Bedridden Patient Height Estimator

Your details

Choose the measurement you have taken. Knee height (Chumlea 1994) is the most validated for older adults.
Biological sex is used by all sex-specific formulas.
Age in years. Several formulas include an age correction term.
years
The Chumlea 1994 paper published separate equations for White and Black adults.
Measure from the sole of the heel to the anterior surface of the thigh with the knee flexed at 90 degrees. Use a knee-height caliper when available.

Estimated height: 165.8 cm (5 ft 5.3 in)

  • The estimated standing height is 165.8 cm (65.3 in), based on the Chumlea 1994 - White men formula.
  • This estimate is suitable for drug-dosing calculations (ideal body weight, adjusted body weight), nutritional assessment, and BMI computation when direct measurement is impossible.
  • The standard error of these formulas is roughly 2-4 cm, so results should be interpreted in clinical context rather than treated as exact measurements.
  • Knee height is most accurate when measured with a proper knee-height caliper rather than a standard tape, especially in patients with contractures.

Next stepUse this estimate as the height input in a BMI, ideal body weight, or nutritional-requirement calculator. Confirm with a second method when precision is critical.
