Grommet and Eyelet Sizing Chart

Sizes for grommets are generally listed as a the measurement of the inside diameter (the hole). In the chart below we have provided exact measurements for inside diameter/outside diameter/depth. For size 12, we carry both size #12 and size #12L, both have same inside diameter but 12L is wider overall. We now carry size #15 grommets. See table below for dimensions.
