An undated A5 planner lets you start organising whenever you like, without losing pages if your routine changes. This format is just as suitable for students and professionals as it is for creatives and anyone who wants to bring planning, goals and notes together in one place.
However, carefully presented photos and promises of versatility are not enough to guarantee the right choice. Here are the criteria to consider before buying, along with a selection of models suited to different needs.
An undated planner can be practical, but not all models offer the same structure. Some are limited to lined pages, while others include monthly and weekly layouts, as well as dedicated spaces for goals.
If you are looking for something to manage your everyday life, check for clearly labelled sections. A simple notebook will work perfectly well for jotting down ideas, but it will be less suitable for keeping track of appointments and deadlines.
The A5 format, measuring approximately 14.8 × 21 cm, offers more space than a pocket notebook. However, it can become bulky in an already full bag. By contrast, an A6 notebook generally measures around 10.5 × 14.8 cm and is easier to carry, at the expense of a smaller writing area.
Before ordering, think about how you will actually use it: at your desk, in a lecture theatre, on public transport, in meetings or while travelling frequently.
A hardcover planner will generally withstand repeated handling better than a softcover model, but it may also be bulkier. The covering also requires suitable care. Polyurethane, for example, can be cleaned with a slightly damp soft cloth, without harsh products or excess water.
An elastic closure, page marker or pen loop can make a real difference to everyday convenience. However, these are functional accessories, not an absolute guarantee of long-term durability.
For regular use, choose paper that is sufficiently thick and whose specifications are clearly stated. The Jubiluu models featured here use 100 g/m² off-white offset paper with lined pages. This thickness generally feels more pleasant to write on than very thin paper, although the result also depends on the ink and pen you use.
If you write with a fountain pen or felt-tip pen, check whether the manufacturer provides precise information about paper show-through and the risk of ink bleeding through. If no information is available, it is best to be cautious with very fluid inks.
An undated 18-month A5 planner may include a customisable introductory page, monthly double-page spreads and weekly pages with space for notes. This combination allows you to plan a project, track your habits or organise professional tasks without relying on a pre-set calendar.
For a student planner, pay particular attention to the size of the boxes and the space provided for classes, assignments and exams. For a professional planner, notes pages and the readability of the weekly layouts may matter more than decorative features.
A notebook with an elastic closure and page marker stays securely closed in a bag and makes it easy to find the page you are using. A pen loop also reduces the risk of forgetting your pen when you are out and about.
These accessories do not turn a notebook into a refillable undated planner. If you want to move pages, add refills or change the internal layout, look specifically for a ring- or disc-bound system. The bound models presented below are designed to be used as they are.

Yes, provided it includes clearly identifiable weekly or daily pages. A model made up solely of lined pages is more of a notebook than a true planner designed to organise your everyday life.
The A5 format offers a more generous writing area, suitable for schedules, detailed lists and projects. The A6 format is more compact and slips easily into a pocket or small bag. The right choice therefore depends on the balance you want between visibility and portability.
Keep it in a dry place and avoid exposing it to sunlight, heat or moisture for long periods. Clean the cover with a soft cloth and do not force it open. Also handle the elastic, page marker and pen loop gently, without pulling them excessively.
