Debate break calculator and bracket predictor

Break it estimates how many entries advance to elimination rounds for a tournament size, and Seed it builds the most probable bracket from Tabroom preliminary results.

How it works

Enter tournament size. Give Break it the number of entries and prelim rounds.
Read the estimate. See how many entries are likely to advance and which records are likely to clear.
Predict the bracket. When prelims finish, Seed it turns complete Tabroom results into a probable elimination bracket.
Plan your path. Preview likely elimination matchups before the official bracket is posted.

How many teams break?

Break size depends on the tournament and its rules, so the official number is always the one your tournament announces. Break it gives a fast estimate so you know what record you are aiming for.

Probable bracket

Seed it estimates seeding from complete prelim results, so teams can prepare for likely first-round elimination opponents. Treat it as a prediction; the tournament’s bracket is final.
