How much space do I need for a tent wedding?

I’m hosting an outdoor wedding for 80 guests and I’m looking at those flexible stretch canopies. I need to fit a bar, a lounge area, and dinner tables. How do I calculate the exact dimensions so it’s not too cramped but still looks cozy?

Honestly, planning the layout is the most important part. I used to guess the dimensions until I found a really helpful guide on stretch tent sizes that explained the difference between seated and standing capacity. You can check it out here. Following their advice saved my last party because I realized I needed a much bigger setup than I initially thought!
