Quick answer: Landscape rock is usually sold by weight, in tons, or by volume, in cubic yards. Which one you use depends on the material and the supplier, and both come down to how much area your rock will cover at the depth you want. Once you know your square footage and depth, you can figure out how much to order and arrange delivery or pickup.
If you have started pricing out a rock project, you have probably seen material listed by the ton in one place and by the cubic yard in another, which can be confusing. The good news is that it is simpler than it looks once you understand what each unit means and how it connects to the area you are covering. Here is how landscape rock is sold and how to plan your order.
Sold by the ton versus the cubic yard
There are two common ways rock is measured. A ton is a measure of weight, and a cubic yard is a measure of volume, meaning the space the rock takes up. Bulk decorative rock and gravel are often sold by the ton, while soils, sands, and mulch are frequently sold by the cubic yard. The important thing is that both are just different ways of answering the same question: how much material do you need to cover your yard at the depth you want. A supplier can help you translate between the two.
How coverage connects to what you order
The amount of rock you need comes down to three things: the length and width of the area, and the depth you want the rock to be. Multiply length by width to get your square footage, then factor in depth, since deeper rock uses more material per square foot. Most decorative ground cover is spread about two to three inches deep. Once you know your square footage and depth, you can work out the quantity, and our landscape rock coverage guide walks through the simple math.
Rock size affects how far it goes
The size of the rock changes how it covers an area. Finer gravel packs tightly and spreads a bit further, while larger cobble and accent rock leave more space between pieces and can require a touch more depth to fully hide the ground. If you are not sure which size fits your project, our post on what size gravel to use for different projects breaks it down, and you can compare materials in our decorative rock collection.
How rock delivery works
For most yards, bulk rock is delivered loose and dropped in a spot you choose, such as a driveway, from which you move it into place. Because rock is heavy, delivery saves you from hauling many loads yourself, and it is usually the easiest option for a full yard. Smaller projects can be picked up in person if you prefer. When you plan delivery, it helps to have a clear, accessible drop spot and to know roughly how much material is coming so you are ready to spread it.
How to plan your rock order
- Measure the length and width of each area you want to cover.
- Choose your depth, commonly two to three inches for ground cover.
- Use your square footage and depth to estimate the quantity, or ask us to help.
- Pick your material and size, keeping in mind how each covers an area.
- Decide on delivery or pickup, and prepare a clear drop spot for a delivery.
Bagged rock versus bulk rock
For small touch up jobs, decorative rock is sometimes available in bags, which are easy to carry and handy for a planter or a tiny area. For anything larger, bulk rock is far more practical and economical by volume, since covering a real yard from bags would take a great many of them. Most full yard projects use bulk material delivered loose, with bagged rock saved for minor accents or repairs.
How to avoid ordering too much or too little
The best way to order the right amount is to measure carefully and confirm your depth before you buy. Account for the full area, including any odd shaped sections, and plan for a consistent depth throughout. A small buffer helps you finish edges and top up settling, while ordering far too much leaves you storing or hauling away excess. When in doubt, share your measurements with us and we will help you land on the right quantity.
Frequently Asked Questions
Is landscape rock sold by the ton or by the yard?
Both are common. Bulk decorative rock and gravel are often sold by the ton, while soils, sands, and mulch are frequently sold by the cubic yard. Both come down to covering your area at the depth you want, and a supplier can help you convert between them.
How much area does a ton of rock cover?
It depends on the rock size and the depth you spread it. Finer gravel at a shallower depth covers more area than larger rock spread deeper. Knowing your square footage and target depth is the best way to estimate, and our team can help.
How is bulk rock delivered?
Bulk rock is usually delivered loose and dropped in an accessible spot you choose, such as a driveway, and you move it into place from there. Delivery saves hauling heavy loads yourself, which is why most homeowners prefer it for larger projects.
Can I pick up rock myself instead of having it delivered?
Yes. Smaller projects are often picked up in person from our Henderson yard. For a full yard, delivery is usually easier because of the weight involved.
