How to Measure Your Sectional
Get the exact measurements for the perfect rug fit
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
Measure the Short Side
Measure from the back cushions to the front edge of the chaise or seats.
Tip: Measure the deepest point
Add Walking Space
Add 24-36 inches to each exposed side for comfortable movement and chair clearance.
Tip: More space = more elegant look
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
Size Options for Your Sectional / L-Shaped
Choose based on your space and desired coverage.
Smallest size that works - front legs of sectional on rug
All front sections on rug, generous space for coffee table and movement
Entire sectional on rug for magazine-worthy look
