The nib defines your whole fountain-pen writing experience. Same pen will perform completely different with different nib tips. Whether you are shopping for an elegant office signature pen, a calligraphy pen silver or a Comfort Grip Fountain Pen, nib selection matters a lot. Below we break down 5 common nib options: EF, F, M, Fude(Small), Fude(Large), including typical line width ranges, to help you match nib to your handwriting and usage.

EF (Extra-Fine)

- Typical line width: approximately 0.38–0.48 mm

- Pros: Fine lines, lower ink consumption, less bleed-through on regular paper.
- Notes: May show more paper texture; pair with smooth paper for a cleaner feel.
F (Fine)

- Typical line width: approximately 0.45–0.55 mm
- Most popular all-round beginner-friendly nib.
- Best for: daily school notes, office memos, general journal writing. The balanced line fits our Comfort Grip Fountain Pen for all-day comfortable writing.
