Frequently Asked Questions

How many chairs fit at a 60-inch round table?

A 60-inch (5-foot) round table comfortably seats 8 guests with adequate elbow room. Maximum capacity is 10 guests, but this is tight and best for casual events where guests know each other.

How many 8-foot tables do I need for 100 guests?

For 100 guests using 8-foot rectangular tables at comfortable capacity (8 per table), you need 13 tables. If using maximum capacity (10 per table), you need 10 tables.

What's the difference between comfortable and maximum table capacity?

Comfortable capacity allows 24 inches per person at the table—enough for formal dining with multiple plates and glasses. Maximum capacity uses 18-20 inches per person—suitable for casual events, cocktail seating, or when space is limited.

How many cocktail tables for a standing reception?

Plan for 1 cocktail table per 10-12 guests at a standing reception. For 100 guests, you'd need 8-10 cocktail tables distributed throughout the space.

Do I need extra chairs beyond guest count?

Yes! Always order 10% extra chairs to account for last-minute guests, damaged chairs, and additional seating needs (service areas, musicians, etc.).
