A cubic yard of wood mulch weighs about 450 to 800 pounds as it is usually delivered — slightly damp, straight off the supplier’s pile. Bone-dry, the same yard is 300–500 lb; after a soaking rain it can pass 1,000 lb. A standard 2 cu ft bag weighs 22–37 lb dry and closer to 40–50 lb if it has been sitting outside on a pallet.
Why every source gives a different number
Search for mulch weight and you will find answers from 400 to 1,500 lb per yard, sometimes on the same page. They are not all wrong — they are measuring different states of the same material. Wood holds water like a sponge, so moisture changes the weight of a yard by two to three times, while the volume barely moves. Bagged mulch is usually the driest; bulk mulch from an outdoor pile is damp; mulch after a week of rain is wet. The second variable is the cut: finely shredded hardwood packs tight and runs heavy, while airy pine bark nuggets leave more air between pieces.
One quick check catches most bad figures: a cubic yard is 27 cubic feet, or 13.5 bags of 2 cu ft. If a source says a yard weighs 700 lb dry but a 2 cu ft bag weighs 25 lb dry, those two numbers cannot both be true — 13.5 × 25 lb is only 340 lb.
How much does a yard of mulch weigh by type?
| Mulch | Dry (bagged) | Damp (typical bulk) | After heavy rain |
|---|---|---|---|
| Double-shredded hardwood | 400–500 lb | 600–800 lb | 900–1,200 lb |
| Dyed wood mulch | 350–450 lb | 500–700 lb | 800–1,000 lb |
| Pine bark nuggets | 300–400 lb | 450–600 lb | 700–900 lb |
| Cedar or cypress | 300–400 lb | 450–650 lb | 700–950 lb |
| Rubber mulch | 600–800 lb in any weather — rubber does not absorb water | ||
| Compost, for comparison | 1,000–1,600 lb | ||
| Topsoil, for comparison | 2,000–2,200 lb dry | ||
Rubber mulch is the odd one out: about twice as heavy as dry wood mulch, but it weighs the same wet or dry, so its number is the most predictable. Pine straw is not sold by the yard at all — it comes in bales, which is a different calculation.
How much does a bag of mulch weigh?
A 2 cu ft bag of wood mulch weighs 22–37 lb dry. Bag weight scales directly with the cubic feet printed on the label, so the same density gives you every size:
| Bag size | Dry | Damp (pallet left outside) | Bags per cubic yard |
|---|---|---|---|
| 1.5 cu ft | 17–28 lb | 28–44 lb | 18 |
| 2 cu ft (standard) | 22–37 lb | 37–59 lb | 13.5 |
| 3 cu ft | 33–56 lb | 56–89 lb | 9 |
| 0.8 cu ft rubber mulch | 18–24 lb | 34 | |
Those bag counts are why the bag and yard figures should agree: 13.5 bags at 22–37 lb is 300–500 lb, the same as a dry yard. For the full breakdown by bag size, see how many bags is a yard of mulch.
How much mulch can a pickup carry?
With mulch, a half-ton pickup usually runs out of bed space before it runs out of payload — the opposite of soil and stone. A typical half-ton truck (F-150, Silverado 1500, RAM 1500) is rated for roughly 1,500–2,000 lb; check the sticker on the driver’s door jamb for yours. Using a conservative 1,500 lb:
| Bed (level-full) | Dry | Damp | Soaked |
|---|---|---|---|
| 5.5 ft short · ~1.7 yd³ | 1.7 yd³ | 1.7 yd³ | 1.4 yd³ ⚠ |
| 6.5 ft standard · ~2.0 yd³ | 2.0 yd³ | 1.9 yd³ | 1.4 yd³ ⚠ |
| 8 ft long · ~2.2 yd³ | 2.2 yd³ | 1.9 yd³ ⚠ | 1.4 yd³ ⚠ |
⚠ marks loads where weight, not space, is the limit. If the supplier loads soaked mulch to the top of an 8 ft bed, that is roughly 2,400 lb — well over a half-ton truck’s rating. Ask how wet the pile is before they load, and stop at about 1.4 yards when it has been raining.
Compare that with soil: a yard of topsoil weighs over a ton, so the same truck only carries about half a yard of it. See how much a yard of topsoil weighs if you are hauling both.
How much do you need to buy?
You buy mulch by volume, not weight — weight only matters for hauling. Use the mulch calculator to turn your bed sizes into cubic yards and bag counts; it also estimates the weight of your order by mulch type so you know whether one truck trip will do.
