Do you want to use measurement layouts from Bullet Everything, but you don’t have the Leuchhturm 1917 A5 notebook these are measured with?
I’ve come up with a converter that should help you out.
Fill in the following form with the size of your notebook in squares.
If your notebook is a different size than the one I use, the spacing will be different as well. (I space most of my boxes 1 square apart. To find a comparison for spacing, type in 1 & 1 in the box size after typing in your notebook measurements.)
Then, if you are looking at a measurement layout from Bullet Everything, type in the width and height for what box size you want to convert.
It’s a good idea to print out the layout and you can mark off my box size and replace it with your own.
