How to use it

- Read the units needed and total area
What it does The Mulch Calculator takes the length and width of your planting area, multiplies them to give total square footage, then divides by the coverage per unit (default 50 sq ft) to tell you exactly how many bags or rolls you need.
Why it matters Buying too little leaves gaps; buying too much wastes money and space. Knowing the precise number helps you budget, plan delivery, and keep your garden looking even.
How to read the results
- Units needed – round up to the nearest whole unit; you can’t purchase a fraction.
- Area – shows the total square footage you entered, confirming the calculation.
Pro tips
- Add 5‑10% extra for settling or compaction
- Always round up to the next whole unit
- Measure twice, especially for irregular shapes
- Check bag dimensions and weight before ordering
