What's the steepest ladder you would personally be willing to climb? The shallowest?

Personally, the steepest ladder I would be willing to climb would be a ladder with 2 meters long, that's it, because I don't like hights.

On the other hand, the shallowest ladder would be the nearest to the ground level possible, because, as I said before, I don't like being to far away from ground level.
