Sofas are the heart and soul of the living room. If you ask them, most people will say that they consider color, fabric, style, texture, and quality of materials while buying their sofa. What people often forget is the size!

The dimensions of your sofa are very important because they can make or break how your room looks. For example, if you have a long and narrow living room, putting multiple sofas, including 3-seaters and armchairs, may not be a great idea. Sectionals might be a good option for this scenario.

Dimensions Of Sectional Sofa

The sectional sofas are customizable. So you cannot say its exact dimensions. But there are some general measurements which you need to keep in mind before buying a sectional sofa.

#1. Overall Length

The overall length is the combination of either right-hand or left-hand loveseat and corner chair. It is usually between eight to thirteen feet (94 to 168 inches)long.

#2. Overall Width

The measurement of the back sofa gives you the total width of the sofa. It is usually longer compared to the overall length of the sectional sofa and usually falls between ninety-four to one sixty-eight inches wide.

#3. Other Measurements

You need to consider the interior side of the sectional sofa if you are thinking of pairing the sofa with a center table or coffee table or a centerpiece like an ottoman.
