A two-piece suit takes about 3¾ to 4 yards of 58- or 60-inch cloth, or 4 to 4¼ yards at 54 inches. Order 4 yards for a standard size and you will have enough for a jacket and trousers with normal seam allowances. Patterned cloth that has to be matched across seams needs more. For an exact figure from your own measurements, use the calculator.
That is the short answer, and for most orders it is the only one you need. But the honest answer is that yardage depends on four things: the size being cut, the width of the cloth, whether the cloth has a pattern or a nap, and how the pieces actually fit across the width. The tables below cover all four.
Shell cloth only — lining and canvas are listed separately further down. These figures come from laying the real pattern pieces out across the cloth, not from a rule of thumb.
| Size | 60″ | 58″ | 54″ |
|---|---|---|---|
| 36R | 3.7 yd | 3.7 yd | 3.9 yd |
| 38R | 3.7 yd | 3.9 yd | 3.9 yd |
| 40R | 4.0 yd | 4.0 yd | 4.1 yd |
| 42R | 4.0 yd | 4.0 yd | 4.1 yd |
| 44R | 4.1 yd | 4.1 yd | 4.2 yd |
Regular lengths, plain cloth, flat-front trousers, no turn-ups. Round up when you order — cloth is sold in whole and half yards, and no tailor has ever regretted a spare quarter yard. Above 44, or on a fuller cut, the pieces can stop fitting across the width and the requirement jumps rather than creeps; run your own measurements if you are near that line.
These are standard sizes on default settings. Bespoke work rarely is — for your client’s actual measurements, your cloth’s repeat and your own style options, run it through the calculator, which also draws the cutting layout.
Yardage is not a fixed quantity of cloth — it is a length of a particular width. The question that decides everything is how many pattern pieces fit side by side across the cloth before you have to start a new length.
On 60-inch cloth, both trouser fronts and both trouser backs usually fit across in a single run. Lose a few inches of width and one leg no longer fits, so it moves onto a second length, and the requirement jumps by the better part of a yard in one step. This is why yardage does not scale smoothly with size, and why a chart that ignores width is close to useless.
Suiting is almost always woven at 58 to 60 inches, with some Italian mills at 54. Narrower cloth — 45-inch dress goods, for instance — will need substantially more than the figures above, because far fewer pieces fit across.
Plain cloth can be folded and cut two layers at a time, so mirrored pieces cost nothing extra. Patterned cloth usually cannot: it is cut single-layer so the pattern runs true across every seam, and you buy extra length to line the repeat up.
| Cloth | Size 40R at 60″ | Extra |
|---|---|---|
| Plain | 3.95 yd | — |
| Stripe | 4.54 yd | +15% |
| Check / plaid | 4.94 yd | +25% |
A large repeat costs more than a small one, because you lose up to a full repeat at each seam zone. A 6-inch check repeat pushes the same suit to about 5.3 yards; a 12-inch repeat to nearly 6.
Velvet, corduroy, moleskin, brushed flannel and any directional design must be cut with every piece the same way up, or the panels will shade differently once made up. That rules out nesting the trouser legs head to toe, which is how a cutter normally saves width. On smaller sizes it costs nothing, because the legs fit across either way — but on a 44 it can add more than a yard.
Shell cloth is not the whole order. For a standard two-piece suit, allow:
Lining does not need pattern matching, so none of the extra above applies to it.
A two-piece suit is more pieces than people expect, which is why yardage estimates that treat a jacket as one rectangle run so far off. The shell alone includes two backs, two side bodies, two forepart fronts, two top sleeves and two undersleeves, two front facings, a collar and collar stand, pocket flaps and welts — then four trouser legs and a waistband.
Every one of those has to be placed on the cloth without overlapping, respecting the grain. That placement, not a multiplier, is what actually determines how much you buy.
The panel widths behind these numbers were cross-checked against Winifred Aldrich's Metric Pattern Cutting for Menswear and Alan Poulin's Tailoring Suits the Professional Way, then laid out piece by piece across the chosen cloth width to see how many lengths the layout actually needs.
They are estimates, and they should be treated as such. Seam allowances, house style and a cutter's own habits all move the number. What they will not do is guess: every figure on this page comes from an actual arrangement of actual pattern pieces.
