Smaller gauge numbers indicate larger outer diameters. [4] Inner diameter depends on both gauge and wall thickness. The following chart shows nominal inner diameter and wall thickness for regular-wall needles. [4] [5] Thin-wall needles (not shown) have identical outer diameters but larger inner diameters for a given gauge.
An increasing French size corresponds to a larger external diameter. This is contrary to Birmingham gauge, where an increasing gauge corresponds to a smaller diameter needle. The French size is a measure of the outer diameter of a catheter (not internal drainage channel, or inner diameter). So, for example, if a two-way catheter of 20 Fr is ...
Various needle lengths are available for any given gauge. Needles in common medical use range from 7 gauge (the largest) to 34 (the smallest). 21-gauge needles are most commonly used for drawing blood for testing purposes, and 16- or 17-gauge needles are most commonly used for blood donation, as the larger luminal cross-sectional area results ...
A hook gauge is the most reliable way to determine the actual size of a tool. Even though most hooks and needles have metric sizing, tool dimensions vary slightly between different manufacturers. Non-metric sizing conventions also change over time. For instance, different sizing charts rate a 4.0mm hook as either a U.S. G/6 or an F/5. [2]
