This study was undertaken to find out the suitable breaking wave formulas for computing breaker depth, and corresponding orbital to phase velocity ratio and breaker height converted with linear wave theory. A large amount and wide range of published laboratory data (695 cases collected from 26 sources of published laboratory data) were used to examine and develop the breaker formulas. Examination of some existing formulas indicates that none of them can be used for a wide range of experimental conditions. New breaker formulas were developed based on the re-analysis of the existing formulas. Overall, the new formulas give good predictions over a wide range of experimental conditions.
