Large Sliding Calipers (also known as large bone calipers or large bone anthropometers) measure major bone breadths—shoulders, hips, elbows, and knees—with high accuracy and repeatability.

Used by strength & conditioning coaches and sports dietitians, they help with:

• Muscle-to-bone ratio
• Structural profiling
• Somatotyping & skeletal tracking
• Asymmetry and injury risk screening
• Training and equipment fit optimization
• ISAK Level 2 & Level 3 certification requirements
