Start with seating style
For 50 guests, the table count depends on whether you want small round-table conversations, long shared dining or a mix of seated and standing spaces.
A common starting point is five round tables seating about ten guests each, but the exact mix changes with table size, catering and available floor space.
Use trestle tables for flexibility
Trestle tables can be arranged as long banquet lines, used for food service or split between dining and gift-table zones. They are often useful when the venue is narrow or the backyard layout is rectangular.
Leave enough circulation room
Do not plan furniture to the edges of the room. Leave space for chairs to move, guests to pass and catering to work safely.
