How to use it
- Enter length in feet
- Enter width in feet
- Set coverage per unit (default 50 sq ft)
- Read units needed and area output
Enter the length and width of the area you plan to mulch, then set the coverage per unit (default 50 sq ft). The calculator multiplies length by width to give total square footage, then divides by the coverage to show how many units you must purchase. The result appears as Units needed (rounded up) and Area in square feet. Knowing the exact unit count prevents over‑buying and saves money, while ensuring you don’t run out mid‑project. Use the editable coverage field if your mulch bag differs from the default. The instant output lets you compare prices, plan delivery, and schedule work without guesswork. You can also copy the result to your clipboard, add a 10% waste factor, and instantly see the adjusted total before placing an order. This quick check works on desktop, tablet, or phone, so you stay on track wherever you measure.
Pro tips
- Add 10% extra for wind or settling
- Round up to the next whole unit to avoid shortfalls
- Order a little more than calculated to cover future touch‑ups
- Double‑check bag coverage if it differs from the default 50 sq ft

Case study
Sarah measured a 12 ft × 15 ft garden, entered the numbers, and the calculator showed 4 units needed (total 180 sq ft). She ordered four bags, avoided a costly extra trip, and completed the project on schedule.
