Side Tables: The Right Height for Each Piece of Furniture

Next to the sofa, the armrest decides

The reference value is not the seat height but the top edge of the armrest. The tabletop should lie at this height, plus or minus two to three centimetres (0.8–1.2 in).

The reason lies in the movement of the arm. Anyone resting on the armrest and putting down a glass moves the hand out sideways, not downwards. If the top lies lower, the shoulder has to follow, and the table visually disappears behind the edge of the sofa. If it lies considerably higher, it cuts into the sofa's silhouette and looks as if bolted on.

Common armrests are between 55 and 65 centimetres (21.7–25.6 in) above the floor. These are therefore also the standard dimensions for the table next to it. A height of 60 centimetres (23.6 in) hits the middle of this range and therefore suits most upholstered furniture.

With sofas without armrests or with very flat, wide arms, this reference value is missing. There, the rule is seat height plus fifteen to twenty centimetres (5.9–7.9 in), which with a seat height of 43 centimetres (16.9 in) comes to around 60 (23.6 in).

On distance: the table stands at the armrest, with zero to five centimetres (0–2.0 in) of space. Every additional centimetre is distance the arm has to bridge while seated. From about twenty centimetres (7.9 in) away, the side table becomes a piece you can look at but not use.

Sofas with splayed feet or a continuous plinth are an exception. If the base projects sideways beyond the armrest, the table cannot be pushed up flush. Then a narrow foot or a top that reaches over the plinth helps.

Next to the armchair, other rules apply

An armchair usually stands freely in the room, often at an angle. The table next to it is therefore accessible from two or three sides, and a round or square top works better than a long rectangular one that always points in one direction.

When seated, the arm reaches about 55 to 65 centimetres (21.7–25.6 in) to the side without the upper body shifting. The top must lie within this radius, otherwise you have to get up for every cup.

With deep lounge chairs with low armrests, the calculation shifts downwards. There a height of 40 to 45 centimetres (15.7–17.7 in) is more suitable, while the same piece would be clearly too low next to a classic wingback chair with a high back.

Stools are often underestimated in this role. By design they are at seat height, that is usually between 40 and 45 centimetres (15.7–17.7 in), have a solid top and can take weight accordingly. Next to a deep armchair they replace the side table; when guests come, they become a seat again. The prerequisite is a flat, unupholstered top.

If two armchairs stand side by side, one table between them is enough, provided both people seated can reach it within the radius mentioned. If the seats are more than about 130 centimetres (51.2 in) apart, this calculation no longer works.

Next to the bed, the top of the mattress counts

The measurement is taken from the floor to the top of the mattress, without topper and without duvet. Common beds are at 50 to 60 centimetres (19.7–23.6 in), box-spring beds at 60 to 70 (23.6–27.6 in).

The tabletop belongs at this height up to a maximum of ten centimetres (3.9 in) above it. The reason is obvious, yet it is regularly ignored: lying down, the hand gropes sideways, not downwards. A bedside table that is too low will sooner or later cost a glass of water.

This results in two separate groups. A table of around 50 centimetres (19.7 in) in height is designed for normal bed frames; next to a box-spring bed with a mattress top at 65 centimetres (25.6 in) it would be too low. There the suitable height is more like 65 to 70 centimetres (25.6–27.6 in). Anyone who does not know the height of the mattress top should measure it before buying, because depending on the topper it varies by several centimetres.

On surface area: next to the bed, book, glasses, glass and phone collect, usually all at once. Below 30 by 30 centimetres (11.8 by 11.8 in) that gets tight. If a lamp stands on it, its base takes up additional space.

In the hallway, seat height becomes standing height

Here there is no seat to take as a reference. Anyone putting down keys, post and glasses while standing reaches comfortably between 75 and 90 centimetres (29.5–35.4 in). A side table of 60 centimetres (23.6 in) is too low for this and serves at most as a surface for setting down a bag.

At 70 centimetres (27.6 in) the borderline range begins: high enough to be usable while standing, but only if the top is large enough. A footprint of 25 by 25 centimetres (9.8 by 9.8 in) holds a bowl and nothing else.

In the hallway, depth matters more than height. A passage width of 80 centimetres (31.5 in) should remain free, better 90 (35.4 in). In a hallway 120 centimetres (47.2 in) wide, that means: at most 30 to 40 centimetres (11.8–15.7 in) of depth, otherwise you have to turn sideways to get past every time.

If the hallway is narrower than 120 centimetres (47.2 in), there is no more room for a free-standing piece. Then a wall-mounted console or a shelf takes over the task, because nothing stands in the way under the top.

Footprint, centre of gravity and the question of when something tips over

Narrow tall tables look light and are light. A table 25 centimetres (9.8 in) in diameter at a height of 60 centimetres (23.6 in) is almost two and a half times as tall as it is wide. From a ratio of about two to one, a table becomes noticeably more prone to tipping. With a footprint of 25 by 25 centimetres (9.8 by 9.8 in) at a height of 70 centimetres (27.6 in), the ratio becomes even less favourable.

Whether that is a problem depends on two things: where the weight sits and what the table stands on. If a slender frame carries a heavy stone or solid wood top, the centre of gravity is at the top, and the total weight helps little. Conversely, a heavy foot stabilises even a tall table. On a hard floor this hardly matters. On a deep-pile rug, narrow feet sink in unevenly, and the table stands permanently slightly askew.

Felt pads help against slipping, not against tipping. They usually sit under the foot or under the base ring and compensate for small unevenness. They change nothing about the proportions.

What stands on the top shifts the calculation further. A vase twenty centimetres (7.9 in) tall on a top of 25 centimetres (9.8 in) raises the centre of gravity once again. This is where things get uncomfortable: in a household with small children or a large dog, with such proportions the question is not whether the table will fall over at some point, but when.

The alternative is a wide, low table. If the top measures 60 by 60 centimetres (23.6 by 23.6 in) at a height of 45 centimetres (17.7 in), the table is wider than it is tall and can hardly be knocked over. The price for this is floor space: such a top takes up more than five times the footprint of a narrow model.

How much surface is actually needed

A glass has a diameter of around 7 centimetres (2.8 in), a cup with saucer about 15 (5.9 in), a hardback book measures 15 by 22 centimetres (5.9 by 8.7 in). A round top of 25 centimetres (9.8 in) holds two of these items, and that is it.

From about 40 by 40 centimetres (15.7 by 15.7 in), a side table becomes a real surface for putting things down. Below that it is a pedestal for one or two objects. That is a legitimate decision, as long as it is made consciously and does not come as a disappointment later.

With round tops, the diameter is additionally deceptive. A circle has a good fifth less area than a square with the same side length, and the edges are hard to use because objects overhang there. Anyone wavering between round and square who needs surface space is better off with the square version.
