I have bought more notebooks than I care to count. Physical ones, digital ones, hyperlinked PDF notebooks, Moleskines stacked in a drawer. I have gifted them, recommended them, and filled them. Over the years I have tried every format: lined pages, blank pages, dot grid, and grid. And I landed firmly on one. But getting there taught me something that most notebook guides get wrong: your notebook format should be chosen based on what you actually do with it, not on what kind of person you think you are.
This is not a guide about personality types or aesthetic preferences. It is a practical breakdown of four notebook formats, what each one is actually good for, and how to figure out which one fits the work you are doing right now. Whether you are shopping for a physical notebook or a PDF notebook you will use on your tablet or e-ink device, the same logic applies.
The Four Formats, Explained Simply
Before getting into recommendations, it helps to understand what each format gives you and what it takes away.
Lined (Ruled) Notebooks
Lined notebooks are the default. They are what most of us grew up with in school, and they are still what you will find in every stationery aisle and notebook template store on the planet. The horizontal lines help you write in straight rows and keep your handwriting consistent.
The constraint is the point. Lines keep your text aligned and readable, and they give you a natural rhythm when writing long-form content. The downside is that lines are rigid. They dictate a specific line height, and they actively get in the way the moment you want to do anything other than write words left to right. On a tablet or e-ink reader, this is even more noticeable because you cannot easily flip to a blank page mid-session.
Blank (Unruled) Notebooks
A blank page is total freedom, which is either thrilling or paralyzing depending on what you are trying to do with it. There are no guides, no constraints, no structure. You can write diagonally, sketch across the full page, draw large diagrams, map out ideas spatially, or mix text and illustration in whatever arrangement makes sense in the moment.
The challenge with blank notebooks is that if you want to write in straight lines, you either train yourself to write naturally level or you find yourself drifting across the page. For pure writing tasks, most people find blank pages harder to use than they expected, whether on paper or on a screen.
Dot Grid Notebooks
Dot grid is lined and blank at the same time. A regular grid of subtle dots covers the page, giving you enough visual guidance to write in rows and draw straight lines, while remaining visually quiet when you are not actively using the structure. The dots are far less dominant than printed lines or a full grid, which makes the page feel open even when you are using it as a guide.
This is the format I use exclusively now, and it is the one I recommend most often. The dot grid gives you the flexibility of a blank page with just enough scaffolding to keep things tidy. You can write, sketch, create tables, draw diagrams, map out a layout, or do all of those things on the same page. The page does not fight you.
On a tablet or e-ink device, dot grid pages look especially clean. The dots recede into the background and let your handwriting or stylus strokes take centre stage, which is part of why dot grid has become the most popular format in PDF notebook templates.
Grid (Graph) Notebooks
Grid notebooks cover the page in a regular pattern of small squares. This gives you the most precise spatial reference of any format, making it easy to draw to scale, create accurate diagrams, align elements precisely, and work with anything technical.
Grid is less popular in general stationery circles but has a devoted following among engineers, architects, mathematicians, and anyone who works with spatial information regularly. The squares can feel visually busy if you are just trying to write prose, but for technical work they are genuinely useful in a way no other format matches. In a PDF notebook, grid pages also work well for budgeting layouts, habit trackers, and anything where column alignment matters.
Stop Choosing Based on Personality. Choose Based on Work.
Most notebook guides will tell you that creatives prefer blank, organised people prefer lined, and technical minds prefer grid. This framing sounds intuitive but it is not especially useful, because the same person can be creative, organised, and technical depending on the day or the project.
A better question to ask is: what am I actually going to write or draw in this notebook?
The format should follow the function. I learned this through my own experience, not through a personality quiz.
When I was writing more: journaling, drafting posts, taking long-form notes, I used lined notebooks. They were the right tool for that work. The structure kept my writing readable and the constraint was not a problem because I was doing one thing: writing words.
As my use of notebooks expanded to include sketching, mapping out product ideas, mixing diagrams with notes, and working on things where spatial thinking mattered, the lined format started getting in the way. I moved to dot grid and never looked back. The dot grid suits the work I do now. It is as simple as that.
A Case Study: The Engineer Who Swears by Grid
I have a close friend who is a web developer. When I try to get him to use a dot grid notebook (which I have done, because I have gifted him several) he always ends up going back to grid.
At first I thought he was just stubborn. Then I watched him work. He was not taking notes or journaling. He was drawing system architecture diagrams, sketching component layouts, mapping data flows, and doing the kind of spatial, technical, precision-oriented thinking that his job demands. The grid squares gave him a consistent unit of measurement he could use across the page. He could make boxes the same size, draw proportional diagrams, and align elements accurately without any additional tools.
For him, grid is not a preference. It is the correct tool for his actual work. Dot grid or blank pages would make his work harder, not easier. If he switched to a PDF notebook on his tablet, he would want grid pages for exactly the same reason.
The Case for Mixed Format Notebooks
One thing I have come to appreciate over time is that most people do not do just one type of work in a single notebook. You might start a session writing a to-do list, move into sketching a layout, and end up drafting a few paragraphs of notes. No single format handles all of that equally well.
This is one of the advantages that PDF notebooks have over physical ones. A well-designed PDF notebook can include multiple page types in a single file: a few lined pages for prose, dot grid pages for mixed content, a grid section for diagrams or tracking. You can jump between them using internal hyperlinks without losing your place or carrying multiple books.
If you are new to PDF notebooks, this flexibility is worth paying attention to. You are not locked into a single format choice the way you are with a physical notebook. You can have the right page type for each type of work, all in one file.
