So, how much does a yard of bark weigh? The simple answer is: it depends a lot, but a cubic yard of bark usually weighs between 400 and 1,500 pounds. This wide range happens because many things change the weight. Things like the type of tree the bark came from, how much water is in it, and how fine or chunky the pieces are make a big difference. This is the weight of bark mulch per yard. It’s also how many pounds in a yard of mulch, using a common unit like the cubic yard bark weight. Landscaping bark weight is never just one number.

Grasping Why Bark Weight Varies
Bark is not all the same. Its weight changes a lot from one pile to another. This is because of several key things. Knowing these things helps you guess closer to the real weight. It helps when you order bark for your garden or yard work.
Moisture Content Makes a Big Difference
This is likely the most important thing that changes bark weight. Dry bark is much lighter than wet bark. Bark that has been sitting outside in the rain will soak up water. Water is heavy. One gallon of water weighs about 8.34 pounds. Bark can hold a lot of water. A cubic yard of wet bark might weigh twice as much as the same amount of dry bark. Think about bark delivered on a sunny day versus after a big rainstorm. The wet bark load will be much heavier.
The Type of Tree Matters
Different trees have different kinds of bark. Pine bark is common. Cedar bark is also used. Hardwood barks come from trees like oak or maple. Each type of bark has a different natural density. Density is how much stuff is packed into a certain space. This is the density of bark mulch. A cubic yard of mulch density changes with the wood type.
* Pine bark often weighs less than hardwood bark when dry.
* Cedar bark is often lighter than many other types.
* Hardwood bark can be heavier.
So, the weight of different types of bark is not the same.
Size and Shape of the Bark Pieces
Bark mulch comes in different sizes.
* Fine shredded bark has small pieces.
* Bark nuggets are bigger chunks.
Loose bark means pieces are not packed tight. Compacted bark means pieces are pressed together.
* Fine shredded bark might settle more and pack tighter, especially when wet. This could make a cubic yard heavier than if it was loose.
* Bark nuggets are often larger and have more air space between them. This can make a cubic yard of nuggets lighter than a yard of shredded bark, assuming they are equally dry or wet.
How Much Air is in the Pile
The way the bark is piled or measured matters. A cubic yard is a measure of volume, like a box that is 3 feet wide, 3 feet long, and 3 feet high. How much bark you can fit in that box depends on how much air is mixed in. If the bark is very loose, there is more air. If it is packed down, there is less air and more bark material. This affects the weight per cubic yard. A loosely loaded truck might weigh less than a tightly packed one, even if they both hold a “cubic yard” by volume.
Exploring Different Types of Bark and Their Weights
As we said, the kind of tree changes the bark’s weight. Here are some common types of bark mulch and what they might weigh per cubic yard. Keep in mind these are just guides. The real weight will still change based on how wet they are and other factors.
Pine Bark
Pine bark is popular. It’s often used in gardens. It comes in different forms:
* Pine Bark Fines: These are small pieces, almost like sawdust. They can pack tightly.
* Pine Bark Mini-Nuggets: These are small chunks.
* Pine Bark Large Nuggets: These are bigger chunks.
Pine bark is usually lighter than many other types of wood bark.
* A dry cubic yard of pine bark might weigh about 400 to 600 pounds.
* A wet cubic yard could weigh 800 to 1200 pounds or more.
This is part of the landscaping bark weight you might see.
Cedar Bark
Cedar bark is another popular choice. It smells nice and lasts a long time. Cedarwood itself is lighter than many other woods. Cedar bark is often relatively light too.
* A dry cubic yard of cedar bark might weigh around 500 to 700 pounds.
* A wet cubic yard could be 900 to 1300 pounds.
It falls within the common range for weight of bark mulch per yard.
Hardwood Bark
Hardwood bark comes from trees like oak, maple, or mixed hardwoods. It tends to be heavier than pine or cedar bark. It often breaks down more slowly.
* A dry cubic yard of hardwood bark might weigh 600 to 800 pounds.
* A wet cubic yard could easily be 1000 to 1500 pounds or even more if very wet.
This shows how much the weight of different types of bark can vary.
Composted Bark
Sometimes bark is composted, meaning it’s allowed to break down partly. This process can change its weight. Composted bark might be finer and hold moisture differently than fresh bark. Its weight will depend on how much it’s composted and its moisture level. It often falls in a similar range to hardwood bark due to holding moisture.
