Diary and notebook: how to choose the right format for your everyday life

A diary or notebook can quickly become a burden, run out of space or end up at the back of a drawer if it doesn’t suit your habits. A student won’t have the same needs as a professional who’s often on the move, a creative person or someone who wants to keep a personal journal.

Before you buy, it’s worth looking beyond the cover and considering a few practical points: the format, page layout, paper quality and accessories you’ll actually use.

Common pitfalls to avoid before you buy

1. Mistaking attractive design for a durable cover

An elegant cover doesn’t necessarily mean it’ll stand up to life in your bag. With regular use, corners can get damaged, pages can crease and the binding can become uncomfortable.

A hardback cover or PU imitation leather finish can provide extra protection. Do check the care instructions, though. Most of the models featured here should be kept away from moisture and cleaned with a soft cloth, without harsh products.

2. Choosing a format that doesn’t suit how you’ll use it

An A6 notebook slips easily into a bag or pocket, but has limited writing space. An undated A5 planner, on the other hand, gives you more room to organise projects, track goals or take detailed notes, though it takes up more space on your desk.

A 21 × 27 cm diary can be very practical for school or work thanks to its generous writing area, but is less convenient in a small bag. The right format depends on your journeys, how much weight you’re happy to carry and how much information you need to write down.

3. Overlooking the type of planning you need

A weekly diary lets you see upcoming appointments and tasks at a glance. A daily diary offers more detail, but takes up more space and may leave many blank pages if your days aren’t very busy.

An undated planner is particularly useful if you’re starting a project at any time of year. It avoids wasting pages when several days or weeks go by without being used — a real advantage for study, personal goals or creative journalling.

What to check before choosing

Format and capacity

  • A6, approximately 10.5 × 14.8 cm: ideal for quick notes, lists, ideas and journalling on the go.
  • A5, approximately 14.8 × 21 cm: more comfortable for schedules, projects and detailed note-taking.
  • Large format, such as 21 × 27 cm: a good choice for a school or work diary that stays mainly on a desk.

Also check the number of sheets. An 80-sheet notebook has 160 pages, while an undated A5 planner with 112 sheets can offer 224 pages and help you stay organised for much longer.

Paper and pen compatibility

The paper weight gives you an initial indication, but it isn’t enough to predict how every type of ink will behave. At 100 g/m², offset paper is generally thicker and more pleasant to write on than 70 g/m² paper, especially for daily notes and corrections.

If you use an erasable gel pen, check the nib size and erasing mechanism. Fine 0.5 mm nibs are ideal for writing in small boxes and adding precise notes. Their thermosensitive ink can be erased by friction, but should be used in accordance with the manufacturer’s recommendations and shouldn’t be considered permanent.

Accessories that are genuinely useful

A notebook with an elastic closure and bookmark stays shut in your bag and helps you quickly find the last page you used. A notebook with a pen loop also saves you from having to search for your pen at the bottom of your bag. These little details are particularly useful for students, travellers and anyone who takes notes while out and about.

Frequently asked questions

Which format should I choose for an everyday notebook?

A6 is ideal for quick notes and taking with you on the go. For longer writing sessions, project planning or keeping a detailed journal, A5 gives you more comfortable writing space.

Is an undated planner worth it?

Yes, if your routine varies or you’re starting to get organised part-way through the year. Unused pages aren’t tied to fixed dates. A dated diary is still more convenient if you want to see appointments and deadlines at a glance.

How long can a diary stay in good condition?

Its lifespan depends on how often you handle it, how you carry it and how much moisture it’s exposed to. A hardback cover, elastic closure and storage in a dry place can help slow down wear and tear. To protect the paper and cover, keep it away from water, direct heat and harsh cleaning products.
