Whether you’re keeping track of your alcohol intake for health reasons, part of a moderation challenge, or just curious about what’s in your pint, understanding how many units are in a Guinness is a smart step. Guinness is one of the most iconic beers in the world—known for its dark color, creamy head, and smooth, almost coffee-like taste. But how does it stack up when it comes to alcohol units?
In this guide, we’ll break down how many units are in a pint, can, or bottle of Guinness, compare it to other beers, and help you understand what that means for responsible drinking.
What Is an Alcohol Unit?
Before diving into Guinness specifically, it’s important to understand what an alcohol unit actually is.
In the UK, 1 alcohol unit equals 10ml (or 8g) of pure alcohol. The number of units in a drink is calculated using the following formula:
Strength (ABV) × Volume (ml) ÷ 1000 = Units
So, if a drink is 4% ABV and the serving size is 500ml, the number of units would be:
4 × 500 ÷ 1000 = 2 units
What’s the Alcohol Content of Guinness?
The standard Guinness Draught has an Alcohol by Volume (ABV) of 4.1% in the UK. Other versions, like Guinness Extra Stout, can be stronger (around 5.6% ABV), so always check the label.
Here’s a quick breakdown for the most common formats of Guinness:

A pint of Guinness Draught (which is 568ml at 4.1% ABV) contains approximately:
4.1 × 568 ÷ 1000 = 2.33 units
That means if you’re following the UK Chief Medical Officers’ guidelines, which recommend no more than 14 units per week, you could drink about:
6 pints of Guinness a week (spread out over several days) and stay within the recommended limit.
Comparing Guinness to Other Beers
You might assume that Guinness, with its dark and rich appearance, is stronger than other beers—but that’s actually not true.

Why Guinness Might Be a “Lighter” Choice
Despite its full flavor and creamy texture, Guinness has a relatively low ABV compared to many lagers and craft beers. That makes it a popular choice for those who want a satisfying beer experience without consuming too much alcohol.
Plus, Guinness contains fewer calories than you might think—around 210 calories per pint, which is lower than many other full-strength lagers or ales.
Tips for Drinking Guinness Responsibly
Here are a few simple ways to enjoy your Guinness while staying within healthy limits:
- Track Your Units – Use a mobile app or online calculator to stay informed.
- Pace Yourself – Space your drinks over several days rather than binging.
- Alternate with Water – It helps you stay hydrated and reduces overall consumption.
- Choose Draught Over Stronger Versions – Guinness Draught has fewer units than Extra Stout.
- Know Your Limits – Everyone metabolizes alcohol differently—be aware of how it affects you.
Is Guinness Good for You?
Guinness has a long-standing reputation for being a “healthier beer” (thanks to slogans like “Guinness is Good for You”). While it’s not a health drink, it does contain small amounts of iron, antioxidants, and B vitamins. However, these benefits don’t outweigh the risks of excessive alcohol consumption.
As with any alcoholic beverage, moderation is key.
