Draft only. A coach must review experience, safety, consent, singletons and uneven sizes before any bout. This weight-first method respects your maximums; it cannot guarantee equal groups.
No account needed. Entries stay in this browser unless you choose to share or print.
Quick answer
Draft Madison wrestling groups by pasting a roster with names, weights and ages and setting maximum weight spread, age gap and group size. The calculator sorts wrestlers by weight and places each into the first group that fits every selected limit. It never relaxes your limits to fill a group. Singletons and uneven group sizes can remain and require a coach’s review. The output is a grouping draft, not a safety clearance, official bracket or live tournament.
How should I paste a Madison roster?
Use one wrestler per line in the form name, weight, age. Weights are pounds and ages are whole years. The parser requires exactly three comma-separated fields, so replace a comma inside a name with a space. Up to 256 rows can be grouped at once. The example roster shows a small practice-sized field; replace it with your entries to get your own output. Missing ages or invalid weights are reported by row number so they can be corrected without silently dropping a wrestler.
How are weight spread and age gap enforced?
The spread is the heaviest weight minus the lightest weight across the entire group. Likewise, age gap compares the oldest and youngest members. These are group-wide limits, not merely differences between neighboring wrestlers. Sorting by weight makes the method repeatable, then each entrant goes into the first existing group that satisfies those two limits and has space. Otherwise, a new group starts. Maximum group size can be set from two to eight, allowing small round-robin drafts as well as larger brackets.
Why can a draft contain singletons or uneven groups?
Some rosters cannot be evenly partitioned within the selected constraints. The tool preserves those constraints and flags a one-person group for review rather than placing a substantially different athlete into it. It does not evaluate experience, skill, consent, medical status or coaching judgments. Review every group before arranging matches, especially at the edges of the roster. Adjusting a limit is a deliberate host decision, and this calculator does not recommend a universal spread or age gap. After review, use the round-robin tool to create pairings for each suitable group.
Frequently asked questions
Is this an official Madison weight system rule?
No. Madison events set their own grouping policies. This is a configurable planning method with explicit maximums; it does not claim a universal governing-body standard.
Does the calculator guarantee balanced group sizes?
No. The weight-first grouping respects your limits, but the distribution of a roster can leave uneven groups or singletons. The output shows every entrant so a coach can review and revise the draft.
Are pasted names and weights uploaded?
No. Grouping runs in the browser without an API request. Copying a snapshot link with entries is an explicit sharing action, and anyone receiving that link can read the roster.
