How do I work out how much flooring I need?

To calculate how much flooring you need, start by measuring the length and width of each room in metres. Multiply the two numbers to get the area in square metres (m²).

For example:
Room size: 4m x 5m = 20m²

 
Then add extra for wastage:

• Straight plank flooring: Add 5–10%
• Herringbone, chevron, or diagonal patterns: Add 10–15%

This covers offcuts, mistakes, and future repairs.

 
Quick Tips:

• Round up to the nearest whole pack when ordering
• Measure odd-shaped rooms in sections and add them together
• Always double-check if product listings are per pack or per m²

Getting the right amount avoids delays, mismatched batches, and costly reorders. If you’re unsure, most flooring suppliers (like us!) are happy to help calculate based on your room plans.
