About this calculator
Every outdoor wedding needs a rain plan. For a 100-guest seated reception you need roughly a 1,500 sq ft tent (about 30ร50 ft) โ 15 sq ft per guest โ plus sidewalls, flooring and lighting. This Weather Backup Planner sizes your backup tent by guest count and reception style, estimates the 2026 rental cost ($2โ4.50 per sq ft/day), reads the rain risk for your season, and tells you exactly when to make the rain-or-shine call.
Most couples remember the tent but forget the rest of the rain-day kit: flooring on wet grass, fans or heaters, a covered entrance and drop-off, and extra lighting for dark, overcast skies. A canopy alone is not a rain plan โ you need sidewalls.

FAQ
What is a wedding rain contingency plan?
A rain contingency plan is your Plan B if the weather turns on an outdoor wedding. In practice it means a tent with sidewalls (or a booked indoor space) sized to your guest count, plus flooring, lighting, and heating or fans. The key is to reserve it on standby ahead of time and set a clear deadline to make the call โ not to scramble the day before.
How big a tent do I need for an outdoor wedding?
Plan on about 15 sq ft per guest for a seated dinner, ~10 for a cocktail-style reception, and ~8 for a ceremony only. Common sizes for a seated reception:
| Guests | Tent size (seated) | Example dimensions |
|---|---|---|
| 50 | ~750 sq ft | 20ร40 ft |
| 75 | ~1,125 sq ft | 30ร40 ft |
| 100 | ~1,500 sq ft | 30ร50 ft |
| 125 | ~1,875 sq ft | 30ร60 ft |
| 150 | ~2,250 sq ft | 40ร60 ft |
| 200 | ~3,000 sq ft | 40ร80 ft |
Add space if you also need room for a dance floor, buffet, or bar under cover.
When should I decide to move the wedding under a tent or indoors?
Reserve a tent on standby 2โ4 weeks before the wedding โ the good rental companies book up, especially in peak season. Then make the final go/no-go call 24โ48 hours before, when the forecast is reliable. Tent companies typically need 48โ72 hours to schedule setup, so donโt leave the decision to the morning of.
How much does a wedding backup tent cost in 2026?
A frame tent with sidewalls runs roughly $2โ4.50 per sq ft/day in 2026 โ about $3,000โ6,750 for a 1,500 sq ft tent (100 guests), before extras. Budget separately for flooring ($1โ3/sq ft), lighting, and heaters or fans.
Do I still need a rain plan if my venue has an indoor backup?
Usually yes โ confirm the indoor space actually fits your full guest count seated, not just standing. Many venues quote a smaller โbackup room.โ If the indoor option is real and large enough, you may skip the tent, but keep umbrellas and a covered entrance for arrivals.
Whatโs on a wedding rain-day checklist?
Tent with sidewalls (not just a canopy), flooring or turf protection on wet ground, fans (heat) or heaters (cold), umbrellas plus a covered entrance and drop-off, extra lighting for overcast skies, and clear signage so guests know where to go if plans change.
