Measuring Irregular Shapes

Divide irregular areas into overlapping rectangles, triangles, and circles. A typical garden might be: main lawn rectangle, minus a circular flower bed, plus a triangular corner border. Calculate each section and add or subtract as appropriate.

Why Accurate Area Matters

Lawn products (seed, fertiliser, treatments) are dosed per m² — incorrect area wastes money or causes patchy results. Topsoil and compost quantities are calculated per m² and depth. Aggregate and membrane quantities require accurate area to avoid under or over-ordering.

Rope Technique for Curves

For curved garden edges, lay a length of rope along the boundary, then straighten it out and measure. This gives the perimeter length accurately. For area, photograph the garden from above and divide into measurable shapes.
