From how high could you jump if you had a perfect roll at the end? You roll to absorb the impact.

This is the roll I mean:

 

He puts all his weight on his ankles first though. So whatever your ankles can take without breaking.

As a side note it is much safer to fall onto your back or front and roll as that maximises the surface area and reduces the risk of you breaking an ankle or hand.

The point of this technique is to absorb most of the impact by rolling which allows you to jump from higher heights without breaking your ancles. So the strength of your ancles is important but it's not the limiting factor.

In order to roll, you need momentum along the x-axis...you can't jump straight down.

Might not be optimum, but if you have some angle and drop straight down you can develop some momentum along the x axis before going into the roll...whether it is adequate depends on the height and technique
