Tiling Calculator
What is a Tiles Calculator?
A tiles calculator helps you quickly figure out how many tiles you need for your project. By entering the area size, tile dimensions, and an allowance for wastage, you get an accurate estimate in seconds. This simple tool saves time, reduces waste, and ensures your project stays on track, making it ideal for any tiling job.
Tile Calculation Formula
The fundamental formula for calculating tile requirements is:
Required Tiles = (Area to be Tiled + Wastage %) ÷ Coverage per Tile Pack

Why Use a Tiles Calculator?
Using a tiles calculator offers several advantages:
- Accuracy: Ensures precise calculations based on the area and tile size.
- Cost Effective: Avoids overordering or underordering tiles.
- Time Saving: Simplifies planning and eliminates guesswork.
- Professional Results: Helps achieve a polished, uniform look.
- Reduce waste, supporting environmental sustainability
How to Use Our Tiles Calculator?
Here’s a step-by-step guide:
- Measure the Area: Use a tape measure to find the length and width of the area in meters or feet.
- Enter Tile Dimensions: Input the dimensions of the tile you plan to use.
- Account for Wastage: Add a percentage (usually 10-15%) to account for cutting and breakages.
- Get the Result: The calculator provides the total number of tiles you need.
Key Factors to Consider When Calculating Tiles
1. Tile Size
The size of your tiles greatly influences how many you’ll need. Smaller tiles, such as mosaics, are perfect for intricate designs but require more grout and effort to install. Larger tiles cover areas faster with fewer grout lines, giving a clean and spacious appearance. Choose a size that complements your design and suits the area being tiled.
2. Room Shape and Obstructions
Every room is unique. Irregularly shaped spaces or those with features like alcoves, columns, or fixtures demand extra attention. Measure each section separately and plan for the additional cuts needed to fit tiles neatly. Creating a detailed layout can help visualise the design and minimise errors.
3. Include a Wastage Allowance
Always factor in a wastage buffer. It’s standard to order 5%-10% extra tiles to account for cutting, mistakes, or future repairs. For more complex patterns, such as herringbone or diagonal layouts, increase this to 15%-20% as these designs involve more precise cuts. Keeping extra tiles on hand ensures consistency if repairs are needed later.
Tile Calculator Example
Area Dimensions (meters) | Tile Size (cm) | Wastage (%) | Total Tiles Needed |
---|---|---|---|
3 x 4 | 30 x 30 | 10 | 45 |
5 x 6 | 60 x 60 | 15 | 85 |
2 x 2 | 45 x 45 | 10 | 25 |
Advantages of Different Tile Sizes
Tile Size | Best Suited For | Advantages |
---|---|---|
Small (e.g., 10×10) | Backsplashes, mosaics | Intricate designs, easy to fit |
Medium (e.g., 30×30) | Bathrooms, kitchens | Versatile, standard look |
Large (e.g., 60×60) | Living rooms, large spaces | Minimal grout lines, modern |
Common Mistakes to Avoid When Using a Tiles Calculator
- Ignoring Wastage: Always include a buffer for wastage.
- Overlooking Obstructions: Remember to measure around fixtures and fittings.
- Wrong Units: Ensure all measurements are in the same unit (e.g., meters or feet).
Popular Tile Patterns and Their Impact on Calculations
The way you lay tiles can affect how many you need. Popular patterns include:
Pattern Type | Additional Tiles Needed |
---|---|
Straight lay | 10% extra |
Diagonal | 15% extra |
Herringbone | 20% extra |
1. Straight Lay
A simple, clean look where tiles are laid in straight lines. Minimal wastage.
2. Diagonal Lay
Tiles are set at a 45-degree angle. Requires more cutting and extra tiles.
3. Herringbone
A trendy zigzag pattern that adds visual interest. Higher wastage due to cuts.
