If you want the shortest accurate answer to how much does a yard of mulch weigh, here it is: most wood mulch weighs about 400 to 800 pounds per cubic yard when dry, and often 800 to 1,000+ pounds when wet. Rubber mulch is usually heavier to begin with, often around 800 to 1,200 pounds per cubic yard, but it changes much less with moisture than wood-based products do, according to Friendly Tree Service, Pro Mulch Calculator, and Best Bark Mulch.

That wide spread surprises people because a yard is a measure of volume, not weight. One cubic yard of dry pine bark, one cubic yard of damp shredded hardwood, and one cubic yard of rubber mulch all occupy the same space, but they can differ by hundreds of pounds.

That matters any time you are deciding between bulk and bags, estimating how many trips a pickup can handle, or planning cleanup after tree work. If this project is part of a larger yard-restoration job, you may also want to compare it with the other common post-removal expense in our guide to stump grinding costs.

For quick planning, this is the most useful way to think about it:

Mulch type	Dry weight per cubic yard	Wet weight per cubic yard	Practical takeaway
Wood mulch, general	400–800 lb	800–1,000+ lb	Fine for rough estimating, but moisture changes everything
Shredded hardwood	500–700 lb	800–1,000+ lb	Good benchmark for common bulk mulch
Cedar mulch	400–600 lb in some guides; about 700 lb in others	700–900 lb	Usually lighter to midweight, but not always the lightest
Pine bark nuggets	350–500 lb	600–800 lb	One of the lighter organic options
Rubber mulch	800–1,200 lb	800–1,200 lb	Heavier, but more predictable
Straw mulch	350–500 lb	900–1,400+ lb	Biggest moisture swing
Compost / leaf mulch	600–1,000 lb	1,000–1,400+ lb	Can get heavy fast; ask what the mix actually is

These are planning ranges, not certified densities, and they vary by product, particle size, and moisture level.

What Is a Cubic Yard of Mulch?

A cubic yard is a unit of volume equal to 27 cubic feet, or a space measuring 3 feet by 3 feet by 3 feet. That is the standard bulk measure suppliers use for mulch, compost, soil, and similar landscape materials, according to Friendly Tree Service, Sod Depot, and Mulch Barn Supply.

For homeowners, the easiest way to understand a yard is by converting it into bags and coverage:

1 cubic yard = 27 cubic feet
1 cubic yard = about 13.5 bags of 2-cubic-foot mulch, usually rounded to 13 or 14 bags
1 cubic yard = 9 bags of 3-cubic-foot mulch

Coverage depends on how deep you spread it. The standard math works out to:

About 162 square feet at 2 inches deep
About 108 square feet at 3 inches deep per Sod Depot and Friendly Tree Service.

You will also see some supplier pages round the 3-inch figure to about 100 square feet. That is not wildly wrong for quick shopping math, but the more exact formula-based figure is 108 square feet for a true cubic yard, as shown by Sod Depot and contrasted with the rougher rule on Mulch Barn Supply.

This is why the weight question often comes bundled with two other questions:

How much space is a yard?
How much area will it cover?
How much will it weigh in my truck?

The first two answers are fixed. The third is not. A yard is always 27 cubic feet, but it does not always weigh the same.

Typical Weight Ranges for Wood Mulch: Dry vs Wet

For ordinary wood-based mulch, the most defensible overall range in the evidence is about 400 to 800 pounds per cubic yard when dry. That range appears across independent supplier FAQs, weight guides, and calculators including Friendly Tree Service, Chippy Tools, Caesar Cipher, and Pro Mulch Calculator.

Once the same material gets wet, the number rises quickly. Multiple guides put wet wood mulch in the 800 to 1,000+ pound range, with some noting that soaked loads can push higher than that after rain or when the mulch is freshly processed and moisture-heavy, according to Pro Mulch Calculator, Best Bark Mulch, and Mulch Smart KC.

For the most common homeowner benchmark—shredded hardwood—the numbers are a little tighter:

Dry shredded hardwood: roughly 500 to 700 pounds per cubic yard
Wet shredded hardwood: roughly 800 to 1,000+ pounds per cubic yard per Best Bark Mulch and Best Bark Mulch’s weight guide.

