New covers can be cut to your pieces, one measurement line at a time.* Also asked as: Is it possible to alter the size of the covers?; Covers for my existing sofa > **The quick answer:** Yes, custom size modular sofa covers can be made for another brand's sofa, in any size, as long as you give the exact dimensions of each piece in the personalization box. An 80 x 39 1/2 x 7 in (203 x 100 x 18 cm) base is a real example. Custom covers take slightly longer to produce, and a photo of the sofa may be requested. ![Five box cushions fanned on oak boards in ivory, olive, burgundy, aqua and emerald velvet, each with contrast piping](https://cushionguide.com/media/cushion-covers/five-velvet-cushions-fanned-oak-floor-piping-1600.webp "Fanned out on oak, five piped cushions read like a color card for pairing body fabric with piping.") ## Key facts - Covers can be made in any size. - Custom cover sizes go in the personalization box. - Each piece needs its own exact dimensions. - A real example: an 80 x 39 1/2 x 7 in (203 x 100 x 18 cm) base with 39 1/2 x 39 1/2 x 10 1/2 in (100 x 100 x 27 cm) L-shaped cushions. - Custom covers take slightly longer to produce than standard ones. - The workshop may ask for a photo of the sofa to get the fit right. ## Measuring pieces you didn't design 1. **Number every piece**: Base, backs, corner, L-shaped cushions. Covers are cut piece by piece, so each one gets its own line. 2. **Write length x width x thickness**: One line per piece, for example 80 x 39 1/2 x 7 in (203 x 100 x 18 cm) for a base. 3. **Photograph the sofa**: One clear photo of the whole sofa, plus any odd-shaped piece, helps the workshop get the fit right. 4. **Put it all in personalization**: Every size goes in the personalization box; send the photo when it's asked for. ## A cover you didn't design is a cover you have to read The cover is cut to what you write, so send the true size of each piece rather than a padded guess: an 80 x 39 1/2 x 7 in (203 x 100 x 18 cm) base, then 39 1/2 x 39 1/2 x 10 1/2 in (100 x 100 x 27 cm) L-shaped cushions, and so on. The photo carries what numbers can't, like the turn of an L-shaped cushion or where a back meets a seat. Teddy-style modular pieces with exact measurements are accepted. Not every sofa is, though: one five-piece set with a storage ottoman was declined, so send photos and sizes before ordering if yours is unusual. Custom covers take slightly longer than standard ones.

How many pieces does your sofa come apart into, my friends? > **Tailor's margin:** Custom sofa covers are cut to what you write, so give one line per piece, like an 80 x 39 1/2 x 7 in base. > Replacement covers for another brand's modular sofa can be sewn in any size, as long as every piece arrives with its exact length, width and thickness. > > — Élodie Marchand ## Buyer questions **A common question:** Can you sew replacement covers in custom sizes for a sofa I bought elsewhere? **The workshop's answer:** Yes, covers can be made in any size. Give the dimensions of each part in the personalization box, for example an 80 x 39 1/2 x 7 in (203 x 100 x 18 cm) base and 39¼ x 39¼ x 10¾ in (100 x 100 x 27 cm) L-shaped cushions. Custom covers take slightly longer, and a photo of the sofa may be requested. **A common question:** Will you cover another brand's teddy-style modular sofa? **The workshop's answer:** Yes, as long as you give the exact size of each piece. **A common question:** Can you make teddy sofa covers for mattresses I already own, plus backrests? **The workshop's answer:** Yes. Put your mattress sizes in the order notes and empty covers are sewn to fit, with matching L-shaped backrests, as covers only or filled for an extra charge. ## Questions buyers ask next ### Can the covers close with elastic instead of a zipper? Mattress covers are zipper-only. Elastic sofa covers can be quoted, but with a warning that they fit poorly on soft, rounded cushions; an open-bottom skirted cover is another option for daybeds. ### How much longer do custom covers take? Slightly longer than standard covers. No fixed number of days was given, so if you have a deadline, mention it when you send your sizes. ### Can I order zippered throw pillow covers to go with them? Yes. Use the zippered cover listing, put the sizes in the Exact Size field, note they are pillow covers with your color and piping codes, then message the shop. ## Related at the atelier - [Will your replacement covers fit a teddy floor sofa from another brand?](https://cushionguide.com/answers/teddy-sofa-covers-fit-other-brands/): Teddy sofa replacement covers usually fit another brand's sofa when the dimensions match: seats of 78 x 39 x 6.5 in (200 x 100 x 17 cm) and L-shaped backrests of 39 x 39 x 15 in (100 x 100 x 39 cm)… - [Can you make slipcovers for the sofa I already own?](https://cushionguide.com/answers/slipcovers-for-existing-sofa/): No: the workshop doesn't make fitted slipcovers for a whole conventional sofa (arms, back and skirt) or for an unrelated multi-piece set, such as a five-piece sofa with a storage ottoman. - [What's in the covers-only set, and what size are the covers?](https://cushionguide.com/answers/floor-sofa-covers-only-set-dimensions/): A covers-only set dresses one single floor sofa with four zippered covers: two seat covers of 78 x 39 x 6.5 in (200 x 100 x 17 cm) and two L-shaped backrest covers of 39 x 39 x 15 in (100 x 100 x 39… - [Slipcover, new covers or new cushions: pick the right fix](https://cushionguide.com/guides/slipcover-or-new-cushion-covers/): Whether a couch needs a slipcover or new cushion covers depends on what is worn. - [Matching fabric from a previous order: dye lots, add-ons and discontinued colors](https://cushionguide.com/guides/dye-lots-matching-cushions-later/): Matching fabric from a previous order can come very close but is never guaranteed identical, because every dye lot shifts slightly in tone. - [Custom Cushion Covers in Caramel Bouclé With a Side Zipper](https://cushionguide.com/readings/caramel-boucle-cushion-side-zip-front-view/): Custom cushion covers with a zipper along the side panel come off without moving the bench, which matters most when you host. - [Replacement covers for a floor sofa: fit, color change and single pieces](https://cushionguide.com/guides/floor-sofa-replacement-covers/) *With color and care — Élodie* --- Written by Élodie Marchand (https://cushionguide.com/masters/elodie/) for CushionGuide (https://cushionguide.com/about/).
