How to Use the Gravel & Sand Calculator
Whether you're building a new driveway or preparing a sub-base for a patio, our gravel and sand calculator ensures you order the right amount of aggregate. Start by entering the length and width of the area in meters.
Next, enter the desired depth of the gravel or sand layer—standard sub-bases are usually 50mm to 150mm deep. If you have a price per ton or per cubic meter, enter it for a total cost estimate. Click "Calculate Now" to see the total volume and the estimated weight in tons.
Pro Tips for Aggregate Projects
Compaction Factor
Aggregate settles and compacts when rolled or tamped. Always add 20% to your volume estimate to account for this compaction, ensuring your final layer reaches the required depth.
Use a Weed Barrier
Before spreading gravel or sand, lay down a heavy-duty geotextile fabric. This prevents weeds from growing through and keeps the aggregate from sinking into the soil over time.
Frequently Asked Questions
How much does a cubic meter of gravel weigh?
A cubic meter of standard crushed gravel typically weighs between 1.5 and 1.7 tons, depending on the specific stone size and current moisture content.
What is the best gravel for a driveway?
"MOT Type 1" or "Crushed Stone Grade 2" is the industry standard for driveway sub-bases due to its excellent load-bearing and drainage properties.
How deep should a gravel driveway be?
A standard gravel driveway should have a sub-base of at least 100mm to 150mm of compacted aggregate, topped with a 50mm layer of decorative surface gravel.
