Download Nib width form - Version 2.0

* * * * - 3 Votes


This is an anonymously donated form for determining and checking nib widths, and will work for any kind of fountain pen nib, provided it is printed at 100 %, on a good quality paper, preferably with a laser jet printer on paper that is friendly to fountain pens.

The 100 % setting is very important in order to determine the nib width, both horizontal and down strokes, as accurately as possible. The line thicknesses for nib stroke comparison were created to very exacting standards, at exactly 100 %.

Have fun!

Thanks very much. This nib width sheet works very well, even to 5/100th of a millimetre. It's also fun to use: kind of an eye resolution test, I guess. Set scaling to none or to 100 % for a precise print. - JG

Thank You very much for this.

So, so ... Well, I tried it ...

It works, very clearly, but we must CAREFULLY (with a magnifying glass) to select paper. In Russia it is not trivial :-).

This would make more sense to me if it were to say this is medium, fine, etc, etc etc

The numbers really mean nothing to me at this point. I have pens I have purchased with no mention of what the nib size is. I was assuming this chart would do that until I saw only numbers and lines.

Ok after reading everyone's replies I assume I am supposed to make a line on the form I print out with the pen nib I want to check or......?


The problem is there is no standard for what is a F,M,B etc.

Each company does its own thing as to what each letter size actually is. 

Example, I measured the width of the tip of 3 pens with a dial caliper; Pilot Metro M, old Parker M, Lamy F.  All 3 measured the SAME, 0.028 inch wide.

And to make it worse, some companies have changed the definition over time.

Example, above I mention "old Parker" because I understand that the current Parkers use a different scale.  I have also been told that Lamy is the same, the older Lamy nibs are narrower that the current nibs of the same letter grade.

comes in hand when I've bought a pen without nib markings!  I can always eyeball it but, this is a much more credible witness and gets right to the point!

Thank you.

This is very helpful.

Tks for post.
