Every capacity number you'll be given is really two numbers: what fits, and what fits comfortably. Venues quote the first. Your guests experience the second.
Round tables
48 inches (4ft) — seats 6. Comfortably 6. Common for smaller venues and children's tables.
60 inches (5ft) — seats 8, or 10 at a squeeze. This is the standard wedding table, and the one most venues have. Eight is comfortable. Ten means elbows.
66 inches (5.5ft) — seats 10. Less common but a genuinely good size.
72 inches (6ft) — seats 10, or 12 at a squeeze. Ten is comfortable.
The rule of thumb underneath: allow about 24 inches of table edge per person.
Rectangular banquet tables
6ft (72 in) — seats 6 to 8 depending on whether you seat the ends.
8ft (96 in) — seats 8 to 10.
Long banquet-style rows are made by pushing these together. When you do, remember that the joins swallow the end seats, so two 8ft tables in a row seat fewer than two separate 8ft tables.
What the numbers don't tell you
Centrepieces. A tall arrangement takes no place settings but blocks sightlines across the table. A wide low one takes real estate. Check the footprint before you commit to a table size.
Menu style. Family-style service, with platters on the table, needs meaningfully more room. If food is being shared rather than plated, drop one seat per table.
Chair width. Chiavari chairs are narrow. Upholstered or armed chairs are not, and can cost you a seat.
Space between tables. You need about 60 inches between table edges for guests and servers to pass. Venues sometimes quote a table count that assumes less than this. Ask.
Working out how many tables you need
Take your guest count, divide by your comfortable capacity, round up.
130 guests at 8 per table is 16.25, so 17 tables.
Then look hard at the remainder. Seventeen tables where the last one has two people at it is a problem you want to solve now, not on the day. Your options are to spread the overflow across other tables, drop to a smaller number of larger tables, or accept one deliberately smaller table and seat it well.
Mixing table sizes
You don't have to use one size throughout, and mixing often solves the awkward-remainder problem neatly. A common arrangement is mostly 60-inch rounds with one or two long banquet tables for the wedding party and larger family groups.
The one thing to avoid is mixing sizes randomly, which reads as accidental. Mixed sizes look deliberate when there's a visible logic to them.
Head tables
A traditional head table seats on one side only, so an 8ft table seats 4 or 5 rather than 8 to 10. Budget accordingly — a wedding party of ten needs two full-length tables, not one.
A sweetheart table for two is usually a 36 or 48-inch round, or a small rectangle.
The Seating Room lets you set the seat count per table and shows you at a glance which tables are full, which have gaps, and how many guests are still unseated. Free to plan.
