A waistcoat takes about three quarters of a yard, and at any of the usual cloth widths — 54, 58 or 60 inches — the answer is the same. Order one full yard for a standard size and you will have a comfortable margin, including for a self-backed version. For an exact figure from your own measurements, use the calculator.
It is the smallest tailored garment on this site, and the only one where cloth width barely matters — the pieces are short and narrow enough to fit across almost anything.
| Size | 60″ | 58″ | 54″ |
|---|---|---|---|
| 36R | 0.77 | 0.77 | 0.77 |
| 38R | 0.78 | 0.78 | 0.78 |
| 40R | 0.80 | 0.80 | 0.80 |
| 42R | 0.81 | 0.81 | 0.81 |
| 44R | 0.83 | 0.83 | 0.83 |
Plain cloth, lining back. Shell only. The figure is identical at both widths because the pieces fit across either way — the layout never needs a second length.
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.
A waistcoat back is traditionally cut in lining, not shell. It sits under a jacket, it costs less, and a silk or cupro back slips more easily over a shirt. That is what the table above assumes.
A self-backed waistcoat — back cut in the suiting itself — is worth it if the waistcoat will ever be worn without the jacket. It takes 0.88 yards rather than 0.80 at a size 40R, so allow an extra tenth of a yard.
| Cloth | Size 40R at 60″ | Extra |
|---|---|---|
| Plain | 0.80 yd | — |
| Stripe | 0.92 yd | +15% |
| Check / plaid | 1.00 yd | +25% |
A patterned waistcoat crosses the one yard mark, which in practice means buying a yard and a quarter.
If you are ordering cloth for a three-piece suit rather than a waistcoat on its own, do not add these figures together — see the three-piece page, where the waistcoat pieces slot into the jacket layout and cost far less than they would separately.
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 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 here comes from an actual arrangement of actual pattern pieces.
