What size conference room table fits into this office space? Our conference room calculator can help.

conference room calculator

How do you choose the appropriate size conference table for your conference room?  Here is a conference room size calculator to help. 

A general rule of thumb is to have at least 42” between the edge of the table and the wall or other stationary piece, such as a credenza.  This allows just enough room to walk behind a person seated at the table. 

In order to determine the maximum size of conference table that will in your conference room, you will need to measure the length and width of the conference room.  Then, subtract 7’ from both measurements, and what you have left is how big your conference table can be. For example, if you have a room that is 19’ long x 12’ wide, then the maximum size of table that will comfortably fit in your conference room is 12’ long x 5’ wide.  However, keep in mind that unless you are buying a custom conference table, there are a limited number of standard sizes offered by most conference table manufacturers.


19′ x 12′ Room Size – 7′ =  12′ x 5′ maximum size of conference room table 

Example 2:

21′ x 10′ Room Size – 7′ =  14′ x 3′ maximum size of conference rom table

Conference Table Dimensions

If you have the flexibility to choose the size of your conference room, then the most important thing to consider when choosing your conference table size is how many people you need to seat around the table. Generally speaking, you should allow for at least 24″ to 30” per chair.  Another common rule is that the number of chairs that will fit around the table is the same as the length of the table, meaning 12 average size chairs will comfortably fit around a 12’ table (as pictured above).  If you select a large-scale office chairs for your conference table, this rule may not apply.

Executive Conference Room Chairs

We have tried lots of conference room chairs.  Our favorite executive conference room chairs are these chairs by Wyatt Seating.  We like the high back and there is plenty of seat cushion.  The arms are sleek and it is available in grey and black.  This is a statement conference room.  It screams bring your A game, we are getting down to business!  You can order the executive conference room chairs online here via our affiliate link.  We earn a small commission.  If you are in Kansas or Missouri, you can order directly from us.  We also think this chair makes an excellent executive task chair.  For a task chair, the arms are switched out for adjustable arms.   Also, if you prefer the mid back vs. the high back, this chair has that option too.  Coming in more than $500, it isn’t a budget chair.  As such, we put it in the executive category.  🙂

Connectrac Flex Power

One of the challenges of a conference room or meeting room is how to handle power.  Connectrac Flex Power is a solution for flat power under carpet tiles.  Many clients want power in their conference room tables.  Since conference tables are typically in the middle of the room, how do you power that table?   You can do a core drill in the floor.  Depending on the flooring, this isn’t always easy.  If you are in a multiple story building, you need to enter the floor below you and disrupt them to do the drill.  Or, you can come off the wall and go over the carpet. If you do that, how do you not create a trip hazard or eye sore?   This connectrac flex power solution of coming off the wall, but under the carpet tile solves the problem.  No trip hazard or eye sore!  Reach out to us for a quote!

    12′ Conference Table in 18′ x 10′ Room

    In this install of a 12′ racetrack conference table, we have the minimum amount of space for chair movement of 3′ on each side. The conference chairs are Steelcase Amia. For more about this install, we walk thru the various office desks, cubicles, and office dividers chosen.

    12 Seater Conference Table Size

    By contrast to the table above, we have a larger conference room where they wanted a 12 seater conference table.  Here we installed a 16′ foot x 5′ rectangle conference table.  We have 5′ of clearance all around the table.  With that 5′ wide table, we could easily add 2 conference chairs on each end of the table to sit 16 or the client can keep it the way they have it as a 12 seater conference table.  Some 16′ tables are only 4′ wide.  If that is the case, it will be tighter to get 2 people on each end.  For us to quote a 16′ conference table for you, please e-mail us at

    Conference Room Size for 10

    Although we have encouraged you to have 36″ to 42″ of chair movement space, this client needed a conference room size for 10. The room size was only 15′ x 7’7″. You can see how tight the space is in this room. We had to customize the table in depth and length. There are (2) mobile tables at 50″ x 28″ in this space. The chair was very important. When the conference room is not in use, the arms needed to fit under the table. The chairs also needed to be mobile. The client selected the Herman Miller capers from our used office inventory.

    Modular Conference Table

    We believe office furniture should be flexible for your needs.  With this in mind a modular conference table could be what you want.  For even more flexibility, you might want to think about flip top tables or nesting tables.  

    What is flip top table?

    A flip top table or nesting table does as it is described.  The table top flips so that the tables can store easily.  You might say they nest together.  Basically, the tables are spooning.  We love them!  And, if you want your own nesting tables, please reach out.  We would love to quote you a modular conference table.
