Excuse me for the irrelevance

In the show, FL always says that someone tall and sophisticated like Mal's ex gf is more suitable for him. Now, I have always thought Abigail is petite but she is much taller than Richa. How tall could both the actresses probably be?? 

I think like Darsh mentioned in the episode yesterday, Richa probably is 5.4"

Abigail may be around the same or just about a couple of inches taller?