Deciphering Bark Density
Density tells us how much mass is in a certain volume. For bark mulch, we often talk about pounds per cubic foot or pounds per cubic yard. This is the density of bark mulch or the cubic yard of mulch density.
* If bark is dense, it means there’s a lot of bark material packed into a small space. It weighs more per cubic yard.
* If bark is not dense (less dense), it means there’s more air space. It weighs less per cubic yard.
Bark mulch weight per cubic foot is just the total weight of a cubic yard divided by 27 (because there are 27 cubic feet in one cubic yard). If a cubic yard weighs 675 pounds, then the weight per cubic foot is 675 / 27 = 25 pounds per cubic foot.
Dry, less dense bark (like some types of dry pine fines) might have a density around 15-20 pounds per cubic foot. Wet, dense bark (like wet hardwood bark) could have a density of 40-55 pounds per cubic foot.
This difference in density is why the cubic yard bark weight changes so much.
Converting Bark Volume to Weight (and Vice Versa)
You often buy bark by the cubic yard. But you might need to know the weight for a few reasons:
* To figure out if your truck or trailer can carry the load safely.
* To estimate delivery costs, which might be based on weight.
* To compare costs if one supplier sells by weight and another by volume.
Converting bark volume to weight is not exact because of the factors we talked about. But you can make a good guess.
You need to know:
1. The volume (how many cubic yards you have or need).
2. An estimated weight per cubic yard for the type of bark you are using and its likely moisture level.
Let’s say you need 5 cubic yards of pine bark that seems moderately wet. You estimate a wet cubic yard of pine bark weighs about 1000 pounds.
* Total estimated weight = 5 cubic yards * 1000 pounds/cubic yard = 5000 pounds.
If you bought bark by weight, say 3000 pounds of hardwood bark, and you want to guess the volume. You estimate a moderately dry hardwood cubic yard weighs 700 pounds.
* Total estimated volume = 3000 pounds / 700 pounds/cubic yard = about 4.3 cubic yards.
Remember, these are just estimates. The real numbers might be different.
Table of Estimated Bark Weights Per Cubic Yard
Here is a simple table showing rough weight ranges for common types. These are just estimates.
| Type of Bark | Approx. Dry Weight (pounds/cubic yard) | Approx. Wet Weight (pounds/cubic yard) |
|---|---|---|
| Pine Bark | 400 – 600 | 800 – 1200+ |
| Cedar Bark | 500 – 700 | 900 – 1300+ |
| Hardwood Bark | 600 – 800 | 1000 – 1500+ |
| Composted Bark | 550 – 750 | 900 – 1400+ |
This table gives a quick look at the weight of different types of bark. The weight of bark mulch per yard changes a lot based on these factors.
Practical Uses for Knowing Bark Weight
Knowing about bark weight helps you plan better for your landscaping projects.
Figuring Out Delivery and Hauling
If you are picking up bark yourself, you need to know your vehicle’s hauling limit. Check your truck or trailer’s gross vehicle weight rating (GVWR) or payload capacity. This number tells you the most weight your vehicle can safely carry, including the weight of the truck itself, you, passengers, and the load.
* A typical half-ton pickup truck can carry around 1000-2000 pounds in its bed.
* A typical quarter-ton truck (smaller) carries less, perhaps 500-1000 pounds.
* Larger trucks (3/4 ton, 1 ton) carry more.
If you need 5 cubic yards of wet hardwood bark, which could weigh 7500 pounds (5 * 1500 lbs), you cannot haul this in one trip with a half-ton truck. You would need many trips or a bigger truck or a delivery service. Knowing the weight helps you avoid overloading your vehicle, which is dangerous and can damage your truck.
Estimating Project Costs
Sometimes bark is sold by the cubic yard, sometimes by the ton (2000 pounds). Knowing the likely weight per cubic yard lets you compare prices better.
* Supplier A sells pine bark for $40 per cubic yard.
* Supplier B sells the same type of pine bark for $90 per ton.
Let’s assume moderately dry pine bark weighs 500 pounds per cubic yard.
* How many cubic yards are in one ton? 1 ton = 2000 pounds. 2000 pounds / 500 pounds/cubic yard = 4 cubic yards per ton.
* Price per cubic yard from Supplier B = $90 per ton / 4 cubic yards per ton = $22.50 per cubic yard.
