A quick no brainer guide in choosing nib sizes in an overly complicated fountain pen world:

• If you write small, go with an Extra Fine.
• For the normal writer, Fine is the most popular.
• If you tend to lean on a bigger font, Medium will be perfect.
• Broad is for statements!! Sign a check in Broad, write a header in Broad, do some coloring/shading in Broad.
• Stub nibs are italic in writing style (great for writing in special cards or invitations).
