Estimate body fat from skinfold calipers.
Switch between Jackson-Pollock 3-site, 4-site, and 7-site protocols. The 3-site method is the default and all caliper measurements should be entered in millimeters.

Body Fat Caliper Test
Use this body fat caliper test to estimate body fat percentage with 3-site, 4-site, or 7-site Jackson-Pollock skinfold measurements.
How it works
How to use the body fat caliper test
Body Fat Caliper Test is intended for people who use skinfold calipers and want a repeatable body fat estimate between bigger checkpoints. Use it to estimate body composition from caliper measurements when you want a more hands-on checkpoint than scale weight alone.
Choose the protocol you want to use, take the required skinfold sites carefully, enter each reading in millimeters, and stay consistent with who is doing the measurements. The calculator returns a caliper-based body fat estimate.
Caliper readings can shift a lot with poor pinch technique, inconsistent site placement, hydration, and who is taking the measurement. Use the result to compare trends over time, then pair it with photos, bodyweight, performance, and how lean you actually look.
