Mulch reference
How much does a yard of mulch weigh?
Updated June 2026 10 min read
A cubic yard of dry wood mulch weighs about 600 pounds — roughly 400–800 lb depending on type, and 30–60% more after rain. Lightweight pine bark runs ~450 lb/yd³, shredded hardwood ~600 lb, and dense rubber mulch ~1,000 lb. A 2 cu ft bag weighs about 20 lb dry. The number that actually matters is whether the load clears your truck's payload — use the calculator below to check before you fill the bed.

Payload figures are conservative typicals — your real limit is on the door-jamb sticker. Need volume instead of weight? The mulch calculator turns bed size into cubic yards and bag count.
How big is a yard of mulch — and how heavy is that?
A "yard" of mulch is a cubic yard — a cube three feet on every side, which works out to 27 cubic feet or about 765 litres (0.765 cubic metres). Picture a pile roughly the size of a kitchen oven, or a heap covering a 9 ft × 12 ft bed three inches deep. That is the volume, and it never changes. What changes is the weight that volume carries: fill it with airy pine bark and it weighs ~450 lb; fill it with soggy compost and the identical space holds 1,400 lb. Volume tells you how far the mulch spreads; weight tells you whether your truck and your back can move it. People searching "how big is a yard of mulch" usually want both numbers, and they are two different questions.
Freshness matters too. Fresh-ground mulch weighs more than aged or composted mulch of the same wood, because the green fibre still holds sap and moisture. As a pile ages and dries over a season it loses weight and bulk — which is also why a yard scooped from the bottom of an old, compacted pile can weigh noticeably more than a fluffy scoop off the top.
Mulch weight by type: dry vs wet
Not all mulch weighs the same. Bark mulches are full of air and ride light; dense organic blends and rubber sit at the heavy end. The bars below show the dry weight (solid) and the wet weight (full bar) per cubic yard for the common mulches — the gap between them is the water a single rainstorm can add.
Solid bar = dry weight, faded extension = saturated weight, both per cubic yard. Planning figures; see our methodology for density ranges and sources. For mulch types and application depth, Penn State Extension is a solid reference.
Why moisture is the number nobody quotes you
Mulch is mostly air and wood fibre, and wood fibre is thirsty. A cubic yard of shredded hardwood that weighs ~600 lb fresh off a dry pile can absorb enough water in two days of rain to reach 900–1,000 lb — a 50–60% jump for the exact same volume. That water does nothing for your beds; it just rides in the truck and strains your back at the wheelbarrow. It also means a "weight" you read online is only half an answer unless it says dry or wet.
The practical upshot: order and plan against dry weight, then treat moisture as a safety margin, not a surprise. If a supplier weighs your bulk order on a scale after it has sat in the rain, you are paying for water — ask whether their pile is covered. And if you are hauling it yourself, assume the load could be 50% heavier than the dry chart says by the time you have it in the bed, because mulch yards are rarely under cover.
What a single weight figure leaves out
A number like "600 lb a yard" is a starting point, not the whole story. Several real-world factors shift the weight you actually lift or haul:
- Moisture state — dry, damp, or saturated swings the same yard by 30–60%.
- Fresh vs aged — green, fresh-ground mulch holds more sap and water than a seasoned pile.
- Compaction — a scoop off the bottom of an old pile is denser than a fluffy top scoop.
- Fines and soil content — double-shredded and compost blends carry fine particles that add weight without adding volume.
- Dye and additives — colorant adds little, but the recycled wood under dyed mulch is often denser scrap.
How much does a bag of mulch weigh?
Bagged mulch is processed and dried more than bulk, so it rides lighter than the bulk density suggests — until the bag tears and it soaks up rain on the pallet. Typical retail bag weights for wood mulch run:
| Bag size | Dry weight | Damp / wet weight | Bags per yard |
|---|---|---|---|
| 1.5 cu ft | ~15–25 lb | up to ~35 lb | 18 |
| 2 cu ft | ~20–30 lb | up to ~40 lb | 13.5 |
| 3 cu ft | ~30–40 lb | up to ~55 lb | 9 |
So a full yard of bagged mulch — 13.5 of those 2 cu ft bags — weighs roughly 270–400 lb dry, a bit less than the same volume in bulk because of the extra drying. The catch is price: bagged mulch usually costs two to three times more per yard than bulk. The crossover is covered in bulk vs bagged mulch.
