Tip Sizes

Most fineliners come in several tip sizes that may range from a super-fine 0.03 mm to a bold 1 mm. This gives artists the flexibility to render meticulous detail and graphic punch depending on their needs. Other fineliners have less precise sizing, such as XS, S, F, and M, or come only in one or two sizes. These are suitable for art that doesn’t require as many different line widths as well as writing and journaling. Some lines also include larger bullet-tipped markers or brush pens filled with the same ink as the fineliners.

Several fineliners use an unintuitive naming scheme inherited from technical pens. The numbers on these pens, such as 0.03 or 0.8, express their relative tip size. They do not correspond to a millimeter measurement. A pen with the number 0.03 has a tip size similar to 0.15 mm, while a pen numbered as 0.8 is similar to a 0.5 mm tip size. You can check the millimeter tip size of each of these pens on their respective product pages on our website.
