Deciding how much sand you need to complete your horse arena can be a difficult, intimidating task.
Order too much and you end up overspending on the sand itself and on redistributing the leftover sand. Don't order enough and you end up having to spend more money to ship more in. To help you with that, we have this arena sand calculator to help you determine the amount of sand required so that you don't overspend or underestimate how much you actually need.
How to Choose the Proper Horse Arena Sand Depth
There are all different types of materials that you can implement in your arena depending on what materials are readily available near your location. One of the most common materials is river sand, but there are other sands you can choose too. Particle size and shape are two of the most important factors when considering which type of sand to choose. Once you pick your primary footing material, you need to determine how much you will need.
This is where things get a little tricky because there are no exact rules for the depth of your arena. Our equestrian advisory board — including FEI-level riders, certified arena builders, and sand science specialists — recommends starting with two inches of sand and adding more in half-inch intervals as needed. For arenas specifically designated for driving, you can start with 1.5 inches, and you generally shouldn't go above 6 inches.
Depth varies by discipline — our advisors note that the cushion can range from about one to two inches for a dressage or jumper horse to six or more inches for reining and cutting horses. That's why every ArenaSpec™ assessment starts with understanding your discipline, climate, and usage before recommending a depth.
How Much Sand Should I Get?
Once you decide on a depth that works for you, you must determine how much sand you will actually need. Providers will offer sand in measurements such as cubic yards and pounds. Here is a step by step process that you can use to determine the number of cubic yards you will need for your arena, or you can simply plug your numbers into our calculator.
Determine the Area
To determine the area of your arena, you will need to multiply the length by the width. You can do this calculation in feet or yards, and the answer will be the area in cubic feet or cubic yards.
Determine the Depth
This number depends on what practices you will host in your arena. You should probably not go above six inches, and it is better to start with less and add more.
Multiply Area × Depth
Before you do this calculation, make sure that the depth and area are both in the same units — either feet, inches, or yards. This will give you the volume.
Convert to Weight
Most material providers can use the volume to find this number. But if your sand provider requires a weight, then you must multiply the volume and the density — a number that varies depending on the type of sand.
Sand Is Only Part of the System
Tonnage tells you how much material to order — but it doesn't tell you whether your surface will actually perform. The right sand depth depends on your base construction, drainage capacity, climate, and how the arena is maintained. A footing system is only as good as the full spec behind it.
That's why Performance Footing starts with a full-system assessment — evaluating your sand, base, and drainage together — before recommending any changes. Sometimes it's a sand correction. Sometimes it's a maintenance adjustment. We find the simplest, most effective path to a surface that supports your horses and your discipline.
