How to Choose a Notebook for Your Planner System: Paper, Size, and Binding

Quick Answer

The best notebook for your planner system balances paper quality, size, and binding to match how you actually plan. Start with a dotted grid in A5 size with lay-flat binding for maximum flexibility—it works for writing, sketching, and custom layouts. If you use heavy markers or paint, prioritize thick paper (160gsm or higher) to prevent ghosting and bleeding.

Choosing a notebook for your planner system is more than picking a pretty cover. The right paper, size, and binding affect how your planner feels, how it holds up to daily use, and whether you actually enjoy using it. Whether you're a bullet journaler, a creative planner, or a mindfulness journaler, the wrong choice can make planning feel like a chore.

This guide breaks down the key decisions—paper type, size, and binding—so you can match a notebook to your planning style. We'll also look at specific products from Shop ARL that meet different needs.

Paper Types: Dotted, Lined, Blank, and Grid

The paper type is the first big decision. Dotted paper gives you structure without the visual weight of lines, making it ideal for layouts, habit trackers, and creative spreads. Lined paper is best for heavy text journaling, while blank paper suits sketching and mind mapping. Grid paper offers precise structure for detailed planning.

Paper weight matters as much as the pattern. Thin paper (less than 100gsm) may ghost or bleed when you use markers, gel pens, or paints. Thicker paper (150gsm or higher) handles wet media better. For example, the Cherry Notebook from Shop ARL offers ultra-thick paper that withstands most markers, pens, and even paints without ghosting or bleeding—a great option if you like to add color.

• If you use markers or paints, choose at least 150gsm paper to avoid bleed-through.
• Dotted paper is the most versatile for planner layouts—it guides but doesn't constrain.
• Blank paper is best if you prefer freeform journaling or sketching.

Size: A5 vs. Other Formats

Size affects portability and how much content fits on a page. A5 is the most popular for planner systems because it balances space and portability—it fits in most bags and still gives you room for weekly spreads and notes. Smaller sizes like A6 are more portable but limit layout options. Larger sizes like B5 offer more space but are heavier and less convenient to carry.

Think about where you'll use your planner. If you plan at a desk, a larger size might work. If you carry it everywhere, A5 or smaller is more practical. The Cherry Notebook is A5, a versatile size that works for both desk and on-the-go planning.

• A5 is the sweet spot for most planner users—portable yet spacious.
• If you travel light, consider a pocket-size notebook for quick notes.
• For detailed layouts, a larger notebook gives you more room but adds bulk.

Binding: Lay-Flat vs. Traditional

Binding affects how the notebook opens and lies flat. Lay-flat bindings (such as spiral or certain stitched bindings) allow you to write comfortably across the full page without pressing down. Traditional glued bindings may not open fully, making it harder to write near the spine. For planner use, lay-flat is usually the best choice.

If you plan to use your notebook on a desk or in your lap, lay-flat binding is a must. Spiral bindings are flexible but can snag in bags. Stitched bindings are durable and open flat but may not be as flexible. Consider how you'll use the notebook—if you'll write on both sides of the page, lay-flat is essential.

• Lay-flat binding is best for writing near the spine without gaps.
• Spiral bindings are flexible but can catch on fabric.
• Stitched bindings are durable and open flat, ideal for long-term use.

Decision Rules for Choosing Your Notebook

• If you use markers or paints: Choose a notebook with paper weight of at least 150gsm to prevent ghosting and bleeding. The Cherry Notebook offers 160gsm dot grid and 150gsm blank ivory options. Check the paper weight before buying—thicker is better for wet media.
• If you want a structured planner: A dated planner like the 2026 Doodle Planner provides monthly and weekly spreads, mood trackers, and goal pages, so you don't have to set up layouts yourself. Consider a dated planner if you prefer ready-made structure over a blank notebook.
• If you want flexibility: A dotted notebook like the Cherry Notebook gives you structure without lines, making it easy to create custom layouts, habit trackers, and creative spreads. Dotted paper is the most versatile choice for planner systems.
