1. Aussi que – Used with adjectives and adverbs
Use aussi que when you’re comparing how something is. In other words, when your comparison involves an adjective (a quality) or an adverb (a manner).

- Ce livre est aussi intéressant que le film.
- This book is as interesting as the movie.
- Il conduit aussi vite que son frère.

2. Autant que – Used with verbs and nouns (quantities)
Use autant que when you’re comparing how much or how many, in other words, quantities or amounts. It can come before a verb or a noun.
Structure:
autant + verb/noun + que
Examples:
- Il travaille autant que moi.
- He works as much as I do.
- J’ai autant d’amis que toi.
- I have as many friends as you.
- Elle mange autant que son frère.

3. Easy way to remember
| Type of comparison | Use | Example |
| Qualities (adjectives/adverbs) | aussi que | Il est aussi grand que moi. |
| Quantities (verbs/nouns) | autant que | Il mange autant que moi. |
If it answers “how is it?” – Aussi que
If it answers “how much/many?” – Autant que
