Stand in a store’s glassware aisle and you will find tall glasses labeled “highball” right next to nearly identical ones labeled “Collins,” and it is fair to wonder whether the difference is real or just marketing. The short version: the difference is real but tiny, the two are used interchangeably behind almost every bar, and for your home you need exactly one of them.
This is the practical comparison. The actual difference between a highball and a Collins glass, where the rocks glass fits, which cocktails go in each, and the honest answer on whether you need to own both (you do not).
Who this is for
You are stocking a home bar, or you saw a recipe call for a “Collins glass” and want to know if the highball glasses you already own will work. They will. This guide sorts out the small real differences so you can buy one set of tall glasses and stop worrying about it.
This is part of our glassware guides. For the full lineup, see types of cocktail glasses, and for the tall glass specifically, our highball glass guide covers which ones to buy.
TL;DR: highball vs collins glass
- They are nearly the same glass. Both are tall, straight-sided tumblers, and bartenders use them interchangeably.
- The Collins is taller and narrower (about 10 to 14 oz). The highball is shorter and wider (about 8 to 12 oz).
- They overlap around 10 to 12 oz, which is why most bar glasses of either name are about 12 oz.
- The narrower Collins holds carbonation slightly longer because it has less surface area on top.
- You do not need both. One set of tall 12 to 14 oz glasses covers every drink either one is used for.
- The rocks glass is the different one: short and wide, for spirit-forward drinks like an Old Fashioned.
The quick answer: are they the same?
For all practical purposes, yes. A highball glass and a Collins glass are both tall, straight-sided tumblers built for drinks served long over ice, and most bartenders reach for whichever is closer without thinking about it.
The one genuine difference is proportion. A Collins glass holds about 10 to 14 ounces and is cylindrical, narrower and taller than a highball, a shape that keeps a carbonated drink fizzy a little longer by reducing its surface area. A highball glass holds about 8 to 12 ounces and is a touch shorter and wider. They overlap right in the middle, around 10 to 12 ounces, so in real life the two are used interchangeably. If a recipe calls for one and you own the other, use it.
Highball vs collins vs rocks glass
Here is where all three tall-and-short tumblers sit next to each other, so you can place any of them at a glance. This is the table the other comparisons skip.
| Glass | Shape | Typical size | Holds fizz | Typical drinks |
|---|---|---|---|---|
| Highball | Tall, straight, medium width | 8-12 oz | Good | Gin and tonic, rum and Coke, Jack and Coke, whiskey soda, Paloma |
| Collins | Tall, straight, narrower | 10-14 oz | Best (less surface area) | Tom Collins, John Collins, gin fizz, long sparkling drinks |
| Rocks / old fashioned | Short, wide | 6-10 oz (double 12-16) | N/A | Old Fashioned, Negroni, whiskey neat or on the rocks |
The highball and Collins are two versions of the same idea. The rocks glass is the genuinely different one: short and wide, made for spirit-forward drinks you sip, not tall drinks full of mixer. Our whiskey glasses guide covers that short glass in depth.
The highball glass
A highball glass is a tall tumbler holding roughly 8 to 12 ounces, taller than a rocks glass and a little shorter and wider than a Collins. The name comes from the drink category: a “highball” is any spirit topped with a larger amount of non-alcoholic mixer, served over ice in a tall glass.
That covers a huge share of everyday drinks:
- Gin and tonic
- Rum and Coke (and the lime version, the Cuba Libre)
- Jack and Coke and other whiskey-and-cola drinks
- Whiskey soda and highball (the Japanese whisky highball)
- Dark and Stormy, Paloma, screwdriver
If you make simple two-ingredient drinks with a spirit and a mixer, the highball is the glass you reach for most. It is the workhorse of a home bar, which is why our highball glass guide treats it as the first tall glass worth buying.
