How to measure your area

Rectangles & Squares

Measure the longest length and width edge to edge.

Area = Length × Width

Example: 6 m × 4 m = 24 m²

Circles

Measure the full diameter (edge to opposite edge through the centre).

Area = π × (Diameter ÷ 2)2

Use π ≈ 3.142

Irregular Shapes

Break into simple shapes (rectangles/triangles/circles), work out each area, then add together.

Sketch it and label each section—this reduces mistakes.

Depth / Coverage

  • Keep depth consistent across the whole area.
  • Allow extra for edges, curves and containment borders.
  • Soft-fall zones or play areas may require specific depths.

Important

All calculations are approximations. Real-world usage can vary due to factors outside our control, including:

  • Depth fluctuations across the area (uneven ground, dips/high spots).
  • Irregular shapes, cuts and edge trims leading to off-cuts/waste.
  • Base condition, compaction and settlement over time.
  • Moisture content and normal batch variation of materials.
  • Human measuring error or rounding differences.

If you’re unsure, add a small contingency or contact us for advice.

SBR, EPDM and Resin are availabine in 25KG only due to restrictions in manufacturing. We recommend a minimum area of 5 square meters when looking at the resin bound kits. All measurements are done at the industry standard of 50mm depth, adjust amounts accordingly.
