| Type | Typical size | Covers | Downside |
|---|---|---|---|
| Rocks (old fashioned) | 9–10 oz | Old fashioned, negroni, whiskey neat or on ice | Too small for long drinks |
| Highball | 10–12 oz | Highball, gin & tonic, mojito | Wrong shape for short cocktails |
| Martini glass | 6–8 oz today (vintage 3–5 oz, oversized 10 oz+) | Martini, Manhattan | Single-purpose and easy to knock over |
| Coupe | 5–7 oz | Daiquiri, sidecar | Poor for fizzy or long drinks |
