FREE DIY ESTIMATOR
Mulch Calculator
Estimate how much mulch you need by cubic yards or bags based on bed size and depth.
How to estimate mulch
Measure the bed length and width in feet, choose the depth in inches, and the calculator converts that volume into cubic yards and bag counts.
Measuring tips
- Break irregular beds into simple rectangles.
- Use a consistent target depth across the area.
- Check the cubic-foot volume printed on each bag.
- Add a small allowance for uneven ground and settling.
Before you buy
Keep mulch away from trunks and plant crowns, and verify whether your landscape needs fresh mulch or only a top-up layer.
