Key Fact: Ski length for athletes with BMI below 21.0 is reduced by 0.125 m per 0.5 unit below threshold.

Maximum length: 146% of the athlete's body height (Article 222.1, ICR). Athletes with a Body Mass Index (BMI) below 21.0 receive a ski length reduction of 0.125 m for each 0.5 BMI unit below the threshold.; Width: 105–118 mm (4.1–4.6 in) at the binding area. Tip width may differ but must follow t...

Material thickness: Maximum 6 mm (0.24 in) at any measured point.; Air permeability: Minimum 40 l/m²/s (±5 l/m²/s tolerance). Measured at multiple points during random equipment checks.; Fit tolerance: Maximum 2 cm (0.79 in) from body contour at any measured point when standing u...

Helmet: FIS-approved helmet mandatory. Smooth surface with no aerodynamic modifications, wings, or extensions. Visor or goggles permitted but must not extend beyond helmet profile.; Boots: Maximum boot height 30 cm (11.8 in) from sole. Must support the forward lean angle required by the binding s...

Introduced to combat dangerous weight loss practices, the BMI rule links maximum ski length to body mass. Athletes must weigh in before competition.

All competition hills must be homologated (certified) by FIS and are classified by their Hill Size (HS), the maximum safe landing distance: Small Hill: HS 20–49 m (training and youth competitions); Medium Hill: HS 50–84 m (national-level events); Normal Hill: HS 85–109 m (Olympic Normal Hill typi...

Competition takes place on homologated FIS hills classified by Hill Size (HS).

In-run (approach): Straight track of 80–120 m (262–394 ft) with a gradient of 33–38 degrees. Surface is prepared ice track in a profile-milled groove.; Takeoff table: Curved transition from in-run slope to the lip. Table angle typically 10–11 degrees on Normal Hill, 10–11.5 degrees on Large Hill....

Competition hills are equipped with multiple wind sensors at standardised positions along the flight path. Sensors measure wind speed and direction at the takeoff, mid-flight, and landing zones.

Individual events: Each nation may enter up to 4 athletes per event at the Olympics. World Cup allows broader entry based on national ranking quotas.; Team events: Teams of 4 jumpers. Each member jumps twice (two rounds). The Mixed Team event uses 2 men and 2 women.; Starting order: Determined by...
