Grab a measuring tape, and let’s get started!
Women’s Underwear Size Guide: How to Measure
Accurate measurement ensures a perfect fit for women’s underwear. Here’s how to do it:
1. Measure Hip Size:
- Wrap the measuring tape around the fullest part of your hips and buttocks.
- Ensure the tape is level and snug but not too tight.
- For a looser fit, leave a finger’s width between your body and the tape.
2. Measure Waist Size:
- Bend slightly to the side to find the natural crease of your waistline.
- Wrap the tape around your waist at this crease.
- Keep the tape flat and comfortably snug.
3. Find Your Underwear Size: Once you have your measurements, use the chart below to find your size.
| Size | Dress Size | Waist (inches) | Hip (inches) |
|---|---|---|---|
| XS | 0-2 | 24 – 25 | 34.5 – 35.5 |
| S | 4-6 | 26 – 27 | 36 – 37 |

Men’s Underwear Size Guide: How to Measure
Men’s underwear fits differently than women’s, so hip measurements aren’t necessary.
1. Measure Waist Size:
- Start at the top of your hip bone and wrap the tape around your waist, just above your belly button.
- Ensure the tape is level and comfortably snug.
- Take a deep breath to ensure the fit isn’t too tight.
2. Find Your Underwear Size: Match your waist measurement to the chart below.
| Size | Waist (inches) |
|---|---|
| S | 28-30 |
| M | 31-34 |
| L | 35-38 |
| XL | 39-42 |
| 2XL | 43-46 |
What If You’re Between Sizes? For a tailored fit, choose the smaller size. If you prefer a relaxed fit, size up.
