How the garden area calculator works

Rectangle / square garden:
The calculator multiplies length by width, then multiplies by the number of beds or areas.

Circle garden:
Enter the garden diameter and the calculator uses radius to estimate the round garden area.

Triangle garden:
Enter triangle base and height to estimate triangular garden area.

Multiple beds:
Enter bed size and bed count to calculate total area, usable planting area, paths, material volume, and estimated cost.

Why use a garden area calculator?

A garden area calculator helps estimate garden size before buying soil, mulch, compost, seed, plants, edging, or landscape materials.

It can be useful for raised beds, vegetable gardens, flower beds, lawns, landscaping projects, native plantings, garden layouts, and square foot garden planning.

What your result means

Your result shows total garden area, usable planting area, path or non-planting area, square feet, square yards, acres, square meters, hectares, estimated plants, soil or mulch volume, cubic yards with extra allowance, and estimated material cost.

For a rectangle or square garden, multiply length by width. For a circle, use π times radius squared. For a triangle, multiply base by height and divide by 2.

How many square feet is my garden?

Enter the garden shape and dimensions into the calculator. The result will show total square feet, square yards, acres, square meters, and hectares.

What is usable planting area?

Usable planting area is the part of the garden used for plants after subtracting paths, borders, access lanes, or other non-planting areas.

Can this estimate soil and mulch too?
