One of the most common questions gardeners and landscapers ask is how much material they need for a project.

Ordering too little can delay progress, while ordering too much can increase costs and create unnecessary waste.

The easiest way to calculate volume is to measure the length, width, and desired depth of the area being covered. Multiplying these three measurements provides the cubic metre volume required.

As a general guide:

• Garden beds often require 50–100mm of compost.
• Mulch is typically applied at 50–100mm depth.
• New lawns may require 75–150mm of prepared soil.
• Soil improvement projects vary depending on existing soil conditions.

It’s also important to consider settlement and incorporation. Compost worked into existing soil will occupy less volume than compost spread across the surface as a mulch layer.

Using a volume calculator can provide a helpful estimate before ordering. Clyde Compost includes product-specific calculators across many of its soil, compost, mulch, and aggregate products to help customers plan their projects with confidence.

Taking a few minutes to calculate quantities accurately can save time, money, and additional deliveries.
