Undated Planners: Top Picks for Tailored Organisation

Bought a planner in March, only to find two months of pages are already useless? Does that sound familiar? The undated planner is the perfect solution for anyone who wants total flexibility. Whether you start your year in September, launch a project mid-month, or simply need to take breaks from planning, this tool adapts to your rhythm—not the other way around.

I'm the head of product selection at Joybuy, and my mission is to unearth the gems that make your life simpler. In this guide, I'll give you all the keys to choosing the right undated planner and introduce our top picks to help you get organised without constraints in 2026.

How to Choose the Right Undated Planner for You?

Before you dive in, take a moment to define your needs. What will be the main purpose of your planner? There are three key criteria to consider to make the right choice.

1. Format: Is Portability Key?

The size of your planner directly impacts its daily use.

• Pocket-Sized (A6-style): An A6 notebook slips easily into a bag or a large pocket. It's the ideal companion for jotting down ideas on the fly, managing to-do lists, or keeping a logbook.
• Standard Size (A5-style): The A5 planner strikes the perfect balance between writing space and portability. It's large enough for detailed goal tracking or to serve as a weekly organiser at the office, yet it remains easy to carry.
• Large Formats: Reserved for desktop use, these planners sit proudly on your desk. They offer maximum space for complex project planning, sketching, or mind mapping.

2. Internal Structure: What's Your Organisational Style?

The page layout is a crucial factor. A simple lined notebook will offer you complete freedom. Conversely, an undated weekly planner provides a ready-made template (days of the week, note sections) that you just need to date. Some models even combine monthly and weekly views, perfect for keeping the big picture in focus without losing sight of daily details.

3. Paper Quality and Finishing Touches

The paper weight (expressed in gsm or g) directly affects your writing experience. A 70 gsm paper is a standard that works well with a ballpoint pen. However, if you're a fan of fountain pens or markers, opt for a thicker paper (like 100g) to prevent ink from bleeding through the page. Finally, don't overlook the finishing touches: the type of cover (hard, soft, PU leather) and the little extras (elastic closure, bookmark, pen loop) that make all the difference in terms of durability and convenience.

Recommended Undated Planners

To help you decide, we've selected three models that stand out for their design and cater to very different needs.

Jubiluu A6 Premium Pocket Notebook

Why It Stands Out

This notebook gets straight to the point: maximum portability and impeccable quality for note-taking. Its compact size and rigid PU leather cover make it a reliable and durable travel companion.

Advantages

• A6 Format: Ultra-compact, it fits absolutely anywhere.
• Quality Paper: Its 80 sheets (160 pages) of 100g offset paper provide a smooth and very pleasant writing surface.
• Thoughtful Accessories: It includes a ribbon bookmark, an elastic closure, and a pen loop. Details that make a world of difference in daily use.
• Durable Cover: The rigid PU leather cover effectively protects the pages from the wear and tear of travel.

Who Is It For?

For professionals on the go, creatives who love to capture ideas in the moment, or anyone looking for a discreet and elegant personal journal.

Jubiluu A5 18-Month Undated Planner

Why It Stands Out

Designed for long-term planning, this A5 model offers a complete 18-month structure without ever imposing dates. It's the perfect tool for project tracking or personal organisation that's built to last.

Advantages

• 18-Month View: With 112 sheets (224 pages), it's designed to accompany you over the long term.
• Functional Structure: It combines customisable title pages, monthly views, and weekly two-page spreads with dedicated sections for notes.
• Thick Paper: The off-white 100g offset paper ensures an excellent writing experience, even with markers.
• Balanced A5 Format: Large enough for detailed planning, yet compact enough to be carried in a bag.

Who Is It For?

Ideal for students, project managers, and anyone looking for a structured weekly organiser for medium or long-term goal tracking.

Moleskine Undated Weekly Planner - Large

Why It Stands Out

This Moleskine planner combines the brand's iconic design with total flexibility. It comes with stickers to customise its 12 monthly dividers, leaving you in complete control of your calendar.

Advantages

• Advanced Customisation: The 12 monthly dividers can be dated and organised however you like using the included sticker sheets.
• Smart Weekly Layout: The week is displayed on the left-hand page, while the lined right-hand page is dedicated to your notes, lists, and thoughts.
• The Unmistakable Moleskine Design: It features the signature details that made the brand a success: rounded corners, an elastic closure, a ribbon bookmark, and an expandable inner pocket.
• Certified Paper: The ivory-coloured 70 gsm paper is acid-free and FSC-certified, guaranteeing it comes from responsibly managed sources.

Who Is It For?

For creatives, bullet journal enthusiasts who like to start with an existing structure, and of course, die-hard Moleskine fans looking for a tool that adapts to a non-linear schedule.

Frequently Asked Questions (FAQ)

Why choose an undated planner?

Its main advantage is the freedom it provides. You can start it at any time of the year without ever wasting pages. It's also the perfect tool for projects with shifting timelines or if you simply don't need to plan every single week.

What paper weight should I choose for a planner?

It all depends on your favourite writing tools. A paper weight of 70-80 gsm is sufficient for ballpoint pens and pencils. However, if you swear by fountain pens, markers, or highlighters, a weight of 100g (or more) is essential to prevent ink from bleeding or showing through on the other side.

How do I get started with an undated weekly planner?

The key is to keep it simple. Take the time to fill in the current week, then use the monthly views to note important upcoming dates (birthdays, appointments, etc.). Don't hesitate to adopt a colour-coding system to distinguish between your professional and personal activities. The most important thing is to build a system that reflects you and works for you.
