By keg size
The math is simple: liters divided by glass size. A 50-liter keg gives you 200 25-cl vaasjes, 250 20-cl fluitjes, or 100 50-cl glasses. A 30-liter keg gives you 120 vaasjes, 150 fluitjes, or 60 large glasses. A 20-liter keg gives you 80 vaasjes, and the 5-liter home-tap kegs give you 20 vaasjes.
In practice, you won't get that many. Each glass gets a two-finger head, the first glass after connecting the keg is often all foam, and there's always some beer left at the bottom of the keg. So allow for ten percent loss: a 50-liter keg is good for 180 vaasjes, and a 30-liter keg for just over 100.
By glass size
A vaasje in the Netherlands is 25 cl and is the standard in most pubs. A fluitje is 20 cl, a pint is 50 cl. If you pour into larger glasses, the keg empties twice as fast as when using fluitjes. Read about all the sizes in our article on beer glasses and the article about the pint.
For a party serving vaasjes, 50 liters is enough for about 180 glasses. Allow four to five glasses per guest for an evening, and that will be enough for forty guests. If there are beer drinkers who can easily put away eight, get a second keg.
How many kegs for a party?
Count the guests who drink beer, multiply by four or five glasses, then by the glass size, and add ten percent. For fifty guests with vaasjes, that's 50 times 4.5 times 0.25 liters, or 56 liters, plus loss, so 62 liters: one 50-liter keg and one 20-liter keg, or two 30-liter kegs. It's better to have a keg left over than to run dry at ten o'clock.
A keg stays good for three to five days after tapping if kept cold and under pressure. Make sure you have enough glasses: at a party, glasses don't come back, so allow two glasses per guest. Browse our beer glasses and read our article about renting or buying glasses.

Pressure that is too high, a keg that is too warm, or a greasy line. Read all about pouring on our page about pouring beer.