Pro Mulch Calculator lands in almost the same place, using about 600 pounds dry and 900 to 1,100 pounds wet for shredded hardwood. That makes around 600 pounds per cubic yard a fair working estimate for common hardwood mulch in ordinary conditions, but it should be treated as a midpoint, not a universal truth.

For example, Caesar Cipher uses 800 pounds per cubic yard as a general calculator assumption, while other sources use lower midpoints for dry hardwood.

A practical way to use the evidence is this:

Dry to moderately dry common wood mulch: expect roughly 600 to 800 pounds per yard
Fresh, rain-soaked, or very finely shredded mulch: assume roughly 900 to 1,000+ pounds per yard This framing fits the combined direction of Sod Depot, Caesar Cipher, Pro Mulch Calculator, and Best Bark Mulch.

That is more useful than chasing one exact number, because the evidence does not support a single fixed weight for all wood mulch.

Weights by Mulch Type: Hardwood, Cedar, Pine, Rubber, and More

“Mulch” is not one material. It is a category, and the weight of one cubic yard changes a lot depending on what is actually in the pile.

Shredded hardwood

This is the best general benchmark for most bulk mulch purchases. The most repeated figures place shredded hardwood at 500 to 700 pounds dry and 800 to 1,000+ pounds wet per cubic yard, according to Best Bark Mulch and Best Bark Mulch’s guide. Pro Mulch Calculator uses about 600 pounds dry and 900 to 1,100 pounds wet, which is effectively the same planning zone.

Cedar mulch

Cedar is more variable in the published figures. Some supplier-style guides list it around 400 to 600 pounds dry and 700 to 900 pounds wet per cubic yard, per Best Bark Mulch. But Pro Mulch Calculator gives cedar a higher single estimate of about 700 pounds per yard.

Pine bark nuggets

Pine bark nuggets are usually lighter than shredded hardwood. Best Bark Mulch lists 350 to 500 pounds dry and 600 to 800 pounds wet, while Pro Mulch Calculator puts pine bark around 450 pounds dry and 600 to 750 pounds wet. If hauling weight is your main concern, pine bark is one of the better organic choices.

Rubber mulch

Rubber mulch is the major outlier. Multiple sources place it around 800 to 1,200 pounds per cubic yard, and they also agree that its weight is largely unchanged by rain because rubber does not absorb water the way organic mulch does, according to Pro Mulch Calculator and Best Bark Mulch. One calculator centers that estimate even more narrowly at about 1,150 pounds per yard.

Straw mulch

Straw is one of the lightest dry materials and one of the least predictable wet ones. Supplier tables from Best Bark Mulch and Mulch Smart KC list straw around 350 to 500 pounds dry, but 900 to 1,400+ pounds wet. Pro Mulch Calculator gives a lower wet estimate of about 800 pounds, but the direction is the same: straw can swing dramatically with moisture.

Compost or leaf mulch

This category is the messiest because suppliers use the label differently. Mulch-focused tables commonly put compost or leaf mulch around 600 to 1,000 pounds dry and 1,000 to 1,400+ pounds wet, according to Best Bark Mulch and Mulch Smart KC. But broader compost listings can run heavier: Friendly Tree Service gives 1,000 to 1,600 pounds per cubic yard for compost, while Mulch Barn Supply lists its garden compost at 800 pounds per yard. So if a supplier says “compost mulch,” it is worth asking whether they mean a loose leaf-heavy product, a denser compost, or a blended material.

If you want a simple dry-weight ranking from lighter to heavier, it usually looks something like this:

That ranking is supported broadly by Best Bark Mulch and Pro Mulch Calculator, though wet conditions can rearrange it fast because organic products absorb water and rubber mostly does not.

Why Moisture Content Changes Mulch Weight So Much

Moisture is the biggest reason mulch weights vary so widely. Across the evidence, a good rule of thumb is that water often adds 30% to 50% or more to the weight of organic mulch, according to Mulch Smart KC, Best Bark Mulch, and Pro Mulch Calculator.

