I remember it like this:
Finals - 1 match - 2 participants
Semifinals - 2 matches - 4 participants
Quarterfinals - 4 matches - 8 participants
Round of 16 - 8 matches - 16 participants
Round of 32 - 16 matches - **32 participants **
In every round, half of the participants are eliminated and the other half moves on.

But that is what it’s called. E.g., the FIFA World Cup 2023 brackets.
Round of 8 doesn’t follow the convention, either, because that would be ‘eighth final’.
