The Hill-Size defines the size of a jumping facility. Normal-hill or large-hill, as well as K 90 or K 120 are only classifications but don’t indicate the actual size of the hill. It was introduced in the year 2004.
It is calculated regarding the technical data of the hill, for example radius, angle of inclination and record-distance. The hill size is the distance between the end of the take-off table and that point in the landing area where the hill still has a gradient of 32°.
Small hills: HS up to 49 m
Medium hills: HS 50 m to 84 m
Normal hills: HS 85 m to 109 m
Large hills: HS 110 m and larger
Flying hills: HS 185 m and larger
