How to Hem Jeans

Knowing how to hem jeans is an essential clothing skill that saves money, improves fit, and gives your wardrobe a tailored, professional look. Jeans are designed to be durable, but length issues are common because denim is produced in standardized inseams that rarely match real-world bodies. Whether your jeans bunch at the ankles, drag on the floor, or simply don’t sit right with your shoes, hemming solves the problem cleanly and permanently.

This in-depth guide explains how to hem jeans using different techniques—from hand sewing to sewing machines and original hem preservation. Each method is explained from real tailoring experience, with practical advice you can apply at home. Whether you’re a beginner or someone looking to improve results, this article will walk you through the process with clarity and confidence.

Understanding What Hemming Jeans Really Means

Hemming jeans is the process of shortening the leg length while maintaining structure, durability, and appearance. Unlike hemming lightweight fabrics, denim requires specific techniques due to its thickness, weave, and tendency to fray.

A proper hem doesn’t just shorten the jeans—it ensures the leg opening sits correctly, drapes naturally, and holds up after repeated washing. Poor hemming can cause stiffness, puckering, uneven seams, or an obvious “DIY” look.

Why Proper Hemming Matters

. It improves overall body proportion and fit
. It prevents fabric damage from dragging
. It enhances the appearance of footwear
. It increases garment lifespan
. It preserves the original design intent
. It adds a polished, tailored finish

How to Measure Jeans Correctly Before Hemming

Before cutting or stitching anything, correct measurement is the most critical step. Many hemming mistakes happen because jeans are measured while barefoot, unevenly folded, or without considering footwear.

Always measure jeans while wearing the shoes you plan to wear most often.

Jeans should lightly touch the top of the shoe or break slightly at the ankle, depending on style preference.

Accurate Measuring Essentials

. Wear intended shoes during measuring
. Stand naturally on a flat surface
. Fold excess fabric evenly at the hem
. Pin or clip both legs symmetrically
. Measure from inseam, not outer seam
. Double-check before cutting

How to Hem Jeans by Hand

Hemming jeans by hand is ideal for beginners, travelers, or anyone without access to a sewing machine. While it takes more time, hand hemming offers excellent control and surprisingly durable results when done correctly.

This method works best for straight-leg and slim-fit jeans and allows you to carefully manage thick seams without machine tension issues.

A strong needle and heavy thread are essential.

Hand-Hemming Process Explained

. Fold jeans to the desired length and press firmly
. Secure the fold with pins or fabric clips
. Thread a heavy-duty needle with doubled thread
. Use a slip stitch or blind stitch technique
. Keep stitches small and evenly spaced
. Knot securely and reinforce seam ends

Hand hemming creates a subtle finish when done patiently, making it an excellent option for casual or vintage denim.

How to Hem Jeans with Original Hem

Learning how to hem jeans with original hem is the preferred method for preserving factory distressing, fading, and edge texture.

This technique shortens jeans without removing the original hem entirely.

It’s especially popular for premium denim, raw jeans, and designer styles where maintaining authenticity matters.

Original Hem Technique Breakdown

. Measure how much length needs removal
. Cut excess fabric above the original hem
. Fold original hem upward into position
. Stitch around the leg, matching seam lines
. Press flat to reduce bulk
. Trim internal excess if needed

This method maintains the worn-in look while delivering a tailored fit, making it a favorite among professionals.

How to Hem Jeans with a Sewing Machine

Using a sewing machine is the fastest and most durable way to hem jeans. It produces clean, straight seams and handles repeated washing better than hand stitching when done properly.

A heavy-duty needle and denim thread are essential to prevent skipped stitches or broken needles.

Machine Hemming Best Practices

. Use a size 90/14 or 100/16 needle
. Select a straight stitch with longer length
. Sew slowly over thick seam intersections
. Use a hump jumper or folded fabric
. Backstitch at the start and end
. Press the hem flat after sewing

Machine hemming is ideal for regular wear jeans, workwear, and thick denim styles.

FAQs

Can you hem jeans without cutting them?

Yes, folding and stitching techniques allow hemming without cutting, though bulk may increase.

Should jeans be washed before hemming?

Is hemming permanent?

Most hemming methods are permanent unless seams are carefully removed.
