How to Measure Your Inseam

Two Methods:Using a Pair of Pants to Find Your InseamMeasuring Your Inseam With the Help of a Friend

Inseam measurements are required for choosing and tailoring accurate clothing sizes, and may also be necessary for picking the right bicycle. Measure your inseam by extending a soft tape measure from the bottom of your crotch area, down the inside of your leg, and to the bottom of your inner foot. You can also measure your inseam by using a soft tape measure to measure the length of the inner seam (running from the crotch to the hem) of your pants.

Method 1
Using a Pair of Pants to Find Your Inseam

    1
    Fold your pants. Choose a pair of pants that fit you perfectly; they aren't too long or too short, and are just tight enough to be comfortable. You will be measuring the inseam on the pants, so make sure they truly fit you. Fold them in half vertically, so that you can only see a single leg. Be sure this is a pair of pants, and not a very stretchy set of leggings or the like.

    Smooth them out. Lay them out on an ironing board or the floor. Smooth them out so there aren't any wrinkles or bumps, and the fold is evenly lined up.

    Place the start of the measuring tape at the bottom intersection of the crotch. This is the spot on the inside of the leg where one pants leg meets the other. [1]

    Make note of your measurement. The measurement in inches (or centimeters) from the crotch of the pants to the hem is your inseam length.

    Strip down to the bare necessities. Remove your pants or put on a pair of tight fitting workout pants. Measuring with your regular clothes on is likely to leave you with an inaccurate number.

    Stand up straight. Your inseam will be too short if you slouch during the measuring process. Back against a wall to make sure you are keeping good posture.

    Grab a clipboard. Slide a clipboard or very thin hardcover book between your legs. Put it has high as you can, just under the pubic bone. If you are a male, move accessory tissue out of the way so that you can get a true measurement. Make sure the edge of the clipboard is flat against the wall.

    Make your measurement. While you stand up straight, have your friend place the measuring tape at the top of the clipboard, near your thigh and crotch area.

    Make your measurement. Extend the tape down to where it reaches the floor on the inside of your foot. The length in inches (or centimeters) on the tape is the length of your inseam.[2]

Tips

  • Keep in mind that the ideal inseam length will change depending upon the garment or the use. For example, for pants that you plan to wear with boots or high heels, the inseam may need to be 1 or 2 inches (2.5 to 5cm) longer, so that it doesn't touch the ground. An inseam on a pair of shorts will be much shorter than an inseam on a pair of jeans.
