Height of future child?

[RichZygoRodger]

I’m about 6’2 to 6’3, based on the way things are going my future wife will be around 5’5 to 5’6. If my future son or daughter were fed good diets, had great postures, and spent lots of time outside, what might their respective heights be? I feel like those 3 things have a huge effect and will help boost more than just genetics right. I can’t really trust online calculators as they don’t factor these things in.
