What Size Sofa Cover Do I Need? Size Guide by Seater

What Size Sofa Cover Do I Need? Size Guide by Seater

Which size sofa cover do you need? Match your sofa's width, measured arm to arm, to one size: 1-Seater fits 90 to 130 cm, 2-Seater 135 to 175 cm, 3-Seater 180 to 220 cm, 4-Seater 225 to 300 cm. Between two sizes? Size up, and the two-way stretch does the rest.

Your size in 10 seconds

One number decides your size: the width across the back, from the outer edge of one arm to the other. Find that number in the chart, and you have your cover.

Not sure of your number? Measure in 60 seconds

You need one measurement to choose your size, and four to be sure of a clean fit:

  1. Width, arm to arm, the number that sets your size.
  2. Depth, front of the seat cushion to the back.
  3. Height, floor to the top of the backrest.
  4. Arm shape, rolled, square or low.

The full method, with the small mistakes worth avoiding, is in our how to measure a sofa guide. For ranges mapped to every sofa type, see the Covaba size guide.

Between two sizes? Size up.

Stretch fabric takes up slack far better than it stretches past its limit: a slightly larger cover settles in, a slightly smaller one strains. If your arms are especially wide or rounded, add 5 to 8 cm (2 to 3 in) to your width before choosing.

Frequently asked questions

What size sofa cover do I need for a 3-seater?

A 3-Seater cover fits roughly 180 to 220 cm (71 to 87 in) measured arm to arm. If your sofa is wider than 220 cm, choose the 4-Seater size.

What if my width falls between two sizes?

Size up. A slightly larger stretch cover settles onto the frame cleanly, while a smaller one strains at the seams.

Do these covers fit L-shape and U-shape sofas?

Yes, but corner and U-shape sofas are covered section by section: measure each run and order one cover per section. Our shape guide explains the count.

How do I measure the width correctly?

Measure straight across the back, from the outer edge of one arm to the outer edge of the other, including the arms, with cushions in their normal position.

Can I machine wash the cover?

Yes. Wash cool at 30°C on a gentle cycle, reshape while damp, and dry on low or flat. Avoid hot washes and high heat.
