He´s not this tall, I´d say 1.87m barefoot.

I think 6ft2.5 or 6ft2.75 may be closer

I think, Tuc Watkin's heights are:

Morning (out of bed)= 6'2.75" (1.90 m)
After 1,5-3 hrs= 6'2.4" (1.89 m)
After 5-10 hrs= 6'2" (1.88 m)

I suppose he could be a solid 1.90 m in the early morning, but in the afternoon he's around 1.88 m.
In the mummy he seems 0,6in/1,5cm shorter than Brendan Fraser, who i'm sure is a solid 6'3.15" (1.91 m) in the morning and 1.89 m in the afternoon!

hmmm not too sure about 6"3

On DH he looks more like 6"1.5/6"2
