The Estimated Height of Prince Louis in Late 2025

Determining the exact height of a young royal like Prince Louis is challenging, as the Palace maintains a strict policy of privacy, especially concerning personal metrics. However, by combining recent public observations with established pediatric data for a boy nearing his eighth birthday, we can form a highly educated estimate.

The Informed Estimate: 53 to 55 Inches (135 to 140 cm)

As of December 2025, based on his age and the visual evidence of his rapid growth, Prince Louis is estimated to be approximately 53 to 55 inches (135 to 140 cm) tall. This places him at the higher end of the growth curve for boys his age.

Contextualizing the Estimate:

• Average for Age: The Centers for Disease Control and Prevention (CDC) data indicates that the average height for a 7-year-old boy is typically between 50.5 and 53.5 inches (128 to 136 cm).
• Public Perception: Reports from royal events in late 2024 and throughout 2025, such as the annual Christmas carol service, consistently highlighted how "tall" and "grown-up" Prince Louis appeared next to his mother, Princess Catherine. This suggests he is tracking above the 50th percentile, likely closer to the 75th or 90th percentile for his age group.
• Comparison to Siblings: While all three Wales children are considered tall, Prince Louis is often visually compared to his older brother, Prince George, who is also notably tall for his age, reinforcing the family's genetic predisposition for height.

This rapid growth phase is perfectly normal. Between the ages of 6 and 8, children typically experience steady growth, usually gaining about 2 to 2.5 inches (5 to 6 cm) per year before the onset of the pubertal growth spurt, which for boys can start anywhere from age 10 to 16. Prince Louis is currently in this steady, pre-pubertal growth phase, making his noticeable height gain a key topic of discussion.

The Genetic Advantage: Why Prince Louis Is So Tall

The primary reason for Prince Louis's impressive stature lies in the exceptional height of his parents. Genetics plays the most significant role in determining a child's adult height, and the Prince and Princess of Wales are two of the tallest members of the immediate Royal Family.

1. Prince William, The Prince of Wales

Prince William is widely recognized as one of the tallest senior royals. His reported official height is 6 feet 3 inches (191 cm). This imposing height is a dominant genetic trait that is highly likely to be passed down to his children, including Prince Louis. William’s stature immediately gives his children a high ceiling for their own adult height.

2. Princess Catherine, The Princess of Wales

Princess Catherine is also significantly taller than the average British woman. Her reported height is 5 feet 9 inches (175 cm). This height is considered statuesque and contributes a strong "tall gene" to the family's lineage. The combination of a 6'3" father and a 5'9" mother almost guarantees that their sons will grow to be very tall men, potentially exceeding their father's height.

The Mid-Parental Height Formula (MPH)

A simple, though not fully predictive, formula used by pediatricians to estimate a child's eventual adult height is the Mid-Parental Height (MPH) formula. This calculation provides a target range based on the average of the parents' heights, adjusted for gender.

• For a boy: (Father's Height + Mother's Height + 5 inches) / 2
• Calculation for Prince Louis: (75 inches + 69 inches + 5 inches) / 2 = 74.5 inches
• Estimated Adult Height: 74.5 inches, or approximately 6 feet 2.5 inches (189 cm).

Given that this formula is only an average, and Prince Louis is already tracking tall, he could easily reach or even surpass the height of his father, Prince William, potentially becoming one of the tallest British monarchs in history, alongside his brother, Prince George.
