In a fountain pen that aspires to excellence, all the materials have to be excellent: the body, the clip, the cap, the charging system, the projections, the case... But if there is one element that makes the difference, that is the nib.
The point or measure is perhaps the characteristic that will most affect the type of writing. It refers to the width of the nib, which determines the width of the stroke it provides.
Which nib point to choose will depend on its intended use and personal preference. The smallest ones are indicated for daily use and for amateurs with small print, while the larger dots create a wider and abundant line of ink, which allows you to better enjoy certain qualities of the ink by appreciating a certain variation in its flow in the strokes. Obviously the resulting letter, for its correct definition, is larger.
In the following picture, you can see the differences between a Platinum Ulta-Extra-fine nib and a Platinum Music nib.
