For hemming, you need a sewing machine needle size that matches your fabric's weight: use smaller needles (70/10, 80/12) for lightweight fabrics like silk or cotton, medium needles (90/14) for everyday fabrics like linen or poplin, and larger needles (100/16, 110/18) for heavy materials like denim, canvas, or upholstery, often needing a specialized Denim or Jeans needle for those. Always match the needle size to your thread size and fabric type for the best results, avoiding skipped stitches or fabric damage.
Jeans Needle Size: Most experts recommend using a size 90/14 or 100/16 needle for hemming jeans. These sizes are robust enough to handle the thickness of denim without breaking. Sewing Needle Size for Denim: The term “denim needle” usually refers to a size 100/16 needle.
The gauge (abbreviated as “G”) of a needle refers to the size of the hole in the needle. The higher the gauge, the smaller the hole. Needles come in various gauges and lengths.
Denim/ Jeans Heavy wovens and denims 70/10 – 110/18 These needles have a thick, strong shaft and a very sharp point. They are used for stitching denim, canvas, duck and other heavy, tightly woven fabrics. They are also ideal for stitching through multiple fabric layers without breaking.
You Don't Necessarily Need a Jean Needle: While a jean needle is ideal for heavy-duty denim, a universal needle can also work. Use a size 90/14 needle for midweight denim and a 100/16 for thicker denim.
The 90/14 needle and 40-weight thread are a dynamic duo. This medium-weight thread glides effortlessly through the needle's eye, balancing strength and flexibility. It's the gold standard for quilting, garment construction, and embroidery on medium-weight fabrics like cotton, linen, or polyester.
For lightweight denim, a 90/14 needle is usually sufficient. As the fabric gets heavier, you'll want to move up to a 100/16 or even 110/18.
Of all the embroidery needles, a 75/11 is one of the most versatile. It works great on medium-weight fabrics like cotton and linen—and even lighter-weight fabrics if used with regular thread—for both standard embroidery projects and patchwork quilting projects alike!
The needle length and gauge are the same as when the deltoid muscle is used, i.e., 1"–1½” length, 22–25 gauge. You should choose needle length based on the weight of your adult patients, as follows: Adults weighing less than 130 lbs (60 kg): Use of a 1” needle is recommended.
A needle that is too small may require more force to push through the skin, increasing the likelihood of pain and discomfort for the patient. A needle that is too large can cause more tissue damage, resulting in increased pain and bruising at the injection site.
Choosing the Right Gauge for Different Procedures
On the other hand, insulin or vaccines, which are injected subcutaneously, typically use higher-gauge, thinner needles (25G to 30G), which are less invasive and more comfortable for the patient.
Thicker fluids like oil-based suspensions require lower gauges (larger diameter), such as 16G – 20G, to prevent clogging. Standard aqueous solutions typically work well with 21G – 25G. Dilute or water-like solutions may benefit from 25G – 30G, which offer greater precision and reduce the risk of contamination.
Using a Needle Gauge
A needle gauge is a special tool specifically for identifying needles, and probably the easiest way as well. Just insert the needle into each hole to identify the best fit. The needle should fit perfectly in the correct hole and slide in easily with little to no room on the sides.

The term “needle gauge” describes the thickness of a needle. Here's a quick trick to remember: the smaller the gauge number, the thicker the needle. For instance, a 25-gauge (25G) needle is thicker than a 30-gauge (30G) needle. In dentistry, gauges like 25G, 27G, and 30G are common.
With a slim or straight pant, the “right” length is the top of the foot in front, and the top of the shoe in the back (if it is a shoe and not a boot). The goal is that the pant brushes the top of the foot and does not break or puddle, creating a clean, long line.
The smaller the gauge number, the larger the width or diameter. In contrast, the higher the number, the thinner the width. Needles that have a larger diameter also have thicker walls. As a result, they'll be more durable and stronger.
The larger the gauge number, the smaller the needle shaft.
These are regular-walled medical point needles. They are for intramuscular, subcutaneous, and other injections and are available in a wide range of gauges and lengths.
Although both can be used for machine embroidery, the main difference between embroidery and sewing machine needles is the shape of the eye and scarf. Machine embroidery needles have a longer eye and a specially-shaped scarf to suit the more delicate embroidery threads and not to break or fray them.
Universal Needles easily slip through weave of knits and woven fabric with rounded tip and tapered end. Size 80/12 is best suited for light weight fabrics.
Needles sizes #65/9 to #75/11 are your most popular size needles and work well with 60 and 40 weight threads. The larger the needle size, the larger the needle and needle eye. Larger size needles are necessary for some metallic and other thicker threads.
Triumph Flat Shank Needles #65/9
This point type is designed to make a clean penetration in woven materials. This point type and blade size have one of the smallest footprints for any embroidery-specific needle type. Not well-suited to use on knits.
Use a 90/14 needle for light- and medium-weight denim and a 100/16 for heavyweight denim.
