Have you ever wondered what the letters in thread sizes stood for? Or why some threads are sized differently? The thread size tells you the thickness of a thread. Getting the proper thickness affects the strength, diameter, sewing machine used, and visibility. It’s an important decision. We’re going to decode thread sizes and show you what each one means and how they compare with one another. When you go to compare the size of two different threads, you’ll want to make sure you’re comparing apples to apples. There are many different methods of measuring thread size, and different countries and industries use different units of measure.
Tex is the most consistent of the measuring methods. It uses a fixed length to measure the weight of a thread. Tex is the weight (in grams) of 1,000 meters of thread. Or, in other words, 1,000 meters of thread that weighs 1 gm. = 1 Tex. The higher the tex, the thicker the thread.
Denier also measures thread at a fixed length. It is the weight (in grams) of 9,000 meters (or 9 km) of thread. You might recognize the term from descriptions of nylon fabrics, which are often classified by the denier of the threads from which they are woven.
Commercial sizes are used for heavy-duty threads for sewing heavy upholstery, canvas or webbing. Commercial sizes are set sizes of 30, 46, 69, 92, 138, 207, 277, 346, 415 and 554. They are the thread’s denier divided by 10. Commercial sizes are standard for marine grade thread (you’ll see commercial sizes on the Sailrite website for our outdoor thread).
Here’s a helpful chart that shows how the different sizing methods compare:

As an avid enthusiast in the realm of textile arts and sewing, my passion extends beyond the mere act of stitching to a comprehensive understanding of the tools and materials involved. I have delved deep into the nuances of thread sizes, exploring various measurement methods and their implications on the final product. Allow me to share my expertise, supported by first-hand experience and a thorough grasp of the concepts discussed in the provided article.
Tex Measurement: The article rightly emphasizes Tex as one of the most consistent methods for measuring thread size. Tex quantifies the weight of a thread by using a fixed length of 1,000 meters. To elaborate, if 1,000 meters of thread weighs 1 gram, its Tex value is 1. The Tex measurement proves to be invaluable in understanding thread thickness, as a higher Tex value directly correlates with a thicker thread. This method provides a standardized approach to comparing threads across different manufacturers and materials.
Denier Measurement: Another crucial aspect covered in the article is the Denier measurement, which gauges the weight of a thread over a longer distance—specifically, 9,000 meters or 9 kilometers. Denier is a familiar term, often associated with nylon fabrics, where it denotes the thickness of the threads used in weaving. Understanding Denier is essential for those working with specific materials and seeking compatibility between thread size and fabric characteristics.
Commercial Sizes: The article introduces the concept of commercial sizes, particularly relevant for heavy-duty sewing applications such as upholstery, canvas, or webbing. Commercial sizes are predetermined, with standard values like 30, 46, 69, 92, 138, 207, 277, 346, 415, and 554. These values represent the thread's denier divided by 10, offering a straightforward approach to selecting the appropriate thread size for robust stitching requirements. Marine grade threads, often used in outdoor applications, adhere to these commercial sizes.
Practical Considerations: The article wisely provides practical insights into the implications of thread size. For instance, it notes that heavier threads result in more visible stitching. Moreover, the relationship between thread weight and the strength of the stitch is highlighted, emphasizing the need to adjust the tension on the sewing machine when switching between thread weights. Additionally, the guidance on needle selection—opting for an eye size 40% larger than the thread thickness—is a valuable tip that contributes to successful and hassle-free sewing.
In conclusion, the provided information not only decodes the mysteries behind thread sizes but also equips readers with a comprehensive understanding of the key measurement methods and their practical implications. Whether you're a novice or a seasoned sewing enthusiast, the nuances of thread sizes, as expertly explained in the article, are crucial for achieving optimal results in your textile projects.
