4. Why do we need so many notebook sizes?

Many notebook sizes are required to satisfy the needs of different users. Size varieties give users options when making a choice. Here are some more reasons why it is ideal to have many notebook sizes.

4.1 Suitable for different applications

Suitable For Different Applications
Suitable For Different Applications

We all need notebooks. For different things. Children need soft-cover notebooks for their school work; business people need hard-cover notebooks to enter their records; bookkeepers, accountants, and storekeepers use them to prepare their books of accounts; and so on and so forth. These are different applications that require different sizes. 

While a small size may be appropriate for a business person who doesn’t write down very much, a record keeper will require a large notebook because he writes down a lot of data. So different sizes are ideal for different applications.

4.2 Suitable for different people

Different sizes suit different people. Some people prefer large notebook sizes, while others prefer smaller sizes—it is all about user preference. It is a fact that notebook manufacturers produce according to customer demand for size.

4.3 To fit in some bags

Many people consider their bag sizes when shopping for notebooks. If their bags are too small, they will find it difficult to carry the notebook around. Bags have different sizes ranging from small, medium, and big sizes. While a big bag can accommodate a book of any size, a medium or small bag may not. This is especially true for school bags. Children’s bags range from small to medium; some notebooks will not fit into them because they are too big. 

4.4 Price differences

Another reason why we need different notebook sizes is that we all have different budgets. What one can afford may be too much for another buyer. Notebooks are priced differently, and one of the major determinants of price is size. By offering different sizes to buyers, manufacturers are providing different options so people can go for the ones they can afford.

5. Select Notebook size according to your needs

For backpacks, there is really no size requirement for notebooks because most notebooks will fit into the average backpack because backpacks are bigger. However, it is the needs of the user that will determine the type of notebook they use. While size may not be an issue for backpack users, weight does. Students may not care too much about the size because the more pages they have for school work, the better, but office workers may prefer lighter books with fewer pages.

Conclusion:

Notebook sizes vary based on the type and what they are designed for. Sizes also differ based on location too. Some notebooks are popular in some countries but largely unused in others. While the A series version is popular in English-speaking countries, the B series is popular in North America and many French-speaking countries. Before you make your pick, decide on what you want to use the notebook for. Your page requirement should also matter but note that notebooks with more pages weigh more than notebooks with fewer pages. Besides page numbers, page thickness also affects overall weight too, so bear this in mind.
