Sheaffer used a dial indicator nib gauge for measuring nib sizes. The nib was inserted into the gauge, and the size read off of the dial. A given size being nibs that fell within a given range. What is listed below were the ranges given on a gauge that I saw in the Sheaffer service center prior to being closed in March 2008.

Measurements are in thousandths of an inch.

XXF = 0.010 - 0.013
XF = 0.013 - 0.018
F = 0.018 - 0.025
M = 0.025 - 0.031
Broad* = 0.031 - 0.050
Stub = 0.038 - 0.050

*there was some overlap on the gauge. May be 0.035 - 0.050

That is very interesting. The variation between sizes as normal, is larger than I expected.
Was Sheaffer and Parker about the same width in nib size?
I don't seem to hear of any wars about it, over on General.

There are verbal wars going today, as to what is medium or fine or EF; involving one company that is a touch wider than "normal" (That uses dry inks) and another that is a bit narrower than "normal"(That uses wet inks). There for each meet in the middle.

Was/is Sheaffer inks, wet, dry or in the middle?

The real problem is not one company is larger or narrower than the other but the users are using the wrong inks and end up comparing cherries to pineapples.
Both have their place on a cocktail stick in a proper drink.

Due to Mauricio's improved definition of Super-flex, I try not use the term Easy Full Flex, but fail...sigh.

 

Semi-flex is an “almost” flex; not a ‘flex’ nib. It is great for regular writing with a touch of flair. It can give you some fancy; but it is not made for real fancy writing. For bit more of that get a maxi-semi-flex. Both spread tines 3X.  Those are not "Flex" nibs. 

 

Wider than Normal does not exist. Wider than Japanese does. Every company has it's very own standard + slop/tolerance. Developed from the users of it's pens and inks only; not the users or inks of other companies pens. The size you grind a nib to, is your standard only. Paper and ink matter to nib width. Thank god for 1/2 sizes or it would be boring.
