Ratchanok is the daughter of Winutchai Intanon and Kumpan Suvarsara. She also has a brother. Ratchanok was born in Yasothorn province in the Northeast of Thailand, but moved at the age of 3 months with her parents, who worked at the Banthongyord sweets factory in Bangkhae district of Bangkok. As a child, Ratchanok would run around near the cooking furnaces. Kamala Thongkorn, the owner of the factory, worried that she would be burned by boiling water and hot sugar, so she supported Ratchanok in playing badminton at the factory's badminton courts. She started playing when she was six years old, and won her first championship at the age of seven.
Ratchanok used her prize money and endorsement fees to support her parents and brother. Her father opened a food shop with her help. "I wanted to be a national player like my older friends and play for the country, because that was the only way I could help my parents to improve our status and leave poverty" she said.
