Why does this show several different weight numbers for the same height?
Each formula (BMI range, Robinson, Miller, Devine, Hamwi) was derived differently, so they don't agree exactly — showing them together gives a range rather than relying on a single, potentially misleading number.
Does this account for body frame size or muscle mass?
No — these are all height-based formulas that don't factor in frame size, muscle mass, or body composition, so an individually appropriate weight can fall outside the ranges shown.
