What height should a side table be?

Level with the arm of the chair or sofa it serves, or within 50 mm of it. Where there is no arm, go to seat height plus 50 to 80 mm.

What if my sofa has no arms?

Use the compressed seat height and add 50 to 80 mm. The table then sits just above your hand when your arm hangs, which is the natural place to put something down.

How close should it be?

Touching, or nearly. A side table that is 200 mm away from the arm is a table you have to reach for, and it collects the gap between it and the sofa.

Does the top size matter?

Less than the height, but a top under about 300 mm across holds a cup and nothing else. 400 mm takes a cup, a book and a lamp base.

What Height a Side Table Should Be

Match it to the arm or the seat, not to a catalogue number. The simple rule and the exceptions.

Side tables are the easiest piece of furniture to get right and people still buy them by looks and then live with a table that is 100 mm too low. One measurement decides it.

The rule

Match the arm. If the chair or sofa has an arm, the table top wants to be level with it, or within 50 mm either way.

The reason is mechanical. When you are sitting, your forearm rests at arm height. A surface at the same height means putting a cup down is a sideways movement with no lifting and no looking. A table 100 mm lower means lowering your shoulder; 100 mm higher and you knock the cup against the edge.

No arm?

Use the compressed seat height plus 50 to 80 mm.

Sit down, let your arm hang naturally, and notice where your hand falls. That is slightly above the seat. A table a little above seat height puts the surface exactly under your resting hand.

Measure the seat with someone sitting on it. A loose cushion loses 30 to 60 mm under load, and the specification sheet never accounts for that.

The numbers in practice

Seating	Reference height	Side table
Armchair with arms at 600 mm	Arm	550 to 650 mm
Sofa with arms at 550 mm	Arm	500 to 600 mm
Armless sofa, seat 420 mm compressed	Seat	470 to 500 mm
Dining chair used as occasional seating	Seat 450 mm	500 to 530 mm
Bed, mattress top 550 mm	Mattress	550 to 600 mm

The Drum Table is 480 mm high and 400 mm across, which puts it in the band for an armless sofa or a low-armed one, and makes it a bedside table for a mattress top around 500 mm. The Side Shelf at 620 mm is taller and suits an armchair with a high arm, or standing use.

Distance

Touching the seating, or within 50 mm. A side table is not a free-standing object in a room, it is an extension of the chair.

A gap between a side table and a sofa arm does two things, both bad. It puts the surface further from your hand than the height calculation assumed, and it creates a slot that collects remote controls, socks and dust.

Top size

Height decides whether it works. Size decides what it holds.

Under 300 mm across: a cup, or a phone. Pretty, limited.
350 to 450 mm: the useful range. A cup, a book, a small lamp.
Over 500 mm: starts to behave like a small coffee table, and in a tight room it blocks the route past the chair.

Round tops have an advantage next to seating: no corner at shin height. In a narrow space that is worth more than the extra surface a square top gives you.

Weight, which nobody considers

A light side table beside a sofa gets knocked, and a knocked table with a cup on it is a stain on a rug. Weight is stability. The Drum Table is a hollow concrete casting at 22 kg, which is more than most side tables and means it does not move when someone leans on it to stand up.

If a table is light, it needs a wide base. If it is heavy, think about the floor under it. Pressure is weight divided by contact area, and a heavy table on three small feet concentrates the load, which is covered in protecting floors under heavy furniture.

Two small beats one large

A pair of side tables at the ends of a sofa serves two seated people properly. One coffee table in front serves whoever is nearest it. In a small room the pair also keeps the floor clear, which matters more than surface area. The comparison is in matching coffee table height to a sofa.

Before you buy

Measure the arm, or the compressed seat plus 50 to 80 mm.
Check the route past the chair still works at the top size you want.
Stack books to the height and live with it for an evening.
Decide whether it needs to hold a lamp, because that changes the top size and the weight you want.

Reality check

Arm height, or seat plus 50 to 80 mm. Everything else is decoration.
Compressed seat, measured with a person on it.
Push it against the seating. A gap is a dust trap and a longer reach.
Under 300 mm across holds a cup and nothing else.
A light table beside a sofa will be knocked over eventually.