In this example, Supplier B is cheaper per cubic yard ($22.50 vs $40), even though the price per ton seems higher at first glance. Converting bark volume to weight (or weight to volume) helps you find the best deal.
Planning How Much You Need
You calculate the area you want to cover with bark. You decide how deep you want the bark layer (often 2-4 inches). This tells you the volume of bark needed in cubic feet or cubic yards.
* Area in square feet * Depth in feet = Volume in cubic feet.
* Volume in cubic feet / 27 = Volume in cubic yards.
Once you have the volume in cubic yards, knowing the estimated cubic yard bark weight lets you figure out the total weight. This helps with the hauling or delivery planning we just talked about. It connects the landscaping bark weight to your actual needs.
Calculating What You Need in More Detail
Let’s walk through how to figure out the volume of bark you need. This is step one before thinking about weight.
Measure Your Area
First, measure the space where you want to put the bark. Use a tape measure.
* If the area is a rectangle or square, measure the length and the width. Multiply length by width to get the area in square feet. (Length * Width = Area in sq ft).
* If the area is a circle, measure the distance across the middle (diameter). Divide that by 2 to get the radius. Multiply radius by itself, then by 3.14 (pi). (Radius * Radius * 3.14 = Area in sq ft).
* For odd shapes, you can try to break them down into smaller rectangles or squares, measure each part, and add the areas together.
Example: You have a garden bed that is 20 feet long and 5 feet wide.
* Area = 20 ft * 5 ft = 100 square feet.
Choose Your Depth
How deep do you want the layer of bark?
* For stopping weeds, a 2-3 inch layer is often good.
* For moisture retention and a neat look, 3-4 inches is common.
* If you are putting it over bare soil, maybe a little deeper (4 inches) to help block weeds.
* If you are adding a thin layer over existing mulch, maybe 1-2 inches.
It’s best to work with feet for calculations. Convert your chosen depth from inches to feet.
* Depth in feet = Depth in inches / 12
Example: You want a depth of 3 inches.
* Depth in feet = 3 inches / 12 inches/foot = 0.25 feet.
Calculate Volume in Cubic Feet
Now multiply the area (in square feet) by the depth (in feet).
* Volume in cubic feet = Area in sq ft * Depth in ft.
Example: 100 square feet area * 0.25 feet depth = 25 cubic feet.
Convert Volume to Cubic Yards
Bulk materials like bark are usually sold by the cubic yard. There are 27 cubic feet in one cubic yard (3ft * 3ft * 3ft = 27 cubic feet).
* Volume in cubic yards = Volume in cubic feet / 27.
Example: 25 cubic feet / 27 cubic feet/cubic yard = about 0.93 cubic yards.
So, for that example garden bed, you need a little less than one cubic yard of bark.
Estimate the Weight Based on Volume
Now that you know the volume (about 0.93 cubic yards), you can estimate the weight. Let’s say you want to use hardwood bark, and it’s going to be delivered after some rain (wet). From our table, wet hardwood bark might weigh 1000-1500 pounds per cubic yard. Let’s use an average of 1250 pounds per cubic yard for a rough guess.
* Estimated total weight = Volume in cubic yards * Estimated weight per cubic yard.
* Estimated total weight = 0.93 cubic yards * 1250 pounds/cubic yard = about 1163 pounds.
Knowing this helps you plan if you need delivery or if you can haul it yourself.
How Weather Affects Bark Weight After Delivery
Even after you buy and place the bark, its weight can change.
Rain Adds Weight
If it rains on your bark pile or after you spread it, the bark will get heavier. It soaks up water. This extra weight is not usually a problem once the bark is spread out, but it’s why a fresh delivery after rain weighs so much more.
Drying Reduces Weight
On sunny, dry days, water will leave the bark. The bark will get lighter as it dries out. This is a slow process. The bottom layers of a thick mulch bed might stay wet for a long time.
Seasonal changes affect bark weight naturally in the supply yard. Bark stored outside in summer will likely be drier and lighter than the same type of bark stored outside in fall or winter.
Contrasting Bark and Wood Chips
The request mentioned the weight of wood chips too. While this post is mostly about bark, it’s good to know how they compare. How much does a cubic yard of wood chips weigh?
Wood chips come from the inner wood of trees, not just the bark. They are often made from whole trees or branches ground up. Like bark, the weight of wood chips varies based on:
* Type of wood: Hardwood chips (oak, maple) are heavier than softwood chips (pine, fir).
