Tile Square Footage Calculator

Planning a tile project for your home, office, or construction site? Whether you're tiling a bathroom wall or laying floor tiles for a large room, knowing the exact tile square footage you need is essential to avoid overspending or running out mid-project. That’s why we’ve developed an easy-to-use Tile Square Footage Calculator. This tool takes the guesswork out of your tile measurements and helps you plan like a pro.

How to Calculate Tile Square Footage

Before using the calculator, it's helpful to understand the basic formula used to determine how many tiles are required. It’s a simple math-based method that gives you accurate results every time.

Step 1: Measure the Area

First, measure the length and width of the surface you want to tile, in feet or meters.

Example: If your room is 12 feet long and 10 feet wide:

Area = 12 × 10 = 120 square feet

Step 2: Determine Tile Size

Tiles come in various sizes. If your tile is measured in inches (like 12x12 inches), convert it to square feet:

Tile Area = (Tile Length in inches × Tile Width in inches) ÷ 144

So, a 12x12 inch tile: (12 × 12) ÷ 144 = 1 square foot

For tiles in centimeters or meters, convert accordingly: 1 square meter = 10.7639 square feet

Step 3: Calculate Number of Tiles Needed

Divide the total area by the area of a single tile:

Tiles Needed = Room Area ÷ Tile Area

Example: 120 ft² ÷ 1 ft² = 120 tiles

Step 4: Add Extra for Wastage

Add 10% to 15% more tiles to cover cutting, breakage, and layout errors:

Final Tile Quantity = Tiles Needed × 1.10 (for 10% waste)

120 × 1.10 = 132 tiles

How to Use the Tile Square Footage Calculator

Using our tile calculator is simple. Just follow these steps:

1. Enter the length and width of the area in feet or meters.
2. Enter the tile size (in inches or centimeters).
3. Choose the wastage percentage (usually 10% or 15%).
4. Click Calculate to get the exact number of tiles you need.

The calculator instantly displays:

• Total square footage
• Tile size in square feet or meters
• Total number of tiles required including wastage

It works for floor tiles, wall tiles, kitchen backsplash, bathroom tiles, and more.

Tile Calculation Example

Let’s say you have a 10x10 ft room and want to use 2x2 ft tiles.

Room Area = 10 × 10 = 100 ft²

Tile Area = 2 × 2 = 4 ft²

Tiles Needed = 100 ÷ 4 = 25

Add 10% waste = 25 × 1.10 = 27.5 ≈ 28 tiles

So, you’ll need 28 tiles of 2x2 ft for a 10x10 room.

Final Verdict

Our Tile Square Footage Calculator is built to make your tile planning process smooth and stress-free. Whether you’re working with square feet or square meters, 12x12 inch tiles or 60x60 cm tiles, this tool does the math for you. No more manual calculations or estimation errors. Just plug in your measurements and get your answer instantly.

It’s the ideal solution for DIY home renovators, interior designers, construction workers, and anyone looking to save time and money on tiling projects.

FAQs

How do you calculate square footage of tile?

Multiply the length and width of your room to get the area in square feet. Then divide that by the area of a single tile.

What is the 3/4/5 rule in tile laying?

This is a method to ensure your tile lines are perfectly square. Create a triangle with sides of 3 ft, 4 ft, and 5 ft. If the triangle closes perfectly, your lines are square.

How many 12x12 tiles do I need for 144 square feet?

A 12x12 tile is 1 square foot, so you need 144 tiles. Add 10% for waste: 144 × 1.10 = 158.4 ≈ 159 tiles.

How many 18x18 tiles do I need to cover 100 square feet?

An 18x18 tile = (18×18)/144 = 2.25 ft²

100 ÷ 2.25 = 44.44 → Add 10% waste = 49 tiles

Can I use this calculator for wall tiles too?

Yes! This tile calculator works for both wall and floor tile measurements.
