Various Types of Needles Used for Sewing Different Fabrics

Select the type of needle based on the textile construction (i.e knit vs woven), and the needle size is determined by the thickness of the thread and the weight of the fabric used for sewing.

There is two needle sizing system: American and European. American Needle sizes range from 8 to 19, and European sizes range from 60 to 120. Larger the number, the larger the blade of the needle.

Commonly used needles and their uses as below:

Needle Fabric
Sizes Description
Ball-point Knits 70/10     –
This needle has a medium tip that is slightly more rounded than a universal needle and passes between the fabric threads instead of piercing them. Ball-point needles ensure more even stitches on coarse and heavy knits and won’t damage spandex, interlocks, and other knits that snag or run easily.
Sharp/ Microtex Finely woven fabrics 60/8 –
These needles feature a narrow shaft and sharper point to pierce the threads of woven fabrics. Use for stitching smooth, finely woven fabrics, such as silk, chintz, lightweight faux suede, and microfiber fabrics. Because these needles enable perfectly straight stitching, they’re also ideal for heirloom stitching, topstitching, pintucks, and edge stitching.
Universal Knits or woven 60/8 –
The point is very slightly rounded for use on knits but sharp enough to pierce woven fabrics. These needles are available in the widest size range. Use when stitching Synthetic or natural woven knits.
Denim/ Jeans Heavy wovens and denim 70/10 –
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.
