Sofa Cover Measurement Worksheet

Use this worksheet before buying a sofa cover. Write down the sofa shape, outside width, seat depth, back height, arms, chaise length and the number of loose cushions. Then use the Fit Lab or product page to choose the cover format.

Measurement Your sofa Why it matters
Outside width First path for one-, two-, three-, four-seater or sectional planning.
Seat width Used for seat pieces and sofa protectors.
Seat depth Shows whether a piece can cover and tuck without exposing the front edge.
Back height Needed for backrest pieces and full covers.
Arm width and height Needed when arms are wide, rounded, sloped or visibly worn.
Chaise length Needed for L-shaped, sectional and oversized sofas.
Loose seat cushion count Helps decide how many seat pieces are needed.
Loose back cushion count Helps decide whether backrest pieces are needed.

Photo checklist

Front photo

Shows seat count, arm shape, back height and whether cushions are loose or fixed.

Top-down photo

Shows chaise direction, seat depth, corner modules and which zones need coverage.

Side photo

Shows arm height, sofa depth and whether a cover has enough drop to sit cleanly.

How to use the numbers

For a fixed-cushion straight sofa, outside width and overall shape normally decide the first stretch or throw-cover path. For a loose-cushion sofa, measure every seat and back cushion separately because individual pieces may work better. For an L-shaped or sectional sofa, measure the main span, the return, the chaise depth and each loose cushion or module.

Do not buy by seat count alone. A compact three-seater and a deep family three-seater can need different cover sizes. A cover that is slightly generous may tuck or drape in a piece-based format, but a stretch cover should stay inside the intended product range.

Quantity planning section

Use this section when the product is sold as separate pieces. Write down the number of zones before adding products to cart. A sofa may need one cover for each seat cushion, one for each back cushion and separate pieces for arms or chaise sections. If you only want to protect the high-use seats, your quantity will be smaller than a full sofa plan.

Zone How many on your sofa? Likely cover path
Single seats Often starts with 90x90cm or the product's single-seat option.
Wide two-seat bench zones Often starts with a wider 110x160cm style option where available.
Long three-seat or chaise zones Often starts with 110x240cm or a larger throw-style cover where available.
Backrest cushions Measure each loose back. Do not assume it is the same as the seat.
Armrests Only cover arms that are used, worn, visible or needed for a complete look.

Fit notes by household

Pets

Measure the favourite seat first. Dogs often mark the front edge and cats often use a backrest or corner. The best cover plan follows the pet's actual habit, not only the sofa size.

Children

Measure the snack and drink zone carefully. A washable protector on the main sitting area can be more useful than covering sections that are rarely touched.

Rentals

Choose removable coverage and record the sofa condition before installing the cover. Keep the measurements and photos until the first fit check is complete.

Final pre-order check

Before ordering, compare the worksheet with the product page. Confirm the selected variant, colour, piece count, dimensions and care notes. If the sofa has unusual arms, a chaise, recliner action, loose backs or a very deep seat, open the Fit Lab again and use the closest sofa shape rather than guessing from the product image.

Keep the worksheet until the cover has been installed and sat on. Some covers look correct immediately after smoothing but shift after real use. If the cover moves too much, the notes on shape, depth and cushion layout will help identify whether the issue is size, format or installation.

Sofa-shape examples

A straight fixed-cushion sofa is usually measured as one connected shape. Record the outside width, depth, back height and arms, then compare stretch, fitted or throw-style options. A straight sofa with loose cushions should be measured both as a whole sofa and as separate cushions because the moving parts may need their own covers.

A chaise lounge needs two sets of numbers: the main sofa span and the chaise length. The chaise side also matters because left and right layouts affect how the cover is placed. A modular sectional should be drawn as blocks. Write one measurement on each block so you can decide whether the whole setup needs a relaxed cover, separate seat pieces or a mixed plan.

An armchair or recliner is not just a small sofa. Check the arms, back height and moving parts. A recliner may not suit a tight fitted cover if the mechanism needs space. Outdoor seating should be measured by cushion and frame separately because cushion thickness, moisture exposure and storage habits affect the best cover choice.

When to ask for help before buying

Ask for fit guidance before checkout if the sofa has a curved back, very wide arms, a recliner mechanism, several loose back pillows, an unusually deep seat, a corner wedge, a chaise return or a leather surface that may cause movement. A short message with three photos and the measurements from this worksheet is more useful than saying only that the sofa is a two-seater or three-seater.

The best help request includes the product URL, selected variant, sofa width, seat depth, back height, chaise length where relevant, and the number of seat and back cushions. That information lets Sofa Decor point you toward the right product family faster: stretch cover, throw cover, sofa protector, seat pieces, backrest pieces or sectional cover planning.

Measurement worksheet FAQs

What is the first sofa measurement to take?

Start with outside width from one outer arm to the other outer arm. Then record seat depth, back height, arms and cushion layout.

Do I need to measure loose cushions separately?

Yes. Loose seat and back cushions can move independently, so measure each cushion as its own cover zone.

Should I measure a chaise separately?

Yes. Measure chaise length and usable width separately from the main sofa span because it usually needs a different cover plan.
