March Madness is entering a new era. Beginning with the 2027 NCAA Division I Men’s and Women’s Basketball Championships, both tournaments expand from 68 to 76 teams. The familiar 64-team First Round remains, but a larger Opening Round now determines which teams advance into that traditional bracket.
That makes older explainers built around a 68-team field outdated for 2027. Here is the current structure, based on the NCAA’s published championship and selection guidance.
How many teams make March Madness in 2027?
Both the men’s and women’s Division I tournaments have 76 teams. The NCAA says each field consists of 32 automatic qualifiers and 44 at-large teams.
Automatic qualifiers earn their places through their conferences. The remaining at-large teams are selected by the respective NCAA basketball committees using metrics and broader team evaluation.
What is the new March Madness Opening Round?
The expansion adds a 12-game Opening Round. Those games reduce the field from 76 teams to the familiar 64-team bracket.
Once the Opening Round is complete, the tournament returns to the traditional flow: 32 First Round games reduce the field to 32, followed by the Second Round, regional semifinals and regional finals, the Final Four and the national championship game.
For the 2027 men’s tournament, Dayton and Wichita will host the Opening Round. Each city is scheduled to host three games on Tuesday and three on Wednesday after Selection Sunday, producing the 12 Opening Round games across the two sites.
How are teams selected?
Selection has two main routes. Conference automatic qualifiers enter the tournament through their league’s qualifying path, while the selection committee chooses the at-large field. For 2027, the NCAA’s current March Madness selection guidance lists 32 automatic qualifiers and 44 at-large selections for both tournaments.
Selection is not the same thing as seeding. After choosing the at-large teams, the committee ranks and seeds the full field and then places teams into the bracket according to championship principles and procedures.
What happens after the Opening Round?
After 12 Opening Round winners are determined, 64 teams remain. From there, March Madness follows the bracket rhythm most fans already know:
- First Round: 64 teams, 32 games.
- Second Round: 32 teams compete for Sweet 16 places.
- Sweet 16: the regional semifinals.
- Elite Eight: the regional finals.
- Final Four: four regional survivors play the national semifinals.
- National championship: the two semifinal winners play for the title.
It remains a single-elimination championship: one loss ends a team’s run.
Why did the tournament expand?
The NCAA announced the move in May 2026, adding eight teams to each championship. The stated goals include increasing championship opportunities for student-athletes and expanding financial support connected to tournament participation while preserving the traditional 64-team First Round.
The change matters for fans because older references to the “First Four” and a 68-team field no longer describe the 2027 championship structure. The NCAA now calls the expanded preliminary stage the March Madness Opening Round.
Are the men’s and women’s formats the same?
At the high level covered here, both 2027 championships use 76-team fields, 12-game Opening Rounds and 64-team First Rounds. Both have 32 automatic qualifiers and 44 at-large teams under current NCAA guidance.
Operational details can still differ between the men’s and women’s championships, including sites, hosting arrangements and specific bracketing procedures. Those details should be checked against the current championship manuals rather than assumed to be identical.
When are the 2027 Final Fours?
The NCAA lists the 2027 Women’s Final Four for April 2 and April 4 in Columbus, Ohio. The 2027 Men’s Final Four is scheduled for April 3 and April 5 at Ford Field in Detroit. Dates and event details should always be rechecked as the championship approaches.
Why the 64-team bracket still matters
The biggest structural insight is that expansion happens before the traditional First Round. The Opening Round creates additional access, but after it finishes the tournament becomes the same 64-team elimination bracket that drives the familiar sequence from the First Round to the Final Four.
