The A-series is the most popular paper size standard and is widely used in Indonesia, especially for office documents, schools, and printing needs. The sizes range from large formats like A4 to very small ones like A7, each with its own specific applications.

A4 Paper

This paper measures 210 mm × 297 mm and is widely used for office documents, reports, printed materials, and seminar workbooks. A4-sized books or notebooks provide ample writing space, making them ideal for detailed note-taking or diagrams during intensive training sessions and workshops.

A5 Paper

Measuring 148 mm × 210 mm, A5 is a popular choice for seminars and corporate events because it is more compact than A4 while still providing a comfortable writing experience. A5 notebooks are easy to carry, look professional, and are commonly used as event souvenirs due to their convenient size.

A6 Paper

At 105 mm × 148 mm, A6 falls under the pocket notebook category. This size is very practical to carry anywhere and is suitable as a souvenir for large-scale events. Although small, it still provides enough space for daily notes, quick memos, or short ideas.

A7 Paper

Measuring 74 mm × 105 mm, A7 is considered a mini notebook size typically used for quick notes such as reminders, shopping lists, or short to-do lists. In seminars or events, this size is often included as an additional bonus in goodie bags because it is light, simple, and easy to customize.

2. B-Series Paper Sizes

B5 Paper

This size, 176 mm × 250 mm, is widely used for training workbooks, professional modules, journals, and premium reading books. B5 offers more writing space than A5 while being easier to handle than A4, making it highly versatile for events that require high-quality printed materials.

B6 Paper

Measuring 125 mm × 176 mm, B6 is often used for premium agendas, personal journals, or small novels. In corporate event settings, this size is ideal for exclusive gifts or corporate merchandise due to its elegant and compact appearance.

F4 measures 210 mm × 330 mm, making it longer than A4. It is widely used for administrative needs such as legal documents, archives, and forms. For seminars or workshops, F4 is often used for training materials filled with tables or forms that require extra space.
 

4. Popular Notebook Sizes in the Market

Aside from ISO standard sizes, many notebooks use flexible commercial dimensions tailored for event needs.

A4 Notebook

A4 notebooks provide wider pages and more space for writing extensive material. They are commonly used in technical training or workshops that require detailed notes and large drawing areas such as brainstorming, tables, or mind-mapping.

Standard Indonesian school notebooks typically measure around 165 mm × 210 mm with page counts such as 38, 58, or 80 sheets. This type of notebook is popular for educational events, casual seminars, or CSR programs because it is economical and easy to distribute in large quantities.
