Fabric vs Supplies Yardage in Upholstery: What Counts as Yardage?

Here's something that catches shops off guard, especially early on: upholstery involves more than just the main face fabric. There's the decking under the cushions, the cambric dust cover on the bottom, arm caps, pull strips, and sometimes a muslin underlayer. All of these are fabrics. But they don't all belong in the "fabric yardage" line of your quote.

Getting this distinction wrong costs you money in two ways. Either you're eating the cost of secondary materials because you didn't charge for them, or you're confusing clients by including non-face-fabric yardage in a number they're going to use to shop your price.

Let's break it down clearly.

TL;DR

Upholstery Supplies yardage depends on fabric width, construction details, pattern repeat, and nap direction.
Plain 54-inch fabric requires a baseline calculation plus 10-15% waste allowance for a standard upholstery supplies job.
Patterned fabric adds 20-35% to base yardage depending on repeat size and the number of cutting zones that must align.
Directional fabrics add 15-25% over plain fabric because layout optimization is restricted by nap direction.
Always verify fabric width before finalizing yardage; COM fabric often comes in non-standard widths.
Calculating yardage at the quote stage, not mid-job, eliminates reorders and protects your profit margin.

What Counts as Primary Fabric Yardage

Primary yardage is the face fabric, the material the client chose, the one that determines the look of the finished piece. This is what your quote's "fabric yardage" figure should refer to.

Primary fabric includes:

All visible upholstered surfaces (outside back, inside back, arms, seat, front rail, base)
Seat and back cushion covers (top, bottom, boxing, zipper panel)
Decorative skirt, if part of the design
Welting, if cut from the same face fabric (often it is)
Welt cording, if self-fabric

When a client provides COM (customer's own material), the primary yardage number is what tells them how much to bring.

Secondary Fabrics That Are Supplies, Not Yardage

These materials are part of every job but shouldn't be folded into the "face fabric yardage" figure. They belong as separate line items in your quote, either itemized or folded into your labor/materials line.

Decking fabric: The less-expensive fabric used under seat cushions where it won't be visible. Typically a cotton or poly blend. A standard sofa uses 2 to 3 yards of decking. If you're not charging for it separately, you're eating that cost.

Cambric dust cover: The black woven fabric tacked to the bottom of upholstered pieces. A standard sofa bottom uses 1.5 to 2 yards. Cost is low per yard, but on 30 jobs a month it adds up. Shops that don't charge separately for cambric lose $15 to 25 per job, that's $300 to 500 per year at a modest job volume.

Arm caps: Some pieces use a small piece of heavier fabric on the arm tops to protect the face fabric from wear. Arm caps are usually cut from scraps or a separate inexpensive fabric. If ordered separately, they're supplies.

Pull strips: Tacking strips of burlap or other material used during installation. Supplies.

Muslin underlayer: If you use a muslin interliner before the face fabric, that's materials cost, not face fabric yardage.

How to Charge for Secondary Fabrics

There are two approaches that both work:

Itemize them separately: Line item the decking yardage, the cambric, and any other secondary materials with their own costs. Clients appreciate the transparency, and it makes material cost visible rather than buried.

Roll them into a materials fee: Add a flat "materials and supplies" line to your quote that covers all secondary fabrics, foam, padding, and notions together. Simpler for the quote, but less transparent.

Whatever you do, don't include these materials in the main fabric yardage number and then price them as if they were face fabric. A yard of decking cotton is not the same price as a yard of Sunbrella or Crypton.

Arm Caps: When They Are Primary Fabric

If the client wants arm caps made from the face fabric, they absolutely count as primary yardage. A pair of standard arm caps in face fabric adds about 0.25 to 0.5 yards depending on the arm size. This is small but easy to forget when you're calculating a big sofa, and forgetting it is how you end up cutting a little short.

For your upholstery quote generator, make sure your template distinguishes face fabric yardage from secondary fabric yardage. The distinction protects you and keeps your quotes professional.

Calculating Total Materials Cost

The complete materials cost for an upholstery job includes:

Face fabric yardage x price per yard
Decking fabric (2 to 4 yards per sofa, priced separately)
Cambric (1.5 to 3 yards, priced separately)
Foam replacement (if included in scope)
Padding and batting (priced as supplies)
Notions: zippers, cord, tack strips, staples

When you calculate this way, you'll find that secondary materials often add $25 to 60 to the true cost of a sofa job. If you're quoting fabric-only and not accounting for these, the gap comes out of your margin.

For the upholstery fabric order calculator, you can track all of these separately so your material cost per job is accurate, not approximated.

Frequently Asked Questions

What fabric supplies go into an upholstery job?

Beyond the main face fabric, a typical upholstery job includes decking fabric (under cushions), cambric dust cover (bottom lining), possibly a muslin underlayer, pull strips, and arm caps. Each of these is a real materials cost that should be accounted for in your quote, either as line items or as part of a materials and supplies charge.

Should I include arm caps in my fabric yardage?

If arm caps will be cut from the same face fabric as the rest of the piece, yes, add 0.25 to 0.5 yards to your main yardage calculation. If arm caps will be made from a separate protective fabric or the client isn't asking for them, they belong as a separate materials line item or omitted from the quote entirely.

How do I charge for decking and dust cover in upholstery?

Price them as materials, not as face fabric. Decking fabric typically costs $3 to 6 per yard, very different from face fabric at $20 to 80 per yard. Either itemize them with their own cost per yard, or roll them into a flat materials fee that covers all secondary fabrics and notions. Either approach is professional. What's not professional is forgetting to charge for them at all.

What is the biggest factor in yardage variation for this piece?

Pattern repeat is the biggest source of yardage variation. On plain fabric, the baseline calculation plus a 10-15% waste buffer is usually sufficient. Add a 13-inch pattern repeat and you may need 15-20% more. Add a 27-inch pattern repeat and the additional yardage can be 25-35% over the plain fabric calculation. Nap direction is the second-largest factor, typically adding 15-25% over plain fabric because layout optimization is restricted.
