Why compare cost per m² rather than total cost?

Products come in different pack sizes and coverage rates. Cost per m² normalises prices so you can fairly compare different options.

How do I work out my coverage area?

Check the product label for coverage per bag or unit. Alternatively, use our Coverage Rate Calculator to work it out from depth and area.

Should I always choose the cheapest per m²?

Not necessarily. Quality, durability, and suitability matter too. A slightly more expensive option may last longer or look better.

How do I convert per m² to per sq ft?

Divide the per m² cost by 10.764 to get cost per square foot.

Why is cost per m² useful for comparing materials?

Different materials come in different bag sizes, weights, and prices. Cost per m² at the same depth gives a fair comparison between products and suppliers.

How We Calculate This

Cost per m² = Total Cost / Area in m². This gives a standardised unit price for comparison.

The comparison mode lets you evaluate two different materials side by side.

Cost per sq ft is provided for reference using the conversion factor of 10.764 sq ft per m².
