How we figure this

The chart underneath this tool is the starting point: base yards per piece on 54-inch plain goods, average commercial frame sizes, one continuous piece with no fabric direction problems. It's the same set of numbers we use when someone sends over a fabric memo and asks what the order looks like — 0.75 yards for a drop-in seat, 6 yards for a club chair, 12 for a three-seat sofa, a yard per linear foot of banquette.

Three things move those numbers, and we apply them in that order. Roll width comes first, because the chart is built on 54-inch goods — 45-inch fabric needs about 30% more yardage and 36-inch needs about 50% more, since the narrower roll forces extra cuts across the same panels. Then the pattern repeat: matching motifs across cushions means every cut starts at the same point in the pattern and the fabric in between gets trimmed. We allow 10% for repeats up to 14 inches, 15% from 15 to 27 inches, and 25% at 28 inches and above.

Railroading works the other way. Running the goods sideways lets the roll width cover the length of a long shallow piece, which removes seams and takes roughly 10% off. We only apply it to the pieces where it's physically sensible — sofas, sectionals, benches, banquettes, headboards, and oversized ottomans — and only when you've set the repeat to solid, because a pattern that runs up the roll can't be turned 90 degrees without ending up sideways. The total then rounds up to the next half yard, because that's how fabric gets cut and sold.

The honest caveat: these are planning yardages, not cut tickets. Frame sizes vary more than people expect — two chairs described the same way in two catalogues can be 20 inches apart in seat depth, and skirts, contrast welt, and channel tufting all eat fabric that no average accounts for. The manufacturer's stated COM requirement for your exact frame always governs. If their card says more than we do, order what their card says.

When you've got a yardage that looks right, the next question is usually the frames. We supply commercial seating built for COM, so you can see what we stock in lounge seating or send the whole list over and get it priced with lead times and freight attached.
