Conference Room Table Size Guide and Seating Capacity Chart

Key takeaways

• Allow roughly 60 cm per person along the table edge for comfortable seating, and up to 75 cm for generous elbow room.
• Keep at least 90 cm of clear space between the table edge and the wall or furniture, and 120 cm if the area is a main walkway.
• Typical boardroom tables around 240 x 100 cm usually seat 8–10 people; for example, a large oak D-end boardroom model like the Office Hippo 240 cm D-end table fits this category.
• Room shape matters: long, narrow rooms suit rectangular or racetrack tables, while more square rooms can often take round or square tables more comfortably.
• When planning, measure your room first, subtract the recommended clearances, then choose a table that fits the remaining footprint.

Standard conference table sizes and dimensions

While manufacturers vary, most conference room tables follow broadly similar size patterns. Understanding these typical dimensions makes it much easier to estimate how many people a table will seat and whether it will fit your room.

Typical table lengths

Rectangular and racetrack (oval-ended) conference tables usually start around 150–160 cm in length and step up in 30–60 cm increments. Common lengths include:

• 150–180 cm – compact meeting tables for 4–6 people
• 200–220 cm – medium tables for 6–8 people
• 240–260 cm – larger boardroom tables for 8–10 people
• 300–320 cm – extended tables for 10–12 people
• 360–400 cm+ – large executive or training room tables, 12+ people

Many commercial tables are modular, so you might see sizes like 180 cm and 240 cm offered as part of the same range. For example, some freestanding boardroom tables are available in either 180 cm or 240 cm lengths with different leg styles, allowing you to scale up as your team grows.

Typical table widths

Width is just as important as length. A table that is too narrow can feel tight when laptops, notepads and refreshments are all in use, while an overly wide table can make conversation feel distant.

Standard widths for conference tables are:

• 80–90 cm – compact depth, best for small rooms or side meetings
• 100–110 cm – comfortable standard depth for most offices
• 120 cm+ – generous depth for larger rooms, bigger chairs and cabling

A popular size in many boardrooms is around 240 x 100 cm, providing enough depth for devices and documents without making it difficult to speak across the table.

Standard table height

Most conference tables are around 72–74 cm high. This matches typical office desk heights and works well with standard office chairs. Unless you are planning a sit–stand or bar-height meeting space, you can assume your table will sit in this height range.

As a rule of thumb, if a table dimension looks like a scaled-up office desk (around 72 cm high and 100 cm deep), it will usually work well with standard office chairs and existing office furniture.

How much space do you need around a conference table?

Once you have a sense of the table sizes you like, the next step is to check whether they will actually fit in the room. The most common mistake is to measure only the table footprint and forget about the space people need to pull out chairs and move around comfortably.

Recommended clearance around the table

Most offices work well with the following clearances:

• Minimum clearance: 90 cm from the table edge to any wall, cupboard or fixed furniture. This is enough for people to sit and move behind chairs carefully.
• Comfortable clearance: 100–120 cm provides easier movement and feels much less cramped.
• Primary walkways: 120–150 cm if people regularly walk behind chairs while meetings are in progress.

These measurements are taken from the table edge, not the table centre. If your room has doors, glass partitions or storage cabinets, remember to factor in the space needed to open doors fully.

Chair spacing and legroom

Chairs typically add 45–60 cm behind the table when in use. When someone is seated, their chair will extend into the area behind them, which is why the clearance from the wall or other furniture is so important.

For each person along the table edge, allow:

• 60 cm of table edge per person for typical office chairs
• 70–75 cm of table edge per person if you want more generous space or larger armchairs

Legroom is usually comfortable on tables with cantilevered or post legs set back from the ends, but centre pedestals or thick panel legs can sometimes get in the way. When reviewing specifications, look for leg positions and thickness to avoid seating someone directly in front of a bulky support.

Seating capacity by table shape

Different table shapes handle seating in slightly different ways. The same room might work with more people around a rectangular table than a round one, or vice versa, depending on how you arrange the chairs.

Rectangular tables

Rectangular tables are the most common in offices, especially for long, narrow rooms. They offer clear edges for placing chairs and make it easy to calculate seating capacity. As a general guideline:

• 150–160 x 80–90 cm – seats 4–6 (two on each long side, optional one at each end)
• 180 x 90–100 cm – seats 6 (three on each long side)
• 200–220 x 100 cm – seats 6–8
• 240 x 100–120 cm – seats 8–10
• 300 x 100–120 cm – seats 10–12
• 360 x 110–120 cm – seats 12–14

Longer tables often use multiple leg frames or arrowhead supports. Some designs with post legs at the corners, like a freestanding 240 cm rectangular meeting table, can feel more open at the ends and make it easier to seat people without knocking knees on supports.

Racetrack (oval / D-end) tables

Racetrack or D-end tables have rounded ends, which soften the look and make it easier to move around the corners. Seating capacity is similar to equivalent rectangular tables, with slightly more flexibility at the ends because there are no sharp corners.

