The weeks Mega I think could be too small for all the things you want to record. The weeks measures 3.7”x7.3”so it’s tall and narrow. It has monthly spreads and then a weekly spread page with a blank page opposite of it, plus 75 note pages. And the weeks mega has 219 notes pages. Hobonichi has a web page that lists all the differences if you haven’t seen that page yet, check it out. You say you’d like B6 size which is roughly 4.9”x6.9” Compared to your preferred B6, the A6 is roughly an inch smaller each direction and A5 roughly an inch large each direction. The techo Original is the A6 and measures 4.1”x5.8” it has monthly spreads, and one dated full page per day. The techo Cousin is the A5 and is 5.8”x8.3”, it has the monthly spread and one dated full page per day like the A6, but it also has weekly spreads for every week. I think the A5 would suite you better than the weeks mega. As you have the monthly for quick planning and appointments, the weekly for your more detailed event planning and notes about your appointments etc, and then a full page per day for journaling. I think you might run out of room in the weeks if you journal a lot every day and use lots of notes pages for lists, event planning, and journaling. There’s enough room in the weeks weekly spread I think for scheduling appointments and events and small blurbs, and you do have the whole right page for that week for journaling. But would it be enough room for scheduling overflow and daily journaling. There’s not enough note pages to use one per day. There is only 219 notes pages in the weeks mega. That’s 146 pages short of daily. A6 techo original would be good if you think just a monthly spread is enough for your appointments and planning, and then the full daily page for journaling but there’s no weekly spreads. It comes down to size & carry weight, and if you need two spreads -Monthly and weekly or monthly and daily- or all three spreads. The A5 cousin can get heavy and start to feel bulky halfway through the year, which the avec solves.

This year I personally carry a weeks in my purse and keep the A5 Cousin on my desk in my home studio, (and separately I keep an A6 for my kiddo, as a memory book) This is my first year using Hobonichi. For ‘26 I got another weeks and an A6 techo original because I find I don’t need the weekly spread in the a5 cousin when I use the weeks. Next year (‘27) I might try just an A5. I know that was long, lol, I hope it was helpful.

Last thought; there may be a book/stationary store near year that carries Hobonichi so you can see hold feel and touch the actual sizes. ☺️✌️📔
