Coffee Table Dimensions: How Many cm, and How Far from the Sofa?

Short answer: the top of a coffee table should sit level with the seat height of your sofa, or 5-10 cm below it. For most sofas, whose seat height is 40-45 cm, that means a table 30-40 cm high. On width, the rule is this: the table should be about two thirds as long as the sofa it stands in front of. A table of 100-160 cm suits a 240 cm three-seater. Leave 40-45 cm of space between sofa and table.

Coffee table dimensions: why 30-40 cm high?

Table height is not an aesthetic preference, it is an ergonomic requirement. Reaching for a glass from where you sit, your arm needs to come down from the elbow at a slight angle. If the table is higher than the seat, you have to raise your shoulder; if it is much lower, you have to lean forward.

The formula is simple: measure the seat height of your sofa and aim for the same figure, or 5-10 cm less. On modern deep sofas the seat drops to 40-42 cm; low tables of 30-35 cm look right with those. On classic, upright sets the seat is around 45 cm and a 40 cm table works better.

The Arinna coffee table set on the site covers that range with three separate pieces:

↔ Scroll the table sideways to see all of it.

The 30 / 35 / 45 cm trio here is no accident. The first two are at coffee table height; the third is close to sofa armrest height, so it does the job of a side table.

How many centimetres should a coffee table be? Width against the sofa

The length of the table should be in proportion to the sofa opposite it. Too small a table gets lost in the middle of the seating group; too large a one closes off the walkway.

On depth, the 60-80 cm range works. A table 80 cm deep gives a surface you can reach comfortably from both sides; a slimmer 60 cm top keeps the walkway open in narrow rooms. If you do not know your sofa dimensions, you can look them up in the table in our article on sofa set dimensions and living room layout.

How much space should there be between sofa and table?

The right gap is 40-45 cm. That measurement solves two things at once: you can reach your glass from where you sit without leaning forward, and you can get up and past without knocking your leg on the table.

It is easy to see what happens at the extremes:

• 30 cm and under: knees touch the table and stretching out your legs becomes impossible. The problem is worse with deep sofas.
• 60 cm and over: the table is no longer part of the seating group; you have to stand up to put your glass down.

On corner sofas, take the measurement from the longest wing; the distance in front of the corner module is always tighter. Placing the table at the centre of gravity of the seating area, rather than dead centre in the corner, gives a more balanced result.

If you need to position the table together with the sofa and the TV unit, the spacing diagrams in our article on how to plan a living room layout put all the pieces in place at once.

What are nesting tables, and what is a side table for?

Nesting tables are a group, usually of three, made in different sizes so they slide under one another. When not in use they nest together and take up no more room than a single table; when guests arrive they separate and spread around the room. The name comes from that nesting logic, and they are one of the most practical space-savers in a narrow living room.

The large and small tops in the Arinna set work exactly on that principle: normally they nest, and when needed they separate and go to either end of the sofa. The Ürgüp coffee table, meanwhile, is a set of three separate bodies: a coffee table, a large side table and a small side table.

A service table, or side table, does a different job from a coffee table. At around 45 cm high it stands level with the sofa armrest; it is a surface you can reach without getting up, for a coffee cup, a book, the remote and your phone. Placed beside an armchair, it turns that corner into a genuine reading spot.

A practical rule: a coffee table is shared, a side table is personal. Allow one side table for every separate seating spot in the room.

Choosing material and shape

• Round or oval top: having no corners, it causes no knocks in tight walkways and is safer in homes with small children. It works well with corner sofas.
• Rectangular top: gives the most usable surface in the classic arrangement of a three-seater and a two-seater; it is also the best form for a nesting set that splits in two.
• Square top: pulls the balance together in symmetrical layouts with two facing sofas or a corner set.
• Surface: a matt wooden top does not show fingerprints and hides scratches; gloss lacquer and glass tops are more striking but need daily cleaning. Stone and ceramic tops are unaffected by hot cups.

You can compare the models and their dimensions in the coffee table category, and if you are planning the whole seating group, have a look at the living room section.
