Seating assumes a standard chair width of about 45 cm. Allow more room if you want serving space between guests.

How we count
Each guest needs roughly 45–50 cm of table edge, which is why the closed figures are shown as a range: the lower number is comfortable spacing, the higher one is chairs tucked closer together.
Extension plates are 50 cm wide and sit at both ends or across the middle, so each plate adds 2 seats, one on either side. The plate width is added to the table length, and the depth stays as it was.
A round table becomes an oval once plates are added, which is why the width grows while the depth stays at the original diameter.
