According to Celebrity Heights Priscilla Chan is 5 ft 5 in or 165 cm. This would make her 4 in shorter than her new husband, Mark Zuckerberg, who is 5 ft 9 in or 175 cm. Born in 1985, she is just under a year younger than him.

Priscilla is the daughter of Denis and Yvonne Chan, who are owners of a Chinese restaurant in Boston. She has two sisters, Michelle and Elaine. At this time not much is known about her family; she doesn't seem to be very anxious to be in the limelight but rather to further her husband's career. She certainly does have her own career - she studied medicine and is planning to be a pediatrician - but she isn't using her new fame to promote it.