As a guide:

• 200 x 100 cm racetrack – around 6–8 people
• 240 x 100 cm racetrack – around 8–10 people
• 300 x 110–120 cm racetrack – around 10–12 people

The curved ends can be ideal for chair positions that do not line up neatly with straight edges, giving you a bit of extra room if you occasionally need to squeeze in one more person.

Round tables

Round conference tables are excellent for small, collaborative spaces or informal meeting rooms. Their capacity depends mainly on diameter:

• 100–110 cm – 3–4 people
• 120 cm – 4 people comfortably, 5 at a squeeze
• 140–150 cm – 5–6 people
• 160–170 cm – 6–8 people

Round tables can feel more social because everyone is an equal distance from the centre, but they sometimes require more overall room space than a rectangular table seating the same number of people.

Square tables

Square conference tables are less common in traditional boardrooms but useful in small collaboration rooms or modular setups where multiple tables can be pushed together. As a rough guide:

• 80–90 cm square – 2–4 people
• 100–110 cm square – 4 people
• 120–130 cm square – 4–6 people
• 140–150 cm square – 6–8 people (using corners)

Because square tables can feel large in compact rooms, they are often better suited to more square-shaped spaces or combined with other tables to form larger layouts as needed.

How to measure your conference room for the right table size

Before you fall in love with a particular table, it pays to measure your room carefully. A few extra minutes with a tape measure can prevent years of frustration in a cramped meeting space.

Step-by-step measuring process

1. Measure the room length and width. Measure wall to wall, noting any alcoves or columns that might affect furniture placement.
2. Mark doors, radiators and built-in furniture. Record where doors open (and in which direction), as well as any radiators, cupboards or fixed credenzas.
3. Decide on your minimum clearance. For most offices, plan for at least 90–100 cm from table edge to wall, and 120 cm where people will walk frequently.
4. Subtract clearance from room size. From the room length, subtract clearance at both ends; repeat for the width. The remaining length and width is your maximum table footprint.
5. Check the route into the room. Make sure the table can be brought in, especially if it is a single large top. Check corridors, door widths and any tight corners.

Example: Seating 8 people in a typical UK meeting room

Imagine a meeting room that measures 4.5 m long by 3 m wide. You would like to seat 8 people comfortably around a table.

• Allow 100 cm clearance at the ends for easier movement: 4.5 m – 2 x 1.0 m = 2.5 m maximum table length.
• Allow 100 cm clearance at the sides: 3 m – 2 x 1.0 m = 1 m maximum table width.

This means that a table up to around 240–250 cm long and 100 cm wide would fit well. A 240 x 100 cm table suits 8–10 people, so in this room you would easily seat 8 with comfortable clearances. A sturdy rectangular 240 cm table with post legs or arrowhead legs would be a good example of this size in practice.

Example: Seating 10 people in a slightly larger room

Now consider a room that measures 5.5 m by 3.5 m, and you want to seat 10 people for board-style meetings.

• With 100 cm clearance at both ends: 5.5 m – 2 x 1.0 m = 3.5 m available table length.
• With 110 cm clearance at the sides: 3.5 m – 2 x 1.1 m = 1.3 m available table width.

In this space, you could comfortably use a 300 x 110–120 cm table for 10–12 people. If you prefer a little more open space, a 240 x 110 cm table would still seat 8–10 people but leave extra room around the edges for storage units or presentation equipment.

Example: Seating 12 people in a long, narrow room

For a longer, narrower room, say 7 m by 3 m, you might want to fit up to 12 people:

• With 100 cm clearance at each end: 7 m – 2 x 1.0 m = 5 m maximum table length.
• With 100 cm clearance at the sides: 3 m – 2 x 1.0 m = 1 m maximum table width.

This supports a table up to around 480 x 100 cm, which is more than enough for 12 people. Practically, many offices split this into two coordinated tables, such as two 240 x 100 cm tables placed end to end. This allows flexibility to split the room into two smaller meeting spaces if needed.

Layouts for narrow vs wide rooms

Room proportions influence not just table size but also table shape. Narrow rooms tend to suit certain layouts better than wide, almost square rooms.

Narrow conference rooms

In long, narrow rooms, rectangular or racetrack tables almost always work best. They follow the shape of the room and allow you to maximise seating without making movement difficult.

Tips for narrow rooms:

• Choose a table width of 90–100 cm rather than 120 cm to preserve side clearance.
• Keep storage units to one wall only, or use shallow credenzas to avoid reducing walkway space.
• Consider D-end or racetrack shapes to soften the look and make the ends easier to walk around.

Wide or square conference rooms

In wider or more square rooms, you have more freedom. Round or square tables can work beautifully, especially for collaborative teams, while shorter but deeper rectangular tables can be centred symmetrically in the space.

Tips for wide rooms:

• Try a round or square table if your typical group size is 4–6 and you want a more informal feel.
• Use the extra wall space for storage, screens or whiteboards without crowding the seating area.
• Consider a central power and data point beneath the table to keep cables neat across a wider surface.