* Moisture content: Wet chips are much heavier than dry chips.
* Size of chips: Finer chips can sometimes pack tighter than coarser chips.
In general, wood chips can have a similar weight range to bark mulch, or sometimes be slightly heavier if made from dense hardwoods and are very wet.
* A dry cubic yard of wood chips might weigh 500 to 800 pounds.
* A wet cubic yard of wood chips could weigh 1000 to 1800 pounds, or sometimes more for very dense, wet wood.
So, the weight of bark mulch per yard and the weight of wood chips per yard are both highly variable due to similar reasons, mainly moisture and wood type.
Tips for Getting Bark
Here are some ideas when you are ready to buy bark:
- Ask the Supplier: The best way to know the weight is to ask the place you are buying from. They often have an idea of the average weight per yard for the specific product they sell. Ask if it’s dry or wet.
- Consider Delivery: If you need many cubic yards, delivery is often easier and safer than hauling it yourself. The delivery fee might be worth avoiding multiple trips and the risk of overloading your vehicle.
- See the Product: If possible, look at the bark before you buy. Does it look wet? Are the pieces large nuggets or fine shreds? This helps you guess the moisture level and type, which affects weight.
- Confirm Volume: Make sure you understand how the supplier measures a cubic yard. Is it a packed loader bucket or a measured box? This affects how much bark you actually get.
Final Thoughts on Bark Weight
The weight of a cubic yard of bark is not a fixed number. It changes a lot. The main reasons are how much water is in it (moisture), the type of tree it came from (like pine or hardwood), and the size of the bark pieces. A typical range for cubic yard bark weight is 400 to 1500 pounds.
Knowing this helps you plan projects better. You can figure out if your truck can handle the load. You can compare prices fairly if they are given in different ways (by volume or by weight). You can estimate the total weight you will be working with. Always ask your supplier for their best estimate of the weight for the specific bark product you want to buy. This gives you the most helpful information for your needs.
Frequently Asked Questions (FAQ)
How many pounds are in a yard of mulch?
A cubic yard of mulch (which is often bark) usually weighs between 400 and 1500 pounds. The exact weight depends mostly on how wet it is, the type of wood it came from, and the size of the pieces.
What is the average weight of a cubic yard of bark?
There isn’t one single average, but a common range people use for estimating is 600-800 pounds per cubic yard for moderately dry bark. However, remember it can be much lower (400 lbs for dry pine) or much higher (1500+ lbs for wet hardwood).
Does wet bark weigh a lot more than dry bark?
Yes, absolutely. Water is heavy. Wet bark can easily weigh twice as much as the same amount of dry bark. Moisture content is the biggest factor affecting bark weight.
Is pine bark lighter than hardwood bark?
Generally, yes. Pine is a softwood tree. Its bark is typically less dense than bark from hardwood trees like oak or maple when both are equally dry.
How much does bark mulch weigh per cubic foot?
A cubic yard has 27 cubic feet. To find the weight per cubic foot, you divide the weight of a cubic yard by 27. If a cubic yard weighs 675 pounds, one cubic foot weighs 25 pounds (675 / 27). Bark mulch weight per cubic foot ranges roughly from 15 to 55 pounds depending on density and moisture.
How do I figure out how much bark I need?
You measure the area you want to cover (length times width for a rectangle, in feet). Then decide on the depth you want (in inches, then convert to feet by dividing by 12). Multiply the area (sq ft) by the depth (ft) to get volume in cubic feet. Divide cubic feet by 27 to get cubic yards.
Why is weight important if I buy bark by the yard?
Knowing the estimated weight helps you plan for hauling or delivery. You need to know if your vehicle can safely carry the weight or if you need to arrange delivery. It also helps you compare prices if some suppliers sell by weight (like the ton) instead of by volume (the cubic yard).
Does shredded bark weigh more than bark nuggets?
It can depend on how much air is in the pile. Shredded bark can sometimes pack down more, especially when wet, which might make a cubic yard weigh more than a yard of loosely piled nuggets of the same wood type and moisture level.
How much does a cubic yard of wood chips weigh compared to bark?
Wood chips often have a similar weight range to bark mulch. Like bark, their weight changes a lot with the type of wood and moisture level. Dense, wet wood chips can be quite heavy, sometimes even heavier than bark from the same type of tree. A range is often 500-1800+ pounds per cubic yard.
