How many players are in a standard Fortnite battle royale match?

How to get close to this number

The genre name is the clue. Battle royale is built around a last-one-standing structure that needs enough players to feel chaotic and few enough that the server can simulate them all. The format settled on a round hundred across every game that adopted it, which is a design convention rather than a technical limit.

The arithmetic in the explanation is what makes the format interesting: ninety-nine of every hundred players lose, and come straight back. A game where the overwhelming majority of sessions end in defeat should be intolerable, and it is not — because the twenty-minute match structure makes each loss cheap and each near-win memorable.

That is a genuinely clever bit of design worth naming. Traditional competitive games pair you against one opponent and you lose half the time; this format has you lose almost always while feeling like you nearly won, which produces far more engagement per unit of actual success. The player count is what makes that arithmetic work.
