Needle gauges are used to measure the thickness of a needle from its eye to

the tip of its point. The size of the needle is determined by the diameter of

the round section of the needle. The gauge indicates the size of a needle in

millimetres and is written as a number preceded by a point, e.g. 0.25mm is a

25 gauge needle. The higher the gauge number the finer the needle.

In medical and veterinary use, the size of needles that can be used depends on

the size of syringe and the medication to be injected. In size, they range

from a thick 16 gauge needle used to inject medicines into animals to a very

fine 30 gauge needle used to inject insulin in humans.

In sewing, needles come in different lengths with different eye sizes and

points to suit your type of stitching. The size of the needle is indicated by

a number then the letter either NM for Metric needles or NE for English

needles. An NM 80/12 needle is a fine needle for delicate fabrics such as

chiffon and voile and an NM 16/100 would be a thicker needle for heavier

fabrics.

Sharp needles are often used in embroidery and tapestry work, in this case the

needles come in various lengths and thickness. The needle gauge is a handy

tool for measuring the diameter of the needle to ensure that the needle is the

correct size for the intended purpose.

Many people use a needle gauge to measure how thick their thread is. To do

this, they lay the thread over the grooves and notches on the gauge and see

the notch that the thread lies in and read the corresponding millimetre size.

The thread size should match or be slightly thicker than the needle size.

A typical needle gauge is a round disc made of stainless steel with a range of

notches and grooves along its circumference. As the needle gauge is round, it

can measure large or small needles as it can rotate to access the needle's tip.

Needle gauges are a convenient and accurate way of measuring the thickness of

needles and thread and ensuring the correct needle is chosen for the job at

hand. They are useful both within the medical and the sewing community, as

well as others who may require the use of needles and thread, such as

leatherworkers, beaders and jewellers. Investing in a needle gauge is an

important and useful tool for both domestic and commercial use.
