The jeans size calculator is a simple tool to assess your measurements in American, European, British, and Italian size charts all in the blink of an eye! 👖

We know that finding your jeans size might be confusing — so, in the article below, we won't just tell you how to find your jeans size, we will also explain how do jeans sizes work and what are the main differences in jean types.

How to use the jeans size calculator?

The what is my jean size calculator will deliver your results once you complete 4 simple steps:

  1. Input your sex

    Check the section below for specific male & female size charts.

  2. Decide whether you'd like to measure yourself, or a pair of jeans

    • I'm measuring myself — you need to find your waist length. In order to do that, you need to find the circumference of your belly, measured at the level of your belly button.

    • I'm measuring a pair of jeans — lay your jeans flat on a surface and measure their width from left to right, at the level of the waist button, over the zipper.

💡 When you find the perfect fit, double the jeans' width to get your waist length.

  1. Enter the measured width or waist.

  2. Measure and enter the length of your jeans/legs

What is my length in jeans?

  • I'm measuring myself — The jeans length should be measured from your groin to the point above your ankles (or another desired length — 3/4 of the leg, foot sole, just above the knee — depending on the type of trousers) on the inner part of your thigh/calf.

  • I'm measuring a pair of jeans — measure the jeans' inner length, following the inner seam, to the bottom of the jean leg.

🎉 Your results are here! 🎉

We included sizes from:

  • The United States of America;
  • European Union;
  • The United Kingdom;
  • Italy;
  • Japan (female sizes); and

What is my jeans size? - jeans size charts

Jeans sizes in the US are based on the waist/length ratio, given in inches (in).

For example, a male with a jeans waist size of 28 in and leg length of 30 in will have a jeans size of 28/30. We can also use the standard S/M/L sizes or the simple numerical value (30-50 for men, 0-30 for women).

💡 Our jeans size calculator accepts values in both metric and imperial.

❗ Remember, less typical jeans shapes and lesser-known brands may require different measurements and may not follow the charts presented below.

FAQ

What size is a 32 in women's jeans?

How do I measure the length of a pair of jeans?

To measure the length of the jeans, follow these steps:

  1. Place the jeans flat on a surface.

  2. Using a measuring tape, measure from the center of the crotch seam to the bottom of the leg hem.

    This measurement is usually known as the inseam length.

  3. Determine your standardized jean length, which can be short (30 in or 76 cm), regular (32 in or 81 cm), or long (34 in or 86 cm).

  1. Wrap a measuring tape around your natural waist, which is the narrowest part of your torso, to get your waist measurement.

  2. Measure the inseam by running the tape from your crotch to your ankle.

  3. Consult the size chart of the jeans brand you're interested in to find the size that corresponds to your measurements. Keep in mind that different brands may have different sizing.
