My eyes tell me he's around 5' 8".
I decided to look up some height predictors based on arm span and hand length. I found a few that use one or the other and a study that uses both. I decided to throw Kyler's measurements in to the equation for both arm span and hand length to see what his predicted height is.
Here's the regression formula from the paper I used if anyone wants to check for themselves. The formula is for males and you'll have to convert his combine numbers to cm.
54.399 + (0.606) Arm span + (0.741) Hand

The model predicts he is 178.914 cm tall. That equals 5' 10.4".
They found no statistically significant difference between measured (actual) height and predicted height, so this model does a good job of predicting actual height.
However, the margin of error is +/- 1.87 inches and the study is based on an Indian sub-continent population.
To add to those caveats, Kyler has really short arms and relatively large hands. Arm span is typically a decent indicator of height, or a little longer than the actual height in many athletes. Kyler's wingspan is 5' 9.4".
