It is not common to use the phrase "My height is" when indicating your height in inches, as it can be ambiguous and potentially confusing. It is more common to say "I am" or "I'm" followed by the height measurement in feet and inches. For example, "I'm 5' 8''".
However, if you want to be specific and use pounds to indicate your weight, you could say something like "I weigh 150 pounds and I'm 5' 8'' tall." This way, it's clear that you are talking about your weight and your height separately.
