Als vs Wie? | Comparison in German

Even native German speakers mix up als and wie sometimes — but the rule that decides between them is actually simple. It all comes down to one question: are the two things you're comparing equal, or not?

The Core Rule

• wie = comparing two equal things ("as ... as")
• als = comparing two unequal things ("more/less ... than")

That's the whole rule. Everything else is just applying it correctly.

Comparison with "wie" (Equal Things)

When two things are the same in some way, German uses the pattern so + adjective + wie, with the adjective staying in its base form (no comparative ending).

• Mein Bruder ist so groß wie ich. — My brother is as tall as me.
• Diese Übung ist so schwer wie die letzte. — This exercise is as difficult as the last one.
• Sie spricht so gut Deutsch wie eine Muttersprachlerin. — She speaks German as well as a native speaker.

To say things are not equal in this same structure, just negate it: Mein Bruder ist nicht so groß wie ich. — My brother is not as tall as me.

Useful Phrases With "wie"

A few fixed expressions use wie outside the strict "so...wie" pattern, and are worth memorizing as-is:

• so schnell wie möglich — as fast as possible
• so bald wie möglich — as soon as possible
• genauso... wie — just as... as (a slightly stronger version of so...wie)
• wie immer — as always

Comparison with "als" (Unequal Things)

When one thing is more or less than another, German uses the Komparativ form of the adjective (usually adjective + -er) followed by als.

• Mein Bruder ist größer als ich. — My brother is taller than me.
• Diese Übung ist schwerer als die letzte. — This exercise is more difficult than the last one.
• Berlin ist größer als München. — Berlin is bigger than Munich.

This is the single most common mistake for English speakers: because English uses "than" here, and "than" sounds a little like "then," learners often reach for wie by habit. Remember: comparative adjective (-er) always pairs with als, never wie.

The Most Common Mistake to Avoid

❌ Er ist größer wie ich. (Very common in casual/regional spoken German, but not grammatically correct standard German.)
✅ Er ist größer als ich.

You may well hear größer wie from native speakers in casual conversation — it's a widespread colloquialism in some regions — but for writing, exams, and correct standard German, always pair a comparative with als.

Quick Reference Table

• Equal: so + Adjektiv (Grundform) + wie → so schnell wie
• Unequal: Adjektiv + -er + als → schneller als

Frequently Asked Questions

When do I use "als" vs "wie" in German?

Use wie when comparing two equal things (so + adjective + wie = "as...as"). Use als when comparing two unequal things, together with the comparative form of the adjective (adjective + -er + als = "more...than").

Why is "größer wie" wrong?

A comparative adjective (one ending in -er, like größer) must be followed by als, not wie. "Größer wie" is a common colloquialism heard in casual speech in some regions, but it is not correct standard German.

What is the "so...wie" structure used for?

It's used to say two things are equal: so + the adjective in its base form + wie. For example, "so groß wie" means "as tall as," with no comparative ending on the adjective.

Is "als" ever used for something other than comparisons?

Yes, als also means "when" for a single event in the past (e.g., Als ich Kind war...), which is a completely different grammatical use from the comparison als covered in this lesson.

What are some useful fixed phrases with "wie"?

So schnell wie möglich (as fast as possible), so bald wie möglich (as soon as possible), genauso...wie (just as...as), and wie immer (as always).
