Data on circulation around armchairs

Being able to move around armchairs in a living room is an important consideration.  Use this information in conjunction with layouts and furniture data.

Data on Living Room Layouts

We did a trial post called “Data on Living Room Armchairs and Sofas” some years ago (along with other “test posts”.  the idea being that if it achieved a certain number of hits then we would generate more articles of that ilk.

We recently have noticed that his post has met the target — so this is the “follow up”.  It is about layouts of living rooms.

Square Metre or Metre Squared:

Is four squared metres the same as four metres squared?

No, and the difference is vast, so care must be taken.

The best way is to remember that m² is always said aloud as “square metres” and never, ever as “metres square”. Some people prefer to write sq.m to help them remember.

Four metres square is sixteen square metres:

A square with sides equal to 4m — gives an area of 4m by 4m or 16m². (16 sqm). Think of this as saying four metres all squared — square the 4 and square the m — which is 4 x 4 x m x m = 16m².

Four square metres is two metres square:

A square with sides equal to 2m — gives an area of 2m by 2m or 4m² (4 sqm). Think of this as saying two metres all squared — square the 2 and square the m — which is 2 x 2 x m x m = 4m².

Two square metres:

A rectangle of sides 1m by 2m, produces an area of 2m²(2 sqm), and NOT two metres square.

Data on Living Room Armchairs and Sofas

Armchairs, couches, as well as three seater and two seater sofas are found in living rooms. Although furniture sizes can vary, there are basic constraints — doorways, room sizes and the human body being the main limiting considerations.
