Wedding Table Planner Calculator
Enter your guest count and preferred table size to find out how many tables you need, how many seats will be spare, and how alternative table sizes compare. Accounts for a top table if you have one.
Explain like I'm 5 (why does table planning matter?)
Imagine you have 83 friends coming to dinner and tables that seat 8. You need 11 tables (because 10 tables only seat 80), and you will have 5 empty chairs. That is fine, but it is better to know in advance so the venue can set the room correctly. The tricky part is choosing your table size: smaller tables feel more intimate but you need more of them; bigger tables fit more people but can feel impersonal. This calculator shows you the number of tables for your chosen size, then shows what would happen if you went slightly bigger or smaller, so you can make the call with the actual numbers in front of you.

Alternative table sizes
How the numbers change if you use a different table size for the same guest count.

Prove it
Tables needed = ⌈guests to seat ÷ seats per table⌉ (ceiling, always rounded up). Guests to seat = total guests minus top table guests. Empty seats = (tables × seats per table) minus guests to seat. Alternatives use the same formula with a different seats-per-table value.

Choosing a table size
The most common choice for UK weddings is a round table of 8 or 10. An 8-seat table (typically 5 ft / 150 cm diameter) gives guests comfortable elbow room and makes it easy to talk to everyone at the table. A 10-seat table (6 ft / 180 cm) fits more people but the guests directly opposite each other will struggle to hold a conversation during the meal.
Banquet-style long tables seat 10 to 14 and create a different atmosphere: more family-style, louder, and more social across the full table. They require more linens, more centrepiece planning, and a venue with straight sightlines. Many barn venues and older halls work well with long tables; round-table setups are more common in hotels and licensed venues.
The top table
A top table traditionally seats the couple, their parents, and the principal attendants (best man, chief bridesmaid, maid of honour). It faces the room and is usually a long rectangular table. Top table guests are not counted against the round table allocation; they have their own table. If you are opting for a sweetheart table (just the two of you) or no top table at all, leave the top table field at zero.
Some couples move away from the top table entirely because it separates them from their guests for the whole meal. A round table in the centre of the room, or splitting the couple to host separate tables, are increasingly common alternatives. Neither affects the total table count calculation.
Empty seats: a feature, not a bug
A few empty seats per table is not a problem. It gives guests room for bags, extra place settings for dessert, and the ability to pull chairs back without bumping into their neighbours. Most venues set a table at the stated size regardless; a table of 8 with 7 guests is indistinguishable from the outside. Aim to keep any given table no more than 2 seats short to avoid it looking sparse. If you have a table with 5 or more empty seats, consider redistributing those guests to other tables rather than leaving one table visibly underpopulated.
What to give the venue
Venues need: total guest count, number of tables, table size, and top table configuration. They will also want a seating plan (which guest sits where) typically 2 weeks before the wedding. The table count from this calculator is the number to confirm with the venue when you finalise your contract.

Frequently asked questions
How many guests fit at a round wedding table?
A 5 ft round table seats 8 comfortably; a 6 ft round table seats 10. Squeezing 12 onto a round table is possible but not recommended for a sit-down meal.
What is a top table?
The top table is where the wedding party sits, facing the other guests. It is counted separately from the round or banquet tables. If you have no top table, leave that field at zero.
Is it a problem to have empty seats?
A couple of empty seats per table is normal and gives guests space. Try to keep any one table no more than 2 seats short of its stated capacity.
Should I mix table sizes?
Most venues prefer a consistent table size: it simplifies linen, centrepieces, and room layout. The alternatives table in this calculator shows what each size would look like if used uniformly. If you want to mix sizes, the most common approach is to use a slightly smaller table for one "overflow" group rather than mixing throughout the room.
When do I need to give the venue a final table count?
Most venues ask for a final guest count and table plan 1 to 2 weeks before the wedding. Confirm their specific deadline when you book.
