How to choose the best one from a list of all sizes of system notebook

I'm sure there are many people who are interested in system organizers but aren't quite sure what size to get .

Compared to bound diaries (notebook type), there are size notations that you may not have heard of, which can make it difficult for beginners to understand.

A long time ago, system organizers were a standard tool used by businessmen, but now they are used by a wide range of users, especially women.

The variety is dizzying; in fact, there are thousands of different types of system organizers on the market, including those made by manufacturers and privately produced items.

There is a wide range of sizes and types available, and each size has different ease of use, so many users find themselves trying to find which size is best for them .

That's one of the joys of using a system planner, but to choose one that's right for you, you first need to understand the different sizes available.

In this article, we will explain the sizes of system organizers available in Japan.

Our shop carries Bible, mini6, and M5 sizes.

[All types] System planner size list

The system notebook comes in six different sizes .

This size is for the special paper (refill) that is bound into a ring binder, so the system notebook itself will be one size larger.

*There may be an error of 1 to 2 mm depending on the manufacturer.

① A5 - Refill size: H210 x W148 (mm)

The largest system notebook size is A5 .

It's easier to understand if you imagine it as half an A4 sheet of copy paper. Because it is a size that allows you to write a lot of text, it can also be said to be a system organizer for heavy users and advanced users.

The A5 size is suitable for use as a mother ship for gathering information, and I get the impression that many people try several different sizes before finally settling on the A5 size .

In addition, since you can fold and store A4 documents, it is a convenient size for business situations.

However, due to its size, the planner itself is heavy and it is a little inconvenient to carry around . For this reason, some users do not carry it around with them, but just keep it on their desk at home or at work.

The A5 size is recommended for those who have a clear purpose for using it.

② HB x WA5 - Refill size: H170 x W148 (mm)

The name HB x WA5 is easy once you understand what the spelling means.

Height (H) is Bible (B)
Width (W) is (A5) size

In other words, it has a shape close to a square that combines the Bible standard and the A5 standard, and this size was created in response to feedback from users who felt that popular Bibles were not wide enough.

Ashford released this model as its own proprietary standard in 2010, and it has remained popular among some users ever since.

On the other hand, because it is a size created as a unique standard, there are fewer types of refills available compared to A5 or Bible.

③Bible - Refill size: H170 x W95 (mm)

The most popular and well-known size of system organizer is the Bible.

It is called the Bible because it is based on the size of the Bible, and is the most common size for a system organizer.

There is a wide variety of refills available, including monthly and weekly schedules, as well as business card holders, to-do lists, rulers, and more. They are widely available at many stationery stores and online shops.

The biggest advantage of having so many varieties is that you can easily customize your planner to suit your own tastes.

The Bible size offers a wide range of customization options , making it a great choice for those using a system organizer for the first time or as a gift.

④Narrow- Refill size: H170 x W80 (mm)

Narrow is a slim size that combines the height of a Bible and the width of a Mini 6.

This is a popular size among women because it is a stylish size that allows you to carry the Bible smartly. For men, it is also a size that fits in a suit pocket. (*Depending on the suit size)

Narrow is a unique size developed by KNOX, but is now available from many manufacturers.

There are also refills that can be used horizontally instead of vertically, which gives them a variety of uses.

⑤Mini 6 - Refill size: H126 x W80 (mm)

The second most popular size after the Bible size is the Mini 6.

There is a wide variety of refills available, so you have plenty of options to choose from after you purchase .

This size is also popular among women, but the number of men using it is increasing. This is probably because various companies are offering various mini 6 refills, and because they look good on social media.

The Mini 6 is recommended for people who prefer something smaller but still want to write clearly. It's an attractive size that allows you to use it freely and in your own way.

However, because it is compact, the size may be a bit too large to use as your main notebook.

⑥Micro 5 - Refill size: H105 x W62 (mm)

The smallest size of system organizer is the Micro5, also known as the M5 , and uses a 5-hole binder .

It's a minimalist notebook that's a little narrower than A7 and about the size of a business card (91 x 55mm), so I get the impression that many people use it to take quick notes or as a substitute for a jotter.

Also, because it was not a common size, there was a time when many manufacturers withdrew from the market, but now, thanks to support from planner users, led by Ashford, which continues to sell it, certain stationery brands offer a variety of them.

Ring size - Refill capacity

The next important point to consider when choosing a system organizer is the binder ring size.

Even if the planners are the same Bible size , the link diameter varies depending on the manufacturer , so there will be differences depending on the size, as follows:

Thickness of the notebook
design
Refill storage capacity

Therefore, along with the different sizes of your system planner, you should also remember information about the ring diameters.

When purchasing a system notebook, if you know not only the size of the notebook but also the size of the rings, you will be less likely to regret your purchase afterwards.

By the way, the binders we use at LETS STATIONERY GOODS are

Bible size: 20mm ring diameter
Mini 6: 13mm ring diameter

We have adopted the following.

By the way, our system organizers use binders made by Krause, a German company that is recognized worldwide.

The smoothness of opening and closing of binders varies greatly depending on the manufacturer, so we recommend choosing a product from a manufacturer that uses sturdy binders.
