Midori MD Notebook Covers: Which Cover Fits A5, A6, B6 Slim, and Codex?
Unsayable lists separate clear covers for the standard Midori MD Notebook A5 and the thicker Midori MD Codex A5, while dedicated A6 and B6 Slim covers are not confirmed in the current Unsayable MD collection. If you are buying in Canada and need the safest fit, treat the standard A5 notebook and the A5 Codex as two different cover decisions. The primary option for a regular A5 MD Notebook is the MD Notebook Cover [A5] Clear. For the thicker Codex format, check the dedicated Midori Codex cover rather than assuming the regular A5 cover will stretch to fit.
| Notebook format | Cover status at Unsayable | What to buy or verify |
|---|---|---|
| Standard Midori MD A5 | Confirmed separate A5 clear cover listing | Use the MD Notebook Cover [A5] Clear |
| Midori MD Codex A5 | Confirmed separate Codex cover listing | Use the dedicated Midori Codex cover |
| Midori MD A6 | Dedicated cover not confirmed in the current collection | Verify the current MD Product collection before ordering |
| Midori MD B6 Slim | Dedicated cover not confirmed in the current collection | Do not substitute an A5 cover; verify dimensions and current listings first |
Why A5 page size does not mean one cover fits both A5 books
The most common mistake with a Midori notebook cover is assuming page size alone decides compatibility. A5 tells you the approximate page footprint, but not the book’s thickness, spine depth, cover wrap, or how much material the clear sleeve needs to close cleanly. That distinction matters most when comparing the standard Midori MD Notebook A5 with the Midori MD Codex A5.
Both are part of the Midori MD world, and both may be described as A5 notebooks, but the Codex is built around a much larger page count. A cover made for a slimmer standard A5 notebook is not automatically appropriate for a one-day-one-page Codex. Even if height and width appear close, the cover must travel around the spine and accommodate the extra book block.
That is why Unsayable’s current listings should be read carefully: there is a standard A5 clear cover and a separate Codex clear cover. For a buyer choosing the correct MD notebook cover, that separation is the key signal. The safer interpretation is not “A5 fits A5.” It is “standard A5 and A5 Codex require their own cover listings.”
This matters for Canadian buyers ordering online, where the product page has to stand in for physically testing the fit. Match the exact notebook format to the exact cover listing before checking out. If you already own the notebook, confirm whether it is the regular A5 or the Codex before adding an A5 notebook cover to your cart.
Standard A5 clear cover
For the regular Midori MD Notebook A5, the primary destination is the MD Notebook Cover [A5] Clear. This is the listing to use when your notebook is the standard A5 MD Notebook rather than the thicker Codex edition. In practical terms, this is the straightforward answer for shoppers searching for a Midori notebook cover for the classic A5 size.
A clear cover protects the notebook while preserving the simple MD look. Because Midori MD notebooks are known for restrained design, a transparent cover adds a practical layer without making the notebook visually loud. The important point is fit. The listing title identifies this as the A5 clear cover, so it should be treated as the match for the standard A5 notebook format.
If your goal is to buy one MD notebook cover and avoid second-guessing, start by checking the notebook title. If it says Midori MD Notebook A5 and does not say Codex, one day one page, or another thicker variant, the standard A5 cover is the relevant cover to consider. If the notebook is being purchased from the same MD collection, compare exact product names before checkout rather than relying on a photo or general A5 wording.
This also matters if you are buying a cover as a gift. Many people know the recipient uses “an A5 Midori,” but that phrase can hide the most important detail. A standard A5 notebook and a Codex are not the same cover problem. If you are uncertain, ask whether the notebook is the regular MD Notebook A5 or the thicker Codex.
For SEO searches, terms like Midori notebook cover, MD notebook cover, and A5 notebook cover may all lead to similar-looking results. Do not let the search term make the decision for you. For the standard A5 MD Notebook, the relevant Unsayable destination is the MD Notebook Cover [A5] Clear.
Dedicated Codex clear cover
The Midori MD Codex needs separate attention because it is not just another standard A5 notebook. The Codex format is thicker, and that thickness changes cover compatibility. Unsayable lists a dedicated Midori Codex cover, which is the important distinction for anyone buying a Midori Codex cover in Canada.
If you are considering the Codex because you want a substantial daily notebook, planner-like writing space, or a one-day-one-page format, do not add the regular A5 clear cover by habit. The Codex may share the A5 page category, but the cover must account for the deeper book block. Use the Codex-specific listing when the notebook itself is the MD Notebook A5 Codex 1 Day 1 Page format.
The difference is easy to miss because online stores often display products in grids where names are shortened or visually similar. A shopper may see “A5,” “clear,” and “MD Notebook Cover” and assume the first A5 cover is correct. For the Codex, pause and look for Codex wording in the cover listing. If the cover title identifies the Codex version, that is the safer match.
