Horse arena dimensions
The published arena sizes are riding areas, not buildings: a 20 x 60 m dressage arena is 65.6 x 196.9 ft of surface before any perimeter setback is added.
- Small dressage
- 20 × 40 m (65.6 × 131.2 ft)
- Standard dressage
- 20 × 60 m (65.6 × 196.9 ft)
- Setback used
- 2 ft, stated input
- Span needed
- About 70 ft
Quick reference
Published arena sizes and the building around them
Building footprint = riding area + a 2 ft setback on each side
| Arena | Published riding area | In feet | Building footprint | Clear span needed | Where it comes from |
|---|---|---|---|---|---|
| Small dressage arena | 20 × 40 m | 65.6′ × 131.2′ | 69.6′ × 135.2′ | 69.6′ | USDF tests ridden in the small arena |
| Standard dressage arena | 20 × 60 m | 65.6′ × 196.9′ | 69.6′ × 200.9′ | 69.6′ | FEI standard arena; also used for USDF tests |
Riding areas are published FEI and USDF dimensions. The setback is a stated planning input, not a governing-body requirement.

Riding area inside the building line
An 80 x 200 building with a 2 ft setback leaves 76 × 196 ft of riding surface, or 14,896 sq ft.
Planning
Arena width is a clear span question
A riding surface is only usable if nothing stands in it, so the width you need is a clear span: 65.6 ft of dressage arena plus setback means asking for a span in the region of 70 ft, not a 70 ft wide building with a centre column. Ask for the span figure explicitly when you request quotes — it is the number that changes the price most.
Discipline requirements against building geometry
- Fits
Lunging circle only
A 60 ft span carries a standard lunging circle with room at the edge.
- Fits
USDF small arena, 20 × 40 m
65.6 × 131.2 ft of surface; a 70 ft span clears it with the stated setback.
- Fits
FEI standard arena, 20 × 60 m
65.6 × 196.9 ft of surface; the length, not the span, is what grows.
- Marginal
Spectator seating inside the same span
Seating takes width out of the riding surface. Add it to the footprint, not to the arena.

Common questions
USDF tests are ridden in an arena of either 20 x 40 m or 20 x 60 m, and the FEI standard arena is 60 x 20 m. In feet that is 65.6 x 131.2 and 65.6 x 196.9.
Larger than the riding area. This page adds a stated 2 ft setback on each side, which puts a standard arena inside a building of roughly 70 x 201 ft.
For a usable riding surface, yes — a column inside the arena takes the surface out of use. Ask suppliers for the clear span figure explicitly rather than the building width.
