Measurements

The Garmin Index smart scale uses bioelectrical impedance to calculate your body composition. The device sends a small amount of electrical current (which you will not feel) from one foot through your body to the other foot. The device measures the electrical signal after it passes through your body to estimate aspects of your body composition.

For best accuracy, ensure you use the device under the same circumstances and at approximately the same time of day each time you use the device. Activities that temporarily impact your body's weight, hydration, and distribution of water can impact the accuracy of measurements. Garmin recommends waiting two hours before using the device after eating, drinking, exercising, bathing, or visiting a sauna.

Weight trend: The weight trend widget displays your daily weight on a line graph for one month. If you weigh yourself multiple times per day, the trend graph uses the last measurement recorded each day.
Body mass index (BMI): Body mass index is your weight in kilograms divided by your height in meters squared. BMI is often used to estimate if a person is underweight or overweight.
Body fat percentage: Body fat percentage is the percentage of total mass attributed to fat, including essential fat and storage body fat. Essential body fat is required for basic health.
Body water percentage: Water percentage is the percentage of total mass attributed to fluid. This measurement can be used to indicate your level of hydration.
Skeletal muscle mass: Skeletal muscle mass is the total amount of mass attributed to muscle. It is measured in pounds, kilograms, or stones and pounds.
Bone mass: Bone mass is the total amount of mass attributed to bone. It is measured in pounds, kilograms, or stones and pounds.

Customizing the Scale Display

You can turn on and off the widgets and weight metrics that appear on your Garmin Index S2 device.
From your Garmin Connect device menu, select Appearance > Widgets.
After customizing the settings, you must sync by recording a measurement.

If necessary, select the measurement.
Select Delete.
You cannot delete the measurement from your trend graph.
