TUIDE’s seven members are currently 15 to 19 years old, with Seohee the oldest and Yi Hani the youngest. The group’s TUIDE members' ages are unusually clustered because three members are 18 and another three are 15 as of September 27, 2026.
The exact TUIDE members' age order is Seohee, Seoyeon, Elena, Jia, Saki, Seah, then Yi Hani. Their birth dates make the ordering clear even where two or three members share the same current age, which is why a simple 19, 18, 18, 18, 15, 15, 15 sequence misses some useful detail.
TUIDE’s seven-member ABD lineup consists of Seohee, Seoyeon, Elena, Jia, Saki, Seah, and Yi Hani. Their ages were not central to TUIDE’s private debut process, which kept the selection process away from public rankings and elimination episodes.
For TUIDE members' ages and birthdays, the exact dates matter more than the age number alone. Seoyeon is older than Elena by a little over a month, Elena is older than Jia by four months, and Seah is only three days older than Yi Hani. Jia also turned 18 on August 22, just two days before TUIDE debuted on August 24, 2026.
The TUIDE oldest member age is therefore 19, belonging to Seohee. Seohee’s age in TUIDE can briefly make the group look more spread out than it is because the next three members are all 2008-born. She is almost two years older than Seoyeon but nearly four years older than Saki.
The TUIDE youngest member is 15. Yi Hani holds the maknae spot because her January 7, 2011 birthday comes three days after Seah’s, not because she is the only 15-year-old. For anyone checking the TUIDE members' maknae age, Saki and Seah are also 15 right now, but both are older by birth date.
The debut-date snapshot is almost unusually tidy. Jia had turned 18 on August 22, two days before the August 24 debut, while the next birthdays belong to Saki and Seohee in October. TUIDE therefore debuted with the same 19, 18, 18, 18, 15, 15, 15 age pattern seen on September 27. The actual gap from Seohee’s birth date to Yi Hani’s is about four years and three months, even though their birth years run from 2006 through 2011.
Saki’s age in TUIDE is 15 until October 9, 2026. Two days later, Seohee turns 20 on October 11. Anyone revisiting the TUIDE members' ages, oldest to youngest, after those dates will see the numerical range change from 15 to 19 to 15 to 20 without any change to the actual birth order.
TUIDE members' age and nationality are separate pieces of the profile. Seohee, Seoyeon, and Seah are Korean, Elena is American, Saki is Japanese, Jia has a Korean-American background, and Yi Hani has a Korean-British background in recent profile coverage. The group itself remains an ABD artist under HYBE regardless of those individual backgrounds.
The same caution applies when trying to infer authority from Seohee being the eldest. Creative decisions sit within the group’s wider production structure, including music, concept, and performance oversight led by executive producer Han Sung Soo. Being older does not automatically establish who controls a song, choreography, or visual direction.
The useful snapshot for TUIDE members' ages and names on September 27 is simple. Seohee is 19, Seoyeon is 18, Elena is 18, Jia is 18, Saki is 15, Seah is 15, and Yi Hani is 15. Since Saki and Seohee both have October birthdays, this particular age snapshot has a short shelf life, even though the oldest-to-youngest order stays fixed.

Exact birthdays settle the age order
Seohee was born October 11, 2006, making her 19. Seoyeon was born March 4, 2008, Elena on April 11, 2008, and Jia on August 22, 2008, so all three are 18. Saki was born October 9, 2010, while Seah and Yi Hani were born January 4 and January 7, 2011. All three are currently 15.For TUIDE members' ages and birthdays, the exact dates matter more than the age number alone.

The age groups split into three clear lines
A practical way to read TUIDE members' age 2026 data is by birth year. Seohee forms the 2006 line, Seoyeon, Elena, and Jia make up the 2008 line, Saki represents 2010, and Seah and Yi Hani form the 2011 line. It is cleaner than repeatedly recalculating seven ages whenever a birthday passes.Saki’s age in TUIDE is 15 until October 9, 2026. Two days later, Seohee turns 20 on October 11. Anyone revisiting the TUIDE members' ages, oldest to youngest, after those dates will see the numerical range change from 15 to 19 to 15 to 20 without any change to the actual birth order.
TUIDE members' age and nationality are separate pieces of the profile.

The group itself remains an ABD artist under HYBE regardless of those individual backgrounds.
Age does not determine member positions
TUIDE members' age and position should not be treated as the same hierarchy. Yi Hani’s youngest-member status is an age fact, while vocalist, dancer, center, leadership, and other performance responsibilities require separate confirmation. Profile databases do not even agree consistently on every position, so birth order is the safer thing to state from dates alone.The same caution applies when trying to infer authority from Seohee being the eldest. Creative decisions sit within the group’s wider production structure, including music, concept, and performance oversight led by executive producer Han Sung Soo. Being older does not automatically establish who controls a song, choreography, or visual direction.
