Tile Quantity Calculator

This Tile Quantity Calculator helps you estimate how many tiles are needed based on tile dimensions and the total area to be covered.


How to Use

  • Select the unit: Centimeters or Inches.
  • Enter the tile’s width and length.
  • Enter the grout joint width.
  • Enter the total area to cover in square centimeters, or convert it accordingly if using inches.
  • Adjust the wastage percentage if needed.
  • Click "Calculate" to see the number of tiles required.

Tile Quantity Calculator

This tool helps you figure out how many tiles you’ll need to cover a floor or wall area. It’s simple and easy to use—no math required.


How the Tool Works

The calculator takes your tile size, grout space (gap between tiles), total area to be covered, and adds in wastage for broken or cut tiles. Here’s how it works step by step:

  1. Choose units: You can pick either centimeters or inches.
  2. Enter tile dimensions: Type the width and length of your tiles (in cm or inches).
  3. Add grout space: Enter how wide you want the joint to be between tiles—this affects how many tiles fit in one area.
  4. Input total area: This is the size of the surface you want to cover, in square centimeters or square feet depending on your unit choice.
  5. Set wastage percentage: Most people add 10% extra for cuts and breakages—you can adjust this up to higher values if needed.

Then click “Calculate” to see how many tiles are required.


Inputs You Can Use

  • Tile width – the size of your tile in centimeters or inches
  • Tile length – same as above, but for length
  • Grout joint width – how thick you want the gap between tiles to be (optional)
  • Total area to cover – this is where you enter the size of the room or wall (in cm² or ft²)
  • Wastage percentage – default is 10%, but you can change it to match your project

How It Calculates

The tool:

  • Adds grout space around each tile: so if a tile is 20cm wide and the grout is 0.5cm, then one tile takes up (20 + 0.5) = 20.5 cm in width.
  • Multiplies that by the length to get total area per tile including grout.
  • Divides your total area by this tile area to find how many tiles you need.
  • Adds extra for wastage—like if you expect some tiles to be cut or broken.

How to Use This Tool

Here’s a quick guide:

  • Click “Centimeters” or “Inches” to switch units.
  • Enter your tile size (width and length).
  • Type in the grout width if you want it included.
  • Enter total area, using either cm² or ft²—just make sure it matches the unit you selected.
  • Set wastage percentage (10% is common for most projects).
  • Click “Calculate” to see your result.

Tip: Always round up. Even small errors can lead to missing tiles at the end of a project.


Why Use This Calculator?

It saves time and avoids mistakes:

  • No more guessing how many tiles you need.
  • You won’t run out mid-project or buy too much.
  • It’s great for DIY projects, renovations, or professional work.

Whether you’re tiling a bathroom, kitchen, patio, or wall—this tool helps you plan properly.
