It maybe more of an issue of torso vs leg length rather that your height.
Take a look at these articles:

10 Tips for Flawless Squattin'
"1. Dolicomorph (relatively long limbed individuals)
Shoulder width: 23% or less of height
Leg length: 55% or more of height
Arm length: 45% of height
- Brachiomorphs (relatively short limbed individuals)
Shoulder width: 25% or more of height
Leg length: 50-53% or more of height
Arm length: 40-43% of height
- Mesomorphs (balanced individuals)
Shoulder width: 24-25% of height
Leg length: 53-55% or more of height
Arm length: 43-45% of height
Note that in this classification (Tkachenko, 1979) mesomorph is not the same as the "mesomorph" type we normally use; it refers to body structure not muscularity"
I personally struggled alot until I realized my leg length was 65% of my height. Hope this helps.
