What Size Sewing Needle For Leather? Expert Answer!


The size of sewing needle you need for leather will depend on the thickness of the leather you are working with. For general use, a size 90/14 or 100/16 needle is a good choice. These needles are strong enough to pierce leather without damaging it, but they are not so thick that they will make it difficult to pull the needle through.

If you are working with thicker leather, you may need to use a larger needle, such as a size 110/18 or 120/19 needle. If you are working with thinner leather, you may be able to use a smaller needle, such as a size 80/12 needle.

Let’s see the general guide to the size of sewing needle you should use for different thicknesses of leather:

  • Thin leather (less than 1/8 inch): Size 80/12 or 90/14 needle
  • Medium leather (1/8 inch to 1/4 inch): Size 100/16 or 110/18 needle
  • Thick leather (more than 1/4 inch): Size 120/19 or 130/21 needle

It is also important to choose a needle that is specifically designed for leather. Leather needles have a triangular point that helps them to pierce leather without tearing it.

If you are unsure what size needle to use, it is always better to start with a smaller needle and work your way up to a larger needle if needed.

It is also helpful to test the needle on a piece of scrap leather before starting your project.

  • Medium-weight leather (4 oz to 7 oz): For leathers that fall within this thickness range, a needle size between 12 and 16 would work well.
