Measure Your Sofa or Sectional for Your Living Room

July 13, 2026

You did it. You finally got rid of that older-than-dirt couch and found the stylish sofa of your dreams at Bob’s Discount Furniture. 

But there’s still one more task left ahead: making sure that it fits in your home! Because after all, the last thing you want to do is find yourself trying to push your dream sofa through a too-small doorway.   

Check out our guide below on how to measure your sofa or sectional to fit your living room — so you can find a piece that fits your style, and your room, perfectly!

Tip#1:CheckTheLengthandTheDiagonal 

 

You probably already know how to measure the length of any sofa or sectional to make sure it fits in your room. But the key to getting it into your home and your room is to measure the side of any sofa or sectional piece on the diagonal from the bottom to top corner.

Doing this helps ensure that sectionals like the feature-packed Playday can fit through your doorway! 

 

Tip #2: Save Spacewitha Collapsible Back Panel 

 

Short on doorway space? Try a sofa with a handy collapsible back panel like one from our Aspen collection, which features a convenient, foldable piece to temporarily transform your sofa while you move it in!
