Enter Height ft in — height Feet, Height ft in and Weight lbs and the remaining scenario settings to review body surface area with this tool. BSA is a modeled surface area.
Mosteller BSA = √[(Height in cm × Weight in kg) ÷ 3600]The calculation links Height ft in — height Feet, Height ft in and Weight lbs to body surface area. BSA is a modeled surface area. Different named equations can produce slightly different results from the same measurements.
Enter Height ft in — height Feet, Height ft in and Weight lbs and the remaining scenario settings to review body surface area with this tool. BSA is a modeled surface area.
Estimate body surface area from height and weight using the selected equation. Read the output in square meters, which differs from body mass or body-fat percentage.
BSA is a modeled surface area. Different named equations can produce slightly different results from the same measurements.
Prepare Height ft in — height Feet, Height ft in, Weight lbs, Gender and Age. Enter height and weight in the requested units and record the equation alongside the displayed area.
BSA is a modeled surface area. Different named equations can produce slightly different results from the same measurements. The estimate does not independently determine medicine doses, treatment settings or an individual health assessment. Clinical use requires the relevant protocol and professional verification.
Use the full settings in the worked-example table. They produce Body Surface Area: 1.88. Compare the method and units as well as the displayed number.
The displayed relationship is Mosteller BSA = √[(Height in cm × Weight in kg) ÷ 3600] Enter height and weight in the requested units and record the equation alongside the displayed area.
The estimate does not independently determine medicine doses, treatment settings or an individual health assessment. Clinical use requires the relevant protocol and professional verification. For personal care, discuss the measurements and method with a qualified clinician.
Worked body surface area calculator example. Set Height ft in — height Feet = 5; Height ft in = 9; Weight lbs = 160; Gender = Male; Age = 30. The corresponding output is Body Surface Area: 1.88. BSA is a modeled surface area.
Estimate body surface area from height and weight using the selected equation. Read the output in square meters, which differs from body mass or body-fat percentage.
Enter height and weight in the requested units and record the equation alongside the displayed area.
| Field | Example value | Entry check |
|---|---|---|
| Height ft in — height Feet | 5 | Keep feet and any inch remainder in their separate fields. |
| Height ft in | 9 | Keep feet and any inch remainder in their separate fields. |
| Weight lbs | 160 | Use the measurement unit printed beside this field and a consistent measuring technique. |
| Gender | Male | Use the option required by the selected estimation model. |
| Age | 30 | Use the stated unit and the measurement required by this model. |
Relationship used for this example: Mosteller BSA = √[(Height in cm × Weight in kg) ÷ 3600]
BSA is a modeled surface area. Different named equations can produce slightly different results from the same measurements.
| Output | Displayed result |
|---|---|
| Body Surface Area | 1.88 |
With these settings, body surface area is 1.88. Use the same units and calculation mode when reproducing this example.
BSA is a modeled surface area. Different named equations can produce slightly different results from the same measurements. The estimate does not independently determine medicine doses, treatment settings or an individual health assessment. Clinical use requires the relevant protocol and professional verification.
Replace the illustrative height ft in — height feet value (5) with your own value, then complete the other inputs for the same scenario. Enter height and weight in the requested units and record the equation alongside the displayed area.
