Search by Nib Size

List of pen nib sizes.

You can now search for our pens by nib size. Although this box is just an illustration, the one near the top left column of the vintage pens or pre-owned pens pages is live and will show you the way.

Size matters…at least when you’re writing and want to use a specific nib point.

Following the advice of my brilliant and beautiful fiancée, we’ve added a new way to search for pens on our site by virtue of the nib size and writing qualities.

Clicking on a blue letter is all you need to do to pull up all of our pens with the nib you want. You’ll still need to read the description to find out how wet, dry, smooth or scratchy a nib might be, but this new nib-search box will help you winnow down your options much more quickly. The only other detail to look for is whether the pen is a tweener pen—a fine-medium or a medium-broad, that sort of thing.

All of our vintage pens and preowned pens will get pulled up by nib together! Who knows what treasures you might find that you weren’t initially looking for! You can find the nib search box on the top of the left column on our home page, vintage pens pages and preowned pens pages.

In case you need help translating the letters into nib sizes, here’s our guide:

XF = Extra Fine
F = Fine
M = Medium
B = Broad
BB = Double Broad
Stub = Awesomeness
O = Oblique
SF = Semi-Flex
FLEXI = Flexible, somewhere in the vicinity of wet noodle
