Type a number and its spelling will appear here.
Numbers from 0 to 20
The basis of everything. Note that sechzehn and siebzehn are shorter than sechs and sieben.
Your browser can’t read this language aloud — try Chrome, Safari or Edge.
The tens
Almost all end in -zig; only 30 is dreißig, with ß.
How numbers are built
Units first, then und and the tens: 21 is “one-and-twenty”. Tap to listen.
Hundreds, thousands, millions
Up to a million a number is one word. Million is separate and capitalised.
Rules worth knowing
German numbers are logical, but one habit twists everyone’s brain — the units come before the tens.
21 = einundzwanzig
From 21 to 99 the unit comes first, then und and the ten: einundzwanzig, siebenunddreißig. Written as one word.
37 ≠ 73
Siebenunddreißig (37) and dreiundsiebzig (73) are easy to mix up by ear: you hear the unit first, not the ten. When writing a number down, fill the digits right to left.
1 = eins / ein
On its own or at the end it’s eins (hunderteins); inside a number it’s ein (einundzwanzig, eintausend). Before a noun: ein Euro, eine Stunde.
16 = sechzehn, 17 = siebzehn
Sechzehn and sechzig drop the s; siebzehn and siebzig drop the en. The rest are regular: vierzehn, vierzig.
30 = dreißig
Only 30 ends in -ßig; the other tens end in -zig: zwanzig, vierzig, fünfzig.
1987 = neunzehnhundertsiebenundachtzig
Years before 2000 are read in hundreds: neunzehnhundert… The plain number 1987 is tausendneunhundertsiebenundachtzig. Everything below a million is one word.
2 = zwo
On the phone and at stations people often say zwo instead of zwei so it isn’t confused with drei.
Practice: test yourself
10 numbers per round. Start with 0–20, then move to bigger ones — numbers are hardest to catch by ear.

How to understand numbers by ear
- Learn 0–20 and the tens by heart — everything else is built from them.
- When writing a number you hear, write the unit first and the ten in front of it: “drei-und-vierzig” → _3 → 43.
- Read prices, house numbers and years aloud — a few every day.
- A few rounds of “Hear the number” every day: we recognise numbers more slowly by ear than by eye.
FAQ

Why do German numbers put the units before the tens?
It’s historical, like old English “four-and-twenty”. So 21 is einundzwanzig, “one-and-twenty”. Hundreds and thousands stay in the usual place: hunderteinundzwanzig (121).
Are big German numbers written as one word?
Everything up to 999,999 is one word: zweitausenddreihundertfünfundvierzig. Million and Milliarde are separate, capitalised words: zwei Millionen dreihunderttausend.
How do you say a year in German?
Years before 2000 are said in hundreds: 1987 — neunzehnhundertsiebenundachtzig. From 2000 they’re plain numbers: 2026 — zweitausendsechsundzwanzig.
What is zwo?
A spoken variant of zwei used on the phone, at stations or in the army so that zwei isn’t misheard as drei. In writing it’s always zwei.
