Quick, what does one serving of your favorite drink look like? It’s not as easy to quantify as we think, and chances are you’re probably putting more calories in your body than you realize.

On average, it takes about an hour for the body to metabolize one standard drink as defined by U.S. guidelines: 12 ounces of 5% beer, 5 ounces of 12% wine or 1.5 ounces of 40% liquor. Obviously this varies with body weight, sex, age, individual metabolic rate, the type and strength of the alcohol, whether you’ve eaten recently and what medications you take, but if those serving sizes sound small compared to what the bartender serves or what you typically pour yourself, just wait until we show you some of your favorite cocktails.

To help you log those boozy beverages more accurately, we’re showing you what one standard serving of 10 different alcoholic beverages really looks like (at least according to the International Bartender’s Association) and the calories each serving contains.
