What are the key wedding planning numbers?
The rules of thumb these calculators use, in one place. They're typical planning guidance — confirm the final numbers with your venue and vendors.

| What size table seats 8? | A 60-inch (5 ft) round, or an 8-ft rectangular banquet table | Table calculator |

| How many guests will come? | About 88% of local guests and 75% of travelling guests; fewer at a destination wedding | Guest count estimator |

About these tools
Are these wedding tools free?
Yes — every tool is free to use, with no sign-up. They give you a straight answer in seconds, and you only create a free account (no credit card needed) if you want to turn that answer into a full seating chart.
Where should I start?
If you're early, start with the guest count estimator to get a working headcount. Then use the table calculator to see how many tables you need, and the room capacity calculator to check it fits your venue.
What size table seats 8 guests?
A 60-inch (5 ft) round table seats 8 guests comfortably (10 at a squeeze), and an 8-foot rectangular banquet table seats about 8. For 10 guests, use a 72-inch round.
How many tables do I need for 100 guests?
13 guest tables if you seat 8 per 60-inch round, or 10 tables at 10 per 72-inch round, plus a head or sweetheart table if you have one. The table calculator works it out for any guest count.
Do the answers carry into the app?
Yes, the seating numbers do. From the table or venue capacity calculator, your guest count, seats per table, table shape, number of tables and head-table choice carry straight into Lovely Seating, so you start with exactly those tables set up. The guest count and budget tools pass your guest count. Room dimensions don't carry over automatically: type them into Room on the floor plan and it's drawn to your venue's real size, in feet or meters.