The collins glass
A Collins glass is the highball’s slightly taller, narrower cousin, holding about 10 to 14 ounces. It takes its name from the Tom Collins, the gin, lemon, sugar, and soda drink it was built for, and the John Collins made with whiskey. The taller, slimmer shape suits drinks with more mixer or more carbonation, because the smaller surface area on top lets the bubbles last.
Use a Collins glass for:
- Tom Collins and John Collins
- Gin fizz and other fizzes
- Tall, citrus-forward or sparkling drinks that need room for soda and ice
In practice, a highball glass does all of this fine, and a Collins glass makes a perfectly good gin and tonic. The distinction matters to a bar buying thousands of glasses and stocking specific lines; at home it rounds off to “a tall glass.”
Where the rocks glass fits
The one glass in this conversation that is actually different is the rocks glass, also called an old fashioned or lowball glass. It is short and wide, usually 6 to 10 ounces (a double old fashioned runs 12 to 16), and it is built for the opposite kind of drink: spirit-forward, low on mixer, sipped slowly.
An Old Fashioned, a Negroni, or whiskey neat or over a big cube all belong in a rocks glass, not a tall one. So the real glassware decision for a home bar is not highball versus Collins, it is tall versus short: one tall glass (call it a highball or a Collins) and one rocks glass cover almost everything. Our types of cocktail glasses guide lays out that full short list.
Do you need both a highball and a collins glass?
No. This is the honest part the glass sellers leave out: because a highball and a Collins are nearly the same glass and are used interchangeably, buying both is buying the same thing twice.
For a home bar, one set of tall glasses in the 12 to 14 ounce range covers every drink either name is used for. You can make a Tom Collins, a gin and tonic, a Jack and Coke, or pour water and iced tea, all in the same glass. Add a set of rocks glasses for spirit-forward drinks, and your tall-and-short bases are covered.
Buy 6 to 8 tall glasses and 6 rocks glasses and you are set for almost any drink you will host. Libbey makes sturdy, inexpensive versions of both that are perfect for parties; Schott Zwiesel and similar make nicer, break-resistant ones if you want a step up. For the whole setup, our bar cart guide covers what else to stock.
What to skip
- Buying both a highball set and a Collins set. They are the same glass. Pick one tall glass and move on.
- Worrying about the exact ounce difference. A 12 to 14 ounce tall glass handles every long drink. Nobody has ever ruined a gin and tonic by serving it in a Collins glass instead of a highball.
- A dedicated zombie glass unless you make tiki drinks often. A Collins glass stands in for the occasional Zombie.
- Specialty tall glasses for every drink. One good tall glass and one rocks glass do the work of a cabinet full of named shapes.
FAQ
Is a Collins glass the same as a highball glass? Nearly. Both are tall straight tumblers used interchangeably; the Collins is slightly taller and narrower (10 to 14 oz) and the highball a bit shorter and wider (8 to 12 oz). For home use, one covers both.
What is a Collins glass used for? Tall carbonated or citrus drinks like the Tom Collins, John Collins, and gin fizz, plus water, iced tea, and juice. Its narrow shape keeps fizz longer.
Is Jack and Coke a highball? Yes. A highball is a spirit plus a larger amount of mixer over ice in a tall glass, so whiskey and cola is a classic highball.
Do you need both a highball and a collins glass? No. They are nearly identical, so one set of tall glasses covers every drink either is used for.
Why is it called a zombie glass? It is named after the Zombie, a strong tiki cocktail. The drink is large, so the glass is even taller than a Collins.
What is another name for a Collins glass? It is often just called a tall glass or tall tumbler and is used interchangeably with the highball. It takes its own name from the Tom Collins cocktail.
What this earns you
The highball-versus-Collins question has a freeing answer: they are the same glass in two slightly different sizes, so you only need one. Buy a set of tall 12 to 14 ounce glasses, add a set of rocks glasses for spirit-forward drinks, and you can pour almost any cocktail correctly without a cabinet full of near-duplicate shapes. Match tall drinks to a tall glass, short drinks to a short one, and skip the rest.
