Required |
|---|---|
| 25 | 234 |
| 50 | 467 |
| 75 | 699 |
| 100 | 932 |
| 150 | 1,397 |
| 200 | 1,863 |
| 250 | 2,328 |
Calculating How Much Tile You Need
Before you can calculate how many tiles to buy, you’ll need to know the size of your project and the dimensions of your tiles. Then, you can use the following formula to determine the correct number of tiles:
Number of Tiles Needed = (Project Size (in Square Inches) / Tile Size (in Square Inches)) x 1.1

To calculate the correct amount of tile for your project, you’ll have to take a few measurements. Here’s how to do it.
How to Measure Square Feet for Tile
There are different ways to measure square footage for tile installations, depending on the layout of your space.
For a square or rectangular area, you’ll simply multiply the length and width to get its square footage.
If you’re measuring a circular area, measure the diameter of the circle and divide it in half. This will give you the radius of the circle, which you’ll then multiply by itself (to square it). Finally, multiply the squared radius by 3.14 to get the square footage of the tiled area.
For a triangular area, measure the base and divide it in half. Then, measure the height by extending the line from the base to the furthest point of the triangle. Multiply those two numbers to find the space’s square footage.
How to Measure Tile Sizes
Tiles come in various sizes, ranging from a quarter-inch to several feet in diameter. When shopping for tile, be sure to note the dimensions, since they’ll directly impact how many tiles you need to buy.
After you’ve chosen a tile size, add the size of the grout lines to the length and width of each tile. For example, if you’re using 4 x 4-inch tiles and 1/8-inch grout lines, the total size of each tile would be 4 1/8 x 4 1/8 inches. Then, multiply the length and width to get each tile’s area (in this example, it would be 17.02 inches).
Who to Hire for Tile Installation
Whether you’re retiling a shower, installing a new tile floor, or adding a backsplash, hiring a tile contractor is your best bet. Here’s why:
They have the expertise, skills, and tools to perform the job safely and successfully.
They work faster than the average DIYer.
They know how to minimize the risk of future problems with your tile, such as leaks and mold.
They can help you choose and order the right tiles and materials for your project.
Frequently Asked Questions
If you hire a professional to lay tile, you can expect to pay $3 to $15 per square foot for labor. For a 100-square-foot tiling project, that would equal $30 to $150 in labor. These costs may increase if you need extra services (such as tile removal, wall repair, or waterproofing). For example, tile removal costs an additional $2 to $7 per square foot.
On average, tiling a shower costs between $1,800 and $5,000, with most people paying around $2,700. The price of this project depends on multiple factors, including the kind of tile you choose, the size of your shower, and labor rates in your area. If you decide to tile your own shower (instead of hiring a professional), it’ll likely cost $800 to $1,400.
