How strictly enforced are water slide height requirements?

First cruise we took our son on 6 years ago he was a hair under 42 inches. They let him ride the first day, and stopped him On other days. What I found at least on fantasy class ships the line to measure is at least an inch over 42 inches. My son was so close to 42 had the sign been correct he would’ve been fine.

 

Fast forward a few years and we are cruising with my son and daughter.  My daughter was 42.5 inches verified at the doctors office a few weeks before the cruise. First time in line they tried to keep her off the slide. Dad was prepared I had a tape measure. Proved her height and never had problems that cruise

Good to know. I thought both of the bigger slides were 42 inches. Is this not the case? If not, do you remember what the requirement was?

 

I may have misspoken. I take pictures of almost everything as I make albums of all my trips and my kids love picture of signs and memorable stuff. I looked at both the horizon and the magic bit could not find the height requirements. I may have mixed up with the horizon and the tube slide as it may allow a lower height requirement. 

 

If  I somehow find a picture I will post.
