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.

  1. 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
  • Russia (female sizes).

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 the 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.
