How to use it
- Enter the desired mulch depth in inches.
- Click the Calculate button.
- Read the coverage area in square feet.
This tool converts the volume of one cubic yard (27 ft³) into the square‑foot area you can spread at any depth you enter. Knowing the exact coverage helps you buy the right amount of mulch, avoid over‑ordering, and keep your landscaping budget on track. Simply type the depth in inches, the calculator changes it to feet, divides the 27 ft³ by that depth, and shows the resulting square footage. The number you see is the maximum area you can cover evenly; if you plan for a slightly deeper layer, the area will shrink accordingly. You can also adjust the depth to see how a shallower spread increases the coverage, which is useful for large lawns or when you have a limited budget. The calculator works instantly in your browser, so no data is saved or shared.
Pro tips
- Add 5‑10% extra mulch for settling and wind‑drift.
- Round the result up to the nearest whole 10 sq ft for easier ordering.
- Buy mulch in bulk if the coverage exceeds a single bag’s capacity.
- Double‑check the depth conversion; 12 in = 1 ft.
Real-life examples

Case study
Jenna wanted to mulch her 200‑sq‑ft patio at 2 in depth. Using the calculator she saw she needed only 162 sq ft, so she ordered a single cubic yard, saved $40, and avoided excess material.
