What is HowTall?

HowTall is a simple web tool to compare your height with celebrities, animals, buildings and other objects. Silhouettes are scaled automatically so differences are visible at a glance.

Where does celebrity height data come from?

Do you store my data?

BMI and centile inputs are processed locally. When you share a comparison, we store anonymized data to generate a short link and basic stats. No personal data is stored.
