>>63185499Taking measurements off her official L2D design document from Kuroboshi, which shows both the front and the back at ~600px tall. Her platforms from the front are 30px, which is 5% of 157cm, or 7.8cm. Her platforms from the back (heels) are 55px, about 9% of 157cm, or 14.4cm.
So actually I was wrong, the heels are even bigger.
