Body Surface Area Calculator: Our 5 Favorite Tools for Measuring BSA

Calculate Your Body Surface Area with's Reliable BSA Calculator offers a reliable Body Surface Area Calculator that utilizes the latest formula derived by scientists to accurately determine your body index. With the Body Surface Area Calculator on, you can easily calculate your BSA and gain a better understanding of your body's surface area.

This article gives you a brief idea about the body surface area calculator and the favorite tools people turn to for acquiring information. 

What is a Body Surface Area Calculator?

A is an online application that calculates the overall surface area of your complete body. It is a more accurate measure of metabolism than body weight and is employed in many scientific domains.

Body surface area, often known as BSA, is crucial because it serves as a more precise measure of metabolic mass. Moreover, fat-free mass is used to calculate metabolic mass. BSA is the most accurate indication of metabolic mass, so it is frequently employed for therapeutic purposes. BSA is also employed in clinical contexts, such as those involving chemotherapy doses and cardiac indices, both of which are related to cancer treatment.

The formula for calculating BSA 

Here comes the tricky part, any tool you select gives you a distinguished set of options to choose from to get the required results, the formulas that are available in most of the online tools are:
  1. Mosteller formula - Calculated by multiplying the height in cm with weight in kilograms
      Formula - BSA = [(W x H)/ 3600] 0.5 
  2. Du Bois formula - BSA = 0.007184 × W0.425 × H0.725
  3. Haycock formula - BSA = 0.024265 × W0.5378 × H0.3964
  4. Gehan and George formula - BSA = 0.0235 × W0.51456 × H0.42246
  5. Boyd formula - BSA = 0.03330 × W(0.6157 - 0.0188 × log10(W) × H0.3
  6. Fujimoto formula - BSA = 0.008883 × W0.444 × H0.663
  7. Takahira formula - BSA = 0.007241 × W0.425 × H0.725
  8. Schlich formula for Women - BSA = 0.000975482 × W0.46 × H1.08
                                        Men - BSA = 0.000579479 × W0.38 × H1.24

Parameters that a BSA calculator uses

BSA may be used to compute the following variables:

1. Cardiovascular index (CI): We may compute by dividing the cardiac output by BSA. The cardiac index should be within the range of 2.5 to 4.0 L/min/m2. The root reason must be found if it falls outside the typical range.
2. SVI (stroke volume index): The Stroke Volume Index is calculated by dividing the stroke volume by the BSA.
3. The SVRI, or systemic vascular resistance index: To obtain the SVRI, divide the systemic vascular resistance by the BSA.
4. The PVRI, or pulmonary vascular resistance index: Is obtained by dividing the vascular resistance by BSA.

Our 5 favorite tools for BSA calculator’s Body Surface Area Calculator 

brings you the most basic format of the. This tool is designed to provide the result quicker and easier. We also keep you in the loop with the previous histories checked upon by oneself. Any unit, including inches, centimeters, feet, and meters, is required for your height and weight in the space provided. After entering your data, click the Calculate button to produce the results.

Based on the result achieved your physician can continue the medication process. 

2. Good Calculator’s Body Surface Area Calculator 

With Good Calculator BSA calculators, you need to know the formals mentioned above to correlate the result you achieve. Though a minimum amount of information needs to be entered to achieve the result, the calculator leaves the choice of selecting the BSA equation to the individual.

After entering all the information, the estimated BSA achieved is accurate. 

3. Total Shape’s Body Surface Area Calculator

Total Shape’s BSA Calculator is a bit different from the other two. This calculator gives you the option to choose the gender. Why am I stressing the gender part? Men and Women are built differently; thus, having a separate calculator gives a more definitive result. 

This calculator has the 1RM Equation option left for the individual to choose from. In the end, the result obtained will be conclusive for the gender. 

4. Global RPh’s BSA Calculator

If you ask me,” Just another app, what difference is this going to make?”
Allow me to explain that GLobal RPh’s BSA calculator gives the option to choose between

  • Height - Inches/Centimeters
  • Weight - Kilograms/Pounds

I know this doesn’t make much of a difference, but again, what if you know your weight only in pounds and don’t want to go through the internet to change the metrics just to view the result? 

5. Calculator Panda’s Body Surface Area Calculator

The BSA calculator of calculator panda is designed to give results so precise as the life of an individual depends on this calculation. Further, this app is designed so that fat-free mass, which is all of a person's body mass that does not include fat, may be used to determine metabolic mass. This comprises the blood, nerves, muscles, inner organs, tendons, and bones. 
In this application, gender-specific, you need to enter the values in the:

  • Weight - Kg/lb
  • Height - Cm/ft/in

Summing up

Your height and weight are the only information the BSA calculator needs to establish your ideal body surface area. The is simple to use and offers findings that are very helpful for determining medicine dosage.

Discover the convenience and precision of's recommended tools for measuring Body Surface Area (BSA). Accurately calculate BSA for medical assessments and treatment strategies, ensuring optimal care for your health.
