(119951) 2002 KX14 is a large classical TNO with limited previous observations and unresolved questions regarding its physical properties. Five stellar occultations by 2002 KX14 were observed from 2020 to 2023, involving multiple telescopes across different locations in Europe and the Americas. The five occultations resulted in 15 positive chords, accurately measuring the 2002 KX14's shape and size. The projected ellipse has semi-major and semi-minor axes of 241.0±7.2 km and 157.1±5.2 km, respectively, corresponding to an average area-equivalent diameter of 389.2±8.7 km. The geometric albedo was estimated at 11.9±0.7%.
