A woman in the age of 19-21 has already been reached at the max high.
Very rare for a woman to grow taller at the age of 22-24 but for the age of 30 the probabilities are one in one thousand or better to say it's zero....
The answer to your question is NO a woman cannot grow taller in her 30s.
A woman may appear to be taller because of wearing high heeled shoes or platforms or wearing some types to clothes to give the appearance of height.
We stop growing height wise when we reach maturing at the age of around 20-21. Some people stop growing taller earlier. This is to do with the growth hormone levels in our body and down to genetics.
As we age and stop growing height wise, we do put weight on and grow sideways. As we age the cartilage in between the joints starts to shrink and you will find older people are much shorter than when they were young.
