How to choose

Purpose (click to expand)
If you take long-form notes or sketch, A4 or B5 gives room. For daily journals and easy carry, A5 or composition is better. Think where it will live — bag, desk, or shelf.
Portability & feel (paper weight matters)
Heavier paper (80–120 gsm) feels nicer and reduces bleed. Softcover = lighter; hardcover = durable and better for long-term notes.
Binding & layout
Lay-flat binding is best for writing across the spread. Ruling (lined, dotted, plain) affects how you use the page — dotted for bullet journals, lined for notes, plain for sketches.

Paper types & ruling

  • Dotted: flexible layout for both writing & drawing.
  • Lined (college/ruled): best for structured notes — our composition notebooks use this.
  • Plain: ideal for sketching and freeform ideas.

Tip: if you use ink pens a lot, choose 100 gsm+ paper to prevent show-through.
