Prince William and Catherine, Princess of Wales, form one of the most visible modern royal partnerships, balancing public duties with family life in a structure shaped by tradition and contemporary expectations. As the elder son of Charles III and Diana, and the eldest child of his generation, William represents a stabilizing force alongside Kate, an experienced professional who has evolved into a senior working royal. Together they lead a growing family centered on their three children—Prince George, Princess Charlotte, and Prince Louis—and are positioned as future monarchs in a reformed, more compact royal household.
Royal Titles and Styles Explained
In the British monarchy, precise titles communicate lineage, rank, and constitutional role. William and Kate’s styles reflect their positions as Prince and Princess of Wales, parents, and senior members of the royal family. Their children also carry specific titles that depend on birth order and marriage status.
William and Kate’s Styles
William holds the title Prince of Wales, a personal grant from the monarch, and is commonly referred to as His Royal Highness Prince William, Prince of Wales. Kate is Her Royal Highness The Princess of Wales. Within close circles and official documents, they may also be referenced as Duke and Duchess of Cambridge, reflecting the earlier dukedom William received on their wedding day, though Wales remains their primary style.
Their Children’s Titles
Because William is the eldest son of the Prince of Wales, his children are entitled to use the style of Royal Highness and the title Prince or Princess of their father’s highest-ranking territorial designation. To balance family consistency and practicality, their children were granted the titles Prince or Princess with the territorial suffix Cambridge at birth, rather than automatically as grandchildren of the Prince of Wales or children of the Prince of Wales. Each child also holds a courtesy family title.
| Name | Title at Birth | Style and Courtesy Title | Notes |
|---|---|---|---|
| Prince George of Cambridge | His Royal Highness Prince George of Cambridge | Prince George of Cambridge (HRH) | Eldest child; first in line to William’s eventual dukedom before current arrangements |
| Princess Charlotte of Cambridge | Her Royal Highness Princess Charlotte of Cambridge | Princess Charlotte of Cambridge (HRH) | Second child; ahead of Louis in birth order |

The Immediate Family Unit
The core of the household consists of William and Kate with their three children: Prince George, born 2013; Princess Charlotte, born 2015; and Prince Louis, born 2018. Their roles are framed by preparation and public service, with George positioned as the future monarch under the current line of succession, Charlotte as a trailblazer in modern princesshood, and Louis representing the younger generation of royal duties.
