The Navy's BCA is based on the maximum weight for height screening and body fat percentage estimation. The Body Fat estimation is based on circumference measurements. The Navy, like the other services, uses weight charts (see below) for initial screening.

Due to muscle mass and other factors, exceeding the weight indicated on the chart, doesn't necessarily mean you are considered overweight. It means that the Navy needs to perform a body-fat measurement to determine if you fall within the prescribed Navy Body Fat standards.

The Navy's Body Fat Standards are:

- Male - 17 to 39 years old = 22 percent
- Male - 40 + years old = 23 percent
- Female - 17 to 39 years old = 33 percent
- Female - 40 + years old= 34 percent
