how to measure a sofa



When it comes to buying a sofa, the first thing you need to do is measure your space. This is especially true if you're buying an L-shaped or sectional sofa, as these items can take up a lot of room. While you may think that your purchase will be limited by what's available at the store, there are actually many online retailers that offer custom sizes. Most importantly, make sure that the sofa doesn't crowd any other pieces in the room especially a coffee table!

Measure the length.

To measure the length of your sofa, begin at one end of the piece and use a tape measure to find the total length. This is not just an arbitrary measurement: it's important because it will help you determine how much fabric you need once you've decided on a pattern.

To measure the seat width, place yourself in front of the sofa seat while facing forward and hold one end of your measuring tape at waist height against its front edge (the edge closest to you). Slowly walk toward its back until you reach a point where your arm is fully extended; record this number as your seat width.

Next, move onto measuring its backrest but don't get too excited! Since most sofas are covered with cushions that extend beyond their backsides by several inches, we recommend using an actual ruler instead of relying solely on your handy dandy measuring tape for this one (you'll thank us later). Starting from one side of each cushion's rear edge (again making sure that both ends stay straight), use something rigid like an old credit card or gift card as leverage against said edge until it meets up with where another cushion begins; then mark where these two pieces intersect using pencil or pen before moving onto doing so again on another side of each cushion until all four have been measured out separately--and yes! You should repeat this process three more times in order because there are usually five cushions per couch set-up (three along both sides plus two smaller ones underneath).

Measure the width.

Measure the width in inches of the room you plan to put your sofa in. Measure from one end of the wall to its opposite end, as well as from corner to corner. If there isn't a clear 'end' or 'corner' on either side of your room, measure from any convenient spot in each direction.

Measure the length and depth (height) of your furniture piece(s). Take into account whether or not it has arms that stick out, like sofas do; if so, measure those too!

If you're purchasing new furniture for a doorway or stairway, be sure to find out what its dimensions are before going out shopping. Most desks and dressers come with standard dimensions but when it comes to furniture like beds or desks whose size varies greatly depending on what they're made for (such as children's rooms), you'll want to double-check whether yours will fit through whatever doorways/stairways they need access to before buying them.

Measure the height.

You can measure the height of your sofa by following these steps:

  • Measure the length and width of your sofa.

  • Measure the back of your sofa, keeping in mind that it is not just one flat piece but two separate pieces joined together at a seam, so make sure you add both measurements together when calculating how big to cut the foam cushioning for this part of the seat cushion. If there’s an armrest attached to one side of your sofa, measure that separately as well.

  • Now it’s time to measure how tall each part is: The seat should be measured from floor level up until it hits its highest point (often just below where someone would normally rest their arms), while any armrests should be measured from floor level up until they hit their highest point (which will usually be somewhere between elbow and shoulder height).

Take other measurements into consideration.

Before you measure the couch, consider these other dimensions.

  • The depth of the sofa is the distance from front to back, at its widest point (usually around seat cushion level).

  • The height of a sofa is measured from the floor to the top of its backrest or armrests. This will be especially important if you plan on placing your furniture against a wall or other obstacle that borders your living space.

  • Seat depth refers to how far into a chair or couch you can sit before reaching armrests and this may vary depending on whether it's wide enough for your body type and how large/small it is overall. If you're tall, go with something with deep seats; if short, opt for something more shallow so that even though it doesn't give much leg room underneath yourself when sitting upright in place, there remains plenty when reclined backward against cushions instead (which are usually shorter but still soft). If unsure about which way would work best or if having both kinds sounds appealing consider buying an adjustable chair where users can choose between multiple positions based on preference alone! That way no matter what kind goes better with certain occasions then others then there'll always be something suitable nearby whenever needed most."

no matter what the style, the size of your living room determines the size of your sofa.

Regardless of the style you choose, or even if you don't choose a style at all, the size of your sofa should be proportional to the size of your living room. The size of a sofa will be determined by how much space is available in your home and how many people will be sitting on it. If you have an open concept living area with high ceilings and wide-open spaces, then one larger sofa would work well for the space because it's not cluttering up the room as much as multiple small ones would do. If there are more than three walls and/or low ceilings (think: apartment), then multiple smaller pieces may look better in this type of setting where they can fill up some visual space without dominating every inch against large unused areas like those found in homes with higher ceilings or fewer walls around them.


Measurements are an important part of buying furniture, and a sofa is no exception. Measure your space before purchasing one and make sure it fits the space you want to put it in.
