Why Waste Percentage Matters

Many people underestimate the importance of adding extra tiles for waste. During installation, tiles often need cutting around:

• Corners
• Electrical outlets
• Pipes
• Windows
• Cabinets

Some tiles may also:

• Break during installation
• Arrive damaged
• Need replacement later

Adding a waste percentage helps avoid running out of tiles mid-project.

Recommended Waste Percentage

The ideal waste percentage depends on the complexity of the project.

Suggested Guidelines

• Straight layout: 5% to 10%
• Diagonal layout: 10% to 15%
• Complex patterns: 15% or more

Ordering extra tiles can also help with future repairs and replacements.

Tips for Accurate Tile Calculations

To get the best results, follow these practical tips:

Measure Carefully

Always double-check wall dimensions before entering values.

Use Consistent Units

Make sure all measurements use the same unit system.

Include Obstacles

Subtract large windows or doors if they significantly reduce tile coverage area.

Buy Extra Tiles

It is safer to order a few additional tiles beyond the calculated amount.

Consider Tile Pattern

Patterns like herringbone or diagonal layouts usually create more waste.

Save Leftover Tiles

Extra tiles can be useful for future repairs.
