How to Measure the Inseam of Your Pants
Knowing how to measure the inseam of your pants is essential. When you’re in the store looking to buy a pair of pants, one of the most critical measurements to remember isn’t your waist size or height. It’s your inseam (the measurement from the bottom of your crotch to your ankles). It must be one of the first measurements you should ask to get when shopping for new clothes. Once you know your inseam length, you can find pants that fit perfectly and look great on you all day.
Key Takeaways
- The inseam of your pants is the length from the crotch seam to the ankle of the leg along the inside seam.
- You can use a mirror to measure the inseam of your pants.
- A great-fitting pair of pants can also help you when measuring your pants’ inseam.
- You can measure your pants’ inseam while standing against the wall.
What is an Inseam?
An inseam is a length from your crotch seam to your ankle. It’s a measurement that applies no matter what type of pants you buy, whether jeans, khakis, or dress pants.
The inseam can be tricky if you don’t know what it means. To get an accurate measurement, you’ll have to measure the distance from your crotch down to your ankles and note the size in inches or centimeters.
A Guide on How to Measure the Inseam of Your Pants

Knowing how to measure the inseam of your pants makes shopping for new pants a straightforward exercise. You can use a few methods to measure your inseam to get perfect-fitting pants. This page gives a detailed guide on how to measure your pants’ inseam utilizing each technique.
Method 1: Let Someone Measure Your Inseam
Did you know that you can effectively measure the inseam of your pants by letting someone measure for you? Here is how to do it:
- Ask a friend or a family member to help you with the measurement.
- Wear leggings or tight-fitting clothing for an accurate measurement.
- Ensure you stand with your feet shoulder-width apart and a straight back.
- Let the person taking the measurement place a measuring tape on the inside of your leg, starting from your crotch area, and roll it down to your ankle’s bottom or any other desired length of your pants while ensuring that the measuring tape is not only straight but also parallel to the ground.
- Ask the person measuring you to note the length in centimeters or inches.
Note: It is advisable to wear the shoes you plan to wear with the pants when measuring to get an accurate size. It would help to take the measurement more than once to ensure you get it correctly.
Method 2: DIY Using a Mirror
Measuring your pants’ inseam accurately might be challenging, but it is doable. If you want to do this yourself, measure your inseam by following these steps:
- Ensure you have a full-length mirror and a measuring tape.
- Stand with your feet shoulder-length apart and a straight back in front of a mirror.
- Place the tip end of your tape measure at the crotch region and let it roll down to the desired length or the bottom of your ankle.
- Look at the mirror to ensure that the tape is straight and parallel to the ground.
- Note the measurement, either in inches or centimeters, and you are done.
Note: Measuring the inseam of your pants using a mirror might not be as accurate as letting someone measure for you. However, it will give you a rough estimate.
Method 3: Measure the Inseam of Your Pants while Standing Against the Wall
Here is how to effectively measure your pants’ inseam while standing against the wall:
- Find a wall, stand with your back against it, and ensure your back is straight and your feet are flat on the ground.
- Make sure you wear what you usually wear when shopping for pants: shoes, socks, and other accessories that may affect your inseam measurement.
- Place a measuring tape on the inside of your leg, starting from the crotch region.
- While holding the measuring tape in place, extend it down to the desired length (in most cases, the bottom of your ankle) while ensuring that the tape is straight and parallel to the ground.
- Note the measurement and use it to purchase a perfect pair of fitting pants.
Method 4: Measure Your Inseam Using a Great Fitting Pair of Pants

It is possible to measure the inseam of your pants using another pair of fitting pants. You’ll want to find a pair of pants that fit perfectly to measure your inseam. Be sure they’re not too tight or too loose. The pair of pants should be similar to the one you want to buy.
Follow this simple process to measure the inseam of your pants using another fitting pair of pants:
- Look for a well-fitting pair of pants with the same cut as the ones you wish to purchase. For instance, if you wish to buy a pair of jeans, use another perfectly fitting pair of jeans to take the measurement.
- Lay the pair of pants you wish to measure on a flat surface like a table or any other surface.
- Fold the pants you wish to use as a measuring tool in half lengthwise, ensuring they are smooth and free of wrinkles.
- Take the inseam measurement (the distance from the crotch area to the bottom of the leg along the inside seam).
The measurement you get is your inseam measurement, and you’ll use it when purchasing new pants of the same cut. However, trying new pants before buying them will always be great to ensure you get a perfect fit.