Some sources suggest the jump can be even larger. Pro Mulch Calculator says wood mulch can be 50% to 80% heavier when wet, and Best Bark Mulch gives a hardwood example moving from about 550 pounds dry to 900 pounds wet, which is roughly a 60% to 70% increase.

The reason is straightforward. Organic mulch is made of fibrous, porous material with lots of surface area and air spaces. Shredded wood, bark, leaves, and straw all hold water within the fibers and between the pieces. That is also why finer particle size tends to hold more water than chunkier mulch, a point specifically noted by Mulch Smart KC.

A coarse bark nugget and a fine, double-ground wood mulch may both be sold as mulch, but they will not react the same way to rain. The finer material exposes more surface area and usually traps more moisture.

The most dramatic examples are straw and compost-like mulch. In the supplier ranges, straw can rise from roughly 350 to 500 pounds dry to 900 to 1,400+ pounds wet, and compost/leaf mulch can climb from 600 to 1,000 pounds dry to 1,000 to 1,400+ pounds wet, according to Best Bark Mulch and Mulch Smart KC. Those are not minor swings. They are the difference between an easy load and a load that changes your hauling plan.

Rubber mulch is the exception. Multiple guides say its weight stays essentially the same in wet or dry weather because it does not absorb water the way organic materials do, according to Pro Mulch Calculator and Best Bark Mulch.

For real-world planning, this leads to the safest rule in the whole article:

If you do not know how dry the mulch is, estimate from the wet side.

If it rained recently, if the pile was stored outdoors, if the loader is scooping from the bottom of a stockpile, or if the mulch is finely shredded, the wet range is the better assumption.

Pickup Truck Capacities: How Many Yards Can You Haul?

This is where people get in trouble, because bed volume and payload are not the same thing.

A truck bed may have enough physical space for a certain number of cubic yards, but the truck may not have the payload capacity to carry that weight. Friendly Tree Service makes this point directly, and Mulch Barn Supply gives bed-size estimates that are useful for space planning, not universal approval to load every truck that full.

For bed volume, one supplier guide says:

Standard 6-foot bed pickup = about 2 yards of mulch
Standard 8-foot bed pickup = about 3 yards of mulch per Mulch Barn Supply.

Friendly Tree Service gives a similar big-picture estimate, saying full-size 3/4-ton or 1-ton pickups can hold 2 to 3 cubic yards of mulch, while warning that weight must be considered and vehicle specs should not be exceeded.

For payload, the published planning figures in the evidence vary because trucks vary. Mulch Smart KC cites a common general pickup payload figure of about 1,000 to 1,500 pounds, while Best Bark Mulch says many half-ton trucks fall somewhere in the broader 1,000 to 2,000 pound payload range. Those are rough examples, not universal limits.

That means a yard of mulch can be easy or risky depending on what kind of mulch it is and how wet it is:

1 dry yard of common wood mulch often lands in the 400 to 800 pound range
1 wet yard of wood mulch can be 800 to 1,000+ pounds
1 yard of rubber mulch can already be 800 to 1,200 pounds
2 wet yards of wood mulch can easily push 1,600 to 2,000+ pounds based on the per-yard ranges reported by Friendly Tree Service, Pro Mulch Calculator, and Best Bark Mulch.

That is why apparently conflicting truck advice can all be true at once. Caesar Cipher says a standard pickup can safely carry about 1 cubic yard as a cautious default. Supplier pages discussing 2 or 3 yards are usually talking about what may fit by volume in larger beds or heavier-duty trucks, not what every pickup should haul without checking the payload sticker.

For homeowners, the most defensible way to use the evidence is:

For a half-ton pickup, 1 yard of wood mulch is the safest rough planning assumption, especially if the material may be damp.
2 yards may fit in some beds, but whether that is reasonable depends on the truck’s actual payload, the number of passengers, and whether the mulch is dry, wet, rubber, or compost-heavy.
For 3/4-ton and 1-ton trucks, 2 to 3 yards of mulch may be realistic, especially with dry wood mulch, but that still depends on the actual vehicle and load. This is the common theme across Friendly Tree Service, Mulch Barn Supply, and Best Bark Mulch.

