Oops. #RabbitHole. #兎の穴
In 2018, I decided to #design a new #PersonalOrganizer format, in the hopes of slightly reducing the size from a typical Personal (95 mm x 171 mm). I have long used a 5 mm ruling standard for my #Filofax, so for the new format, I used a 12 pt ruling (~4.233 mm), the smallest I think is practical for Latin scripts.
Taking into account the size of US currency and checks, I settled on a page size of 237 pt x 438 pt, or about 83.6 mm x 154.5 mm.
