All the time I find myself splitting pages into sections that are similar to common index card sizes.

Typically close to either 3x5 or 4x6. Depending on the notebook and size.

Based on how little I have used index cards over the years I find the whole thing weird and funny.

But there is something about that size that is perfect for a constrained collection of tasks that works really well for my brain.

For example, at the moment my a double spread in my full sized Travelers Notebook is divided into 8 blocks like this.

One has random captured impulses and thoughts. The other one has the start of a shopping list. And the first one has the tasks I’m currently working on.

Another part of it for me is that by splitting in vertical I use around 50% more of the paper surface compared to if I didn’t.

And of course it limits how much I have to move back and forth between pages.
