Guidelines & measurement rules

A record must be measured by a single, objective value — time, distance, weight, quantity or count — that another person could attempt to beat.

Use certified scales, tapes, timers or GPS devices. Show the instrument and its calibration on camera before and after the attempt.

At least two independent adult witnesses with no family or financial tie to the applicant must observe the full attempt and sign a statement.

Attempts that endanger people or animals, break the law, or harm the environment are not accepted.
