  • Tent with sidewalls (not just a canopy)
  • Flooring or turf protection on wet ground
  • Fans (heat) or heaters (cold) on standby
  • Umbrellas + a covered entrance/drop-off
  • Lighting — overcast skies get dark early
  • A clear indoor Plan B if a tent isn't possible

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 30×50 ft) — 15 sq ft per guest — plus sidewalls, flooring and lighting. This Weather Backup Planner sizes your backup tent by guest count and reception style, estimates the 2026 rental cost ($2–4.50 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 — 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 — 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 20×40 ft
75 ~1,125 sq ft 30×40 ft
100 ~1,500 sq ft 30×50 ft
125 ~1,875 sq ft 30×60 ft
150 ~2,250 sq ft 40×60 ft
200 ~3,000 sq ft 40×80 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 2–4 weeks before the wedding — the good rental companies book up, especially in peak season. Then make the final go/no-go call 24–48 hours before, when the forecast is reliable. Tent companies typically need 48–72 hours to schedule setup, so don’t leave the decision to the morning of.

How much does a wedding backup tent cost in 2026?

A frame tent with sidewalls runs roughly $2–4.50 per sq ft/day in 2026 — about $3,000–6,750 for a 1,500 sq ft tent (100 guests), before extras. Budget separately for flooring ($1–3/sq ft), lighting, and heaters or fans.

Do I still need a rain plan if my venue has an indoor backup?

Usually yes — confirm the indoor space actually fits your full guest count seated, not just standing. Many venues quote a smaller “backup room.” If the indoor option is real and large enough, you may skip the tent, but keep umbrellas and a covered entrance for arrivals.

What’s 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.
