Undated Planners: Top Picks for Custom Organisation

Starting a planner in the middle of March, leaving weeks blank during your holidays, or simply wanting a tool that adapts to your own pace... The constraints of a traditional planner can often lead to frustration and waste. In response, the undated planner emerges as the ideal solution. Its principle is simple: to give you the freedom to start whenever you want, take breaks without losing pages, and structure your time exactly as you see fit.

This guide is here to help you choose your next organisational partner. We'll review the key criteria to consider and present a selection of models suited for every profile: professional, student, or creative.

How to Choose the Right Undated Planner for You

To find the perfect fit, a few criteria should be scrutinised based on your intended use.

Format: A Matter of Portability and Space

The size of your planner directly impacts its daily usability.

• A5 Size (14.8 x 21 cm): The sweet spot between writing comfort and portability. An A5 notebook provides enough room to detail your days or take notes in meetings, while still fitting easily into any bag.
• A6 Size (10.5 x 14.8 cm): More compact, this pocket planner is the perfect companion for those on the go. It's ideal for quickly jotting down appointments or tasks without weighing you down.

Paper Quality: The Secret to a Pleasant Writing Experience

The paper weight, expressed in grams per square meter (g/m?), determines the paper's thickness and durability. A 100 g/m? paper is highly sought after because it prevents ink from ghosting or bleeding through, even with a fountain pen or fine-liners. Thinner paper, around 70 g/m?, will work for ballpoint pens but will show its limitations with other types of pens.

Layout: From Classic Weekly Spreads to Creative Bullet Journaling

This is the key advantage of the undated planner: its flexibility. Some models come pre-structured as a weekly planner, with the days of the week on one side and a space for notes on the other. Others, completely blank or simply lined, are a perfect blank canvas for fans of bullet journaling (or bujo), who can create their own organisational system.

Frequently Asked Questions About Undated Planners

Why choose an undated planner?

An undated planner is, above all, a choice for freedom. You can start it at any time of the year without wasting pages. It's the perfect solution for non-traditional work schedules or projects that don't align with a standard calendar. You can take a break for several weeks and pick up your planning right where you left off, without a single wasted page.

What paper weight should I choose to prevent ink bleed-through?

To be on the safe side, aim for paper between 90 and 100 g/m?. Its thickness will handle most pens (including fountain pens and fine-liners) with little to no ghosting or bleed-through. If you're a fan of ballpoint pens, a 70 or 80 g/m? paper will do the job just fine.

How do I get started with an undated planner?

Start by defining your needs. Do you need a monthly overview, detailed weekly tracking, or task lists? Once your goal is clear, simply date the pages as you need them. Feel free to use stickers, colour codes, or symbols to create a system that reflects you, much like with a bullet journal. The key is to make the tool your own so that it motivates you and simplifies your life.
