About the Garden Area Calculator
Landscaping materials like decorative river rock, decomposed granite, and organic bark mulch are delivered by bulk cubic yard or bulk bag, not small retail sacks.
A typical 3-inch depth provides adequate weed suppression and moisture retention without choking plant crowns. Accurately sizing garden plots prevents unsightly shallow patches and surplus gravel piles on your driveway.
Underlying Formula
Ground Area × Material Depth ÷ 27 = Cubic Yards
Area = L × W | Volume (cu yd) = (Area × Depth in ft) ÷ 27

How to Use This Tool
Follow these four essential steps to take accurate architectural measurements and prepare your project quantities.
Step 1
Measure length and width of the outdoor zone (beds, terrace, or lawn).
Step 2
Select the application depth (2" for refresh, 3" for new mulch, 4" for gravel paths).
Step 3
Review both surface area (for sod/seed) and cubic volume (for bulk delivery).
Step 4
Add 10% for compaction and subgrade settling.

Frequently Asked Questions
Common queries answered by our architectural editors and renovation consultants.
How deep should mulch and gravel beds be?
Bark mulch performs best at 2 to 3 inches. Pea gravel or decorative stone pathways should be 3 to 4 inches deep over a permeable weed membrane.
How much area does 1 cubic yard of mulch cover?
One cubic yard covers approximately 108 square feet at a 3-inch depth, or 162 square feet at a 2-inch depth.
How do I measure an organic curved garden bed?
Use a garden hose to trace the perimeter curve, measure the longest axis and average width, or divide the kidney shape into two overlapping ovals.
