Normalized FFMI Calculator (Height-Adjusted)
FFMI with Kouri's +6.1×(1.8 − height) correction so tall and short lifters compare on equal footing.
Raw FFMI systematically flatters short athletes because lean mass doesn't scale perfectly with height² — Kouri's correction renormalises everyone to a 1.80 m reference. It matters most more than ~10 cm away from 1.80 m; at 1.68 m the default here gains ~0.7 points.
