Planning Tips

  • Book early: Reserve 6-12 months ahead for peak wedding season (May-October). Popular tent sizes sell out.
  • Check the ground: The site needs to be flat and clear. Tent companies need to stake into the ground or use weights on hard surfaces.
  • Consider the weather: Add sidewalls for rain protection. For hot weather, factor in fan or AC rental. For cold weather, add heaters.
  • Permits: Many municipalities require permits for tents over 400 sq ft. Check local regulations 2-3 months before.
  • Power: Generators are needed for lighting, sound, and catering equipment if the site does not have power. Budget $200-$500 for generator rental.

FAQ

What size tent do I need for 100 guests?

For a seated dinner with 100 guests, you need approximately1,350 sq ft — a 30' x 45' tent. For cocktail style, a 30' x 30' (900 sq ft) works. For ceremony only, a 20' x 40' (800 sq ft) is sufficient.

What is the difference between a pole tent and a frame tent?

Pole tentsuse center poles and are staked into the ground — they are cheaper but need soft ground and have interior poles. Frame tentsuse an aluminum frame with no center poles — they work on any surface and give you full interior space, but cost 30-50% more.

Do I need a tent for an outdoor wedding?

Even if the forecast is clear, always have a tent or backup plan. Weather is unpredictable, and tents also provide shade from sun and protection from wind. Most wedding planners consider a tent essential for outdoor events.
