This is the Deep Indigo one, 21 x 30cm, effectively A4, ruled at 7mm. This is a desk and studio size. It will go in a bag, but it is not pretending to be pocketable, and the trade is that you get a full page to think on. The cover reads as a dark blue that reads almost black until light hits it, and behind it sit 80 sheets of 140gsm acid free paper that will take a fountain pen without complaining. The one you spread out on, in a colour picked for people who want the discipline of a black notebook with a pulse in it.

What 7mm ruling actually gives you

Plenty of notebooks rule at 6mm, which is why handwriting ends up looking squashed in them. Seven gives it room to breathe without turning the page into mostly empty space, and it is the spacing that suits an italic nib or a brush pen rather than fighting one.

Reach for ruling when you are writing rather than drawing. Daily pages, interview notes, study notes, long form thinking, anything that runs top to bottom. At 21 x 30cm you get a diagram and its notes side by side, which is the part people forget to think about until they are living with the book.
