Top Cut Calculator
A free top cut calculator for Swiss tournaments: enter your field size to get the standard single-elimination cut - Top 4, Top 8, or Top 16 - along with the playoff seeding, the number of knockout rounds, and the total length of the event.
Most competitive Swiss events cut to a Top 8 single-elimination playoff - a Top 4 for small or team events, a Top 16 for very large fields. A Top 8 plays 3 knockout rounds (quarterfinals, semifinals, final); a Top 4 plays 2; a Top 16 plays 4. Enter your player count below to see the cut, the playoff seeding, and the total event length.

For 32 players, the usual cut is a Top 8 single-elimination playoff after 5 Swiss rounds. The Top 8 takes 3 knockout rounds (quarterfinals, semifinals, final), for a 8-round event in total. Top 8 is the standard competitive cut.
Top 8 playoff seeding (first round)
Seed the top 8 finishers by their final Swiss standing, then bracket them so the No. 1 seed meets the lowest survivor and the top seeds only meet in the later rounds.
Typical top cut by field size
| Players | Top cut | Playoff rounds |

| 5-8 | Top 4 | 2 rounds |
| 9-32 | Top 8 | 3 rounds |
| 33-226 | Top 8 | 3 rounds |
| 227+ | Top 16 | 4 rounds |
A cut of C players always needs ceil(log2 C) knockout rounds. Ready to run the event? Generate the Swiss bracket, or work out the Swiss round count with the Swiss rounds calculator.
How the top cut works
A Swiss tournament runs a fixed number of rounds - ceil(log2(N)) at a minimum - and nobody is eliminated during them. The top cut is the single-elimination playoff bolted on the end: the highest finishers by final Swiss standing advance to a knockout bracket that decides the champion.
The cut size is a convention, not a formula. Top 8 is the long-standing competitive default; small events run a Top 4 or skip the cut entirely and rank straight off the Swiss standings, while very large events use a Top 16. Once you know the cut size C, the playoff always takes ceil(log2(C)) rounds - 2 for a Top 4, 3 for a Top 8, 4 for a Top 16 - so the total event is the Swiss rounds plus those playoff rounds.
Top cut by game
Magic: The Gathering
The Magic Tournament Rules run a Top 8 single-elimination playoff for most events, and a Top 4 for small or team events. The Top 8 is seeded 1v8, 4v5, 3v6, 2v7 off the Swiss standings.
Pokemon TCG
Play! Pokemon events run a single-elimination top cut after Swiss, with the highest seeds taking byes when the cut is not a power of two. The handbook caps an asymmetrical top cut at 16 competitors.
Esports Swiss stages
CS2 and Valorant Swiss stages advance a fixed number of teams (often 8) on record to a single-elimination playoff - the same top-cut idea, sized to the event rather than the field.
Sources: the Magic: The Gathering Tournament Rules (Appendix E, effective February 27, 2026: Top 8 from 17 players up, Top 4 for 9 to 16 players) and the Play! Pokémon TCG Tournament Handbook (single-elimination top cut, byes for the highest seeds, cap of 16). The organizer sets the final cut size.
Top Cut FAQ
What is a top cut?
The top cut is the single-elimination playoff run after the Swiss rounds. Once every entrant has played the fixed number of Swiss rounds, the highest-placing players by final standing advance to a knockout bracket that decides the champion. "Top 8" means the best 8 finishers make that playoff.
How big should the top cut be?
Top 8 is the standard single-elimination cut for competitive Swiss events - the Magic: The Gathering Tournament Rules use a Top 8 for most events and a Top 4 for small or team events. Small local events often run a Top 4 (or no cut at all), and large events use a Top 16; the Play! Pokemon handbook caps an asymmetrical top cut at 16 competitors. The calculator suggests a typical cut for your field size, but the organizer sets the final number.
How many rounds does the top cut take?
A cut of C players needs ceil(log2(C)) single-elimination rounds: a Top 4 is 2 rounds (semifinals and final), a Top 8 is 3 rounds (quarterfinals, semifinals, final), and a Top 16 is 4 rounds. Add these to your Swiss rounds for the total event length - for example a 32-player Top 8 is 5 Swiss rounds plus 3 playoff rounds, 8 rounds in all.
How is the top cut playoff seeded?
Seed the qualifiers by their final Swiss standing, then bracket them as a standard single-elimination draw so the top seeds only meet late. A Top 8 pairs 1v8, 4v5, 3v6, 2v7; a Top 4 pairs 1v4, 2v3. The higher Swiss seed usually gets a choice (play or draw priority, first turn, or home side) in each playoff match.
What record do I need to make top cut?
It depends on the field size and tiebreakers, so there is no single guaranteed number. As a guideline for a Top 8: an undefeated (X-0) or one-loss (X-1) record almost always advances, two losses (X-2) is usually the bubble that tiebreaks (Buchholz or opponents’ win percentage) decide, and three or more losses rarely makes a standard Top 8. Larger fields and more rounds tighten the bubble.
