Pleumjit grew up in a sport-loving family in Angthong (a province about 100km. north of Bangkok), having an elder brother. Her parents are civil servants. Before she started playing volleyball, she was into table tennis. She switched to volleyball following her father's advice that volleyball was more fun and more likely to become popular. Afterwards, a volleyball coach of Bodindecha (Sing Singhaseni) School in Bangkok was so impressed by her playing that he brought her to the school during her high-school level. At first, she did not play as a middle blocker but an outside hitter.[3]
Pleumjit was first capped for the national junior team in 2000. A year later, she was chosen to join the national team when she was 17 years old. and She went to play professional volleyball overseas for the first time in China for a month when she was 19 years old.[citation needed]
