Fountain pen nib size has a major impact on how your pen writes. The nib controls line width, ink flow, smoothness, and overall writing feel, so choosing the right size can make your fountain pen more comfortable and enjoyable to use.
If you are shopping for fountain pens, understanding nib sizes will help you choose a pen that matches your handwriting, paper, and daily writing needs.
What Is a Fountain Pen Nib?
The nib is the metal tip of a fountain pen that touches the paper and controls how ink flows onto the page. Nibs come in different sizes, shapes, and materials, each creating a different writing experience.

Common Fountain Pen Nib Sizes
Extra Fine Nib
An extra fine nib creates a very thin line, making it ideal for small handwriting, planners, margin notes, and detailed work. Extra fine nibs are also useful for writers who prefer less ink on the page.
Fine Nib
A fine nib is one of the most popular choices for everyday writing. It provides good control while still offering a smooth fountain pen experience. Fine nibs work well for notes, journals, and general handwriting.
Medium Nib
A medium nib produces a slightly wider line and usually feels smoother than finer nibs. It is a good choice for writers who want a balanced writing experience with more ink flow and visibility.
Broad Nib
A broad nib creates a bold line with more ink on the page. Broad nibs are often preferred for signatures, expressive writing, and showing off ink color, shading, and sheen.
Stub and Italic Nibs
Stub and italic nibs create line variation by producing wider downstrokes and thinner cross-strokes. These nibs are popular for calligraphy-inspired writing and users who want more character in their handwriting.
Fine vs Medium Fountain Pen Nib
Fine and medium nibs are the most common choices for everyday writing. A fine nib offers more precision and uses less ink, while a medium nib provides smoother flow and a bolder line.
