Is it Longer than normal?

Question

No not anything like that, my armspan

I'm 5'6.5" and my armspan is 3 inches longer than that, is that normal?

Could it mean i still have a few inches to grow?

Answer 1

Ape index is an informal measure of one's armspan relative to height. Among some rock climbers it is seen as desirable to have an arm span that exceeds one's height.[1] It is calculated either by subtraction (armspan − height) in which case the desired result is a positive ape index, or by division (armspan ÷ height) in which case one desires a ratio greater than 1.

Despite the assumed desirability of a larger value, several scientific studies failed to demonstrate a correlation between the ape index and rock climbing ability. [2][3]

Answer 2

Not necessarily because its normal for arm span to be slightly longer than height as u will see with many basketball players. My arm span is 6'7.5" while i am 6'2" tall.
