The highball glass is a versatile staple for mixed drinks with a light, refreshing profile. But how much does it actually hold? Understanding the right volume helps home bartenders and pros keep every pour balanced and consistent.
Most highball glasses fall within the range of 240 ml to 350 ml. This is broad enough for classic cocktails such as , highballs, or vodka soda—providing enough room for plenty of ice and non-alcoholic mixers while keeping the drink refreshing and easy to sip.
Classic highball recipes—like the or rum and soda—use roughly 45 ml to 60 ml spirit, topped with 120 ml to 180 ml mixer, then filled with ice. A 300 ml glass usually leaves the ideal level of dilution and fizz.
While a highball glass typically holds 240 ml to 350 ml, a Collins glass is slightly taller and larger, often ranging from 350 ml to 420 ml. Both work for mixed drinks, but the highball’s slightly smaller size keeps balance in classic builds.
For most home or bar settings, a 300 ml highball glass remains the standard—blending comfort, presentation, and the best ratio of mixer to spirit.
