Best Midori MD Notebook for Work, Study, Journaling, and Daily Carry
A5 is the best Midori MD notebook for roomy work and study, A6 is best for light carry, B6 Slim is best for narrow portable notes, and Codex is best for high-volume journaling. If you are choosing the best Midori notebook by use case, start with how much writing space you need in one sitting and how often the notebook has to move with you. Canadian buyers comparing Midori MD A5, A6, B6 Slim, and Codex do not need to treat one size as universally better.

Work and meetings
For work, the safest recommendation is the MD Notebook [A5]. A5 gives you enough room to capture meeting context, decisions, action items, questions, and follow-up notes without forcing every thought into shorthand. If your notebook sits beside a laptop, on a desk, or next to printed documents, A5 feels like the most natural work size because it supports complete notes rather than fragments.
This matters because work notes usually need to be understood later. A quick list may be enough during the meeting, but the value of the notebook comes when you return to it at the end of the day or week. A5 gives you space to separate topics, leave room for updates, and mark what still needs attention.
B6 Slim can also work well for meetings when your notes are linear. If you mostly write dated entries, bullet points, call notes, or narrow task lists, the slimmer page can feel organized from the start. It is less suited to wide diagrams or side-by-side sections, but strong for people who prefer vertical structure.
A6 is better for quick work capture than full meeting notes. It fits short reminders, phone call notes, ideas, and portable lists. However, if your meetings regularly produce detailed decisions or multi-step follow-up, A6 may run out of useful page space quickly. Codex is usually more notebook than most work meetings require unless your work practice involves daily long-form reflection, project logs, or dated writing.
Study notes
For study notes, A5 is again the strongest starting point. Students and self-directed learners often need to combine lecture notes, reading summaries, vocabulary, examples, formulas, diagrams, questions, and review prompts. A5 gives enough room to organize these elements clearly. That is why it is often the best notebook for study notes among the Midori MD sizes covered here.
A good study notebook needs to help you retrieve information, not just record it. The extra page space in A5 makes it easier to create headings, indent supporting details, add small diagrams, or leave a margin for review. If you use active recall, you can reserve part of the page for prompts. If you summarize readings, you can separate the author’s argument from your interpretation.
B6 Slim can work for focused study sessions where notes are mostly sequential. It suits language vocabulary, reading logs, chapter summaries, and short concept lists. The narrow shape encourages concise writing, which can help when you are trying to avoid copying too much from a textbook or lecture. However, if you regularly draw charts, compare concepts side by side, or map larger topics, A5 will usually feel more flexible.
A6 is best for study support rather than primary notes. It can hold flashcard-style prompts, exam checklists, small reading goals, or quick questions to research later. Codex can be useful for a long course, thesis journal, research diary, or multi-month study project, but its value depends on whether you want a single high-volume book rather than separate notebooks by subject.
Journaling and long projects
For high-volume journaling, Codex is the clear recommendation. The MD Notebook [A5] Codex 1 Day 1 Page Dot Grid is built around a one-day-one-page style, making it a strong choice for people who want one notebook to hold a long sequence of daily entries. If you write often and do not want to switch books quickly, Codex is the format to compare first.
The main difference between Codex and a standard A5 notebook is not just size on the desk; it is the writing commitment. A standard A5 is excellent for flexible journaling, work notes, study notes, and project planning. Codex is more specifically appealing when your journaling habit is steady enough to benefit from many pages in one book. It suits daily reflections, project diaries, creative logs, wellness tracking, reading journals, or long-form personal notes.
The dot grid layout in the Codex version gives structure without forcing every page into lined writing. That can help if your journal pages vary from paragraphs to lists, logs, sketches, or trackers. Still, the best choice depends on how you write. If you journal only occasionally, a standard A5 may be simpler. If you want a smaller journal for brief entries, A6 may feel more approachable. If you like narrow dated logs, B6 Slim may provide a balanced middle ground.
For more detail on this comparison, the supporting guide Midori MD Codex vs Standard A5 Notebook is useful because it frames the choice around writing volume and format. That is the practical question: do you need one flexible notebook, or one larger-capacity notebook for sustained daily writing?
Daily carry
For daily carry, A6 is the most practical recommendation. A daily carry notebook should be easy to reach for quick notes, small lists, reminders, observations, and ideas. The goal is not to create the most spacious writing surface. The goal is to reduce friction so the notebook gets used. That is where A6 stands out as a notebook for daily carry.
