Term
Amplitude
The size or height of an aerial performance under the applicable judging convention.
GLOSSARY · Competition & formats
In halfpipe, slopestyle and big air judging, amplitude is how big the tricks are — height out of the pipe, distance or air time — weighed against how well they are done.
Context and distinction
Amplitude is size; execution is quality. Judging systems balance them with difficulty, variety and progression.
