Approximate weight

3.5 short tons

High confidence

About 0.35 short tons per cubic yard for bark mulch; heavier than fresh chip, lighter than compost. A planning figure, not a specification. Confirm the figure with your supplier or waste contractor before relying on it.

Conversion factor applied
0.35 short tons per cu yd

Bark is bought by volume for beds and borders, and its weight matters mainly for transport. It sits between wood chip and compost in density — coarser and more durable than chip, lighter than composted material. Its advantage over chip is longevity: bark breaks down more slowly, so a bed mulched with bark holds its depth through more than one season, which usually justifies the higher price per cubic yard over repeated topping up.

Add the equipment this sizes

This result is a specification — 3.5 short tons — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

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.

Frequently asked questions

Bark or wood chip?
Bark lasts longer and looks more uniform; chip is cheaper and breaks down faster. For beds that will not be disturbed, bark's longevity usually repays the extra cost through fewer top-ups.
How deep should bark be?
Deep enough to suppress weeds without smothering roots, and always kept clear of stems and trunks. Piling mulch against woody plants traps moisture against the bark and causes rot.
Does bark acidify soil?
The effect is modest and largely confined to the surface layer where it decomposes. It is rarely a practical concern for ordinary planting, though acid-sensitive plants are worth considering separately.