A6 works especially well when entries are short: appointment notes, errands, a book recommendation, a phone number, a quick idea, or a few lines from a conversation. These are the notes that often disappear when your only notebook is too large for casual use. A smaller notebook can become the place where details are captured before they are forgotten.
The supporting article The Notebook That Left the Desk: Why A6 Notebooks Get Used More Than Bigger Ones makes this point from a use-pattern perspective: smaller notebooks often win because they are present when the note happens. That does not make A6 better for every task. It makes A6 better when the job is portable capture.
B6 Slim is the alternative if A6 feels too small but A5 feels too wide for daily notes. Its tall, narrow page suits lists, logs, and quick planning. It can be a strong everyday notebook for people who want more vertical writing space without moving all the way to A5. Choose A6 for brief capture. Choose B6 Slim for portable notes that need more structure.
How layout changes the recommendation
Size is only half the decision. Layout can change which Midori MD notebook feels right for your use case. A blank page gives the most freedom for sketches, mind maps, diagrams, or mixed writing. Lined pages support straightforward paragraphs and meeting notes. Grid pages help with alignment, tables, and structured study notes. Dot grid offers guidance while staying visually lighter than a full grid.
For work, lined or grid layouts are often easiest because they keep notes organized. If your meetings produce action items, timelines, or simple tables, grid can be useful. If your notes are mostly sentences and bullet points, lined may be enough. For study, grid and dot grid are strong choices because they support both writing and structure.
For journaling, the best layout depends on the style of entry. Long reflective writing may feel natural on lined pages. Mixed journaling with lists, trackers, small diagrams, or flexible sections may benefit from dot grid. Blank pages are best for people who dislike visible structure and want each spread to develop freely. For daily carry, simple layouts usually work best because the notebook needs to be quick, not complicated.
If layout is the part you are unsure about, the supporting Midori MD notebook layout guide is the most relevant next read. It compares blank, lined, grid, and dot grid from a practical writing perspective, which can help you choose the right version after you have chosen the right size.
Weight and page-count tradeoffs
The biggest tradeoff is simple: more page space and more pages usually mean more notebook, while lighter formats mean less room per entry. A5 gives generous writing space, but it is larger than A6 or B6 Slim. A6 is easier to choose for quick use, but its smaller pages limit how much you can write before turning the page. B6 Slim sits between those instincts, offering a narrow page that can feel more substantial than A6 while staying more compact than A5.
Codex changes the equation because it is for high-volume writing. It is the right choice when page count is part of the value. If you want a long journaling sequence, a daily log, or a project record in one book, the extra capacity is the point. If you want something for occasional notes, Codex may be more than you need.
The practical question is not “Which notebook is best?” but “Which limitation will bother me least?” If cramped pages bother you, choose A5. If carrying a larger notebook makes you less likely to use it, choose A6. If you want portable structure, choose B6 Slim. If changing notebooks too often interrupts a daily writing habit, choose Codex.
Where Canadian buyers can compare current listings
Canadian buyers should compare current Midori MD listings, available formats, and prices from a Canadian source before deciding. Availability can change, and the best choice is easier when you can see the A5, A6, B6 Slim, and Codex options together rather than evaluating each one in isolation. The supporting guide Where to Buy Midori Notebooks in Canada is written for this exact buying context.
When comparing listings, start with use case before layout or price. If the notebook is for work and study, look at A5 first. If it is for daily carry, compare A6 and B6 Slim. If it is for long-form journaling, compare Codex against standard A5. Then choose the layout that supports your writing style.
It also helps to think about whether you want one notebook for everything or different notebooks for different roles. A5 can serve as an all-purpose desk notebook. A6 can act as a capture notebook. B6 Slim can become a portable planner-style note space. Codex can hold a long journaling practice. Many buyers are deciding which writing role they need to fill first.
Conclusion
The best Midori notebook depends on the writing situation. Choose A5 for roomy work and study notes, A6 for light daily carry, B6 Slim for narrow portable notes, and Codex for high-volume journaling or long projects. If you want one default recommendation, A5 is the most flexible. If you want the notebook you are most likely to reach for on the move, A6 is the better starting point. If you want structure in a slimmer format, B6 Slim deserves a close look. If your priority is a sustained journal in one book, Codex is the strongest match.
