Work out fev1 predicted instantly with clear inputs, formula shown and shareable results.
Uses the European Community for Steel and Coal (ECSC/ERS 1993) reference equations for FEV1 in adults of European descent.
ECSC 1993 reference equations
Men: FEV1 (L) = 4.30 x height(m) - 0.029 x age - 2.49. Women: FEV1 (L) = 3.95 x height(m) - 0.025 x age - 2.60

Yes. GLI-2012 multi-ethnic equations are now preferred where available; the ECSC set applies to European-descent adults.
Below 80% of predicted is the classic cut-off, though the lower limit of normal from GLI is statistically better.
