What is Jeans Hemming Explained

We explain in direct, easy-to-understand terms what is meant by "hemming jeans."

Summary

Jeans hemming is the process of shortening the leg or inseam length of a pair of jeans by removing some of the fabric from the bottom.

These photographs demonstrate the before and after effects of hemming alterations made by Williamsburg Garment Company to shorten the inseam of jeans to demonstrate “what jeans hemming is.” The top photograph features a pair of Pure Blue Japan jeans. It displays the altered inseam and leg openings as well as the portions of the hem that was removed.

The below image displays a pair of raw denim jeans with their original hem and full inseam length. A chalk line on the jeans marks the hemming cut line, which also includes a 1/2-inch double fold (1-inch).

A pair of raw denim LeRoy Strauss jeans are shown at their original length, and a chalk line marks the hemming cut line.
A pair of raw denim jeans with yellow chainstitch inside the hem are marked with a chalk line which represents the cut line.

The majority of jeans are sewn with chain-stitched hemming. The average hem measures roughly 1/2 inch tall. A tailor or seamstress double folds the raw edge after cutting to the hem (leg opening). Since each fold measures approximately 1/2 inch, the inseam length must be increased by 1 inch to reach the desired length.

To see what we mean by double folding, and the process of hemming in action. Watch our video “Chain Stitch Hemming in 87 Seconds.”
