✒️ Understanding Fountain Pen Nib Sizes: Fine, Medium, Broad and Beyond

When it comes to fountain pens, one of the most important choices you’ll make is the nib size. This small but mighty component affects everything from how your writing looks to how it feels. Whether you're a casual note-taker or a calligraphy enthusiast, understanding the differences between nib sizes can transform your writing experience.

🔹 Fine (F) Nibs

Fine nibs produce a thin, crisp line and are often favored by those with small handwriting or who write on standard office paper.

• Line Width: Approximately 0.4mm–0.6mm

• Best For: Detailed writing, note-taking, precision

• Feel: Less ink flow, slightly more feedback on the page

  
  

🔸 Medium (M) Nibs

The medium nib is the most popular and versatile option. It provides a smooth writing experience and balanced line width.

• Line Width: Around 0.6mm–0.8mm

• Best For: Everyday writing, journaling, general use

• Feel: Smooth flow, comfortable for long sessions

  
  

🔶 Broad (B) Nibs

Broad nibs lay down a wider, wetter line, perfect for making bold statements or showcasing ink shading.

• Line Width: Roughly 0.9mm–1.1mm

• Best For: Signatures, expressive writing, ink lovers

• Feel: Generous ink flow, very smooth

  
  

✍️ Extra-Fine (EF/XF) Nibs

Extra-fine nibs offer the thinnest line, ideal for precision writing and small grid paper.

• Line Width: Around 0.3mm–0.4mm

• Best For: Technical writing, planners, minimal bleed-through

• Feel: Slightly scratchy for some, but very precise

  
  

🖋️ Italic & Stub Nibs

These are specialty nibs used for calligraphy or decorative writing. Italic nibs have sharp edges, while stub nibs are more rounded.

• Line Variation: Vertical strokes are thick, horizontal strokes are thin

• Best For: Calligraphy, headings, artistic writing

• Feel: Requires practice, unique character

• Small, neat handwriting? Try Fine or Extra-Fine.
