Standard Sectional Couch Size

A standard sectional couch has an overall length of between 94 inches and 156 inches. The length of a sofa is defined as the combined length of both loveseats plus the entire stretch of a chaise lounge.

 Its overall width, which would be its entire back, ranges from 94 inches to 168 inches. The depth of a sofa is the measurement of how deep the couch would sink if you sit on it. For a standard sofa, this is usually between 32 inches to 40 inches.

How to Choose the Right Sectional Couch for your Room

Sectional couches don’t come cheap. Buying a great quality sectional couch will cost you a substantial amount. It is why matching the couch size to your space is vital.

Generally, furniture would appear smaller in showrooms because of the grand nature of the place. So it is important to have an idea of what an ideal piece of furniture for your space would measure.

To make the best choice think about the following things.

Room Measurement and Shape of The Room

When measuring a room, consider the square footage. Work with the length and width for practicality. You can draw out the room to scale and play around with different couches to see how the proportionalities relate.

Measuring can also be a great way to see how different style sectional couches would fit in with the room’s geometry. The shape of your room will help you decide on the sectional couch’s proper situation and the configuration to go for, whether RAF,  LAT, or armless.

The measurement of a room will help you decide on the actual size of the sectional couch. Rember small rooms work well with small sectionals, and big rooms work well with big sectionals.

When measuring, you can also approximate measurement for your couch and use it as a guideline to get a couch of about that size. Unless you are getting a customized couch, it is rare to find one with the exact measurement you have in mind.

Free Movement

A great sectional couch for your space does not constrain movement. When selecting the appropriate size, remember to ensure that there is enough room for you to move around freely when the sofa is fitted.

You could factor this in and leave appropriate maneuver space around the sectional couch if you made a scale drawing.

Ceiling Height

Usually, sectional couches sizes are based purely on the ground space of your room. Ceiling height consideration is merely for esthetic purposes. When working on areas with high ceilings, you can make the space more charming by going for a low-backed and wide sectional couch with an extensive length.

It makes the space more visually appealing, making it appear more extensive.
