There are several factors which need to be considered in choosing the size of a needle to use for an injection or “shot”. They include such issues as:
• the type and viscosity of the medication
• the size and age of the patient
• the mobility status of the patient
• the desired absorption rate for the medication
In general for IM (intramuscular) injections you would use a 21 to 23 gauge needle 1 to 1.5 inches long for an adult.
(I use 1.25" to 1.5" in my quads)
Hope this helps
