Landscape Area Calculator

Calculate landscaping square footage for beds, borders, yards, islands, and outdoor areas. Estimate mulch, rock, soil, edging, plant count, irrigation water, waste, and project cost.

Calculate Landscape Area

Landscape Area = Length × Width. Material Volume = Area × Depth.

How the landscape area calculator works

Rectangular mode:
The calculator multiplies landscape length by width to estimate square footage, perimeter, material volumes, and cost.

Multiple areas mode:
The calculator multiplies one landscape area by the number of same-size landscape sections.

Known area mode:
The calculator starts from a known landscape square footage and estimates mulch, rock, soil, plants, edging, water, and cost.

Circular mode:
The calculator uses diameter to estimate circular landscape area and border length.

Why use a landscape area calculator?

A landscape area calculator helps estimate square footage and materials for landscape beds, mulch beds, rock beds, shrub beds, flower beds, borders, islands, and yard projects.

It can help calculate landscape area, area with waste, mulch volume, rock volume, soil volume, edging length, plant count, irrigation water, and estimated project cost.

What your result means

Your result shows gross landscape area, excluded area, net landscape area, area with waste, mulch area, rock area, planting area, material volumes, plant count, edging length, water needed, and estimated cost.

Frequently asked questions

How do I calculate landscape area?

For a rectangular landscape bed, multiply length by width. For example, a 30 foot by 12 foot bed has 360 square feet.

How much mulch do I need for landscaping?

Multiply the mulch area by mulch depth, then divide cubic feet by 27 to convert to cubic yards.

How much landscape rock do I need?

Multiply the rock area by rock depth. The calculator converts the result into cubic feet and cubic yards.

How do I estimate plants for a landscape bed?

Divide planting area by the square footage used by one plant based on your selected plant spacing.

Is this landscape calculator exact?

No. It is an estimate. Actual material needs vary by bed shape, curves, slopes, depth, compaction, edging, plant spacing, waste, and installation method.
