About 0.4 short tons per cubic yard for typical wood mulch; density varies widely with material and moisture.

Approximate volume

25 yd³

High confidence

About 0.4 short tons per cubic yard for typical wood mulch; density varies widely with material and moisture. The inverse of the volume-to-weight figure. Compare the resulting volume against your compacted or settled requirement, not the loose figure.

What this calculation does not cover

  • Dividing this volume by the bed area gives an even depth that no bed actually receives. Freshly dug ground and beds full of established planting take the first of the load into hollows and gaps without building depth anywhere, so the layer over the open ground ends up shallower than the arithmetic promises.
  • The volume here is what is being added, not what will be lying on the bed. Where the last mulching is still in place the two stack up, and a mat well past the intended depth sheds rain rather than letting it through.
  • The volume tipped is not the volume that reaches the bed. The bottom of the heap comes up with grit from whatever it was tipped on and gets left or binned rather than spread, and fine dry grades blow off an open barrow and past the bed edge.

Converting a mulch tonnage into cubic yards is mainly a haulage and handling question, since coverage is almost always specified by volume and depth. The number to watch is not the weight but the settlement: mulch compresses and decomposes, losing depth over a season, which is why beds mulched to the correct depth in spring look thin by the following year. Spreading slightly deeper than the target accounts for that, though piling mulch against stems and trunks causes rot regardless of how the quantity was calculated.

Frequently asked questions

Will a tonne of mulch fit in my trailer?
By weight, almost certainly. By volume, quite possibly not — mulch is bulky and light, so a trailer runs out of space long before it runs out of payload. Convert and check the volume against the trailer's capacity.
How much does mulch settle?
Enough over a season, through compression and decomposition, that beds mulched to the target depth look thin within a year. Spreading slightly proud is usual practice for that reason.
Is bagged or bulk mulch better value?
Bulk is almost always cheaper per cubic yard, but bags are easier to handle and store. The crossover depends on how much you need and whether you can take a bulk delivery.
Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.
