### Consider before measuring a Sectional sofa

Sectional sofas come in different sizes. But you must make your thoughts simple to get started to actually get the dimensions of a sectional couch. Go to your living room and check the sides of the sectional sofa. Check every side, commonly the long side is rectangular and the shorter sides compared to the rectangular side, it should be like a parallelogram. The curved sectional sofa’s sides look like a parallelogram, so it might get confusing but do not confuse your imagination. Or else it won’t work.

Imagining as rectangle and parallelogram is done. Now here comes the measuring part with a measurement tape. Now what you should do is divide the whole sofa size into 4 sections. Think of two lines bisecting each other at a 90-degree angle. It’s just like the cartesian graph. In the X to X’ it is the height of the sectional couch. And the Y to Y’ line is the width of the sectional couch. It is just applicable for the parallelogram sides of the sofa that you imagined earlier.

You got the height and the width of the sofa. But remember that the width doesn’t include chaise sectional. For the chaise sectional I am explaining the length of the sofa. Now go to the rectangular side of the sofa and just measure one side to another side by side to know the overall length of the sofa. It seems like a whole lot of work but I will make it simple.

And for the chaise sectional, Just add the measurement of the chaise side by side with the width that you got earlier. That’s it.

### Measuring Summary:

Let me explain the whole thing in a more simple way.** First of all for the width and the height you just need to think of the sides as a parallelogram if it is not totally square or rectangular.** Then just simple geometry **measures the height of the parallelogram and the base to get the width.**

For the chaise section just add the measure of the chaise sectional base to the width to get the total. Now for the other sides of the sofa, it should be in a rectangular shape. Just measure the two sides to get the overall length of the sofa easily.

I should mention that there are different sizes and shapes of sofas available. Like 3-seater, 5-seater, l-shaped sectional, u-shaped sectional, modular sectionals, reclining sectional, chaise sofa, chaise lounge, accent chairs, leather sofa, regular sofa, small sectional, large sectional, /chaise sectional, curved sectional, corner sofa, curved sectionals, reclining sectionals, traditional sofa, etc and many more. They all can be measured the same way. So do not worry.

**How to measure the depth of the sofa?**

An actual seating area has a depth of a certain number of inches. Therefore, it includes the size of the seating cushions, the back cushions, and the frame behind the cushions. In order to know how deep the seating area will be, you need to measure the depth.

Firstly, **measure the sofa’s length; then add a couple of inches for the sofa’s frame, and you’ll have the sofa’s depth.**

### Diagonal depth:

From the highest point of the back frame (without pillows) to the front of the arm, place a straight edge to determine the diagonal depth of a sofa. Afterward, measure the straight edge bisecting the bottom rear corner of the sofa. The last measurement is the diagonal depth.

**How to measure a sectional sofa with a wedge?**

There are three steps to measure a sectional sofa with a wedge. Measurement with a wedge involves specific techniques, unlike traditional sectionals without rounded corners. Don’t worry, it’s relatively simple.

**Second Step:** Measure the dimensions

On the cross-section of the tape measures, place a piece of tape and mark the inner edges. The same should be done at both ends and the center back of the sectional. As a result of marking several points where the tapes intersect, a rectangle will be formed with the dimensions you need to house the curved couch.

**Last step:** Draw a sketch of the sofa with the measurements
