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

I think there are many people who are interested in a system planner but don't know the size .

Compared to a bound notebook (notebook type), it is difficult for beginners to understand because there is a size notation that I have never heard of.

A long time ago, planners were a staple tool for businessmen, but now they are used by a wide range of users, especially women.

There are a dizzying variety of types, and in fact , there are thousands of types of notebooks on the market, including those made by manufacturers and those made by individuals.

There are a wide variety of sizes as well as types, and each size has different ease of use, so it is true that many users are searching for which size is right for them .

That's one of the joys of using a planner, but in order to choose the one that's right for you, you first need to understand the size types.

In this article, we will explain the sizes of system notebooks that are distributed in Japan.

In addition, our shop handles Bibles, mini6, and M5 sizes.

[All types] List of sizes of system notebooks

The system notebook comes in 6 different sizes .

This size is the size of the special paper (refill) that is bound into the 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 A5 size notebook.

It's easy to understand if you imagine half of A4 copy paper. Because it is large enough to write a lot of text, it can be said to be a notebook for hard users and advanced users.

The A5 size is suitable for use as a mothership for information gathering, and I get the impression that many people go through several sizes before finally arriving at the A5 size .

In addition, A4 documents can be folded and stored, making it an easy-to-use size for business situations.

However, due to its size, the notebook itself is heavy and a burden to carry, making it a little inconvenient to carry around. Therefore, some users use it without carrying it around, such as by placing it on their desk at home or at work.

A5 size is recommended for those who have a clear purpose for use.

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

The name HB x WA5 is easy to understand once you understand its spelling.

  • Height (H) is bible (B)
  • Width (W) is (A5) size

In other words, it has a shape similar to a square , which is a combination of the Bible standard and the A5 standard, and the size was created based on the feedback of users who felt that the popular Bible was not wide enough.

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

On the other hand, because the size was developed as a proprietary standard, there are not as many types of refills as there are for A5 or Bible.

③Bible - Refill size: H170 x W95 (mm)

The Bible is the most popular and popular size of the system planner.

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

There is a wide variety of refills, and in addition to monthly and weekly schedules, there are also business card holders, to-do lists, rulers, etc., and they are available at many stationery stores and online shops.

The biggest advantage of having so many types is that you can easily customize your notebook to suit yourself.

Because there are many customizable options , the Bible size is recommended for first-time planner users 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 size is popular among women because it is a stylish size that allows you to carry your Bible smartly. Also, for men, it is sized to fit in a suit pocket. (*Depends on suit size)

Narrow is a unique size developed by KNOX, but many manufacturers now offer it.

There is also a type of refill that can be used horizontally instead of vertically, and it is also attractive that there are many ways to use it.

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

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

There are many types of refills, so it is attractive that there are many choices after purchase .

This size is also popular among women, but more and more men are using it as well. I feel that the number of users is increasing because various mini 6 refills are available from various companies and it is easy to post on SNS.

Mini 6 is recommended for people who prefer smaller size but still want to write well. It's an attractive size that allows you to use it however you like.

However, because it is compact, it may be difficult to use as a main notebook.

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

Micro 5 is the smallest size notebook. It is also called "M5" and uses a 5-hole binder .

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

In addition, there was a time when many manufacturers withdrew because it was not a major size, but now it has gained support from notebook users, including Ashford, which continued to sell it, and certain stationery brands have variations. It's in place.

Ring size - Number of refills

Next, an important point when choosing a system planner is the ring size of the binder.

Even notebooks of the same bible size have different link diameters depending on the manufacturer , so the following differences will occur depending on the size.

  • Thickness of notebook
  • design
  • Number of refills stored

Therefore, it is important to remember the ring diameter as well as the size of the system organizer.

When purchasing a system planner, if you know not only the size of the notebook, but also the ring diameter, you will be less likely to think you made a mistake after purchasing it.

By the way, the binder used at LETS STATIONERY GOODS is

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

We are hiring.

By the way, our system planner uses a binder made by Krause, which is a certified product from Germany that is recognized around the world.

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

We would be honored if the above information was helpful in choosing the size of your system planner.
