Fountain Pen Guide: Nib Types and Ink Compatibility

Elevate Your Writing: Choosing the Right Fountain Pen and Ink

Fountain pens transform writing from a mundane task into a pleasurable experience, but understanding nib types and ink compatibility is essential for getting started. As a pen enthusiast who’s tested hundreds of fountain pens, I’ll help you navigate the world of nib sizes, ink types, and pen maintenance. The right fountain pen can make your handwriting more elegant while being surprisingly practical for everyday use.

Nib Sizes and Writing Characteristics

Nib size dramatically affects your writing experience:

• Extra fine (EF): Precise lines ideal for small handwriting and detailed work
• Fine (F): Versatile for everyday writing and note-taking
• Medium (M): Smooth writing with visible line variation
• Broad (B): Bold lines that showcase ink properties and shading

In my testing, medium nibs provided the best balance of smoothness and practicality for most users new to fountain pens.

Ink Compatibility and Maintenance

Proper ink selection ensures optimal performance:

• Cartridge vs converter: Pre-filled convenience vs ink variety and cost savings
• Ink properties: Dye-based for easy cleaning, pigment-based for permanence
• Cleaning frequency: Regular maintenance prevents clogging and hard starts
• Paper compatibility: Some inks work better on specific paper types

Converter systems offered the most flexibility and lowest long-term cost in my usage analysis.
