Standard Sizes of the Ink Cap
Our various ink cap sizes are considered standard sizes in the tattoo industry. The numbered cap dictates the size of the diameter in mm. So a number twelve ink cap will have a 12mm diameter. A number nine will have a 9mm diameter and so on. There are other suppliers that use simplified systems like Large, Medium and Small. Generally the small will be number 9. The medium is either a 12 or 15. The large is usually the 18.
