Work out how much sand your riding arena needs in under a minute. Then check your supplier's sand analysis before you order.
Free. Metric and imperial. A first check only, see the note below.
Pick your arena size, or enter your own length and width, and set the top layer depth.
Footing depends on moisture, and moisture depends on the sand. Too uniform and it lacks grip. Too many fines and it compacts, holds water and gets dusty when it dries.
Upload the supplier's sand analysis and the Sand Agent, a free AI tool, draws the gradation curve against our equestrian range. It's how we checked the sand for a recent arena project in Greece.
Length x width x top layer depth, plus about 10% for compaction. A 20 x 60 m dressage arena at 10 cm needs about 132 m³, roughly 210 tonnes of dry sand.
Top layers are often 10 to 15 cm (4 to 6 in). It depends on the sand, any fibre in the mix and how the arena is watered.
Multiply the volume by the sand's bulk density. Dry sand is typically about 1.6 tonnes per m³; ask your supplier.
No single sand is best. Particle size spread, fines content, grain shape and watering all matter. Check the supplier's analysis before you order.
The recommended ranges are based on industry experience and research and do not guarantee how a sand will perform. Always confirm results with an accredited soil testing laboratory or your sand supplier before ordering or installing sand.
