Summary
The ICC introduced maximum bat dimensions in 2017 — maximum 108mm wide, 67mm deep, and 40mm edge thickness — to prevent bats from getting too big.
Full Explanation
In October 2017, the ICC introduced limits on bat dimensions for the first time in cricket history. This came after years of concern that modern bats, made with better willow and larger profiles, were giving batsmen an unfair advantage.
The new regulations set maximum dimensions: - Width: 108mm (unchanged from existing law) - Depth: 67mm (new limit) - Edge thickness: 40mm (new limit)
Before these regulations, there was no limit on bat depth or edge thickness. Manufacturers had been making bats progressively thicker and heavier, with larger sweet spots. Matthew Hayden's Mongoose bat (short handle, long blade) and various 'jumbo' bats highlighted the arms race.
Umpires now carry bat gauges to measure bats if they suspect a violation. Any bat that exceeds the dimensions is not permitted in the match.
Key Points
- •Maximum width: 108mm, depth: 67mm, edge: 40mm
- •Introduced October 2017
- •Response to bats getting progressively bigger
- •Umpires carry bat gauges to check dimensions
- •Matthew Hayden's Mongoose bat helped trigger the debate
Notable Controversies
- •Debate about whether regulations went far enough
