Yep, he looks pretty taller than 2.12m in some photos, but as always in these cases, it depends on the person he is photographed with. For instance, on the last photo, where (I guess) he is posing with his volleyball team mates, he does not look so tall, although he is the tallest of all of them.
The post title was changed from 2.17m to 2.12m. The height of 2.12m are that he was registered with the Brazilian national team in 2009 at the age of 19 years, perhaps grown a little and barefoot is a 7 '1 ". Do not say for sure if it exceeds 7 '2 "barefoot, and if with her shoes he is a 7' 3" (for which a barefoot 7'2 "or more) are likely to qualify to be on the list of giants. The current photo look very high and is young so may still be growing.
