Fourteen units of alcohol is the UK’s recommended weekly limit for adults, and it works out to roughly six pints of average-strength beer, a bottle and a half of wine, or 14 single measures of spirits. One UK unit equals 10ml (8g) of pure ethanol, so 14 units means 140ml of pure alcohol spread across an entire week.
That number is smaller than most people expect. Here’s exactly what it looks like for every common drink.
What 14 Units Looks Like in Beer and Cider
How many pints you get depends entirely on the strength of what you’re drinking. A UK pint is 568ml, and you can calculate units for any drink with a simple formula: multiply the volume in ml by the ABV percentage, then divide by 1,000.
- 3.6% ABV (session lager or light cider): 2 units per pint, giving you 7 pints for the week.
- 4% ABV (standard lager): about 2.3 units per pint, so roughly 6 pints for the week.
- 5% ABV (premium lager or craft beer): 2.8 units per pint, meaning just under 5 pints covers your entire weekly allowance.
Many popular craft beers now sit between 5.5% and 7% ABV. At 6.5%, a single pint contains 3.7 units, and fewer than four pints would use up all 14 units. If you drink stronger IPAs or stouts, the weekly budget shrinks fast.
What 14 Units Looks Like in Wine
Wine is where the numbers surprise people most. A standard 750ml bottle of 12% wine contains 9 units, so a bottle and a half hits roughly 13.5 units. That’s your entire week in just two evenings if you split a bottle each time.
Glass sizes matter too. A small 125ml glass of 12% wine is 1.5 units. A large 250ml glass of the same wine is 3 units, exactly double. Many restaurants and bars pour 175ml as a “medium” glass, which comes to about 2.1 units at 12% ABV. At that size, roughly seven glasses account for 14 units.
Wine strength has crept up in recent decades. Plenty of reds sit at 13.5% or 14% ABV now. A 250ml glass of 14% wine is 3.5 units on its own, meaning just four large glasses would take you to your weekly limit.
What 14 Units Looks Like in Spirits
A single pub measure of spirits (25ml at 40% ABV) is exactly 1 unit, making the maths easy: 14 singles equals 14 units. In parts of Scotland and Northern Ireland, a single measure is 35ml, which works out to 1.4 units per serve, so 10 singles would reach the limit.
Home pours are almost always larger than pub measures. If you’re free-pouring gin, whisky, or vodka without a jigger, you’re likely serving yourself 50ml or more each time. A 50ml double is 2 units, so seven home-poured doubles could easily hit 14 units. Cocktails are harder to track since many contain two or three spirits plus liqueurs, and a single cocktail can easily reach 3 or 4 units.
The Calorie Side of 14 Units
Alcohol is calorie-dense, and 14 units adds up quickly. A pint of 5% beer contains up to 222 calories, so five pints in a week is over 1,100 calories from beer alone. A 175ml glass of 12% wine runs up to 158 calories, putting seven glasses at around 1,100 calories as well. Spirits are more efficient at roughly 100 calories per double (50ml), but mixers like tonic, cola, or juice can easily double that per drink.
For context, 1,100 weekly calories from alcohol is roughly equivalent to five or six chocolate bars.
How Your Body Processes It
Your liver clears alcohol at a steady rate of roughly one unit per hour. That speed doesn’t change with coffee, food, or cold showers. If you drink seven pints of 4% lager on a Saturday night (about 16 units), your body needs around 16 hours to fully process the alcohol. Someone finishing their last drink at midnight could still have alcohol in their system past 4pm the next day.
This is why the UK guidelines recommend spreading 14 units over three or more days rather than concentrating them in one or two sessions. Drinking the same total amount in a single evening places a very different burden on your liver, brain, and cardiovascular system than distributing it across the week.
Why 14 Units Is the Limit
The 14-unit guideline comes from the UK Chief Medical Officers and applies equally to men and women. It’s set at the level where long-term health risks remain low. Regularly exceeding 14 units per week over 10 to 20 years raises the risk of serious conditions including mouth, throat, and breast cancer, stroke, heart disease, liver disease, brain damage, and damage to the nervous system. Regular heavy drinking is also strongly linked to worsening mental health, self-harm, and suicide.
The threshold isn’t a hard line between safe and dangerous. Risk increases gradually as consumption rises. But 14 units is the point below which the overall statistical risk stays relatively small.
UK Units vs. US Standard Drinks
If you’re comparing notes with American guidelines, the measurements don’t translate one-to-one. A UK unit contains 8g of pure alcohol, while a US “standard drink” contains 14g. That means one US standard drink equals 1.75 UK units. The US recommendation of no more than two drinks per day for men (14 per week) actually works out to about 24.5 UK units per week, a significantly higher threshold than the UK’s 14-unit guideline.
How to Calculate Units for Any Drink
The formula works for anything: multiply the drink’s volume in ml by its ABV (as a number, not a percentage), then divide by 1,000. A 330ml bottle of 4.5% beer, for example: 330 × 4.5 ÷ 1,000 = 1.49 units. A 750ml bottle of 13% wine: 750 × 13 ÷ 1,000 = 9.75 units.
Most cans and bottles in the UK now print the unit count on the label. If you’re pouring at home, the main variable is how much liquid actually goes into the glass. A kitchen measuring jug or a spirit measure takes the guesswork out.
