How to Measure Your Sectional

Get the exact measurements for the perfect rug fit

1

Measure the Long Side

Measure from the outside edge of one arm to the opposite corner (the full L span).

Tip: Include armrests in your measurement

2

Measure the Short Side

Measure from the back cushions to the front edge of the chaise or seats.

Tip: Measure the deepest point

3

Add Walking Space

Add 24-36 inches to each exposed side for comfortable movement and chair clearance.

Tip: More space = more elegant look

4

Match to Standard Size

Round up to the nearest standard rug size. It's better to go bigger than smaller.

Tip: When in doubt, size up

The Front-Legs Rule

Front legs of all sectional pieces should sit on the rug, with the coffee table centered.

Common Mistake: Using an 8×10

Using an 8x10 that barely covers the main section, making the L-shape look awkward

Placement Guidelines

Position your rug correctly for the best look.

Do This

  • • All front legs of the sectional should be on the rug
  • • Coffee table should sit entirely on the rug
  • • Leave 12-24" of rug visible beyond the sectional on open sides

Avoid This

  • • Don't let the rug float in front of the sectional with no furniture on it
  • • Don't use a rug where only the main section is on it and the chaise floats
  • • Don't push all furniture to the walls with the rug isolated in the center

Pro Tips

  • 2Coffee table should sit entirely on the rug
  • 3A 9×12 is the minimum - 10×14 for larger sectionals

Frequently Asked Questions

A 9×12 rug is the recommended size for most sectionals, providing proper coverage for the L-shape with front legs on and room for a coffee table. An 8×10 is the minimum, while a 10×14 offers magazine-worthy full coverage.
Center the rug on the main seating area, ensuring the front of both sections has legs on the rug. The chaise portion can extend slightly past the rug edge if needed. The coffee table should be fully on the rug with at least 12 inches of rug visible around it.
It's acceptable for the chaise to extend past the rug edge, especially with an 8×10. The key is that the main seating sections have front legs on the rug and the overall look feels intentional. Sizing up to a 9×12 usually eliminates this issue.
For extra-large sectionals over 130 inches, consider a 10×14 rug or layering two rugs. Some retailers offer 11×14 or custom sizes. Ensure the coffee table area is always fully covered regardless of sectional size.
