Wlad is 6’5” - 6’ 5 1/2” range. He is almost identical in height or a tad shorter than AJ. You could see this in the ring, whereas outside of the ring Wlad tends to look taller because he is an obvious lift wearer and loves playing shenanigans with his footwear to mess with his opponents. He looked almost as tall as Fury in some of the pre-fight meetings yet a good 2” or more shorter in the ring. Of the notable big guys, AJ is probably the closest to his listed height. Deontay is a good 6’6” but not 6’7”. Fury is MAYBE 6’ 7 1/2”. Wlad looked over 6’6” relative to his opponents through a combination of dodgy footwear prior to fights, his excellent physique, and opponents whose official heights were even more inflated than his.
