He looked around 5'10'' in The Devil's Double.

He is not very tall, but he does have good proportions. I believe he is 5 ft 9.5 in.

Actually, I found these earlier (2006) pictures of him with a 5'7" James McAvoy:

It's strange, because he looks taller, these days. Is he a lift wearer? It's not possible that he grew, is it? Even given that he's closer to the camera in those two shots, you'd expect him to look significantly taller than McAvoy being almost 5'10" , and all. They are also all in casual wear in the picture, so I can't imagine their footwear being significantly different. But, even if it was, there is no way Dominic should be looking exactly the same height (and in one of the shots, shorter) as McAvoy.

This looks about right, though, I've noticed he can look much shorter due to his incredibly narrow shoulders and waist.
