That's true. The evidence is that you can catch tiny waves lying flat on your board that would be impossible to ride standing.
I'm 6'2 and 70kg (not sure of the lbs conversion). I learnt on a 7'8 mini mal, and now ride a 6'6 squash tail, or a 6'0 vintage thruster.
My 6'6 is a fairly narrow board, and is about prefect for my weight.
My 6'0 is much wider and thicker and floats me better while paddling but it is much harder for me to catch waves on.
If you're stepping down, borrow a mate's board that's around the size you think you want, and see how it feels. Also, don't make the mistake of going too short, especially since you're tall!
