How Much COM Fabric to Order for a Hotel Sofa, Sectional or Banquette
Order too little COM and production stops while you go back to the mill, usually for a different dye lot. Order far too much and you have paid for fabric nobody will use.
Neither outcome is necessary. The yardage is calculable, and the variables that move it are all knowable before you buy.
Quick reference: contract yardage by piece type
These figures assume 54 inch wide, plain, non-directional goods applied railroaded, which is the baseline nearly all published COM figures use. Adjust from here using the multipliers in the next section.
| Piece | Typical contract yardage |
|---|---|
| Upholstered chair seat pad | 0.5 yd |
| Fully upholstered side chair | 1.1 to 2 yds |
| Club or lounge chair | 4 to 6 yds |
| Club chair, high or privacy back | 6 to 8 yds |
| Ottoman | 2 to 3 yds |
| Loveseat | 7 to 10 yds |
| Three-seat sofa | 10.5 to 14 yds |
| Sleeper sofa | 14 to 18 yds |
| Sectional | Quote per configuration |
| Upholstered headboard | 5 to 13 yds, driven by style more than bed size |
| Banquette | 1 to 3 yds per linear foot |
Two notes on that table.
Headboards vary by style, not by bed size. A plain panel headboard for a king takes less fabric than a tufted, welted, wing-sided headboard for a queen. Do not size the yardage off the mattress.
Banquettes are quoted per linear foot, and the range is wide because back height and whether the outside back is upholstered change the number substantially. A low bench back with an unupholstered outside back sits near the bottom of the range. A tall tufted back with a finished outside back sits at the top.
The four things that change the number
1. Pattern repeat
The largest single variable. Matching a repeat across a piece costs fabric, and the cost scales with repeat size.
Add the vertical and horizontal repeat together to get the total repeat, then adjust. As a working guide, a total repeat in the region of fifteen inches on a 52 to 54 inch fabric adds roughly twenty five percent to the baseline requirement. Large repeats can add more.
Round up to the nearest half yard after adjusting.
2. Direction and nap
Velvets, many textured weaves and any fabric with a visible nap are directional. They have to be applied up the roll rather than railroaded, which typically adds around ten percent to the baseline requirement.
Some fabrics are the opposite case: woven or printed with the top of the design toward the selvage, meaning they are intended to be applied railroaded. Those usually should not be used for drapery, because the pattern will run sideways on a vertical panel.
3. Fabric width
The baseline is 54 inches. Narrower goods change the cut layout and can add materially to the requirement, sometimes more than the width difference alone suggests, because a narrow width can force an extra seam or waste a full panel per cut.
4. Railroading
Running fabric sideways can eliminate seams on wide pieces like sofa backs and long banquette runs, which often reduces yardage as well as improving appearance. Whether it is possible depends entirely on the pattern.
On a long banquette run, railroading is doing real work. Check it before specifying.
Leather is a different calculation
COL is bought by the hide and estimated in usable square feet, not yards. Hide size, shape, yield, natural scars and grain variation all affect how much usable material a hide actually provides.
The practical consequence: a leather that works beautifully on a small accent chair may not give the consistency or yield needed across a long sectional, where panels have to match. Ask for a hide yield estimate rather than converting from a yardage figure.
Always order overage
The calculated minimum is a minimum. Order above it.
Overage covers cutting variance, a flaw in the goods, a piece damaged in production, and the piece somebody discovers was left off the schedule after the fabric was ordered.
It also gives you attic stock. A chair damaged in year three can be repaired in the original fabric from the original dye lot rather than an approximate match that will be visible from across the room. On a large program this is the difference between a repair and a replacement.
The right overage figure depends on repeat size and piece count, so agree it with your manufacturer rather than applying a flat percentage across everything.
Why the shortfall scenario is worse than it looks
If insufficient yardage arrives at the factory, three things happen in sequence.
Production stops. Your piece cannot be cut, and the slot it was occupying on the schedule gets filled by somebody else's order.
You go back to the mill. If the original dye lot has been sold through, the replacement yardage comes from a different lot.
You now have a visible mismatch. Dye lot variation across a set of matching pieces is exactly the kind of thing that gets flagged in a brand inspection and is not usually credited by the mill, because dye lot variation is standard trade terms.
Some manufacturers also charge a handling fee to run the special procedures needed to determine whether an order can be completed with short yardage.
All of that is avoided by confirming the number before the purchase order goes to the mill.
The fastest way to get this right
Send the manufacturer the fabric details and the piece list before you buy anything.
For each fabric:
- Name, pattern number, color and mill
- Width
- Vertical and horizontal repeat
- Whether it is railroaded, up the roll or non-directional
- Content and any performance data
Plus the piece list with quantities and the shop drawings or model numbers.
Ten minutes of yardage math against your actual drawings is worth more than any chart, including the one above. Send it to us and we will confirm the requirement, flag anything that will not work on the piece it has been assigned to, and recommend an overage figure for that specific program.
Frequently asked questions
How much fabric does a hotel sofa need?
On 54 inch plain non-directional railroaded goods, a three-seat contract sofa typically needs 10.5 to 14 yards and a sleeper sofa 14 to 18. Pattern repeat, fabric width, nap and railroading all change the number, so confirm against the actual piece before ordering.
How much fabric does a banquette need?
Banquettes are estimated per linear foot, typically 1 to 3 yards per foot. Back height and whether the outside back is upholstered drive most of the range. A tall tufted back with a finished outside back sits near the top.
How does pattern repeat affect yardage?
It increases it, sometimes substantially. Add the vertical and horizontal repeats together for the total repeat. A total repeat around fifteen inches on a 52 to 54 inch fabric adds roughly twenty five percent over the baseline, and larger repeats add more.
Do velvets need more fabric?
Yes. Velvets and other napped or directional fabrics have to be applied up the roll rather than railroaded, which typically adds around ten percent to the baseline requirement.
How much extra COM fabric should I order?
More than the calculated minimum, with the exact figure agreed with your manufacturer. Overage covers cutting variance, flaws, production damage and attic stock so later repairs can be made in the original dye lot.
Can I use a yardage chart I found online?
Only if it is a contract chart. Most published yardage charts are residential slipcover charts and run considerably high against commercial seating, which is built and cut differently.
How is leather yardage calculated?
It is not calculated in yards. Leather is bought by the hide and estimated in usable square feet, with hide size, shape, yield, scars and grain variation all affecting the usable amount. Ask for a hide yield estimate rather than converting from a fabric yardage figure.
Send us the fabric details and the piece list.
We will confirm yardage against your actual drawings, flag anything unsuitable for the piece it has been assigned to, and recommend an overage figure for your program. Before the purchase order, not after the fabric arrives.
