German Number Decoder
Build any German number from 0 to 100 and hear it spoken in a real German voice. See the units-before-tens flip that makes 21 einundzwanzig (one-and-twenty), and decode the Berlin prices, platforms and quantities you actually meet.
A free tool that builds and speaks German numbers for visitors to Berlin.
Use this free Berlin tool to get comfortable with German numbers before a bakery queue or a platform announcement catches you out. Slide to any number, watch the word build with the units-before-tens flip marked in colour, and press play to hear it in a real German voice.
What this tool does
The German Number Decoder builds any number from 0 to 100 in front of you, colours the units-before-tens flip so you can see why 21 is einundzwanzig, and plays a real German voice clip so you know what it sounds like out loud.
How to read a German number
German says the small digit first and joins it with und, so 21 is einundzwanzig (one-and-twenty) and 67 is siebenundsechzig (seven-and-sixty). Read the word right to left and it lines up with English. The tool marks the unit and the ten in different colours so the flip stops catching you out.
Prices, platforms and the Pfand
A German price uses a comma for the cents, so 3,50 is drei fünfzig. A platform is a Gleis, and U-Bahn and S-Bahn lines are just the plain digit. The tool includes the real Berlin numbers you meet first: a single ticket, a platform call, and the 25 cent Pfand on a bottle.
Where it helps in Berlin
This is the number practice that pays off at a bakery counter, a market stall, a Späti, and on the platform at Hauptbahnhof. Pair it with the full guide for the situations and phrases that go around the numbers.
