About this converter
Oshi no Ko publishes official heights on the anime site and in profile books. Ai Hoshino stands 151 cm, Kana Arima 150, Ruby Hoshino 158, Akane Kurokawa 163, Aqua Hoshino 172 and Hikaru Kamiki 178. The spread is deliberate. Idols cluster short while the two men linked to Ai tower over them. This table keeps the six confirmed figures with their profile sources.
How to use it
Pick two entries and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try Aqua against Ai to see the 21 cm gap. Switch to feet and inches for a familiar reading.
No official heights exist for Mem-cho, Miyako Saitou, Ichigo Saitou, Frill Shiranui or Pieyon, so they are left out. Ruby grows during the story and 158 is her high school value. Aqua at 172 is his teen value. Anime profiles and manga fanbooks agree on these six, and later reprints repeat them. Akane towers over Kana by 13 cm, a gap the stage scenes make plain. Hikaru clears Ai by 27 cm, the widest pair in the table. Ruby at 158 sits between the two.
FAQ

172 cm as a teen. He stands 9 cm over Akane and a full 21 cm over Ai.
Where do these heights come from?
The anime official site and the manga profile books. Both repeat the same six figures used here.
Why are Mem-cho and Pieyon missing?
They were left out because no official height exists for them. The notes name the gap instead of guessing.
