The weight miss registry

A weight miss is reported as a number of pounds. A pound means one thing at heavyweight and something else at flyweight, and the fine that follows has no published scale at all. This page keeps the record in a form that can be compared: the overage as a percentage of the contracted limit, the penalty, and what happened to the bout.

What the record shows

The typical miss is small. The median overage is under 2 percent of the limit. Of the cases with a recorded weight, eleven are under 1 percent, twenty-six sit between 1 and 3 percent, and twelve are above 3 percent.

The fine is not proportional. Half a pound has cost 20 percent of a purse. One pound has cost 30. Five pounds has cost 25. Misses above three percent of the limit were still fined 25 or 30 percent, like the small ones. The two exceptions are 35 percent for a five-pound miss and 50 percent for an eight-pound one. The scale sits with the promotion and the commission, and it is published nowhere.

The bout usually goes ahead. Most misses end in a catchweight. Cancellation is rare and, in the verified record, it arrives either with a very large miss or when a fighter does not make the scale at all.

Some divisions carry more of it. Middleweight and flyweight account for the largest share of verified misses, which is the pattern you would expect at the two ends of the problem: the division where fighters arrive from above, and the division where there is nothing left to take off.

A miss is rarely a first offence. Where a fighter appears twice in this table, or is recorded as a repeat offender in the source, it is noted in the row.

The table

What happens after the scale

A second table on this page uses the only public data on how much weight comes back. The California commission weighs fighters again on the day of the event and publishes the figures.

Across the verified cards, the median fighter regains about 13 percent of body mass between the weigh-in and the fight. The commission treats 10 percent as the point at which it recommends a move up a division and 15 percent as the point at which it will consider refusing the bout. In the record here, a clear majority cross the first line and a large minority cross the second. The whole record, by weight and by card, is analysed in how much weight UFC fighters gain after the weigh-in.

The rehydration page explains what those numbers mean physiologically, and what happens if a fighter misses weight covers the rules behind the penalties.

Method

• Only verified cases are listed. A case enters the table when the weight appears in official weigh-in results or in a commission document, and the consequence is reported by the promotion, the commission or a named outlet. A few rows are marked in the notes as still to confirm, where the figure comes from a secondary report. They are shown rather than hidden, with the caveat attached.
• The overage is calculated against the contracted limit, including the one-pound allowance where the bout is non-title, so a featherweight non-title miss is measured against 146 rather than 145.
• Percentages are rounded to two decimals. Where a source gives a weight but not a fine, the penalty column says so rather than guessing.
• Fighters who missed on a first attempt and made the limit within the extra hour are not listed as misses.
• The fight-night table carries only figures published by a commission. It is not an estimate.
• Corrections are welcome. The source for every row is in the last column.
• The data on this page is published under a Creative Commons Attribution 4.0 licence. You may reuse it, including commercially, as long as you credit Foka Elite and link to this page.
