Seats at the rectangular table
Most of the tables are typically rectangular or round shapes. By rectangular table, you may sit people by the longer sides, set as a length in the How many tables calculator. Most rectangular tables are not wide, so that a maximum of one person can sit at the head. If you want to sit people there, the calculator will provide you with the proper value at the bottom of the tool.
For each person to sit comfortably, the calculator assumes 60 cm of space, but if you think it should be changed for specific reasons, you can also change it.
Round table seats
For the calculator purposes, there is a second type to choose at the first step so that you will be able to calculate how many people may sit on your round table as well.

8 seater dining table example
Imagine an example of 8 seater dining table at your home. Let's compare rectangle and round table options.
Rectangular table
For a rectangular table with a default of 60 cm per person:
Number of people = (Length / 60cm) × 2
The formula contains multiplier by two because the calculator assumes that people may sit on both sides of the table.
To calculate the table's length, we modify the formula.
Length = (Number of people / 2) × 60 cm = (8 / 2) × 60 cm = 240 cm
You may also try using the calculator for six people to get the length and sit two remaining people at the head of the table.
Length = (6 / 2 × 60cm) = 180 cm
You may sit 8 people by 180 cm table if the table's head will be used to seat two people.
Round table
Using the same data in How many tables calculator to find the size of rounded table:
Number of people = 2π × radius / 70 cm
Modify the formula above to get radius value
Radius = Number of people × 70 cm / 2π = 8 × 70 cm / (2 × 3.14) = approx. 90 cm
The above results mean that if you want an eightseater dining table, you need either a rectangular table 240 cm long or 180 cm long with seats at the head of the rectangular table or a round table with a radius of around 90 cm.
