The right dining table should provide enough seating without restricting movement around the room. A table that is too small can look out of proportion and become impractical when guests visit. A table that is too large can make chairs difficult to use and interrupt the route through the room.
This guide explains how to measure your dining area, calculate the correct table size and understand the relationship between table dimensions and seating capacity.
Measure the Room First
Start with the room, not the table. Measure the full length and width of the dining area, including any obstructions such as radiators, cabinets, doors and structural features.
Mark out the proposed table dimensions on the floor using masking tape or a measuring tape placed flat. This lets you check how much space remains around the table before committing to a size.
How Much Space Do You Need Around a Dining Table?
Allow at least 90 cm between the edge of the table and a wall, cabinet or nearby furniture. This is the minimum clearance for a person to sit comfortably and push a chair back without hitting an obstruction.
For a busy walkway or a route between the kitchen and dining area, 110 to 120 cm is a more comfortable minimum.
If the table is positioned against a wall on one side, reduce that side's clearance to around 45 to 60 cm, as that edge will not be used for seating or movement.
How Many People Should the Table Seat?
Decide on the number of people the table needs to accommodate on a regular basis and how many it needs to seat on occasion. These numbers are not always the same.
A table used daily by three people may only need to seat six when guests visit. In that case, a table sized for everyday use is often more practical than one sized for the largest gathering you might ever host.
How Much Space Does Each Person Need?
Each seated person needs approximately 60 cm of table width. This provides room for a place setting without crowding neighbouring seats.
A round table seating four people needs a minimum diameter of around 100 cm. A table seating six people in a round format needs approximately 140 to 150 cm in diameter.
Rectangular and oval tables follow a similar calculation along their length. A 140 cm rectangular table can typically seat four people. A 180 cm table can seat six. A 220 cm table can seat eight, depending on the chair width and base position.
Table Sizes and Seating Capacity
The following figures are general starting points. Actual capacity depends on the shape of the table, the width of the chairs and the position of the base.
For rectangular and oval tables: 140 cm seats four, 160 to 180 cm seats six, 200 to 220 cm seats six to eight, 240 to 280 cm seats eight to ten.
For round and square tables: 100 cm seats four, 120 to 130 cm seats four to six, 140 to 160 cm seats six.
Table Depth: 90 cm or 100 cm?
Oval, rectangular and ellipse tables from Kavestone are available in two depths: 90 cm and 100 cm.
A 90 cm depth is a practical choice in a narrower room, where clearance behind chairs is limited, or where you do not regularly place large serving dishes in the centre of the table.
A 100 cm depth gives more space between opposite place settings and works better in rooms where the additional width is not a constraint.
Mark both depths on the floor before deciding. An extra 10 cm can make a meaningful difference in a room with limited clearance.
Which Table Shape Suits Your Room?
The shape of the table affects how it fits the room and how many people it can seat.
Rectangular Tables
Rectangular tables work well in longer rooms. Their straight sides make it simple to align the table with walls, islands and cabinets. They are also the most straightforward shape for calculating seating capacity.
Oval Tables
An oval table provides similar seating to a rectangular table of the same length but removes the four corners. This can improve movement around the table and reduce the sense of enclosure when chairs are occupied.
Round Tables
Round tables work particularly well in square rooms. They have no corners, which can improve movement in a smaller space. Seating capacity is limited by diameter, so check the full dimensions before assuming a round table will seat the required number.
Square Tables
Square tables create an equal arrangement on all four sides. They are best suited to a square dining area where sufficient clearance can be maintained around the full perimeter.
Ellipse Tables
An ellipse has a long, curved form with more tapered ends than a standard oval. It provides a softer alternative to a rectangular top while keeping a clear sense of length in a longer room.
Account for Doors and Routes Through the Room
Check that doors opening into the dining area will clear the table and chairs when fully open. Also consider the route between the kitchen and the dining table, particularly if food is carried regularly between the two.
A clearance of 90 cm may be sufficient for movement when the table is empty. When chairs are occupied, the effective clearance can reduce to 60 cm or less. Wider routes reduce the likelihood of accidental contact with seated guests.
Mark Out the Table Before Ordering
Use masking tape to mark the full footprint of the proposed table on the floor, including the chairs placed in their occupied positions. Walk through the room to check every route and confirm that doors clear the arrangement.
This step takes a few minutes and regularly prevents the error of ordering a table that does not fit the space as expected.
Kavestone Table Dimensions
Kavestone's oval, rectangular and ellipse tables are available in lengths from 140 cm to 280 cm, with a choice of 90 cm or 100 cm depth. Round and square tables are available from 100 cm to 160 cm.
If your room requires a size outside these options, contact Kavestone to discuss custom dimensions. Larger bespoke tables are available following consultation.
