How Should Organizers Handle Byes When a Bracket Is Not a Power of Two?
Few tournaments have exactly 8 or 16 teams. Here is how to place byes so an odd-sized bracket stays fair.
When your field does not equal a power of two, byes fill the gap so the rounds line up, letting some teams advance a round without playing. Award those byes to the highest seeds by convention, spread them evenly so neither half of the bracket is lighter, and let the structure place them automatically.
Why byes exist
Brackets are built on powers of two, 8, 16, 32. When your field does not match, byes fill the gap so the rounds line up cleanly.
A bye simply means a team advances without playing that round because it had no opponent.

Give byes to the top seeds
The fair convention is to award byes to the highest seeds. It rewards their standing with a lighter first round and keeps the structure balanced. Related: Does Reseeding a Bracket After Each Round Really Reward the Top Seeds?

Balance them across the bracket
Byes should be spread so one half of the bracket is not far lighter than the other. Even distribution keeps both sides comparably difficult.
Clustered byes create an unfair easy path on one side.
Let the structure place them for you
Working out byes by hand is error-prone. Having the bracket place them automatically by seed removes the mistakes and the arguments.
The math is fiddly, so let the structure handle it and check the result.
