A5 vs B6 Notebook Size: Which One Should You Buy?
Standing in front of a notebook shelf — or scrolling through one online — most people default to whatever size looks familiar. But an A5 vs B6 notebook decision actually changes how you use it: how many pages fit in your bag, how your handwriting sits on the page, even how often you'll actually open it. If you've ever bought a notebook that ended up too bulky for your bag or too cramped for your handwriting, this guide walks through the real dimensions, the practical trade-offs, and which size fits which routine — plus where ruled or dotted pages make the difference. No jargon, just what actually matters before you buy.
Why Notebook Size Trips People Up
Part of the confusion is that stationery uses two competing size standards. The ISO A-series (A4, A5, A6) is what most Indian offices and schools grew up on, while the B-series (B5, B6, B7) sits in between and is common in Japanese-style and pocket notebooks. Neither is "correct" — they're just different systems, which is why a "medium" notebook from one brand can be a completely different size from another's (source: Adobe's guide to standard paper formats).
That's the real reason size labels feel inconsistent — not that anyone's doing it wrong. Add to that the fact that many Indian stationery stores label notebooks as "pocket diary," "medium," or "large" without giving actual measurements, and it's no surprise most people end up choosing by feel rather than fact. A tape measure — or a quick look at the mm dimensions before you order online — settles it in seconds.
A Simple 3-Step Way to Pick Your Size
If you'd rather skip the theory, here's the short version:
- Measure the space it needs to live in. If it's going in a bag pocket, sling bag, or glove compartment, measure that space first — it rules out one size immediately.
- Estimate how much you'll write per sitting. Long entries and detailed notes need the width A5 gives you; short lists and quick jottings don't.
- Decide how often it travels with you. A notebook that stays on a desk can afford to be bigger; one that's in your bag every day should earn its space.
A5 vs B6: The Real Dimensions
Here's how the two sizes actually compare, measured, not guessed:
| Size | Dimensions (mm) | Dimensions (inches) | Feel in hand | Best for |
|---|---|---|---|---|
| A5 | 148 × 210 mm | 5.8" × 8.3" | Half an A4 sheet — roomy, still portable | Journaling, detailed notes, daily planning |
| B6 | 125 × 176 mm | 4.9" × 6.9" | Noticeably smaller — fits most bags and pockets | To-do lists, quick notes, on-the-go journaling |
Where does B5 fit in? It's the ISO in-between size (176 × 250 mm) — larger than A5, closer to a magazine page, and common in Japanese-style notebooks. We don't currently stock B5 at Lamhenow, but it's worth knowing it exists if you're comparing sizes across brands.
A5 or B6 — Which Suits Your Routine?
A quick way to decide, based on what you'll actually use the notebook for:
- Daily to-do lists you'll carry everywhere → B6. It disappears into a sling bag or jacket pocket.
- Long-form journaling or detailed project notes → A5. The extra width gives your handwriting room to breathe.
- College or office notes you'll flip through often → A5, simply because you'll fit more per page and flip fewer times.
- Gifting someone who prefers something slim and pocketable → B6.
- Already own a bag with a fixed notebook sleeve → measure that pocket before anything else; it overrides every other consideration.
A5 vs B6 for Common Use Cases
Students: A5 tends to win for subject notebooks and revision notes — more words per page means fewer notebooks to carry and flip between during exam season. A B6 pocket notepad works well as a companion for quick to-do lists or timetable reminders.
Working professionals: If most of your writing happens in meetings or at a desk, A5 gives you room for diagrams, action items, and follow-ups on one page. If you're mostly capturing quick notes between calls or commuting, B6 is easier to keep within reach.
Journaling and reflection: Most journaling formats — morning pages, gratitude lists, reflective writing — benefit from A5's extra space, especially if you write in a loose, unstructured way rather than short bullet points.
Gifting, including corporate or bulk gifting: B6 notebooks read as thoughtful, pocketable gifts that don't feel like "just another notebook," while A5 feels more substantial for a planner-style gift. If you're choosing for a group — a team, a client list, a wedding favour — it's worth ordering one of each size first to see which fits the occasion before you commit to a bulk order.
Ruled or Dotted — the Other Decision
Size solves portability; page layout solves how you actually write. Ruled pages suit linear note-taking, to-do lists, and anyone who wants guided lines without thinking about it. Dotted or grid layouts suit bullet journaling, sketching, and custom trackers where you want structure without a hard line dictating everything.
If you're undecided, ruled is the safer everyday default — it's what most people reach for out of habit, and it's currently what Lamhenow's A5 wiro notepads offer, in both ruled and unruled (blank) variants. Either way, the act of writing by hand rather than typing has its own research behind it — one comparative study of university students found handwritten notes were linked to better recall than typed ones (Comunicar, peer-reviewed study), which is as good a reason as any to keep a physical notebook around regardless of size.
A Quick Checklist Before You Buy a Notebook in India
A few things worth checking beyond the size label:
- GSM (paper weight): 70–80 GSM is the standard range for smooth writing without pen bleed-through on the next page. Go heavier if you use gel pens or fountain pens often.
- Binding: Wiro/spiral binding lies flatter for active note-taking; perfect-bound (glued spine) notebooks feel more like a proper book and hold up better for daily carry.
- Recycled content, verified: "Recycled" on a label can mean very little on its own. Look for a specific certification like GRS (Global Recycled Standard), which independently verifies recycled content through the supply chain rather than taking a brand's word for it.
- Price per page, not just sticker price: A ₹70 notebook with 160 pages can work out cheaper per page than a ₹50 one with 60 pages.
- Delivery cost: For something as small as a notebook, shipping charges can quietly double the price — worth checking before checkout.

Frequently Asked Questions
What is the actual size of an A5 notebook?
A5 measures 148 × 210 mm (5.8" × 8.3"), exactly half of an A4 sheet. It's roomy enough for detailed notes or journaling while still fitting most bags — the most common notebook size sold in India.
What is the actual size of a B6 notebook?
B6 measures 125 × 176 mm (4.9" × 6.9"), noticeably smaller than A5. It's the size that fits most jacket pockets, small bags, and glove compartments, which makes it popular for quick notes and to-do lists.
Is B6 too small for everyday note-taking?
Not for short entries, to-do lists, or quick journaling — but if you write long-form or take detailed class notes, A5's extra width gives your handwriting more room to breathe on the page.
Should I choose ruled or dotted pages?
Ruled pages suit linear note-taking and lists; dotted or grid layouts suit bullet journaling, sketching, and custom layouts. If you're unsure, ruled is the safer everyday default.
Does Lamhenow ship notebooks across India with free shipping?
Yes — Lamhenow offers free shipping on all orders with no minimum order value, on both A5 and B6 notebooks.
