Measuring Jeans & Trousers

Waist Circumference

1) Place the tape measure on the center of the button on the inside waistband of the jeans/trousers.

2) Incrementally work the tape measure along the inside of the waistband, stopping at short intervals to be certain you maintain tension on the tape measure and obtain an accurate measure of distance between each stop/start point.

3) Complete this measuring exercise by making one last measure between your last stop point and the outside edge of the buttonhole on the inside of the waistband. The total number you have now derived is the TRUE INTERNAL circumference of the inside waist of the jeans/trousers. Measuring the outside width of the waistband of the jeans/trousers and then doubling that measure does NOT reflect a true INTERNAL circumference measure, as any external doubling method fails to account for fabric lost due to its bulk and from being doubled over. You want to know what the true measure is on the INSIDE, because that is what is going around your waist!

Front Rise

1) The jeans or trousers are buttoned or zipped closed and placed on a flat surface with the front facing down.

2) Smooth out wrinkles, bulges and creases, and SLIGHTLY stretch the garment in length to make sure you are getting as close to a smooth, linear measure as possible that incorporates the true length of material to be measured.

3) Place the measuring tape on the bar tack in the crotch and measure a straight line to the top of the waistband above the top button. The total measure you obtain is the front rise. The front rise is the primary determining factor as to how high the jeans/trousers will sit on your hips, as well as being a good gauge of comfort in this front region.

Thigh Width

1) The jeans or trousers are buttoned or zipped closed and placed on a flat surface with the back facing down.

2) Smooth out wrinkles, bulges and creases, and SLIGHTLY stretch the garment in length to make sure you are getting as close to a smooth, linear measure as possible that incorporates the true length of material to be measured.

3) Place the measuring tape 1” below the crotch on the inside edge of the jean/trouser leg and measure horizontally in a straight line across the width of the thigh to the outside edge of the jean/trouser leg. The total measure you obtain is the thigh width.

Knee Width

1) The jeans or trousers are placed flat with the back facing down.

2) Smooth out wrinkles, bulges and creases, and SLIGHTLY stretch the garment in length to make sure you are getting as close to a smooth, linear measure as possible that incorporates the true length of material to be measured.

3) Place the measuring tape 14” below the crotch on the outside edge of the jean/trouser leg and measure horizontally in a straight line across the width of the knee to the inside edge of the jean/trouser leg. The total measure you obtain is the knee width.

Sleeve Length

1) The jeans or trousers are placed on a flat surface.

2) Smooth out wrinkles, bulges and creases, and SLIGHTLY stretch the garment in length to make sure you are getting as close to a smooth, linear measure as possible that incorporates the true length of material to be measured.

3) Place the measuring tape on outside edge of the jean/trouser leg and measure horizontally in a straight line across the width of the leg opening to the inside edge of the jean/trouser leg opening. The total measure you obtain is the leg-opening width.

Inseam Length

1) The jeans or trousers are placed on a flat surface.

2) Smooth out wrinkles, bulges and creases, and SLIGHTLY stretch the garment in length to make sure you are getting as close to a smooth, linear measure as possible that incorporates the true length of material to be measured.

3) Place the measuring tape on inside edge of the jean/trouser leg at the crotch center junction seam and measure in a straight line down the inside edge of the leg length running directly next to the inside leg seam, stopping at the end of the leg. The total measure you obtain is the inseam length.
