Calculate garden bed area for raised beds, in-ground beds, flower beds, herb beds, vegetable beds, row beds, and multiple garden beds. Estimate square feet, square yards, perimeter, usable planting area, soil coverage, mulch coverage, compost coverage, and material cost.
Rectangle mode:
The calculator multiplies bed length by bed width to estimate square feet and perimeter.
Multiple beds mode:
The calculator multiplies one bed’s area by the number of matching beds.
Circle and triangle modes:
The calculator uses basic area formulas for rounded or triangular planting beds.
Row bed mode:
The calculator estimates planted row area and full layout area including row spacing or aisles.
A garden bed area calculator helps estimate the actual square footage of planting beds before buying soil, compost, mulch, fertilizer, seed, edging, or irrigation supplies.
It can help compare bed layouts, plan raised bed spacing, estimate material coverage, calculate perimeter, and avoid underbuying or overbuying garden materials.
Your result shows total garden bed square footage, square yards, acres, perimeter, usable planting area, material volume, material units needed, and estimated material cost based on the selected bed shape.
For a rectangular garden bed, multiply length by width. For multiple matching beds, multiply the result by the number of beds.
Use inside dimensions for planting area, soil volume, compost, and mulch. Use outside dimensions for frames, edging, paths, and border layout.
A 4 × 8 garden bed is 32 square feet.
Multiply bed area by material depth in inches, then divide by 12 to convert the depth to feet. The result is cubic feet.
No. This is an estimate. Actual bed area can vary if beds are curved, sloped, irregular, uneven, or measured from different edges.
