When we refer to the size of the grip, we are talking about the diameter of the support cylinder which is measured in mm.
The grip works by filling in the web space between your thumb and your index finger. Two people with hands with the same length fingers may use different sized grips depending on the thickness of their fingers as the person with thinner fingers has a bigger space to fill in order to provide support and they will need a bigger size grip.
- A typical primary school pupil will use a grip size in the mid 20s.
- A typical secondary school pupil will use a size around 28 to 32mm which will increase as they grow.
- An adult with small hands will use a size around 32 to 34mm. An adult with larger hands will use a size around 36 to 40mm.
On the size guide, the bigger circles represent the size of the support grip and the smaller circle represents the size of the pen shaft. In order to select the correct size support for your hand, you need to compare the size of an elongated circle formed by your thumb and index finger with the printed circles.
I find the 40mm grip comfortable because it’s giving gentle support when I hold the pen, and it's preventing my index finger and thumb from collapsing.
If I use a smaller 38mm grip, it still offers some support, but the grip is moving around more and it’s not as comfortable.
If I use a 42mm grip then it's still comfortable and provides support, but it's restricting the movement of my fingers more, and it slows down my writing. However, given the amount of support it does offer, I might choose this size if I needed maximum support.
