Frequently Asked Questions

How accurate is the estimate?

The calculator provides a planning estimate based on your measurements, depth, and bag size. Actual needs may vary with surface preparation, compaction and pebble shape. Ordering one extra bag can help account for these variables.

What depth should I use?

Depth varies depending on the type of pebbles (their size and application). See the coverage & depth guide above for a quick general rule. Heavier traffic or softer soil may need a little more.

Can I use this for gravel?

Yes - the volume math is the same for gravel. Select the closest product/bag size and enter your dimensions.

How do I measure a curved project area?

Sketch the project and split it into simple shapes (rectangles, triangles, or semicircles). Calculate each area and add them together. For complex shapes, measure a grid (e.g., 1 m squares) and count filled squares.

What if my bag size is different?

Our tool factors in the selected bag size automatically. If you’re unsure, check the product page or contact us for help.

Will I need extra for topping up later?

Pebbles settle over time, especially on fresh soil. Keep 5–10% extra for maintenance or plan a light top-up after a few months.

Does the base affect coverage?

Yes. A compacted base or geotextile over soil reduces sinkage and improves yield. Over hard paving, you can often use a slightly shallower depth.
