Riding Arenas – Prairie Post Frame

Indoor Riding Arenas

Ride Every Month. Whatever the Weather.

North American winters don't care about your training schedule. An indoor riding arena from Prairie Post Frame gives you the space to ride, train, and run clinics when you want — not just when the weather cooperates.

Why Post-Frame Works for Riding Arenas

Post-frame construction is the proven method for indoor riding arenas across Western Canada. Wide clear spans — we routinely build at 80 feet and beyond — deliver column-free riding surfaces that give horses and riders the full floor to work. No posts to navigate around, no compromised sight lines, no obstructions in jumping lanes or barrel patterns. The structural system that handles large agricultural clear spans is the same one that makes a riding arena perform the way it should.

Size Your Arena Around Your Riding

The right arena dimensions depend on your discipline, how many horses will be in the building at once, and whether you're building for personal use, training, or a commercial equestrian operation. Your PPF rep will work through the layout with you:

60'×100'×20'

General training and pleasure riding, small private operations

70'×140'×20'

Mid-sized facilities with barrel space, roping room, or multiple riders

80'×200'×20'

Full competition, clinic, and show facilities with room for spectators

What Goes Into a Prairie Post Frame Arena

Clear-span column-free interior — the full riding surface, unobstructed

Eave heights from 16' to 20'+ for jumping clearance and show use

Large sliding end-wall doors and entry openings sized for safe horse movement - no tight corners

Translucent polycarbonate light panels (10-year warranty) for natural, shadow-free lighting across the riding surface

Ridge ventilation systems to manage moisture and air quality year-round - critical in an enclosed arena

Insulation options for heated arenas - R28 walls, R40-R60 ceiling packages for year-round conditioning

Solid wood kick planking along lower wall panels for horse and rider safety

Lean-to additions for stall rows, tack rooms, feed storage, wash bays, and viewing areas

Built for Prairie Conditions

A riding arena in Western Canada and Upper Midwest USA faces structural demands a standard building spec won't handle. Prairie Post Frame engineers every arena for your specific location — your regional snow load, prevailing wind direction, frost depth, and local building code. An exposed rural site in Saskatchewan faces different conditions than a site sheltered in Minnesota. We calculate for where your building actually lives, because when a March blizzard hits, that difference is the one that matters.

Build It Right. Build It to Grow.

Most equestrian properties expand over time — more horses, more programming, more use. Prairie Post Frame can design your arena from the start to integrate with existing stall barns or allow for future lean-to additions without compromising the main building.
Stalls, wash bays, tack rooms, viewing galleries, offices, and hay storage can all be planned into the original design or phased in as the operation grows.

Smart Details Make the Difference.

Dust & Ventilation Control

Airflow designed to manage footing dust and air quality for horse and rider.

Clear-Span Interior

Full arena width with zero support posts to interrupt sightlines or riding paths.

Natural & Artificial Lighting Design

Skylights and fixture placement planned for even, glare-free visibility.

Viewing Area & Tack Room Add-Ons

Spectator space or storage integrated without compromising the riding surface.

What size indoor riding arena do I need?

Minimum practical size for general training is 60×120×16. A mid-sized multi-use facility runs 70×160×18. Full competition and show facilities typically start at 80×160×20. Your discipline matters — barrel racing and roping need more length than flatwork, and jumping needs more eave height. Your rep will walk through the specifics based on your horses, your program, and your site.

How does post-frame construction handle the spans needed for a riding arena?

Post-frame is the standard precisely because of span capability. Our in-house truss manufacturing builds trusses engineered to the specific span width of your arena — not pulled from a standard catalogue. We routinely build 80-foot clear spans for riding arenas and scale up from there.

Can a riding arena be heated?

Yes. Heated arenas use R28 wall insulation, R40–R60 ceiling packages, vapour barriers, and in-floor heat provisions or overhead heat systems. Insulating and conditioning an arena requires the full thermal envelope to be designed together — not insulation added to a building designed for cold storage.

What ventilation does an indoor riding arena need?

Arenas generate significant airborne dust and moisture from horse activity. A proper ventilation system uses ridge cap ventilation, curtain wall systems for warm-weather air exchange, and strategic sidewall openings — designed to move air through the building without creating cold drafts at horse level.
