The first to measure is the height, and to do that, simply measure the couch from the underpart to the highest point of the seat’s backrest and measure the width from one arm to the other, left to right.

For the depth, you need to measure from the front to the back of the longest side of the sectional. 

How Much Space Do You Need Around a Sectional?

A sectional would offer more seating and would make any space look stunning, but the only downside to this seating option is that it needs space.

Leave at least 24 inches or 61 centimeters of space around the seat unless pushed on the wall on one side. This space is required so people can have room to walk around. 

Measure your wall space, especially if the couch will be pushed against the wall. The size to consider is the width of the sofa
