SITE MEASUREMENT

Measuring an Irregular Landscape Area

Irregular beds and lawns are easier to estimate when divided into rectangles, triangles, and circles that can be measured separately.

SHORT ANSWER

Start with the inputs you can verify

Irregular beds and lawns are easier to estimate when divided into rectangles, triangles, and circles that can be measured separately.

What the estimate means

Sketch the site and mark every dimension before doing arithmetic.

Avoid counting overlapping shapes twice, and subtract patios, buildings, or other excluded areas.

Where estimates go wrong

Use the same unit for every shape and keep a record of assumptions for ordering.

Keep the source measurements and assumptions with the result so another person can review or update the estimate later.

A practical workflow

  1. Draw a plan and divide the area into simple shapes.
  2. Measure each shape and calculate its area.
  3. Add included areas, subtract exclusions, and spot-check the result against the site.
