Syringe needles are measured in gauge (G), with a higher gauge number indicating a smaller needle diameter. The smallest commonly used needle is 30G, suitable for very fine injections, while larger needles, like 18G, are used for drawing blood or administering thicker medications. Generally, the range of syringe needles goes from 18G (largest) to 30G (smallest), with various sizes in between for different medical applications.
