A sofa cover only looks tailored if it is the right size. Measure once, check it against the table below, and you will get a smooth fit rather than a cover that bunches at the arms or slides off the seat.

How to measure
-
Width. Measure straight across the outside of both arms, at the widest point. This is the measurement that decides your size.
-
Depth. Measure from the front edge of the seat to the back of the backrest.
-
Height. Measure from the floor to the top of the backrest.
-
Count the seat cushions. A three-cushion sofa and a single-bench sofa of the same width can need different covers.
A note on units. Measure your furniture in inches, then use the table above to find the size to select. Our size selector shows centimetres, because that is how covers are manufactured, so the table gives you both.
Common measuring mistakes
- Measuring the seat instead of the outside of the arms. The arms are what the cover has to clear.
- Measuring an existing cover rather than the sofa. Old covers have stretched.
- Forgetting a chaise section. An L-shaped sofa needs a sectional cover, not a straight sofa cover.
One-piece or two-piece
A one-piece cover slips over the whole sofa and is quicker to fit. A two-piece cover has a separate seat section, holds its shape better on deep seats, and is easier to straighten after a busy weekend. If your sofa has loose, removable seat cushions, a two-piece cover usually looks neater.
If you fall between two sizes
Choose the larger size. Stretch fabric tightens to the frame, so a little extra material tucks away out of sight. A cover that is slightly too small will pull at the arms and never sit flat.

Look for |
Why it matters |
| Pets |
Dense woven jacquard |
A loose knit snags on claws; a tight weave does not. |
| Spills and children |
Waterproof backing |
The backing is what protects the upholstery, not the surface fabric. |
| A tailored look |
High-stretch spandex blend |
It pulls flat over the frame instead of draping loosely. |
| Everyday comfort |
Brushed or velvet finish |
Warmer to sit on and hides light creasing. |
Frequently asked questions
How do I measure a sofa with rolled arms?
Measure across the widest point of the arms, not the seat. Rolled arms add several inches on each side and are the most common reason a cover comes out too small.
Will a stretch cover fit a sofa with wooden arms?
Usually yes, but the fit is looser around exposed wood. Measure the full outside width including the wooden frame.
Can I put a sofa cover in the washing machine?
Yes. Wash cold, on a gentle cycle, and let it air dry. Avoid tumble drying, which shortens the life of the elastic.
