14cm above max height but at a push you can get 15cm (I've been using it 1cm past max height to give 15cm). Maybe that's naughty but a wiser engineer than myself (me not being an engineer) said as long as the post is inserted 1 1/2 times the diameter in you're okay, providing the frame can take it. The frame is still the same shape.
