What size wall clock for a living room?

A wall clock is one of the few decorative objects that also has a job, and size decides whether it does that job. Too small and it looks lost and cannot be read from the sofa; too large and it crowds everything else on the wall. Here is a practical way to choose the diameter, the height and the position, with numbers you can check with a tape measure.

Start with reading distance

The first question is how far away you will be when you look at it. A useful rule of thumb is about 10 cm of clock diameter for every metre of viewing distance. In a living room where the sofa is 3 to 4 metres from the wall, that points to a clock of 30 to 40 cm as the minimum for easy reading. Anything smaller than 25 cm belongs in a kitchen, a study or a hallway, where you pass within a metre or two of it.

Legibility is not only diameter. Clear hands that contrast with the background matter more than numerals: a clock with bold hands and simple hour markers reads faster at a distance than one with twelve ornate numbers and thin hands.

Then measure the wall

The second question is how much wall the clock has to hold. Designers use the same proportion for clocks as for art and mirrors: the piece should span roughly two-thirds to three-quarters of the width of the furniture beneath it, or, on a bare wall, leave at least 20 to 30 cm of clear space on every side.

• Above a 90 to 120 cm console or sideboard: 50 to 70 cm.
• Above a 180 to 220 cm sofa: a single clock of 60 to 90 cm, or a smaller clock as part of a group.
• On a narrow wall between two doors or windows: measure the gap and take off 40 cm.
• Above a fireplace: no wider than the mantel shelf, and ideally around two-thirds of it.

What counts as a large wall clock?

Most shops describe 25 to 35 cm as standard, 40 to 55 cm as large and 60 cm and above as oversized. An oversized clock is really a piece of wall art that tells the time. Open designs carry that size more easily than solid ones: a skeleton or starburst clock, where you see the wall through the metalwork, feels lighter than a solid face of the same diameter. Our 69 cm starburst metal wall clock is a good example: at 69 cm it fills the space above a sideboard, but the slim spokes keep it from looking heavy, and they throw their own shadows on a plain wall.

How high to hang it

Hang a clock so that its centre sits at about eye level, 150 to 160 cm from the floor, when it is on an open wall. Above furniture, leave 15 to 25 cm between the top of the furniture and the bottom of the clock so the two read as one arrangement. Above a fireplace you will end up higher than eye level; that is fine for a large clock, which is meant to be read from across the room.

Check the weight and the fixing before you drill. Most decorative clocks hang from a single keyhole or hook on the back; use a wall plug and screw suited to your wall rather than a nail, particularly for metal clocks over 50 cm.

One big clock or part of a gallery wall?

A clock of 60 cm or more wants a wall to itself. Give it clear space and keep other pieces on adjacent walls, for instance a large canvas on the wall opposite. A clock of 30 to 40 cm works well as the anchor of a gallery wall: hang it slightly off-centre and build outwards with photo frames, keeping 5 to 8 cm between pieces. A round clock is also a simple way to break up a wall of rectangles.

Sound, movement and batteries

Size is what you see; the movement is what you live with. In a living room or bedroom, look for a silent or sweep movement if ticking bothers you, and expect to change a single AA battery about once a year. Buy the battery with the clock, as most are shipped without one.

A quick checklist

• Measure the viewing distance: about 10 cm of diameter per metre.
• Measure the furniture below: aim for two-thirds to three-quarters of its width.
• Centre at 150 to 160 cm, or 15 to 25 cm above furniture.
• Choose open metalwork for anything over 60 cm.
• Use a proper wall fixing, not a nail.
