How Many Tables and Chairs Do I Need for My Event?

Working out tables and chairs from a guest list sounds simple until you actually try to do it, because the answer depends on which table style you choose, how many people you seat per table, and whether you're leaving room for a head table, a gift table or a buffet line. Here's how to get from a guest count to an accurate hire order without the usual over-ordering or last-minute scramble for extra chairs.

Table sizes and seating capacity

The two table types almost every Australian hire company stocks are round tables and trestle (rectangular) tables, and each seats a different number depending on size:

• 1.5m round table: seats 8 comfortably.
• 1.8m round table: seats 10, the standard choice for a formal seated wedding or gala dinner.
• 1.8m (6ft) trestle table: seats 6 with people only down the long sides, or 8 if you also seat guests at each end. Trestles are cheaper to hire than rounds and pack down flatter, which is part of why they're the default for casual and budget events.
• 1.2m (4ft) trestle table: seats 4 to 6, useful for smaller groupings, kids' tables or a buffet and gift table rather than main dining.

Round tables generally give a better conversation dynamic for a formal dinner, since everyone can see everyone else, while trestle tables in long banquet rows suit a casual, communal-style event and use floor space more efficiently for a given guest count.

Working out the numbers

Start with your confirmed guest count, then divide by your chosen table's seating capacity and round up, not down. A few worked examples:

• 64 guests on 1.8m rounds (seats 10): 64 divided by 10 is 6.4, so round up to 7 tables. That leaves a few empty seats spread across the room, which is normal and better than a table that's genuinely full with no room to move.
• 50 guests on 1.5m rounds (seats 8): 50 divided by 8 is 6.25, so round up to 7 tables.
• 80 guests on 1.8m trestles (seats 8, both ends used): 80 divided by 8 is 10 trestle tables.

Don't force every table to its maximum. A table technically seating 10 with elbow-to-elbow guests photographs and feels worse than the same table seating 8, so many event planners deliberately under-fill by one or two seats per table on rounds for exactly that reason, which means ordering slightly more tables than the strict maths suggests if presentation matters to you.

Chairs: order a few more than your guest count

Chair numbers should match your guest count, but it's worth ordering 3-5% extra as spares, covering last-minute plus-ones, a chair that arrives damaged, or extra seating for vendors and helpers who end up needing somewhere to sit. For a 100-guest event, that's about 4-5 spare chairs, a small extra cost against the cost of running short on the day.

If any part of the event needs different seating, factor it in separately: a ceremony commonly uses different chairs (or none, if it's standing) to the reception, and kids' tables need smaller chairs sized for children, not a scaled-down adult chair.

Linen and place settings

Table linen is usually counted per table, not per guest: one tablecloth per table as a baseline, plus table runners or overlays if you're layering the look, which some suppliers charge per table and some per metre depending on the style. Napkins, on the other hand, are counted per guest along with cutlery and glassware if you're hiring those separately from your caterer. If you've settled on a table count already, that number carries straight across to your linen order, so lock in tables first.

Cocktail and standing events count differently

A standing cocktail event doesn't need a chair count at all, but it still needs a table count: cocktail (bar-height) tables are typically ordered at a rate of roughly one table per 8-12 guests, enough for small groups to rest a drink and a plate without every guest needing a seat. A mixed event, part seated dinner and part standing cocktail hour, needs both counts worked out separately rather than one number covering the whole night, since the seated dinner count and the cocktail table count are answering two different questions.

Kids' tables and buffet layouts

If children are attending, a kids' table with smaller chairs sized for them is worth booking separately rather than seating children at adult-height tables with adult chairs, both for comfort and so the smaller chairs don't get counted (and paid for) as part of your main adult seating order. If catering is buffet-style rather than plated, the buffet or servery table itself is a separate booking again, usually a couple of trestle tables end to end, and it needs to be planned into the floor layout so the queue doesn't cut across the main seating area.

Don't forget the space, not just the count

Table and chair numbers only work if the room or marquee is actually big enough to fit them with walking space between tables, a dance floor if you want one, and room for a buffet or bar. If you haven't sized your marquee yet, the marquee size guide walks through turning a guest count into a floor area, and it's worth doing that step before finalising your table layout so the two numbers agree with each other. If this is for a wedding specifically, the wedding hire checklist covers the full run of what to book and roughly when.

Skip the manual maths

If you'd rather not work through the divide-and-round-up maths by hand for every table style you're considering, the guest seating calculator takes your guest count and preferred table type and returns table numbers, chair counts and a linen count in one go.

Confirm with your supplier before you order

These numbers are a solid starting point, not a substitute for confirming with whoever's supplying the tables and chairs, especially once you know the room layout, whether there's a head table, and how the caterer wants their service area set up. Party Hire Near Me is a classifieds marketplace connecting hirers with furniture suppliers across Australia; we don't hold stock or set prices ourselves, so once your numbers are locked in, browse tables, chairs and furniture for hire to compare real suppliers, and check the bond and fees explainer so nothing about the final invoice is a surprise.
