Calipers Body Fat Calculator
🧪 Caliper Body Fat Calculator (7-Site Method)
📘 Understanding Caliper Body Fat Measurement
Caliper-based body fat measurement is a widely used method to estimate body composition using skinfold thickness. Using a caliper, seven specific body sites are measured and used in equations like the Jackson-Pollock 7-site formula to calculate body fat percentage.
📍 Skinfold Sites for Measurement
- Chest
- Abdomen
- Thigh
- Tricep
- Suprailiac
- Subscapular
- Midaxillary
🧮 Formula Used
For men and women, Jackson & Pollock 7-site equation estimates body density:
Body Density = 1.112 - 0.00043499 × sum + 0.00000055 × sum² - 0.00028826 × age
Then, Siri equation converts to fat %:
Body Fat % = (495 / Body Density) - 450
💪 Benefits of Skinfold Body Fat Test
- Quick, inexpensive
- Portable & repeatable
- Gives lean mass & fat mass estimates
📉 Limitations
- Accuracy depends on skill
- Not ideal for very obese or very lean subjects
- Not as precise as DEXA or hydrostatic weighing
