Accurate hip measurement is essential for women using the Navy Method body fat calculator

Key Point

Hip measurement is required for women in the Navy Method formula. Measure at the widest point of your buttocks for accurate results.

Why Hip Measurement Matters

The Navy Method uses hip circumference for women because fat distribution differs between sexes. Women typically store more fat in the hip and thigh area, making this measurement crucial for accurate body fat estimation.

Step-by-Step Instructions

Stand straight: Stand with feet together, weight evenly distributed, looking straight ahead.
Find the widest point: Locate the widest part of your buttocks/hips. This is usually around the hip bone level.
Position the tape: Wrap a flexible measuring tape around your hips at the widest point, keeping it parallel to the floor.
Check alignment: Use a mirror to ensure the tape is level all the way around and not twisted.
Read the measurement: Exhale normally and read the measurement where the tape meets. Do not pull tight or leave slack.

Tips for Accuracy

Measure directly on skin or over thin, form-fitting clothing
Take 2-3 measurements and use the average
Measure at the same time of day for consistency
Have someone help you if possible for better accuracy

Common Mistakes to Avoid

Wrong position: Measuring too high (at waist) or too low (at thighs) instead of the widest point
Tape not level: Tape tilting up or down instead of being parallel to the floor
Pulling too tight: Compressing the skin gives inaccurate readings. The tape should be snug but not tight.

Frequently Asked Questions

Where exactly should I measure my hips?

At the widest point of your buttocks, typically around the level of your hip bones. Stand sideways in a mirror to find the widest point.

Should I measure over clothes?

Ideally measure on bare skin or over thin underwear. Thick clothing can add 1-2 cm to your measurement.

Why is hip measurement only for women?

The Navy Method formula accounts for sex differences in fat distribution. Women store more fat in hips/thighs, so this measurement improves accuracy for women.

How often should I remeasure?

For tracking progress, measure weekly at the same time. For body fat calculations, remeasure whenever you recalculate.

My measurements vary each time. What should I do?

Take 3 measurements and use the average. Ensure consistent positioning and tape tension each time.

Does hip measurement change with weight loss?

Yes, hip circumference typically decreases with fat loss, though the rate varies by individual and where you tend to lose fat first.