Weight and handling, mulch by mulch
Seven mulches cover almost every bag and bulk pile you will meet. Each lists its dry weight per cubic yard, how much water it takes on, and the one handling quirk that matters.
Pine bark mulch
The lightest common mulch at ~300–500 lb/yd³ (use ~450). Chunky bark sheds water rather than soaking it, so it stays relatively light even wet. Gotcha: the same buoyancy means it floats and washes off slopes in heavy rain.
Cedar mulch
Light and aromatic, ~400–550 lb/yd³ dry. Its oils repel some insects and slow decay, so it holds weight and shape longer than hardwood. Gotcha: those oils can fade fast in sun, leaving a grey, lighter mat within a season.
Cypress mulch
Mid-weight at ~450–650 lb/yd³, it knits into a dense interlocking mat that resists washout. That mat also holds water, so wet cypress climbs toward 800 lb/yd³. Gotcha: it can shed water away from roots once it dries into a crust — rake it occasionally.
Shredded hardwood
The default bulk mulch, ~500–700 lb/yd³ dry (plan on 600). It mats well and stays put, but the fine shreds drink water — a wet yard can pass 950 lb. Gotcha: it ties up nitrogen as it breaks down; keep it off the stems of young plants.
Dyed double-shredded
Often recycled wood, double-ground and colored, ~700–900 lb/yd³ — heavier than it looks. The dye holds color a full season. Gotcha: cheap dyed mulch can be made from treated or painted scrap wood; buy from a yard that names its source.
Compost / leaf mulch
The heaviest organic option at ~800–1,000 lb/yd³ dry and up to 1,400 lb wet, because it is partly soil. Best for feeding beds, not topping paths. Gotcha: its weight means even one yard is a real load — and it compacts, so it needs a thinner layer.
Rubber mulch
Recycled tire crumb, ~800–1,200 lb/yd³ — nearly double dry wood. It barely absorbs water, so wet and dry weights are close. Gotcha: one cubic yard can max out a half-ton truck by itself, and it never feeds the soil.
Straw & pine needles
The featherweights — straw and pine straw run well under 150 lb/yd³ dry, so weight is never the limiter; volume is. Gotcha: they blow away easily and break down within a season, so they suit vegetable gardens more than permanent beds.
Will it fit in my truck? Payload, not volume
With light wood mulch, most pickups run out of bed space before they run out of payload — but with wet, compost, or rubber mulch the weight limit hits first, and that is the one that matters for safety and the law. Three rules keep a load legal and the suspension intact:
- 1. Find your real payload. It is on the yellow door-jamb sticker ("the combined weight of occupants and cargo should never exceed XXXX lb"), not the marketing "half-ton" name. Subtract passengers and gear first.
- 2. Match mulch weight to that number. A half-ton with ~1,700 lb of payload handles about 2.5 yards of dry hardwood (~1,500 lb) but only ~1.5 yards of compost or rubber. The calculator above does this for the type you pick.
- 3. Spread and tie down. Keep the load forward over the axle, not piled at the tailgate, and tarp it — both to stop blow-out on the highway and to keep rain from adding hundreds of pounds on the way home.
Worked example — a half-ton run. Say you have an F-150 with 1,700 lb of payload and you and a passenger (~350 lb of people and tools) are aboard, leaving ~1,350 lb for mulch. Dry shredded hardwood at 600 lb/yd³ means you can safely take about 2 cubic yards (1,200 lb) — comfortably under the limit and about as much as a short bed holds anyway. But if the yard's pile is rain-soaked at ~950 lb/yd³, that same 2 yards is 1,900 lb and you are 550 lb over. The fix is one of three: take 1.5 yards now and come back, wait for a dry day, or switch to a yard of light pine bark. The calculator above flags exactly this before you load.
