Lowball vs. Old Fashioned Glass – What’s the Difference?

Lowball, rocks glass and Old Fashioned glass are often used for the same broad family of short tumblers. Lowball vs. Old Fashioned is therefore not a comparison between two strictly standardised glass types.

The more useful differences are capacity, shape, base and the actual serve.

Are Lowball and Old Fashioned glasses the same?

Very often yes, or close to it. Both terms usually refer to low, stemless glasses with a relatively broad opening and room for ice. “Rocks glass” is another common name in the same family.

Choose by capacity, diameter, base, weight and drink rather than the label alone.

What is a Lowball glass?

Lowball is a general term for a short tumbler used for whisky on the rocks, short cocktails and drinks with a large ice cube.

See the RCR Timeless Lowball 31 cl and lowball and whisky glasses.

What is an Old Fashioned glass?

Named after the cocktail, an Old Fashioned glass normally describes a short rocks/lowball tumbler. Smaller versions and larger Double Old Fashioned glasses both exist, so the name does not tell you the exact capacity.

What is a Double Old Fashioned?

DOF generally means a larger version of the short tumbler. The extra capacity can provide room for larger ice, garnish or slightly bigger short drinks. Exact sizes vary by manufacturer.

Which glass for an Old Fashioned cocktail?

Choose a glass that fits the finished cocktail and the ice you want to use. One large compact cube or sphere often works well for spirit-forward drinks.

Read large vs. small ice cubes and ice balls vs. large cubes.

Which glass for whisky neat?

A lowball works well for informal service. For focused tasting, a tulip-shaped glass can be more useful because it concentrates aromas differently.

See our whisky glass guide.

Heavy base or thin glass?

A heavy base gives a classic, substantial feel but is not required for a good drink. In professional operations, also consider durability, washing and ease of reordering.

What size should you choose?

There is no universal correct size. Start with the drinks and ice formats actually on the menu and test whether the glass gives enough room without making smaller serves look lost.

Lowball in restaurants and bars

A good lowball is highly versatile: whisky, Old Fashioned, Negroni on the rocks and many short signature cocktails can share the same glass family.