The final check is not a website average. It is your door-jamb payload label and your vehicle’s own specifications. The evidence repeatedly supports using published mulch weights as rough planning numbers and then verifying against the truck’s actual rating rather than the truck class name alone, especially in Friendly Tree Service and Best Bark Mulch.

Bagged Mulch vs Bulk: Equivalents and Weight Differences

By volume, bagged and bulk mulch are easy to compare.

1 cubic yard = about 13.5 bags of 2-cubic-foot mulch
1 cubic yard = 9 bags of 3-cubic-foot mulch according to Sod Depot, Friendly Tree Service, and Caesar Cipher.

By weight, the comparison gets fuzzier.

Pro Mulch Calculator says a 2-cubic-foot hardwood bag often weighs about 20 to 30 pounds dry and 30 to 45 pounds wet. That is useful for lifting and trip planning, but it does not mean a yard of bagged mulch will always weigh exactly the same as a yard of loose bulk mulch.

There are three main reasons:

1. Moisture can differ

Bagged mulch at a store may be relatively dry, but it can also pick up moisture depending on storage. Bulk mulch stored outdoors is even more exposed to rain and irrigation. The same material can land in very different weight ranges depending on conditions, as shown by Best Bark Mulch and Mulch Smart KC.

2. Compaction can differ

Bags are filled, stacked, and compressed. Bulk mulch is loose. That does not change the labeled volume, but it can change how the material settles, handles, and feels when you compare a stack of bags with a scooped yard from a loader bucket.

3. The material itself can differ

A retail bag labeled “mulch” may be dyed hardwood fines, bark, cedar blend, or some other processed wood product. A bulk yard might be arborist chips, bark nuggets, shredded hardwood, or compost-blended mulch. Those products do not have the same density even before weather enters the picture, according to Pro Mulch Calculator and Best Bark Mulch.

For homeowners, the practical difference is simple:

Bagged mulch is easier to count, carry, and split across multiple trips.
Bulk mulch is usually more efficient for large projects, but its real hauling weight is less predictable because it is loose and often stored outdoors.

If you are anywhere near your truck’s payload limit, bulk mulch deserves the more cautious estimate.

Comparisons: Mulch vs Compost, Soil, Gravel Weights

One of the best ways to understand mulch weight is to compare it with the other materials people commonly haul in the same truck.

For wood mulch, the broad dry range is still about 400 to 800 pounds per cubic yard, according to Friendly Tree Service, Chippy Tools, and Pro Mulch Calculator.

For compost, the spread is wider because suppliers define the product differently. A practical planning range is about 600 to 1,600 pounds per cubic yard when you combine mulch-style compost or leaf-mulch figures with broader compost listings from Mulch Smart KC, Best Bark Mulch, and Friendly Tree Service. Mulch Barn Supply also lists its own garden compost at 800 pounds per yard, which shows how much compost weights can overlap with wet mulch on the lighter end.

For topsoil, Chippy Tools gives 1,400 to 2,000 pounds per cubic yard, while Mulch Barn Supply lists 1 yard of topsoil = 2,000 pounds.

For soil blends, Friendly Tree Service goes higher still, listing 2,200 to 2,700 pounds per cubic yard.

For gravel or rock, Pro Mulch Calculator gives 2,600 to 3,000 pounds per cubic yard, with pea gravel specifically around 2,700 pounds per yard.

That comparison matters because “light” is relative:

A pickup that can handle 1 yard of dry mulch may be overloaded by 1 yard of topsoil
A truck that has room for 2 yards of mulch may be nowhere near capable of hauling 2 yards of gravel
Wet organic mulch can creep closer to the lighter end of compost weights than many homeowners expect

So mulch is light compared with rock, but not weightless. The gap between 800 pounds of mulch and 2,700 pounds of gravel is huge. The gap between 1,100 pounds of wet mulch and 1,400 pounds of light topsoil is much smaller.