Five mulch-weight mistakes that cause problems
1. Using a dry weight for a wet load
Planning a truckload off the 600 lb dry figure when the yard's pile is soaked can put you 300–400 lb over what you expected — and possibly over payload.
2. Treating rubber like wood mulch
Rubber mulch weighs nearly double. People order "a couple of yards" the way they would wood mulch and overload a half-ton truck with the first yard and a half.
3. Trusting the "half-ton" name
A modern half-ton's real payload ranges from ~1,300 to over 2,000 lb depending on trim and options. Read the door sticker — the name is not the limit.
4. Ignoring the trailer's own weight rating
A small utility trailer has a GVWR too. Two yards of wet hardwood (~1,900 lb) plus the trailer can exceed both the trailer's rating and your hitch's tongue-weight limit.
5. Confusing weight with coverage
Heavier mulch does not cover more ground — coverage is about volume and depth. For how far a yard spreads, use the how much mulch guide, not the weight.
When mulch weight actually changes your plan
- Rooftop & balcony beds: structural load limits matter — use light pine bark, never compost or rubber.
- Raised beds on decks: the same concern; a yard of wet compost is ~1,400 lb concentrated on a small footprint.
- Slopes: heavier, interlocking cypress or shredded hardwood stays put; light pine bark floats off.
- Long wheelbarrow runs: dry pine bark or cedar saves your back over a hundred trips; weight adds up fast.
- DIY pickup hauling: match yards to your door-sticker payload, and assume wet if the forecast is bad.
- Bagged for apartments: a 2 cu ft bag at ~20–40 lb is the realistic limit for carrying up stairs.
What the delivery crews actually do
Landscape yards plan their trucks by weight, not by how full the bed looks. A dump truck rated for, say, 10 tons will happily take 12–14 cubic yards of dry wood mulch because it is so light — but the same truck is capped at a few yards of wet topsoil or stone. They also load mulch in the morning before the day's rain and tarp every load, because they know a covered pile and a dry haul is the difference between a legal axle weight and a ticket. For a DIY load, copy the habit: haul dry, tarp it, and weigh your plan against the sticker.
Mulch weight: common questions
How much does a yard of mulch weigh?
A cubic yard of dry wood mulch weighs about 400–800 lb, with shredded hardwood averaging ~600 lb. Soaked by rain, the same yard can hit 800–1,000+ lb — moisture is the biggest variable.
How much does a 2 cu ft bag of mulch weigh?
A 2 cu ft bag of bagged hardwood mulch weighs about 20 lb when kiln-dried and up to 40 lb if it has absorbed moisture. A 1.5 cu ft bag runs roughly 15–30 lb, and a 3 cu ft bag about 30–40 lb.
How heavy is a yard of mulch when wet?
Wet mulch weighs 30–60% more than dry. A 600 lb dry yard of hardwood can reach 900–1,000 lb after two days of rain, because water fills the air gaps between the shreds.
How many yards of mulch can a pickup truck hold?
A half-ton pickup (F-150, Silverado 1500) holds about 2–2.5 cubic yards of dry wood mulch by weight; a compact pickup tops out near 1.5 yards. Volume usually runs out before payload does with light wood mulch.
How many pounds is a yard of mulch?
Between roughly 400 and 1,000 pounds depending on type and moisture. Use ~600 lb for dry shredded hardwood, ~450 lb for pine bark, and ~1,000 lb for rubber mulch as planning numbers.
How many litres are in a cubic yard of mulch?
One cubic yard equals about 765 litres (0.765 cubic metres). That is the volume; the weight still depends on the mulch type and how wet it is.
Does rubber mulch weigh more than wood mulch?
Yes — rubber mulch weighs roughly 800–1,200 lb per cubic yard, nearly double dry wood mulch. It barely absorbs water, so its wet and dry weights are close, but one yard can max out a half-ton truck on its own.
Why does mulch weight matter for delivery?
Because trucks are limited by payload, not just bed volume. Exceeding your truck or trailer rating is unsafe and illegal, and a "light" load of wet or rubber mulch can quietly cross that line.
