Is 21 or 22 needle smaller?
Unlike standard measurement systems, there is an inverse relationship for the gauge numbers and the size of needles. As the gauge number increases, the needle width gets narrower. For example, a 22g needle is thinner than a 21g.
Which is bigger 18 or 22 gauge needle?
IV needles are sized by gauges, and the smaller the gauge number, the bigger the needle will be. In this article and video, I’ll discuss the three most common IV gauge needles you’ll encounter as a nurse: 18 gauge, 20 gauge, and 22 gauge.

What are 22 gauge needles used for?
Intramuscular (IM) injections
The deltoid muscle is most often used as the site for IM injections in adults. Needle length is usually 1″–1½”, 22–25 gauge, but a longer or shorter needle may be needed depending on the patient’s weight.
What does 23 gauge needle mean?
The gauge refers to the inner measurement or opening of the needle. Needles are routinely available in a variety of gauge sizes, including 18, 21, 23, and 25 gauge, as shown in the image. The needle gauge becomes a consideration when the vein of the patient is narrow, fragile, or superficial.
What is a 26 gauge needle used for?
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. They have an oversized chrome plated luer lock hub.
What is an 18g needle used for?
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. They have an oversized chrome plated luer lock hub.
What is 20 gauge needle used for?
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.
Which is bigger 22 gauge or 20 gauge?
