Tall. Really, really tall...

That's it really. He's tall.
Very tall...

There is a doorway at mum and dad's house where everyone's height is written.
I'm pretty much the shortest, at just over 5'2". Both of my daughters are taller than I am, as are my nieces. Chris (my nephew) is pretty tall, as is my eldest daughter's boyfriend.
So there is this scale - Lynne at the bottom, Beth's Mark at the top.
And then there's my nieces tutor. He doesn't even fit on the door frame.
Here he is, next to Dad. Dad is around 5'7", I think. Not hugely tall, but on an average scale.
