UK Drink Drive Limit & Alcohol Calculator Data

Seven factors that determine your result

Weight
Body weight determines how alcohol distributes in the body — more weight means a lower blood alcohol concentration.
Sex
Men and women metabolise alcohol at different rates because of differences in body water content.
Age
Body water content declines with age, so the same amount of alcohol pushes peak BAC higher.
Amount
The amount of pure alcohol consumed is the main factor that determines your BAC result.
Strength
A higher strength (%) means more ethanol in the same drink serving.
Food
Food in your stomach slows alcohol absorption — drinking on an empty stomach can nearly double the peak BAC.
Time
The time of your first drink shows how BAC changes hour by hour and when you'll be sober again.

Tips for Responsible Drinking & Morning After Calculator

Practical tips for safer drinking

Pace yourself
Stick to the "one drink per hour" rule – your liver needs time to process alcohol.
Eat before and while drinking
A solid meal slows alcohol absorption – an empty stomach raises BAC faster.
Drink water
After each alcoholic drink, have a glass of water – it reduces dehydration and health risks.
Don't drive
Even small amounts of alcohol impair reaction time. If in doubt, call a taxi or stay overnight.
