Every office has one: the meeting table bought for eight that has never comfortably seated more than six. Nobody measured wrong, exactly — the brochure did say eight. What the brochure meant was eight people without elbows, laptops, papers or opinions. This is a short guide to the honest maths of a meeting table: how seats are really counted, what the room itself decides, and why the most expensive mistake is made before the table is even chosen.
The arithmetic nobody prints in brochures
The rule of the trade is simple: count the space per person, not the seats in the photo. Around sixty centimetres of table edge per person is the bare minimum — workable for a short briefing, uncomfortable for anything longer. Seventy to eighty centimetres is where meetings become civilised: room for a laptop, a notebook, a coffee, and the small territorial buffer that lets people think rather than defend their borders. Apply that maths to a table you are considering and the brochure's seat count quietly corrects itself — usually downwards by two.
The room votes before anyone sits down
A meeting table does not live alone. Chairs need to slide back and people need to walk behind them while others are seated — which, in practice, asks for roughly a metre between the table edge and the nearest wall or cabinet, and more on the side where people circulate. Measure the room first, subtract the circulation, and what remains is the honest maximum footprint of the table. Doing this in reverse — choosing the table, then discovering the room — is how boardrooms end up with chairs that touch the wall and guests who sidle to their seats like passengers on a budget airline.
Shape is strategy, not decoration
Rectangular tables are efficient and hierarchical: they seat the most people per metre and they create ends — which some organisations want (there is a chair for the person chairing) and others deliberately avoid. Round and elliptical tables equalise: everyone sees everyone, nobody owns an end, but each person consumes more space, so capacity drops for the same room. Boat-shaped tops improve sightlines down the length, which matters more than ever now that one seat is usually a camera. None of these is the correct answer; the correct answer is knowing which meetings the room actually hosts.
The camera is a guest with strong opinions
Hybrid meetings changed the geometry. A screen and camera at one end effectively consume a seat, and everyone needs a sightline to it that does not involve craning. Power and connectivity matter as much as centimetres: cables that arrive through the top, sockets that do not send guests under the table before a pitch. If your meetings are half video — and whose are not — plan the table around the screen end first and the seat count second. It is easier to add a chair than to move a wall-mounted screen.
What to settle before you order
Five things, in writing, before any meeting table is ordered: the room's dimensions with circulation subtracted; the real seat count at seventy centimetres per person, not sixty; the shape that matches how your meetings actually run; the route into the building — a three-metre top does not bend on a staircase, and some tables arrive in sections precisely for this reason; and the finish, approved on a physical sample rather than a screen. At La Mercanti we attach the manufacturers' declared dimensions and seat counts to every quotation — the numbers come from the people who built the table, and what they have not declared, we do not promise.
Quick answers
How much table space does each person need? Around sixty centimetres of edge as a minimum, seventy to eighty for comfortable working meetings. Divide the usable perimeter by that figure and you have the honest seat count — often two fewer than the brochure suggests.
How much clearance does a meeting room need around the table? Roughly a metre from table edge to walls or furniture for chairs to move, more on the circulation side. Measure the room, subtract the clearance, and let what remains decide the table — never the other way round.
Round or rectangular for a meeting room? Rectangular seats more people per metre and creates a head; round equalises the conversation but consumes more space per person. Choose by the meetings you actually run, not by the showroom photo.
Do large tables fit through normal doors? Often not in one piece — which is why serious manufacturers design large tops in sections with engineered joins. Ask how the table arrives and assembles before ordering, not on delivery day.
