Hip measurement vs seat measurement for pants
Key takeaways
- Measure the fullest part of the hips and seat in one level loop.
- Keep the tape parallel to the floor and snug but not pressing in.
- Check how the chart defines the measurement before you compare numbers.
- Measure over thin clothing or underwear, not over jeans.
Hips and seat usually mean the same loop
On most pants charts, the hip and seat measurements describe the same thing: the widest loop around the lower body, taken across the fullest part of the seat.
The terms differ because brands use them differently, not because there are two separate measurements. If a chart lists both, read its notes to see whether it defines them separately.
How to take the measurement
Stand with your feet together and your weight even. Wrap a soft tape around the fullest part, checking in a mirror that the tape stays level at the back and the front.
The tape should lie flat against you without pressing into the skin. Read the measurement while breathing normally.
When the chart defines it differently
Some charts describe the hip as a set point on the body rather than the fullest part. If the chart gives its own landmark, use that landmark, even if it differs from where you would naturally measure.
This site's measurement standard is a published reference, not a record of fit testing. Brand charts can differ from it, so the brand's own definition should take priority when you are buying from that brand.

Frequently asked questions
- Is the seat the same as the hips on a size chart?
- Usually yes. Most pants charts use the two words for the fullest loop around the lower body. If the chart defines them separately, follow its notes.
- Should the tape be tight?
- No. Keep it snug and level, lying flat against you without pressing in. A tape pulled tight gives a smaller figure than the pants will need.
