Since a sectional sofa is the most oversized furniture piece in your living room, it’s recommended to measure before buying one. This way, your sectional will fit in your space. 

How to measure a sectional couch

Knowing how to measure a sectional couch contributes to a more well-thought-out space. There are three things you need to consider when measuring sectional sofa dimensions:

  • Width
  • Length
  • Height

Measure your space

Ensure you know the precise measurement of your living room so you can gauge the correct sectional sofa size to buy. Grab a tape measure and determine the entrance openings where the sofa will be carried through. Measure doorways, hallways, or foyers and the overall room size

Next is to measure the area where you want to put your sofa. Tape the area and get the estimated measurements. This will help you find the exact sofa size and picture the orientation.

How to measure a sectional sofa’s width

The sofa’s width starts from one end to the other end of the sofa’s back. The total width of the couch is relatively longer than its length and is between 94 and 168 inches. 

How to measure a sectional sofa’s length

The sofa’s length is the extended seating perpendicular to the width. Some sectional couches have chaises on both sides. If this is the case, measure the longest side. The average sofa length is between 94 and 156 inches.

How to measure the sectional sofa with wedge

A sectional sofa with a wedge refers to the couch’s rounded back and differs from a chaise. Use a flexible tape measure to get precise measurements of the curves. Determine the center point of the curved sofa by measuring from one end to the other, then dividing that number by two.

Measure the distance from the center point to the end of the sofa on one side. Measure the backrest height from the floor to the highest point of the curve. Then, measure the sofa's depth from the front to the back of the seat. Finally, measure the length of any straight sections on the couch, if applicable.
