Her account, @kaylamanouss, has been associated with more than 1 million followers, while her Instagram presence has helped expand her influence beyond short form video. Famous Birthdays lists her birth date as March 28, 2004, and identifies her as a TikTok creator known for fitness and beauty content.
Search results for Kayla Manousselis show that readers are particularly interested in her age, family background, relationship status, height, ethnicity, career, brand partnerships and net worth. However, several biography websites publish conflicting information, especially about her age calculations, physical measurements and estimated wealth. This article separates information that can be supported from estimates that remain unverified.
Kayla Manousselis Age
Kayla Manousselis was born on March 28, 2004, making her 22 years old in 2026. Her birth date is consistently reported by Famous Birthdays and several biography sources.
Some pages have incorrectly listed her age or zodiac sign. Since March 28 falls under Aries in the Western zodiac system, claims that she is a Capricorn or Gemini are inconsistent with her published birth date.
Her relatively young age is one reason her social media career has attracted attention. She began creating content while still young and has subsequently developed her online presence across multiple platforms.
Kayla Manousselis Bio
Kayla Manousselis is primarily known as a TikTok creator, Instagram personality and fitness focused influencer.
Her content includes:
- Fitness and workout related posts
- Dance videos
- Lip sync content
- Fashion and modeling
- Beauty and lifestyle material
- Sponsored brand content
Famous Birthdays reports that she made her TikTok debut in 2018 with a video using music by rapper Mike Stud. It also identifies her as a creator who has attracted more than 1.2 million followers through fitness and beauty related content.
Her online identity has gradually developed beyond TikTok. Her Linktree profile currently connects followers with fitness resources, brand offers and other social channels, while her Linkme profile identifies her with fitness, training and lifestyle content.
This broader presence is important because Kayla’s career is based on building a personal brand rather than relying on a single social media platform.
Kayla Manousselis Childhood and Family
Public information about Kayla Manousselis’s childhood is limited.
Several biography websites claim that she grew up in the United States and provide names for her parents and siblings. However, these details are not consistently supported by strong primary sources, so they should be treated cautiously.
What is better established is that Kayla was born in the United States and began developing her online presence during her teenage years. Her early TikTok activity eventually developed into a larger creator career.
Famous Birthdays also confirms that she was born in the United States and identifies Matt Karis as part of her publicly reported family life.
Kayla’s relatively private approach to family information means there is still limited reliable material about her parents, siblings and childhood experiences.
Personal Life of Kayla Manousselis
Kayla Manousselis shares parts of her personal life through social media, particularly content related to fitness, fashion, travel and relationships.
She has been publicly linked to Matt Karis, and several biography sources report that the two are in a relationship. Famous Birthdays also lists Matt Karis under her family life information.
Her public profiles suggest that fitness plays a significant role in her daily lifestyle. Her Linkme profile, for example, describes an interest in clean eating and disciplined training.
At the same time, information about her private family life should not be expanded beyond what she or reliable sources have publicly shared.
Kayla Manousselis’s Career
Kayla’s career developed through short form social media, particularly TikTok.
She reportedly joined TikTok in 2018 and began posting dance and lip sync content. Over time, her content expanded toward fitness, fashion, modeling and lifestyle topics. Famous Birthdays notes that one of her popular TikTok videos involved a humorous gym related concept and accumulated more than 7 million views.
This type of viral content helped introduce Kayla to a larger audience.
Her career can broadly be divided into several areas:
- TikTok content creation
- Instagram modeling and lifestyle content
- Fitness content
- Brand partnerships
- Fashion and swimwear promotion
- Digital personal branding
Kayla also appears to have maintained an education and professional profile alongside her social media work. A LinkedIn profile under her name lists San Diego State University from 2022 to 2026.
This provides an additional dimension to her public profile beyond influencer marketing.
What Brands Has She Been Working With?
Kayla Manousselis has been associated with several fitness, fashion and lifestyle brands.
One of the most frequently mentioned collaborations is BOUTINE Los Angeles, a fashion and swimwear company. Famous Birthdays specifically notes that Kayla promotes the clothing line through her social accounts.
Her public Linktree also connects followers with Bloom Nutrition and a FitJeans discount code, showing how her creator profile has developed into a channel for commercial partnerships.
Her Linkme profile additionally lists REDCON1 and other commercial links, although the precise nature and current status of every partnership can change over time.
For an influencer, these partnerships can provide income through sponsored posts, affiliate arrangements, discount codes, ambassador programs and product promotions.

Kayla Manousselis Height and Weight
There is no single authoritative public source confirming Kayla Manousselis’s exact height and weight.
Different online biographies report measurements ranging from approximately 5 feet 3 inches to 5 feet 6 inches and around 54 to 55 kilograms.
Because these figures conflict, it is more accurate to describe them as reported measurements rather than confirmed facts.
| Physical Detail | Commonly Reported Figure |
| Height | Approximately 5’4″ to 5’6″ |
| Weight | Approximately 54 to 55 kg |
| Hair | Blonde or brown in different reports |
| Eyes | Brown or hazel in different reports |
Kayla frequently incorporates fitness into her online content, which has contributed to her public image as a fitness and lifestyle creator.
Kayla Manousselis Net Worth
Kayla Manousselis’s exact net worth in 2026 is not publicly verified.
This is an important distinction because several websites publish precise figures without providing financial records, contracts or other documentation. Current estimates range widely, with some pages suggesting hundreds of thousands of dollars and others claiming figures above $1 million.
Rather than presenting one estimate as fact, her potential income sources can be identified from her public career.
How Kayla Manousselis Makes Money
Her potential revenue streams include:
- Sponsored social media content
- Brand ambassador partnerships
- Affiliate marketing
- Fashion and modeling campaigns
- Fitness related promotions
- Product endorsements
- Social media monetization
Her large TikTok audience and commercial partnerships create opportunities for influencer income. Her public Linktree and Linkme profiles also demonstrate that she uses affiliate and promotional links.
However, follower counts alone cannot establish someone’s net worth. A reliable net-worth calculation would require information about income, taxes, expenses, investments, assets and liabilities.
For that reason, Kayla Manousselis’s net worth should be described as unconfirmed rather than a fixed dollar amount.
Kayla Manousselis Ethnicity
Kayla Manousselis’s ethnicity is not clearly documented by a primary source.
Several biography websites describe her as Caucasian or Greek American, but these descriptions are inconsistent and are often repeated without supporting documentation.
Her nationality is more consistently reported as American. Unless Kayla herself provides a definitive statement about her ethnic background, specific ethnicity claims should be treated as unverified.
Kayla Manousselis Nationality
Kayla Manousselis is American and was born in the United States, according to multiple biographical sources. Famous Birthdays lists her birthplace as the United States.
Her professional career is primarily connected to the American social media and influencer market, particularly through TikTok, Instagram and fitness related brand partnerships.
