Guide to Fountain Pen Nibs - Understanding Nib Sizes and Thickness

Fountain pens are more than just writing tools; they are instruments that transform the act of writing into an art form. Central to the fountain pen experience is the nib – a delicate component that affects not only the aesthetics of your writing but also the comfort and flow of your strokes. In this guide, we will explore the nuances of fountain pen nib sizes, including #5, #6, #7, and #8, as well as delve into the distinction between nib size and nib thickness.

Nib Size: nib size is denoted by numbers #5, #6, #7, #8 and it determines the overall dimensions of the nib, influencing the pen's appearance and your writing experience. In fact, the number denotes the actual inner diameter of the metal nib. So a #6 nib has a 6mm inner diameter. Correspondingly, the plastic nib feed that the #6 nib goes on has a 6mm outer diameter.

Nib Thickness: Nib thickness refers to how wide or narrow the lines produced by the nib are. It is simply how wide the tip of the nib is. A finer nib will result in a thinner line, while a broader nib will produce a thicker line.

This is confusing! What is the Difference Between Fountain Pen Nib Size and Nib Thickness?

While nib size refers to the physical dimensions of the nib, nib thickness refers to the width of the line the nib creates when writing. Manufacturers often make a range of nib thicknesses for each nib size. So, for example, you might have a size #6 nib sold in fine, medium and thick nib thickness.

The important thing to understand is that fountain pens are made to accept a particular nib size. For example, the Jinhao x750 fountain pen requires a size #6 nib. Other nib sizes (#5, #7, #8) physically will not fit the pen. Once you know the nib size, you can buy a nib in that size in the thickness of your choice.

Note: to add to our confusion, manufacturers sometimes use a different naming convention for their nibs. For example, Jinhao describe the nib for their x450 fountain pen as “Jinhao nib #35”, which is the same as a nib size #6.

The Difference Between Fountain Pen Nib Sizes: #5, #6, #7, #8

Fountain pen nib sizes are often designated by numbers, such as #5, #6, #7, and #8. These numbers correspond to the physical dimensions of the nib, with #5 being the smallest in diameter and length. As a rough guide (remembering that nib size does not determine the line thickness):

#5 Nib Size: A #5 nib is typically smaller in size and is commonly found in slimmer pens. It tends to be used with finer nibs and produces a finer line, making it suitable for intricate writing or detailed sketches.

#6 Nib Size: A #6 nib is a popular size and offers a balanced writing experience. It's versatile enough for everyday writing while still accommodating a range of writing styles and nib thicknesses. They are comfortable to write with for extended periods of time. This nib is used in the popular Jinhao x750 and x450 pens sold at Skilltoyz. 

#7 Nib Size: A #7 nib is larger than #6 and is often favoured by those who appreciate a bolder, more expressive writing style. Associated with thicker nib thicknesses, it can produce thicker lines and is particularly useful for calligraphy or signatures.

#8 Nib Size: A #8 nib is among the larger nib sizes available. It offers a luxurious writing experience with broad, dramatic lines. This size is often chosen by those who want to make a statement with their writing.

What is the Most Common Fountain Pen Nib Size?

The most common fountain pen nib size is the medium (M) nib. This size strikes a balance between boldness and finesse, making it suitable for various writing styles and tasks. It's a versatile choice for daily writing needs. Medium nibs are comfortable to write with for extended periods of time.

What is the Standard Size of a Fountain Pen Nib?

While there isn't a universal standard size for fountain pen nibs, the medium (#6) nib is often considered a reference point. This size offers a comfortable experience for many writers and is frequently used as a starting point when exploring different nib sizes.

How Do I Know Which Nib Thickness I Need?

Choosing the right nib thickness depends on various factors:

Your handwriting: If you have small handwriting, you will need a finer nib (Fine or Extra Fine). If you have large handwriting, you can use a broader nib.

Personal Preference: Do you prefer thick, bold lines or fine elegant writing?

Writing Style: Consider whether you have a light or heavy hand when writing. Light writers may prefer finer nibs, while heavy writers might appreciate broader nibs.

Purpose: Determine if you'll be using the pen for everyday writing, calligraphy, or artistic endeavours. Different nib sizes suit different purposes.

The type of paper you use: If you use thin paper, you will need a finer nib to prevent ink from bleeding through. If you use thicker paper, you can use a broader nib.

Experiment with different nib sizes to find what feels most comfortable and suits your style. Try out pens with various nib sizes before making a decision.

What is the Difference Between EF and F Nib Size?

The difference between extra-fine (EF) and fine (F) nib sizes lies in the thickness of the line they create:

EF (Extra-Fine) Nib: An EF nib produces a very thin line, ideal for precise writing, intricate details, and small handwriting.

F (Fine) Nib: A fine nib creates a slightly thicker line compared to an EF nib. It strikes a balance between precision and smoothness, making it suitable for everyday writing. F nibs are a good all-around nib size that suit most people.

Conclusion

Understanding fountain pen nib sizes is essential for tailoring your writing experience to your preferences and needs. Whether you opt for a #5, #6, #7, or #8 nib, remember that both nib size and nib thickness play a role in shaping your writing style. Explore different nib sizes, thicknesses, and experiment with fine and broad lines. Discover the joy of expressing yourself through the art of writing.

Guide to Jinhao Ink Cartridge Sizes

Most Jinhao fountain pens can use an international sized ink cartridge with a bore size of 2.60mm. This is the only size of Jinhao ink cartridges we presently sell. However, I learned today that a few Jinhao fountain pens (including some of the 619 model) need ink cartridges with a bore size of 3.4mm. 

So the Jinhao ink cartridges we sell (bore size of 2.60mm) do not in fact fit all models of Jinhao fountain pens. 

Note 1: this also means the syringe converter for bottled ink is a different size in some Jinhao models.  
Note 2: the bore size is the inner diameter of the end of the cartridge/convertor.
