Brush Pens: Small vs. Big. What’s the difference?

I’m going to walk you through the difference between a small pen and a big pen!


In actuality, when someone refers to the size of a brush pen, they are just referring to the size of the tip…a big one or a small one! It sounds pretty simple, but there is a bit of clarification needed.

So, what is the difference?

Let’s take a look at the two most popular small and big brush pens.

When I take the tops off of these pens, you can see there is a HUGE difference between the size of the tips.

The main differences between the two are the stroke thicknesses

Where the difference comes into play with these is if you’re practicing your calligraphy with specific workbooks (like mine, 😉).

Why the difference in workbooks?

If you tried to use a small pen in the big pen workbook, your downstroke would not be thick enough. And vice versa.

But alas, the pens that fall in the “in-between” range…

In the case of a pen that falls in between a big or small tip, I would suggest going for a big pen workbook because your stroke will be easier for you to control.

Same goes for anything bristley, that’s a bit harder to control, like this Micron pen or even just a paintbrush.

The best way to decide if it’s a big pen, is anything bigger than the Tombow Fudenosuke.


And that’s a wrap!
