How to Measure a Sofa for a Stretch Cover: Fit Worksheet

Before choosing a stretch sofa cover, record your sofa’s measurements in centimetres and match them to the exact cover’s measuring diagram. The number of seats is only a label: it does not confirm that the arms, back or cushions will fit. Use the worksheet below to separate what you have measured from what a listing actually confirms.

This is a buying checklist, not a universal size chart or a fit guarantee. It is designed for checking a whole-sofa stretch cover; a loose throw or a separate cushion case needs its own product-specific measurements.

The three checks that matter before you order

1. Same measurement: are your tape measure and the product diagram using the same start point, end point and route?
2. Compatible shape: does the guide address your sofa’s arms, back, cushions and any separate sections?
3. Confirmed contents: does the selected item include all the pieces you expect?

If any answer is unknown, keep it as a question. Do not turn a missing measurement into a tick simply because the cover stretches.

Your sofa record: copy this into a note

Have the selected product page open and measure the sofa as it normally sits, with its usual seat and back cushions in position. Put decorative scatter cushions aside. Record the date and take a front and side photo for your own reference.

These are descriptive measurements of your furniture, not instructions to substitute for a seller’s diagram. Add every measurement requested by that diagram, even if you have already recorded a similar one.

• Sofa description: ___; straight sofa, chaise, corner, modular or reclining: ___.
• Outside width: ___ cm, straight across between the outermost edges of the arms. Include any flare or roll.
• Overall depth: ___ cm, from the frontmost to the rearmost point, viewed from the side.
• Overall height: ___ cm, from the floor to the highest point of the back.
• Inside seat width: ___ cm, between the arms.
• Seat depth: ___ cm, from the front of the sitting surface to the front of the back cushion or backrest.
• Back height above the seat: ___ cm, from the top of the seat cushion to the highest point of the back. Note whether you measured vertically or along the surface. Keep this separate from floor-to-top height.
• Arms: square, rolled, flared or other: ___; dimensions requested by the product guide: ___.
• Separate parts: seat cushions ___; back cushions ___; chaise or modular sections ___.
• Extra measurements from the product diagram: ___.

Take each reading again using the same endpoints. If the results differ, check the tape position rather than averaging measurements taken in different ways. Label a straight-line measurement separately from one that follows the sofa’s surface.

Turn the listing into a match-or-question record

Make one record per candidate cover. Copy the dimension wording exactly, then add your own matching measurement. A number without clear endpoints is not yet a completed fit check.

• Product name, link and selected size: ___.
• Listing’s dimension or range, copied exactly: ___.
• Diagram’s start point, end point and tape route: ___.
• My reading using those same points: ___ cm.
• Result: within the stated range / outside the range / cannot compare yet.
• Shape compatibility confirmed by: ___; still unknown: ___.
• Included pieces confirmed by: ___; quantity needed: ___.

Repeat the dimension lines for every measurement the product requires. A width match cannot answer a missing question about a deep seat or unusually wide arms. If a measurement sits at a boundary or between options, ask for that product’s guidance rather than automatically sizing up.

A GoodGoodHome example: what the specification does and does not tell you

The Anyseat 4 Seater Sofa Cover Grey specification lists polyester, “XLarge(235-300cm)” and a package containing one sofa cover. These details were checked on 31 October 2026; recheck the current listing before buying.

Record 235–300 cm as the listed range, not as an independently confirmed fit for your sofa. The written specification alone does not define that measurement’s endpoints or give separate depth, back-height and arm limits. Check any current sizing diagram and ask for clarification where those details remain unclear. Do not assume the range means inside seat width, straight outside width or a measurement following the sofa’s contours.

Likewise, “one sofa cover” is not a promise of separate covers for every cushion or modular section. This is a useful example of why a product’s seat label and a single range cannot complete the whole checklist.

When a straight-sofa checklist is not enough

For a chaise or corner sofa, sketch the layout from above and name each section. Mark the front of the sofa so that “left” and “right” have a clear reference. Confirm the seller’s orientation convention, which sections are supported and which pieces are included; do not infer the required number of covers from an L-shaped photograph.

For a recliner or sofa bed, obtain confirmation that the selected cover is designed for that furniture and its moving parts. A size match alone does not establish compatibility. Do not force a standard cover around controls or mechanisms.

A short question to send before buying

I am considering [product link and size]. My sofa is [shape], with [arm type and cushion layout]. The listing gives [exact range]. Could you confirm the measurement endpoints and tape route, the required depth/back/arm limits, and which pieces are included? My labelled measurements are [figures in cm]. I can provide a front photo, side photo and layout sketch if needed.

Keep the reply with your measurement note and a copy of the item description. The ACCC’s buying-online guidance recommends retaining item descriptions, receipts and other records. Check the current returns terms too; do not assume an unsuitable fit will qualify for a change-of-mind return.

Final check: fit is only one part of the decision

A completed measurement record does not establish waterproofing, claw resistance, exact colour matching or washing conditions. Check those separately on the selected product, and follow the supplied care label. A cover is not a structural repair for damaged furniture.
