When people search “how old is Prince William kids,” they’re usually looking for a quick answer. But behind that simple question is a much bigger story—one that includes royal tradition, modern parenting, public curiosity, and the fascinating stages of childhood unfolding inside the British royal family.
Prince William, the Prince of Wales, and his wife Catherine, Princess of Wales (Kate Middleton), are parents to three children who are growing up in front of the world while still being carefully protected from too much public exposure. Their ages are often discussed not just out of curiosity, but because each child represents the future of the monarchy in a different way.
In this in-depth article, we’ll explore how old Prince William’s kids are, what those ages mean in a royal context, and how each child is growing into their role. This guide is written casually but with expert-level detail, giving you far more than just numbers.
Who Are Prince William’s Kids?
Before diving into ages, it’s important to understand who Prince William’s children are and why they matter so much to the British monarchy.
Prince William and Catherine have three children:
-
Prince George Alexander Louis
-
Princess Charlotte Elizabeth Diana
-
Prince Louis Arthur Charles
Each child was born into global attention, with their births announced to the world and celebrated across the UK and beyond. Yet despite their royal status, William and Kate have made a deliberate effort to raise their children as normally as possible.
Their ages are often searched because the public likes to track milestones—first days of school, appearances at royal events, and moments that hint at their future responsibilities.
How Old Is Prince William’s Eldest Child, Prince George?
Prince George Alexander Louis was born on July 22, 2013, making him 12 years old as of late 2025.
As the eldest child, Prince George holds a particularly important position. He is second in line to the British throne, after his father, Prince William. This means that from a very young age, his life has been shaped by preparation, protocol, and public attention.
At 12 years old, Prince George is entering a key transitional stage. He is no longer seen as a small child but not yet a teenager. This age often brings increased expectations, especially for someone who will one day become king. He has already begun attending more significant royal events, learning formal behavior, and understanding the responsibilities attached to his title.
Despite this, his parents work hard to ensure he enjoys a regular childhood. He attends school, plays sports, and spends time with his siblings away from cameras. His age reflects a balance between growing awareness of duty and the freedom to simply be a kid.
What Prince George’s Age Means for His Royal Future
At 12, Prince George is at an age where royal education subtly begins to take shape. While he is not being trained as a monarch in a strict sense, his upbringing includes lessons in history, leadership, and public service.
This age is often when royal children begin to understand why people recognize them and what their family represents. Prince George’s appearances at major events—such as coronations or national celebrations—are carefully chosen to match his maturity level.
His age also influences public interest. Many people wonder how fast he is growing up because his life milestones are closely linked to the future of the monarchy. Each year brings him one step closer to adulthood, and his development is watched with great interest both in the UK and worldwide.
How Old Is Princess Charlotte, Prince William’s Daughter?
Princess Charlotte Elizabeth Diana was born on May 2, 2015, which makes her 10 years old as of 2025.
As the middle child, Princess Charlotte occupies a unique position within the royal family. She is third in line to the throne, following her father and older brother. Notably, she made history by becoming the first British princess to retain her place in the line of succession ahead of a younger brother, thanks to modern succession laws.
At 10 years old, Princess Charlotte is often described as confident, expressive, and self-assured. Her age places her in a stage of growing independence, where personality traits become more visible. Public appearances have shown her to be composed, observant, and occasionally playful—qualities that resonate with many royal watchers.
Her age also means she is beginning to understand her royal identity while still enjoying the freedom of childhood. Like her brothers, she attends school and participates in everyday activities that help ground her upbringing.
Princess Charlotte’s Age and Her Growing Public Role
Princess Charlotte’s age has brought increased public interest, especially because she often displays a strong presence during official events. At 10, children typically become more socially aware, and Charlotte appears comfortable in structured public settings.
This doesn’t mean she is under pressure to perform. Instead, her parents carefully limit her exposure to ensure she is not overwhelmed. Her age allows for brief, meaningful appearances that introduce her to royal life without demanding too much.
Many royal experts believe that Princess Charlotte’s age is an ideal point for shaping confidence and emotional intelligence. She is learning how to balance formality with warmth—an important skill for any future royal role she may take on.
How Old Is Prince Louis, Prince William’s Youngest Child?
Prince Louis Arthur Charles was born on April 23, 2018, making him 7 years old in 2025.
As the youngest of Prince William’s kids, Prince Louis is often seen as the most playful and expressive. His age places him firmly in early childhood, where curiosity, energy, and humor are at their peak.
At 7, Prince Louis has become a favorite among royal fans, largely because of his candid reactions during public appearances. Whether waving enthusiastically or making funny faces, his behavior reflects the natural innocence of his age.
Despite this lighthearted image, Prince Louis is also growing quickly. He has begun formal schooling and is learning the structure and discipline that comes with both education and royal life.
What Being the Youngest Means at Prince Louis’s Age
Being 7 years old comes with a very different experience compared to his older siblings. Prince Louis is not under the same level of expectation as Prince George, nor is he as closely observed as Princess Charlotte during events.
This allows him greater freedom to express himself naturally. His age means he is still learning how to behave in public, and occasional playful moments are seen as charming rather than problematic.
Prince William and Kate have spoken about allowing their youngest child to enjoy his youth without excessive pressure. At this age, emotional development, creativity, and confidence are far more important than formal royal duties.
How Prince William Balances Parenting Kids of Different Ages
One of the most interesting aspects of asking “how old is Prince William kids” is understanding how their father adjusts his parenting style for each age group.
Parenting a 12-year-old, a 10-year-old, and a 7-year-old requires flexibility. Each child has different emotional needs, learning styles, and levels of understanding. Prince William has often emphasized the importance of mental health, empathy, and open communication in raising his children.
The older children, George and Charlotte, are at ages where they can ask deeper questions about their roles and responsibilities. Louis, on the other hand, is still focused on play, imagination, and basic routines. William and Kate tailor their approach to ensure each child feels supported without being compared to their siblings.
Why People Are So Curious About the Ages of Prince William’s Kids
The popularity of searches like “how old is Prince William kids” reflects more than casual interest. The royal family represents continuity, and ages help people understand where the monarchy stands in its timeline.
Seeing the children grow reminds the public that time is moving forward. Prince George’s age, in particular, is symbolic because it marks the next generation of leadership. Princess Charlotte and Prince Louis represent modernity, diversity of roles, and a changing royal image.
Ages also humanize the royals. Knowing that Prince William’s kids are at the same developmental stages as millions of other children around the world makes them more relatable.
How the Children’s Ages Shape Their Education

At 12, Prince George is transitioning into more advanced academic work and personal responsibility. Princess Charlotte, at 10, is building foundational skills while developing confidence and independence. Prince Louis, at 7, is focused on early learning, creativity, and social development.
Despite their royal status, their education is designed to be as normal as possible. Their parents strongly believe that understanding everyday life is essential for future leadership and empathy.
The Future: How Their Ages Will Continue to Matter
