Walkway, as a planning guide
Most armchairs are 25.5 to 33.5 in wide and 29.5 to 35.5 in deep. For comfort, look at the seat: a lounge armchair usually has a seat height of 14 to 17.7 in and a seat depth of 19.7 to 21.7 in. In the room, a good planning guide is about 35.5 in of walkway around the chair and 16 to 18 in between the chair and a coffee table.
An armchair is bigger than it looks in a photograph. The footprint of a deep lounge chair is closer to that of a small table than a dining chair, and the measurements that decide comfort, seat height and seat depth, are rarely the first ones listed. This guide explains every dimension on an armchair, what the typical ranges are, which numbers matter for your body and which for your room, and how much space to leave around the chair. Every figure is in inches, with the full measurements of our own armchairs, Kent and Einar.
What is the standard size of an armchair?
Most armchairs are 25.5 to 33.5 in wide, 29.5 to 35.5 in deep and 27.5 to 39.5 in tall, depending on the style.
Compact armchairs for small rooms start around 23.5 in wide; generously padded club chairs can pass 35.5 in. Height varies most, from low lounge chairs to high-backed wing chairs.
The chart below gives the full measurements of our two armchairs, taken from their technical drawings.

What seat height should an armchair have?
Lounge armchairs usually have a seat height of 14 to 17.7 in, lower than a dining chair's 17.7 to 18.9 in.
The lower the seat, the more you lean back and the more relaxed the chair feels. The trade-off is that a low seat is harder to rise from.
Seat height is measured from the floor to the top of the seat cushion at the front edge. Kent and Einar sit at 15 in, a true lounge height. For a chair at a table, see our dining chair height guide instead.

How deep should an armchair seat be?
A seat depth of 19.7 to 21.7 in suits most adults in a lounge armchair: deep enough to lean back, not so deep that your feet leave the floor.
Seat depth is measured from the front edge of the seat to the back cushion. Taller people are happy with more depth; shorter people may want a cushion behind their back in a very deep chair.
Kent and Einar have a seat depth of 20.9 in, with full-height back cushions. Our guide to what makes an armchair comfortable explains how seat height and depth work together.
How high are the arms of an armchair?
The arms of a lounge armchair usually sit 17.7 to 25.5 in from the floor: low arms keep a chair open and light, high arms wrap around you.
Try the arms with your forearms resting on them. They should carry the weight of your arms without lifting your shoulders. Arm height also decides which side tables work beside the chair.
The arms of Kent and Einar are 19.3 in from the floor, 4.3 in above the seat cushion, a low line that keeps the chairs open. A side table of 17.7 to 21.7 in sits comfortably next to them.

As a planning guide, leave about 35.5 in of walkway in front of or beside the chair, and 16 to 18 in between the chair and a coffee table.
The coffee table distance is close enough to put down a cup without leaning forward. The walkway lets people pass without climbing over feet.
With a deep lounge chair, also check the depth against the wall behind it: Kent and Einar need 31.9 to 32.3 in from the wall to the front edge. Our guide to where to put an armchair covers layouts with a sofa.
How do you measure your room for an armchair?
Measure the width and depth of the floor you have in mind, subtract the walkway, and mark the chair's footprint on the floor with tape before you buy.
Measure door openings and stairs too. Our armchairs are delivered fully assembled, so the chair has to pass through the narrowest doorway on its way in, turned on its side if needed.

Plan for a footprint of 25.5 to 33.5 in wide and 29.5 to 35.5 in deep, a seat 14 to 17.7 in high and 19.7 to 21.7 in deep, and, as a rule of thumb, 35.5 in of walkway around it. Kent measures 26.4 x 32.3 in and Einar 28 x 31.9 in. Both are made in our own factory in Malmö, Sweden, delivered fully assembled and covered by a 10-year warranty.
