With this handy Body Fat Percentage Calculator you can estimate your fat percentage using nothing more than a tape measure and bathroom scales. Of course, it won’t provide the same accuracy as direct measurements, but it will work quite well where just an approximate indication is required.
The 4 girth measurements that you need to take for plugging into the Body Fat Percentage Calculator are as follows:
Waist Measurement – measured across your belly button.
Hip Measurement – measured at the widest point of your buttocks.
Forearm Measurement – measured at the widest point.
Wrist Measurement – measured at the widest point.
The best time to use this calculator is the first thing in the morning. Your body weight and waist measurements are the most accurate just after you wake up from 7 to 8 hours of sleep.
If you’re on a weight loss program or if you need to know your body fat percentage reasonably accurately for some other reason, you shouldn’t really rely on this calculator. The most accurate methods of determining your body fat percentage are hydrostatic weighing, Bod Pod testing, and Dexa Scanning.
Using body fat bathroom scales is also a great way to track your fat loss progress on a weight loss program. This calculator won’t accurately track fat loss progress over time, it’s only meant for an approximate, one-off snap-shot estimate.