Other Factors: Particle Size, Supplier Practices, and Verification

Type and moisture explain most of the weight differences, but they do not explain all of them.

Particle size and processing

Finer mulch tends to hold more water, and that helps explain why double-ground or finely shredded products often feel heavier after rain than chunkier bark or nuggets. This is supported directly by Mulch Smart KC and indirectly by type-specific ranges from Best Bark Mulch.

Supplier loading practices

Volume itself can vary a bit in practice. The clearest evidence here is anecdotal rather than measured: contractors in a LawnSite forum discussion describe heaped versus level loader buckets and loads that may not be exact, true cubic yards. That does not make the forum a strong authority for density figures, but it does help explain why one “yard” from one supplier may look or feel a little different from a “yard” at another.

Why internet extremes should be treated carefully

That same forum thread stretches from about 400 pounds to 1,700 pounds for a yard of mulch, but those are user estimates, not verified weigh-ticket measurements. So the forum is useful mainly as an anecdotal warning about variability, not as the basis for your main planning number.

How to verify your own load

If you want the most accurate answer for your purchase, generic averages are only the starting point. A practical checklist is:

Ask what the mulch actually is. Hardwood, pine bark, cedar, compost blend, rubber, or something else?
Ask about moisture. Has it been sitting out in the rain, watered down, or freshly processed?
Use the high end if the answer is vague.
Check your actual payload sticker, not just the truck class name.
If the load is close, split the trip.

That approach matches the caution built into the evidence from Chippy Tools, Friendly Tree Service, and Best Bark Mulch.

The bottom line is straightforward: a yard of mulch can be as light as roughly 400 pounds for dry organic mulch or well over 1,200 pounds for saturated or denser materials. If you plan for the wet side, verify the actual product, and compare the load against your vehicle’s real payload rating, you are far less likely to be surprised.

How many bags of mulch equal one cubic yard?

About 13.5 bags of 2-cubic-foot mulch equal 1 cubic yard, usually rounded to 13 or 14 bags, and 9 bags of 3-cubic-foot mulch equal 1 cubic yard, according to Sod Depot, Friendly Tree Service, and Caesar Cipher’s mulch calculator.

What covers 100 sq ft at 3 inches deep?

A 100-square-foot area at 3 inches deep needs about 25 cubic feet of mulch, which is roughly 0.93 cubic yard, according to the worked example in Caesar Cipher’s mulch calculator. That lines up with the standard rule that 1 cubic yard covers about 108 square feet at 3 inches deep, per Sod Depot and Pro Mulch Calculator.

Can my half-ton pickup haul 2 yards of mulch?

Sometimes by volume, yes; by weight, not always. A supplier bed-capacity guide says a standard 6-foot bed can hold about 2 yards of mulch by space, according to Mulch Barn Supply. But 2 yards of wood mulch can weigh about 800 to 1,600 pounds dry and roughly 1,600 to 2,000+ pounds wet, based on per-yard ranges from Friendly Tree Service, Pro Mulch Calculator, and Best Bark Mulch. Since many half-ton trucks fall somewhere around 1,000 to 2,000 pounds of payload, 2 wet yards is often too much. The deciding number is the payload sticker on your specific truck, not the “half-ton” label.

Why is rubber mulch heavier but more predictable?

Because it is commonly listed around 800 to 1,200 pounds per cubic yard, but unlike wood mulch, it does not absorb much water, so wet weather does not change its weight nearly as much. That pattern appears consistently in Best Bark Mulch, Best Bark Mulch’s dry-vs-wet guide, and Pro Mulch Calculator. Organic mulch is often lighter when dry, but much less predictable after rain.

How much heavier is wet mulch than dry?

A common rule of thumb is 30% to 50% heavier, according to Mulch Smart KC and Best Bark Mulch. Some sources suggest bigger jumps are possible: Pro Mulch Calculator says wood mulch can be 50% to 80% heavier when wet, and Best Bark Mulch’s dry-vs-wet article gives a hardwood example rising from about 550 pounds dry to 900 pounds wet, or roughly 60% to 70% heavier.
