Notebook or diary: how to choose the right format for writing, planning or drawing

Choosing a notebook or diary isn’t just about comparing a cover or a colour. Between the undated planner, the notebook, the sketchbook and the everyday office stationery, the format, paper and binding all directly affect how comfortable it is to use and how long it lasts.

Some disappointing purchases are actually quite predictable. Here are the main pitfalls to avoid before you fill your basket.

Common pitfalls when buying

• Relying only on looks: a pretty cover doesn’t guarantee a sturdy binding or paper that works with your pen.
• Confusing page count with actual capacity: 160 pages usually means 80 sheets. A useful detail for estimating the space you’ll have, as well as the notebook’s weight.
• Overlooking the size: an A5 notebook gives you more room, but also takes up more space in your bag. An A6 notebook is easy to carry, but you get a smaller writing surface.
• Buying a dated diary too late in the year: some pages are likely to stay blank. With an undated planner, you can start whenever you like.
• Choosing paper without checking its weight: 70 to 80 gsm paper is generally fine for taking notes, while a higher weight gives you more substance for certain creative uses. However, compatibility also depends on the ink and how much you apply.

The criteria to check before you choose

1. The right size for your daily life

The A5 format, measuring roughly 14.8 × 21 cm, suits students, teachers and professionals who need a comfortable surface for meetings, classes or journaling. It’s still compact enough to slip into most bags.

The A6 format, around 10.5 × 14.8 cm, is all about portability. It works well for a notebook, a to-do list or jotting down ideas on the go. For a detailed sketchbook, it’s better to go up to A4 or A3, which are far more comfortable.

French school formats, such as 17 × 22 cm or 24 × 32 cm, are particularly handy for homework, lessons and school stationery. Also make sure the notebook will fit properly in your folder or bag.

2. Paper and ruling type

The ruling should match the way you write:

• Lined notebook: ideal for text, lists and meeting notes.
• Grid notebook: useful for tables, diagrams, calculations and plans.
• Seyès notebook: the standard French ruling for school writing and learning calligraphy.
• Blank pages: best for drawing, sketching and free layouts.

Paper weight is a good indicator, but it’s not everything. 100 gsm paper feels more substantial than 70 gsm, while 140 gsm paper is better suited to certain dry techniques and light watercolour. For artistic use, check the manufacturer’s recommendations and test it with your materials.

3. Binding and cover

A spiral binding usually lets you open the notebook flat and turn pages quickly. It’s well suited to students and heavy note-taking, even if the spiral can be a bit bulkier in a pouch.

A sewn or integral binding opens nicely and holds up well, especially on a hardcover notebook or a diary. A hard cover protects the pages better in a bag, while a soft cover is generally lighter.

Finally, check what accessories are actually included: elastic closure, bookmark, pen loop, inner pocket or flaps. These details can make daily use more convenient, but they don’t replace checking the size and paper type.

Frequently asked questions about notebooks and diaries

What size should I choose for a daily planner?

A5 offers a good balance between writing space and portability. If you have lots of appointments or need to write detailed notes, a larger size will be more comfortable. A6 is better suited to quick reminders and being on the move.

Is an undated planner useful for school?

Yes, if you want to organise goals, revision or projects independently of the school holiday calendar. For keeping up with lessons day by day, a dated school diary is usually clearer and more practical.

What’s the difference between a notebook and a diary?

A notebook is mainly for recording practical information, ideas or tasks. A diary is more about personal, regular writing. The choice depends largely on the ruling, size, how private you want it to be and the type of cover.
