Most people pick a notebook cover colour and almost accidentally choose a ruling. Then they spend the year fighting a blank page that doesn't match how their mind works. The ruling is not a minor preference — it is the primary interface between your ideas and the paper.

Leuchtturm1917 notebooks are available in three ruling styles — Dotted, Ruled (Lined), and Plain (Blank) — each designed for a different relationship with the page. Add in the Squared (Grid) option available on select formats, and the decision becomes genuinely worth thinking about before you commit.

This guide breaks down each ruling type, which use cases it suits, and how to pair it with the right cover format. By the end, you will know exactly which Leuchtturm1917 belongs in your bag.

📌 The Three Main Rulings

📐 Dotted Grid — The Flexible Standard

The 5mm dotted grid is Leuchtturm1917's most popular ruling by a wide margin, and for good reason. The dots are light enough to disappear when scanned or photographed, yet present enough to keep your writing straight and your diagrams aligned.

Dotted is the ruling that works equally well for:

• Bullet journalling — spreads, habit trackers, weekly layouts, future logs
• Technical sketching and architecture planning
• Mixed-use notebooks (some pages for lists, others for maps or charts)
• Calligraphy practice where you want guides but not hard lines
• Design students and UX professionals who sketch wireframes

If you are new to Leuchtturm1917 and uncertain which ruling to choose, start with Dotted. It is the most forgiving and the most versatile. Virtually every Leuchtturm1917 colour and size is available in Dotted, making it the default choice for both personal and corporate gift orders.

✍️ Ruled (Lined) — The Classic Note-Taker

Leuchtturm1917's 6mm ruled lines are drawn on the chamois paper with a subtle grey ink that is visible but not distracting. The ruling is wider than many school exercise books, which gives writing more room to breathe — especially important for fountain pen users whose letterforms tend to be slightly larger.

Ruled is the right choice when:

• You write more than you sketch — university lectures, professional notes, diaries
• Your handwriting is larger or tends to drift without horizontal guides
• You are keeping a prose journal or writing long-form thoughts
• You want your notes to look neat and uniform

Lined notebooks remain popular in Singapore's professional and academic communities, where note density matters and the structure of lines supports fast, legible handwriting during meetings and seminars.

🎨 Plain (Blank) — The Artist's Canvas

Blank pages are the ultimate commitment to freedom. There are no guides at all — just the chamois field waiting for whatever you bring to it.

Plain works best for:

• Sketching, illustration, and watercolour wash (using the correct paper weight)
• Mind mapping and spider diagrams where structure is radial, not linear
• Travellers using notebooks as visual journals or collage books
• Writers who find lines subconsciously constraining their prose
• Children's creative notebooks where every page is a canvas

The Plain ruling is also increasingly popular for fountain pen users who want to practice a mix of calligraphy scripts — italic, copperplate, Spencerian — without conflicting horizontal guides.

📓 Hardcover vs Softcover — The Other Decision

Once you have chosen your ruling, the second decision is cover type. Leuchtturm1917 offers both Hardcover and Softcover (Paperback) versions of their most popular sizes.

💡 Hardcover — Durability and Protection

The hardcover is the original and most recognised form factor. The stiff cover boards protect the pages from bending, making it ideal for desk use and for notebooks that will live in a bag for months. The elastic closure wraps around the outside to keep everything secure.

Choose hardcover when:

• The notebook will be heavily used and needs to last a full year or more
• You write while resting the notebook on your lap or another surface
• You want the notebook to maintain its spine and structure when shelved
• It is a corporate gift or a long-term reference journal

🖊️ Softcover — Flexibility and Weight

The softcover (Paperback) version is lighter, slightly thinner, and the cover flexes flat — useful when you want the notebook to fold back on itself completely. It is the preferred format for travellers and anyone who carries their notebook in a jacket pocket.

Choose softcover when:

• Weight in a travel bag is a concern
• You need the notebook to flatten on tight desk surfaces
• The pocket format (A6) will be carried in a trouser or jacket pocket
• You prefer a more minimal, less structured aesthetic

📌 Ruling by Format — Quick Reference

Ruling	Best for	Available Sizes
Dotted	Bullet journalling, mixed-use, designers, sketching	A6, B6+, A5, A4+, Master Slim
Ruled	Academic notes, diaries, long-form writing, meetings	A6, B6+, A5, A4+, Master Slim
Plain	Sketching, mind maps, calligraphy, creative journals	A6, B6+, A5, A4+
Squared	Mathematics, engineering, cross-stitch planning	A5, A6 (select colours)

✍️ Size and Ruling Together — How to Decide

The size you carry affects how your chosen ruling feels. A Pocket A6 in Dotted becomes a rapid-capture everyday carry notebook — small enough for a shirt pocket, versatile enough for lists, sketches, and impromptu notes. The same dotted ruling in an A5 Medium becomes a spread-friendly bullet journal with room for weekly overviews and detailed trackers.

Conversely, Ruled works better in larger formats — the lines in an A6 Pocket can feel crowded for larger handwriting, whereas an A5 Ruled notebook gives each line enough room to breathe.
