Learn how notebook paper weight (gsm) affects ghosting, bleed-through, and writing feel. Use our decision rules to pick the perfect thickness for your pen or art style.
Quick answer
For most fountain pens, markers, and heavy ink work, choose a notebook with 160gsm paper to prevent ghosting and bleed-through. If you use only pencil or ballpoint, 100–120gsm is lighter and still works well.
Paper weight vs. durability
Heavier paper (higher gsm) is thicker and more opaque, which reduces show-through. But it also adds bulk and weight to the notebook. A 160gsm journal will be noticeably heavier than a 100gsm one of the same size and page count.
Writing feel and flexibility
Thicker paper feels stiffer and less flexible. If you like a soft, bendable page that you can fold back easily, a lighter gsm (around 80–100) may feel better. 160gsm pages are sturdy but can feel rigid in smaller formats.
Decision rules for choosing notebook paper weight
- You use fountain pens, markers, or paint pens: Choose 160gsm or higher. Thicker paper prevents ink from soaking through and keeps both sides usable. 160gsm is the sweet spot for most mixed-media and bullet journaling.
- You write mostly with pencil, ballpoint, or fine-liner: 100–120gsm is sufficient. Lighter paper reduces notebook bulk and cost while still handling these tools well.
- You want a slim, portable notebook: Go with 80–100gsm. Fewer pages at low gsm keep the notebook thin and light. Accept that ghosting may occur with wet inks. Trade-off: portability vs. ink resistance.
