How to Measure Hip Circumference:
For Trousers, Pants, and Dresses
The hip measurement is one of the three core circumferences that determine trouser, jean, and dress fit. Master tailors take it at a specific point — and most online guides get the location wrong.
What Is the Hip Measurement?
Your hip measurement is the circumference around the fullest part of your hips and seat — typically about 8 inches (20 cm) below your natural waistline. For most adults, this is where the buttocks are widest.
Tailors distinguish between low hip (full seat, used for trousers and jeans) and high hip (about 4 inches below the waist, used for some women's garments). For men's tailoring, hip almost always refers to the low hip.
Hip measurement is the third leg of the chest-waist-hip triangle that determines whether a trouser pattern fits. A trouser cut to your waist circumference but the wrong hip will pull at the seat, gap at the waistband, or split at the rear seam under sitting load.
Why This Measurement Matters
- ✓Trouser seat fit — too tight at the hip causes pulling, splitting, and visible strain lines
- ✓Drop calculation — your hip-to-waist ratio determines whether you need athletic-fit, classic-fit, or slim-fit grading
- ✓Pocket placement — side and rear pocket geometry is laid out from the hip line
- ✓Sit comfort — a properly-measured hip means trousers don't compress when seated for hours
Step-by-Step: How to Measure Hip Circumference
What You'll Need:
- Soft fabric measuring tape
- Mirror or helper (helpful but not required)
- Form-fitting pants or underwear (avoid thick fabric)
Stand naturally with feet together
Stand on a flat surface with your feet together (not shoulder-width apart — that distorts the hip line). Keep your weight evenly distributed and your body relaxed. Do not suck in or push out.
Find the fullest point
Identify the widest part of your hips and buttocks — usually 7 to 9 inches (18-23 cm) below your natural waist. If you're unsure, run your hands down your sides and feel for where the curve is widest. This is where the tape goes.
Wrap the tape horizontally
Wrap the measuring tape horizontally around your body at the widest point. Keep the tape parallel to the floor — a tilted tape will give a falsely larger or smaller reading. The tape should rest gently on your body, not compress.
Check tape level in the mirror
Look in a mirror or have a helper verify the tape is level all the way around. The most common mistake is the tape riding higher in the back than the front, which underestimates the measurement.
Read at the meeting point
Read the measurement where the zero end of the tape meets the rest. Record in inches or centimeters to the nearest 0.25 inch (0.5 cm). Repeat once or twice — a properly-taken hip should be within 0.25 inch on repeat measurements.
Average Adult Hip Circumference by Height (US Reference)
| Height | Hip (inches) | Hip (cm) |
|---|---|---|
| 5'4" – 5'6" (162–168 cm) | 36" – 38" | 91 – 96 cm |
| 5'7" – 5'9" (170–175 cm) | 38" – 40" | 96 – 102 cm |
| 5'10" – 6'0" (178–183 cm) | 40" – 42" | 102 – 107 cm |
| 6'1" – 6'3" (185–190 cm) | 42" – 44" | 107 – 112 cm |
Common Mistakes
Measuring at the wrong height
Most amateur attempts measure too high (at the natural waist) or too low (at the upper thigh). Always at the widest point of the seat, typically 8 inches below the waist.
Pulling the tape tight
A compressed hip measurement underestimates by 1-2 inches and produces trousers that pull at the seat. The tape should rest on your body without indenting the skin.
Tape not level around the back
Without a mirror or helper, the tape often rides up at the back. This underestimates the measurement by 1-1.5 inches. Always verify the back of the tape is at the same height as the front.
Frequently Asked Questions
Where exactly do I measure my hip?+
At the fullest part of your hips and seat — usually about 8 inches (20 cm) below your natural waistline, where your buttocks are widest. This is the "low hip" measurement used in men's tailoring and most modern women's pattern-making.
What is the difference between high hip and low hip measurement?+
The high hip is measured about 4 inches below the natural waist, where your hip bones sit. The low hip is at the fullest point of the seat, about 8 inches below the waist. Men's trousers use the low hip almost exclusively. Women's pattern-making sometimes uses both.
What is the average hip size for a man?+
The average adult US male low-hip circumference is approximately 40 inches (102 cm). This varies significantly with height — see the table above. Lifters and athletic builds with developed glutes typically run 2-4 inches above the height-based average.
How does hip measurement affect trouser size?+
Trouser patterns are graded primarily off waist circumference, but the seat is shaped to the hip measurement. If your hip-to-waist drop is larger than the brand's fit model assumes (typically 6-8 inches for a standard cut), the trouser will pull at the seat even when the waist fits. This is why athletic-build customers usually need custom or athletic-fit grading.
Should I measure hip with clothes on?+
Measure over thin, form-fitting clothing or directly on bare skin. Thick denim, sweats, or layered clothing add 1-2 inches to the reading and produce trousers that hang too loose at the seat. Underwear or a thin athletic short is the standard.
How often should I re-measure my hip?+
Re-measure any time your weight changes by more than 5-7 pounds, or every 12-18 months for stable adults. Hip circumference responds to weight changes faster than chest or waist for most body types, so this is the measurement that goes stale soonest in your tailor's file.
Why is my hip measurement larger than my waist by 8 inches?+
That is normal and healthy — an 8-10 inch waist-to-hip drop is the median for adult men in good general fitness. Athletes and habitual lifters often have larger drops (10-14 inches) driven by glute and quad development. Smaller drops (under 5 inches) usually indicate visceral fat distribution patterns; consult a physician for context.
