When picking your sectional always remember the orientation.  for example with an L shape or chaise sectional are you going to choose the left chaise or the right chaise Style.  it’s simple but an easy mistake to make. it can be very talented and getting the furniture back to where you purchased it from and they may charge you a delivery fee again.

Tape it out

 One simple trick is using tape to measure out the dimensions of a sectional you are going to purchase and laying it out on the floor.  you can make sure you have enough room to maneuver through the room and that it’s not too big for the space.

This is my favorite tape for that won’t mess up the floor

Corner Seats  

emember sectionals are always going to have a corner seat.  if you’re not a fan of these and consider a curved sectional.  this area is usually best suited for children or if you don’t mind having your feet up while it is fully occupied.

Pairing With Other Decor

Styling a sectional is very similar to styling a couch but there are a few extra things to consider.


If you’re going to put a rug in the same room as a piece of furniture keep in mind that large rugs look better with larger pieces of furniture.  An area rug works with sectional couches. It’s a good idea to have the rug extend further than the sectional as this will make the room feel bigger. If you already have a small rug you can consider layering it with a larger rug.

One of my favorite trends is pairing a large jute rug with a neutral colored sectional.

Coffee Tables

This is one of my favorite coffee tables available on Amazon. It’s a great price for the rustic wood style.

A coffee table should typically stay within the space of the rug.  Just make sure you pick a coffee table that is large enough for the sectional.  If a coffee table is too small it can look awkward with a sofa sectional.

Accent Pillows

This handmade flower accent pillow that comes in a ton of colors is one of my favorites from Amazon

As with the rug and the coffee table, larger accent pillows look better with sectionals. They are a larger piece of furniture and go well wtih large decor.  make sure they pick up the extra bulk of the sectional.

All in all,  after reading this guide you should know everything you need to know about measuring picking and decorating a sectional. First, you need to learn what the common measurements used for sectionals are. Next, you need to decide which kind of sectional sofa shape is best for you.
