Game Theory: Super Mario's BIGGEST Secret.....Literally

For seven years, Game Theory has struggled to definitively determine Mario's height, with various methodologies contradicting each other.

• Nintendo's official claim: 5 foot 1 inch (155 centimeters) • No in-game evidence had ever confirmed this height • Various sources and games provided conflicting data

Each time a methodology seemed to work, new evidence would contradict it, making it one of the channel's biggest unsolved mysteries.

After seven years, the channel finally has the clue needed to establish not just Mario's height, but the heights of every character in the Mushroom Kingdom.

Nintendo released a free update to Super Mario Odyssey in February called Luigi's Balloon World, a mini-game where players hide and find balloons across different kingdoms.

The game displays distance measurements in real-world meters, providing a concrete scale reference for in-game measurements.

Using pixel measurements against the in-game ruler and the meter-based distance display, Mario's height was confirmed at 5 feet 1 inch (1 meter 55 centimeters).

• First confirmation from an actual mainline Mario platformer • The use of real-world metrics suggests this was intentional on Nintendo's part • Hints at a potential insider at Nintendo deliberately planting clues

A previous Game Theory video explored whether Rosalina from Super Mario Galaxy is Princess Peach's daughter using genetics and physics.

A storybook in Super Mario Galaxy suggested Rosalina's true nature, written by game director Yoshiaki Koizumi late at night without anyone knowing.

Yoshiaki Koizumi, director of Mario Galaxy and lead producer of Super Mario Odyssey, appears to be deliberately seeding lore clues for theorists to discover.

Game Theory may have an inside source at Nintendo providing intentional clues about the Mario universe's lore and secrets.

• Official 3D models ripped from games were obtained from The Models Resource • Models were imported into Blender, free open-source 3D graphics software • Mario Kart Wii was used as the reference to compare all characters at the same scale

• Luigi, Wario, and Yoshi: 5 foot 9 inches (175 centimeters) • Peach and Daisy: 6 foot tall (183 centimeters) • Rosalina: 7 foot 3 inches (221 centimeters) • Waluigi: 7 foot 7 inches (231 centimeters)

Waluigi is taller than Yao Ming, one of the tallest NBA players ever at 7 foot 6 inches, but still shorter than Robert Wadlow, the tallest human in recorded history at 8 foot 11 inches.

Bowser was excluded from measurements because he changes heights frequently throughout different games and appearances.

Mario Kart 8 Deluxe assigns each character an invisible weight number, with Mario assigned a weight of 6 corresponding to approximately 90 kilograms (198 pounds), meaning each weight unit equals 15 kilograms (33 pounds).

• Mario and Luigi: 198 pounds (90 kilograms) • Peach: 132 pounds (60 kilograms) • Rosalina: 231 pounds (105 kilograms) • Waluigi: 264 pounds (120 kilograms) • Wario: 330 pounds (155 kilograms)

This methodology was cross-checked with calculations from another analysis using water propulsion mechanics from Super Mario Sunshine, producing consistent results.

Characters with zero weight values, like Baby Peach and Baby Rosalina, are explained as being rounded down from weights under 16.5 pounds, which is normal for newborns.

Body Mass Index (BMI) is calculated by dividing mass in kilograms by height in meters squared, according to CDC standards for fitness levels.

• Under 18.5: Underweight • 18.5 to 25: Normal • 25 to 30: Overweight • 30 to 40: Obese • Above 40: Morbidly obese

Every character falls into unhealthy ranges: Daisy and Peach are underweight, Luigi is overweight, Mario is obese, and Wario is morbidly obese.

Only two characters have healthy BMI scores: Waluigi with a BMI of 22.1, and Rosalina, though Waluigi's health became the surprising conclusion as the kingdom's real threat is their collective eating habits.

The biggest threat to the Mushroom Kingdom is not Bowser or any villain, but the unhealthy eating habits and lifestyle choices of its inhabitants.

Waluigi, despite being the tallest character and rejected from Super Smash Bros, is the only commonly featured character with a healthy BMI, making him an unintended symbol of fitness.

If Waluigi's body shape defines what is healthy in the Mushroom Kingdom, then the kingdom has serious health problems, yet he remains a meme character rather than celebrated.

Rosalina also maintains a healthy BMI, but her inclusion was deemed less dramatic for the conclusion than highlighting Waluigi's unexpected health status.
