THE SHORT ANSWER
Start with where the notebook will be used: A4 gives more writing space, while smaller formats are easier to carry. Then choose ruling for the task, enough pages for the subject and paper that works with your preferred pen. GSM indicates paper weight per square metre, but finish and opacity also affect writing performance.

Need
Useful starting point
Why
Class notes
A4 or a familiar school format, ruled
Room for headings, diagrams and longer notes

Choose the size around the task
A4 notebooks offer a broad page for classroom notes, calculations and diagrams. A5 and other compact formats are easier to carry and suit short notes, lists and journalling. Product dimensions are more dependable than informal size names, so check the measurements when fit matters.
Match the ruling to the work
•
Single line: general writing and notes
•
Four line: early English handwriting practice
•
Double line: handwriting practice, including scripts taught with two guides
•
Square/grid: mathematics, tables, graphs and aligned working
•
Plain/unruled: drawing, diagrams and flexible layouts
What paper GSM tells you
GSM means grams per square metre and describes the paper’s basis weight. A higher GSM generally means a heavier sheet, but it does not guarantee smoothness or complete resistance to ink showing through. Paper coating, opacity and the pen itself also matter.
•
Everyday notebooks often use lighter paper to keep weight and cost manageable
•
Heavier paper can be useful with wetter ink or when writing on both sides
•
For rollerball, marker or fountain-pen use, test compatibility rather than relying on GSM alone
Page count, binding and covers
More pages suit a long course but make a notebook heavier. Spiral binding can lie flatter and fold back, while centre-stitched or case-bound formats may pack more neatly. A firmer cover helps when the notebook is carried daily or used without a desk.
Check the product details before buying
Confirm whether the displayed count refers to pages or sheets, the exact ruling, physical dimensions and whether options change the size or page count. ShopStory lists available options on each product page so you can select the required version before adding it to your bag.
Frequently asked questions
Does higher GSM always mean better paper?
No. Higher GSM means heavier paper, but smoothness, opacity, coating and suitability for a particular pen can still vary.
Is A4 or A5 better for students?
A4 provides more room for class notes and diagrams. A5 is more portable. The best choice depends on the subject, school requirements and how the notebook will be carried.
What ruling is useful for mathematics?
Square or grid ruling helps keep numbers, graphs and calculations aligned. Some students may still prefer single-line paper when required by their school.
