Pebbles Calculator
Use our calculator to quickly estimate the quantity you need. Enter the area of your project (or exact measurements: length, width, depth) and the tool will calculate coverage in cubic metres and convert that to bags based on your selected pebble and the chosen depth. It’s a handy calculator that helps you plan a consistent, professional finish - without over- or under-ordering.
How to use the calculator
- Choose your pebble.
- Enter length × width of the area (or select “project area” and type your total).
- Review the result in cubic metres converted to recommended bag quantity.
- Tip: For irregular shapes, break the space into simple rectangles or circles and add them together.

These recommendations are based on a depth of 50mm.
Coverage & depth guide
As a general rule, coverage can vary depending on pebble size and area:
- Smaller pebbles: Approx. 30mm depth
- Larger pebbles: Approx. 50–70 mm depth
Top-up over existing gravel: 20–30 mm. On soft soil, use a weed mat and compacted base to reduce sinkage and improve coverage.
Measuring & unit tips
- Need imperial? Measure in feet/inches, then convert to metres (1 ft = 0.3048 m; 1 in = 25.4 mm).
- For paving borders or a narrow decorative border, measure linear run and multiply by the strip width and depth to find volume.
- For pathways, allow extra for edging and to cover high spots after raking.
Whether it’s a garden bed, feature area, or decorative border, plan with confidence and avoid over or under-ordering your Tuscan Path pebbles - saving time, money, and unnecessary effort.