Unsayable also has a related guide comparing the two A5 formats: Midori MD Codex vs Standard A5 Notebook. That guide is useful if you are still deciding between the slimmer standard A5 and the thicker Codex before choosing a cover. First choose the notebook format. Then choose the cover designed for that format.
The practical rule is simple: if your notebook is Codex, buy the Codex cover. If your notebook is the standard A5 MD Notebook, buy the standard A5 clear cover. Do not treat the regular A5 cover as a universal solution for all A5-labeled MD books.
What to verify for A6 and B6 Slim
For A6 and B6 Slim shoppers, the current compatibility answer is more cautious. Dedicated A6 and B6 Slim covers are not confirmed in the current Unsayable MD collection based on the provided collection information. That does not mean Midori has never made covers in those sizes, and it does not mean future inventory will never change. It means you should not assume Unsayable currently has a dedicated cover listing for those formats unless you can see one in the live MD Product collection.
This caution is especially important for B6 Slim. B6 Slim is not a smaller A5 in any practical cover sense. It has a different footprint and proportion. An A5 notebook cover will not become a B6 Slim cover just because both are notebooks from the same brand family. If you are buying the Midori MD Notebook B6 Slim, verify whether a B6 Slim cover is separately listed before ordering accessories.
A6 needs the same discipline. A6 notebooks are valued because they are compact and easy to carry, but that compactness also means the cover has to be size-specific. A loose A5 cover would be far too large, and an improvised fit defeats the point of buying a clean MD notebook cover. If you are choosing A6 because you want something portable, read Unsayable’s related article, The Notebook That Left the Desk: Why A6 Notebooks Get Used More Than Bigger Ones, then return to the product collection to confirm current accessory availability.
For both A6 and B6 Slim, separate notebook availability from cover availability. A notebook can be available even when its matching cover is not listed. Do not infer one from the other. If the collection shows the notebook but not the matching cover, buy the notebook only if you are comfortable using it without that cover or waiting until a confirmed matching accessory appears.
How to check dimensions and thickness before ordering
Before buying any Midori notebook cover, check three things: the notebook format, the cover title, and whether the notebook is a standard or high-page-count version. The format tells you the height and width family. The cover title tells you the intended compatibility. The thickness tells you whether a same-page-size assumption could still fail.
Start with the notebook name. “A5” is not enough if the notebook might be Codex. Look for words such as Codex, 1 Day 1 Page, dot grid, or wording that suggests a thicker book. If the notebook is the standard A5 MD Notebook, the MD Notebook Cover [A5] Clear is the listing to review. If it is the Codex, use the dedicated Midori Codex cover.
Next, compare the cover title to the notebook title. The safest match is exact format language. Standard A5 cover for standard A5 notebook. Codex cover for Codex notebook. If the cover title does not name your notebook size or format, do not treat it as confirmed. This is particularly important for A6 and B6 Slim because dedicated covers are not confirmed in the current collection information.
Then consider thickness. A notebook cover has to wrap around the front, spine, and back. The thicker the notebook, the more cover material is needed across the spine. Two notebooks can share a page size while requiring different cover dimensions once closed. The Codex example proves the point: it needs its own cover listing because the book is not simply a standard A5 with a different label.
If you are ordering from Canada and trying to reduce returns or delays, use current product pages rather than memory, screenshots, or old search results. Inventory and collection pages can change. The current MD Product collection is the place to confirm what Unsayable is actually listing now. If a matching cover is not present, treat compatibility as unconfirmed rather than substituting a similar-looking cover.
Related Midori buying guides
If you are still choosing the notebook itself, start with the A5 comparison guide: Midori MD Codex vs Standard A5 Notebook. It is the most relevant supporting read because cover compatibility depends directly on whether you choose the standard A5 or the Codex. The cover decision becomes easier once that notebook decision is clear.
If you are considering a smaller notebook, read The Notebook That Left the Desk: Why A6 Notebooks Get Used More Than Bigger Ones. It explains why A6 appeals to people who want a notebook that leaves the desk, but it should not be used as proof of cover availability. After reading it, still check the current collection for a confirmed A6 cover listing.
For broader purchase planning, Unsayable’s Where to Buy Midori Notebooks in Canada guide is useful for Canadian shoppers comparing availability, shipping, and product selection. Use it alongside the current product pages, especially if you are buying a notebook and cover together.
Finally, the MD Product collection is the restrained place to browse current MD items. It is also where you should verify whether any A6 or B6 Slim accessory listings have been added since this compatibility summary was prepared.
Conclusion
The correct Midori notebook cover depends on the exact notebook format, not just the broad A5, A6, or B6 Slim label. For a standard Midori MD A5 notebook, use the MD Notebook Cover [A5] Clear. For the thicker A5 Codex, use the dedicated Midori Codex cover. For A6 and B6 Slim, dedicated covers are not confirmed in the current Unsayable collection information, so verify the live listings before adding accessories to your order.
If you want to browse the current MD selection without guessing from old product names, check Unsayable’s MD Product collection and match each notebook to a clearly named cover before ordering.
