A fluitje is usually 20 cl, a vaasje (a regular glass) 25 cl and a half litre 50 cl. Names vary by pub and region, but the sizes are on the menu. And the price per sip often differs more than the price per glass.

How many cl is a fluitje, a vaasje and a pint?
In the Netherlands lager comes in many sizes: a fluitje of around 20 cl, a vaasje or regular glass of 25 cl, a larger glass of 30 or 40 cl and a half litre. Specialty beer often comes in a 33 cl bottle or glass. Apart from a one-litre pitcher, half a litre is the biggest size you'll meet.

Which size is cheapest per sip?
A fluitje looks cheap, but per sip it costs 18% more than a half litre: €4.44 versus €3.75 per 25 cl. That is what a menu hides if you only look at the price per glass.
How to convert a beer price to 25 cl
One menu lists a fluitje for €3.00, another a half litre for €6.50. Which is cheaper? Convert every price to a 25 cl glass: price ÷ volume × 25. The €3.00 fluitje (20 cl) then costs €3.75 per 25 cl. The €6.50 half litre costs €3.25 per 25 cl. So here the big one is cheaper per sip.
What makes it hard: for 54% of the beers we read, the menu lists no size. We then use that beer's usual size and mark it as an estimate (≈).
And the deal score?
In the app we don't just look at price, but at the beer itself too: a heavy specialty beer is different from a light lager. The deal score is alcohol% × (cl ÷ 25) ÷ price. The higher, the more you get for your money. If a menu lists no size, we calculate per glass and list that beer separately, so it never ends up on top unfairly.
