What Size Needles For Sewing Machine

What Size Needles for Sewing Machine
Sewing machines are quite tricky when it comes to finding the correct needle size to use. It requires a great deal of precision, common sense, and a good eye for detail. Poor needle selection can not only cause problems with your sewing projects, but it can also damage your sewing machine.
Different tools require different needles, and it’s important to understand the size and type of needles you should use when working with a sewing machine. In this article, we’ll explore the most important aspects of the right needle size for your sewing machine.

Importance of Using the Correct Needle

A correctly sized needle is important for two main reasons when it comes to sewing. First and foremost, needles come in different types and sizes to handle different types of fabric. Second, the size of the needle, the size of the eye, and the length of the needle determine the amount of thread that can be held while sewing.
If you choose the wrong needle size, it can lead to problems such as skipped stitches and broken threads. In addition, it could even cause fabric damage, such as skipped stitches, pucker marks, and even torn fabric.

Size and Class of Needles

The size of the needle is important when it comes to the type of fabric you are working with and the type of thread that you are using. The size of the needle is indicated by a number and a letter, such as 70/10. The first number (70) indicates the European size, while the second number (10) indicates the American size. The higher the number, the larger and thicker the needle.
Needles also come in different classes, including extra light duty needles, light duty needles, universal needles, and heavy-duty needles. Depending on the fabric you are working with and the type of thread you are using, you need to choose the appropriate needle class.

Type of Needles for Machines

Sewing machines require special needles that are designed to function properly with them. These needles have a flat back that allows them to move smoothly through the machine without causing any damage. Different machines require different sizes, so it is important to select the right size for your machine.
The most common needle sizes for sewing machines are 70/10, 80/12, 90/14, and 100/16. If you are unsure of the needle size that is right for your machine, you should consult the manual of your sewing machine.

Factors to Consider When Choosing Needles

When selecting a needle size for your sewing machine, you should consider the type of fabric you are working with and the type of thread you are using. If you are working with light or delicate fabrics, then a smaller needle size is recommended.
The type of thread you are using is also important to consider when selecting a needle size. If you are using a heavy thread, then a larger needle is recommended. Threads also come in different types, such as cotton, rayon, and polyester. The needle size you select should match the material and thread type you are using.

Properties of the Needle Points

The point of the needle also plays a role in selecting the proper needle size. Needles come with different point types, including sharp, universal, and ballpoint points. Different types of fabrics require different types of points.
Sharp points are great for woven fabrics, such as cotton and linen, as they make a clean hole in the fabric. Universal points are best for most woven fabrics, as well as many knit fabrics. Ballpoint needles are ideal for knit fabrics as they make a loop instead of a hole, which prevents the fabric from gathering.

Safety Tips

When working with a sewing machine, it is important to use the appropriate needle size and class to avoid damage to the fabric and your machine. It is also important to inspect the needle regularly and replace it when it is dull or worn. Dull and worn needles can cause skipped stitches, fabric damage, and even machine damage.
It is also important to keep spare needles of different sizes and classes on hand, as they can come in handy when you encounter different fabrics and threads. Additionally, always make sure to unplug your machine before putting in a new needle, as this can help to prevent injury.

Additional Factors to Consider

When selecting the needle size for your sewing machine, it is important to take into account the fabric, the thread, the point of the needle, and the size of the needle. Additionally, it is important to remember to use the correct needle class and to inspect and replace it regularly to ensure the best results and avoid fabric and machine damage.


To ensure the best possible results when sewing, it is important to select the correct needle size for your machine. This requires careful consideration of the type of fabric, the type of thread, the needle point, and the needle size. Additionally, inspect and replace your needles regularly to avoid machine and fabric damage.

For Which Fabrics Are Universal Needles Recommended?

Universal needles are recommended for use on woven fabrics and a wide range of knit materials. Universal needles are universally compatible and are suitable for most types of fabrics. They are designed to prevent skipped stitches and fabric damage and are typically great for general sewing.

When Should I Replace My Needle?

Needles should be inspected and replaced regularly to ensure the best possible results when sewing. If your needles are worn or dull, replace them right away as they can cause skipped stitches and fabric damage. In addition, it is important to unplug your machine before putting in a new needle, as this can help prevent injury.

What Is the Strongest Type of Needle?

Heavy-duty needles are the strongest type of needles and are designed to handle heavier fabrics, such as denim, leather, and canvas. They are thicker and more robust than other types of needles, and are made to avoid skipped stitches and fabric damage.

Are Sharps Needles Suitable for Knit Fabrics?

Sharp needles are not suitable for knit fabrics, as they tend to cut the fabric. The sharp points of the needles can create jagged holes in the fabric, leading to fabric damage and skipped stitches. Ballpoint needles are better suited for knit fabrics as they make a loop instead of a hole.