Real-world size examples from popular tables

To make the dimensions more concrete, it can help to look at a few real-world examples from well-known ranges. These are typical of commercial office furniture and reflect the sizing principles discussed above.

Example: 240 x 100 cm D-end boardroom table

A large 240 x 100 x 73 cm D-end boardroom table in a modern oak finish is a classic boardroom choice. With its rounded ends and robust top, it will usually seat 8–10 people in comfort: three or four on each long side and one at each curved end when needed. A sturdy model such as the Office Hippo D-end meeting table is representative of this size and style.

Because the width is around 100 cm, it fits well in fairly standard meeting rooms while still providing enough depth for laptops, notepads and shared refreshments. The D-end shaping also makes it easier to move past people seated at the ends, compared with a square-cornered rectangular table of the same size.

Example: 180–240 cm rectangular table with post legs

Many Impulse-style freestanding boardroom tables come in both 180 cm and 240 cm lengths, with a consistent width of around 100 cm and straightforward post legs at the corners. A 180 cm version will typically seat 6 (three on each side), while the 240 cm version will seat 8–10, similar to the Impulse freestanding rectangular table with post legs.

Post legs leave the corners relatively open, which can help if you sometimes place chairs slightly around the corners for maximum capacity. For everyday use, the clear rectangular footprint makes them easy to plan for in CAD layouts or simple hand-drawn room plans.

Example: 240 cm rectangular table with arrowhead legs

Another variant uses arrowhead legs instead of post legs, as seen in models like the Impulse rectangular table with arrowhead legs. The footprint is still around 240 x 100 cm, but the leg design can change how close you comfortably seat someone at each end.

Arrowhead legs make a visual feature of the supports and can feel more solid under heavy use. When planning seating, you would normally avoid placing someone directly in front of the tip of the arrowhead, instead shifting end seats slightly to one side or using the long edges for most chairs.

Minimum space vs comfortable space

Another common set of questions revolves around minimum space. How little room can you get away with, and what is a more comfortable target?

Bare minimum guidelines

If you are working with a very tight meeting room, the following are absolute minimums rather than recommendations:

• Clearance from table edge to wall: 80–85 cm (chairs will be tight against the wall when pushed back)
• Table width: 80–90 cm in a narrow room
• Table edge allowance: 55–60 cm per person

At this level, people can still sit and stand, but movement will feel constrained and you will likely avoid seating someone directly behind a door or storage unit.

Comfortable, future-proof targets

For a space that feels pleasant and future-proof, aim for:

• Clearance around table: 100–120 cm on all sides where possible
• Table width: 100–110 cm
• Table edge allowance: 60–70 cm per person

This extra space makes it easier to accommodate different chair styles, occasional guests, or additional equipment such as microphones and AV controls.

Legroom, chair types and under-table space

Even when a table fits the room on paper, it can still feel awkward if the leg design clashes with your chair choice or if cables and floor boxes are in the way.

Common table leg designs and their impact

Most commercial conference tables use one of a few common support types:

• Post legs at the corners: Simple, open design; minimal interference with chairs except at the very corners.
• Panel legs: Solid panels at the ends or along the sides; can limit where feet and chair bases sit.
• Arrowhead legs: Angled supports that look striking but may constrain exactly where end chairs can go.
• Central pedestals or loop legs: Good under-table access but may reduce usable seating in the very centre if too bulky.

When planning your layout, it helps to sketch where each leg is positioned relative to the chairs, especially for longer tables with multiple supports. Try to avoid placing a chair directly in front of a thick leg or pedestal.

Chair types and their footprint

The type of chair you choose also matters:

• Standard office task chairs: Usually fine with 60 cm of table edge and 90–100 cm clearance to the wall.
• Executive high-back chairs: Often deeper and wider; plan for 70 cm of table edge and 110–120 cm clearance.
• Stacking meeting chairs: Usually more compact but may still need similar clearance once occupied.

If possible, measure your existing chairs and include their depth when fully occupied (not just when pushed under a desk) in your planning calculations.

Choosing the right table size for your office

To bring all of this together, start by identifying your typical meeting size and your most important room. If most of your meetings involve 6–8 people, you might prioritise a 200–240 cm table that fits comfortably with good clearance. If you regularly host larger board meetings of 10–12 people, look at longer rectangular or racetrack tables and ensure the room is long enough to support them with walkways.

From there, consider whether you need flexibility. Two smaller tables that can be joined end to end, such as matching 180 or 240 cm rectangular units, can be rearranged for workshops or training days. If your office design leans towards modern, you might pair a sleek laminate surface with simple post legs or arrowhead legs, making sure the support layout works with your planned seating.

If you are still unsure whether you need a full conference table or a more casual meeting setup, it may be helpful to explore the difference between formal boardroom furniture and other conference room tables for offices and meeting spaces, or to consider alternatives to traditional conference tables that may better suit flexible working styles.
