It can be very disappointing to buy a new dining table for your dining room or dining space, then later realising when you set it all up that it doesn’t fit!

How to efficiently measure your dining table


Ok, so let’s cut to the chase.


The first thing we shall touch on in this dining table size guide is how to measure your dining table. This also includes how to ensure you have the right amount of space in your room to accommodate it without any hindrances.


So lets look at the image below:


Adeline 260cm black marble dining table

Adeline 260cm Black Marble Dining Table


Even though this table is 260 cm long, its pedestal base allows it to accommodate more people.


How? Well…


  • Because it takes up less foot area, there is more room to squeeze in seats around it.
  • The table’s pedestal base is centred in the middle. This eliminates any obstruction at the table’s corners, as in a more traditional form, allowing diners to sit closer together.
  • It has curved sides, so it can allow more table space – and hence more cutlery for additional diners – than a square-edged table.


Here are some close images:

So, what’s the point of all of this? What I’m attempting to demonstrate is that the design of the table, rather than its size, may influence the number of diners it can accommodate.


As a result, while measuring a table, keep in mind that certain long tables may accommodate more diners than others, even though they are the same length.


For example, check out the Mansfield 180cm Matt White Dining Table,


Mansfield White Matt 180cm Dining Table 1


This stylish table is 180cm long. However, due to its leg design, you would struggle to get diners on the edge unless they were children.


Once you have understood this concept you can measure your tables a bit more efficiently, getting the most out of your table for the space you have.


Dining Table dimensions:


Normally, the dimensions of our tables are provided in the description box, but if they aren’t, you can measure the table as follows:


Tables that are square or rectangular:


  • Length – For a square or rectangular table, measure in a straight line from one side to the other. This is the longest end and should be taken into account initially when trying to fit it into your dining area.


  • Width is calculated by adding the two shortest sides together. This is critical to understand if you have a small or narrow dining room.


  • The height of the table – Dining table heights is typically consistent. So this shouldn’t be too much of an issue; they should be approximately 74-77cm to the tabletop.


Like in this example:

mara 120cm rectangular glass dining table dimension
Mara 120cm rectangular glass dining table


The top of the table is 75cm while the underneath of it is 74cm.


and with the Opel extending which has a thicker surface:

The height to the top of the table is 74.5 cm whilst the underneath is only 72cm when extended.


Or like in this example:


Avignon 200 cm dining table dimensions
Avignon 200 cm dining table dimensions


It has a table thickness of 6cm!!!


Round and oval dining tables:


Length – Here the measurement is taken from the centre of the table down the middle. For example:

  • The above image illustrates the length is measure down the middle.


  • And the width is also measured across the widest part, which is usually at the centre of the table.


  • All other measurements are the same as other dining tables.


Octagonal Dining tables:

Each of these tables has its own uniqueness and advantages. 


For example, round dining tables are suitable for small rooms. The natural shape of a round table helps save space and bring people closer together.


A square table will be perfect in a small or square room and suitable for four people to dine on. 


Whilst all the shapes, rectangular and octagonal included, can fit well in a big room.


We will discuss all these shapes and sizes in this article and consider them before buying a dining table.


So how do you pick the right size dining table?

Measuring your dining table


Firstly, you need to measure the length and width of your dining area before deciding on the perfect table.


This will give you a good idea of the shape and size of the table that will fit flawlessly. 


If you have a squarish room, a round pedestal table is a good option because it takes less space and allows people to walk around.


Square and rectangular tables are good choices for spacious areas.


At a rectangular table, you should allow at least 3 inches of space per person, elbow to elbow, for optimal comfort; however, you can add more chairs if there are more people.


This gap between diners also allows for a bit more legroom.


Ideally, there should also be a space of 1.5 to 2 feet behind each chair for easy access to the table. 


This also allows you to walk behind people without disturbing them while they are seated at the table.

So, what is the standard size of a dining table?


This is the most asked question by people because they are not sure of the correct sizes of dining tables that will fit their space. The dimensions of the room should also be put into consideration.


The standard measurements for most dining tables are 36 to 40 inches in width and 29 to 31 inches in height. 


The length may also vary depending on the number of seats and people sitting at the table. 


Below is a summary;

 4-6       68-72″


6-8        72-80″

What are the different shapes of dining tables?


Dining tables can be designed in different shapes. 


There are: 


Rectangular dining tables

As mentioned earlier, the best shapes of dining tables that are suitable for small rooms are those in square and round shapes. 


These shapes can accommodate a bigger group of people without taking up a lot of floor space. 


A round table can extend to become an oval, while a square table can transform into a rectangular shape and accommodate more people.


When you have a bigger dining room and space is not a problem, you should consider rectangular or extending dining tables.


But to be fair, any dining table shape can fit in a large dining room.


Choose a shape according to the atmosphere you want to create in the room.
