Well, it seems the provided context consists of a YouTube footer and a Wayfair navigation menu, which are about as helpful for measuring a sofa as a spoon in a sword fight. So, let's cast that aside and get down to business with some good old-fashioned knowledge.
Getting your sofa's measurements for a slipcover is like taking its vitals before surgery, or perhaps more accurately, before it gets a fabulous new outfit. You want a snug fit, not a saggy, baggy mess that looks like a ghost is perpetually halfway through sitting down.
First, arm yourself with a flexible measuring tape. A rigid metal one will just get into an argument with your sofa's curves. Start with the main event: the full width. Measure from the outermost point of one armrest, all the way across the front, to the outermost point of the other armrest. This is the big number, the one that determines if the slipcover will even get past the sofa's shoulders.
Next, you'll want to measure the height. Go from the floor, up and over the highest point on the sofa's back, and down to the floor again on the other side. Some guides just ask for the height from the floor to the top of the back, so check the specific slipcover's sizing chart to see which dimension they're after. While you're at it, measure the depth from the very front of the sofa to the very back.
Don't forget the seating area! Measure the width between the arms and the depth of the seat cushions from front to back. If your cushions are separate, you might want to measure one of them individually (length, width, and height) in case you're getting a multi-piece set.
Finally, write these numbers down. Don't trust your memory. Treat these measurements like a secret code, because they are the key to transforming your couch from drab to fab without it looking like it’s wearing a potato sack.
