How much sand do I need for a horse arena?

Multiply the arena length by width, multiply by the footing depth in feet, then divide by 27 for cubic yards. This calculator also estimates tons using 100 pounds per cubic foot for plain sand, 90 for blended footing, and lets you include a waste factor.

How deep should arena sand be?

Penn State Extension advises starting with about 2 inches of sand and adding half an inch at a time as necessary, and says sand deeper than 6 inches is stressful to horse tendons. This calculator treats plain sand above 4 inches as deeper than usual and flags it.

How many tons is a cubic yard of sand?

For plain sand this estimate uses 1.35 tons per cubic yard, based on 100 pounds per cubic foot. Blended footing is lighter, so the calculator uses 90 pounds per cubic foot, or about 1.22 tons per cubic yard. Confirm the actual mix weight with your supplier.

Estimate based on 100 lb per cubic foot, or 1.35 tons per cubic yard. Confirm final material quantity with your supplier.

Do not forget the base.

Rutgers Extension describes a base of four to six inches of compacted crushed stone under the footing, sloped so water flows across the area and not through the base.

Site caution: soft or wet ground generally calls for a deeper base. The NRCS design guide for aggregate surfacing is linked below.

Choosing the material: read how to pick arena footing and what to ask your supplier.

Work out the base: use the horse arena base calculator for aggregate tonnage.
