What is the typical size of a 12-seater dining table?

There is no single standard size, because tables vary by manufacturer and by the space available in your home or venue. For a rectangular table, the usual rule is to allow about 60 centimetres of width per person. Twelve people therefore need a table around 2.4 metres long at minimum, with 2.7 to 3 metres being more comfortable for a formal meal.

Round tables work differently because guests sit around the edge. A diameter of about 1.8 metres will fit twelve, but 2 metres gives more elbow room and makes passing food easier. If you are buying a table for everyday use as well as for your wedding, think about how often you entertain and whether you want to keep it smaller for quiet evenings.

Height is more consistent than length. Most dining tables sit at about 75 centimetres, which pairs with chairs that have a seat height of around 45 to 50 centimetres. If you are hiring, the venue will usually provide standard height tables, but check this if you have guests who need extra legroom or specific chair types.

When in doubt, sketch your table on paper to scale or lay out tape measures on the floor. This simple step often reveals space problems before you commit to a layout.
