Loso, What is a standard drink?
Different countries measure your standard drink differently based on the level of pure alcohol in the drink. They sure don’t make it easy!
The World Health Organisation use 10 grams per standard drink. This is used in Ireland, Australia and New Zealand so we’ve used this measure.

Your tipple of choice not in the image above?
While we’ve shown how you can calculate your standard drinks below, the nice Australians have made life really easy by producing this simple to use guide covering an even wider range of drinks. All you have to do is look at the alcohol volume on your favourite tipple and pick the relevant picture in the guide. You can see the guide here.
Not sure of your glass size ?
Not sure what size the glasses you are using are? You can use a measuring jug or an empty drink container like a milk carton which has the measurement written on it to figure out your glass size.
How are standard drinks calculated ?
All alcohol must have the alcohol volume listed on the label. Usually the alcohol volume is shown as a percentage. The higher the alcohol volume % the higher the number of standard drinks. So a litre of vodka which is usually 40% volume has a lot more standard drinks than a litre of beer which may only have 3% volume. So to calculate your standard drinks there are two steps.
Multiply your quantity of drink by the alcohol volume and then by 0.79. So
1 glass of 140 ml of wine at 12% multiplied by 0.79 is 13.3 grams of alcohol.
Divide the 13.3 by 10 and this gives you 1.3 standard drinks.
Just pick one measure of standard drinks
Don’t get too hung up on the differences in standard drinks between countries. Just pick one measure, you feel most comfortable with and stick with this. We’ve shown what’s used in other countries in the useful information section.
