What is the difference between anthropometric and body composition measurements?

Overview

Anthropometrics and body composition are closely related concepts that are often used together, but they measure different things. Understanding the distinction helps you choose the right measurements for your assessment goals.

Anthropometric Variables

Anthropometrics describe the physical dimensions and proportions of the human body. Common examples include:

• Body Mass Index (BMI) — calculated from height and weight
• Waist circumference
• Waist-to-height ratio
• Waist-to-hip ratio
• True limb lengths

Body Composition Variables

Body composition describes what the body is made of at a tissue level. Common examples include:

• Body fat mass
• Lean mass
• Fat-free mass
• Trunk fat mass
• Body fat percentage

Notes

• These two categories are complementary. A thorough health assessment often draws on both types of measurements.
• Many body composition tools use equations to estimate values rather than measuring them directly — keep this in mind when interpreting results.
