A6 vs A5 Notebooks: Which Size Is Right for You? Benefits, Differences & How to Choose

Choosing a notebook can feel surprisingly personal. You pick one up, flip through the pages, test how it feels in your hand… and suddenly you’re wondering if this size is actually going to work for the way you write, plan, or jot ideas on the go. Two of the most popular options you’ll see everywhere—especially if you love clean, functional stationery—are A6 and A5.

At LAPIS PAPEL, we hear this question all the time: “Should I go with the smaller A6 or the slightly bigger A5?” The short answer is that both are excellent. The longer (and more helpful) answer is that each shine in different situations. In this guide we’ll walk through the real-world benefits of each size, compare them side by side, and help you figure out which one fits your life best. No fluff, just practical info so you can grab the notebook you’ll actually use every day.

Quick Size Refresher: What Exactly Are A6 and A5?

Before we dive into benefits, let’s get the measurements straight. These sizes come from the international ISO 216 standard (the same system that gives us A4 printer paper).

• A5 measures 148 × 210 mm (about 5.8 × 8.3 inches).
• A6 measures 105 × 148 mm (about 4.1 × 5.8 inches).

In other words, an A6 page is exactly half an A5 page. If you fold an A5 notebook in half, you basically get two A6 sheets. That simple relationship is why so many people end up owning both sizes—they complement each other beautifully. Now let’s look at why you might fall in love with one (or both).

A6 Notebook Size Benefits: Small but Mighty

A6 notebooks are the underdogs that many people underestimate until they try one. Here’s why they earn a permanent spot in bags, pockets, and daily routines.

 

1. Seriously portable and travel-friendly
An A6 notebook slides into almost any bag without adding bulk. Backpack side pocket? Yes. Crossbody? Easy. Even those slim laptop sleeves that barely fit anything else? An A6 often works. When you’re hopping on a plane, train, or just walking around a new city, the last thing you want is a notebook that feels like another item to manage. A6 disappears until you need it.

2. Fits in a pocket (yes, really)
Many jackets, coats, and even some jeans pockets can swallow an A6 notebook. This is a game-changer for people who like to capture thoughts the moment they appear—while waiting in line, sitting on a park bench, or standing on a crowded subway. No digging through a bag required. Just pull it out, write, and put it back.

3. Perfect if you write small
If your handwriting naturally leans neat and compact, an A6 page gives you just the right amount of space. You don’t end up with half-empty lines or feeling like you’re wasting paper. Bullet journalers who keep tight spreads, list-makers, and anyone who prefers short daily notes often find A6 feels “just right.”

4. Lightweight
Less paper and a smaller cover mean less weight. When you’re already carrying a laptop, water bottle, and maybe a book, every gram counts. An A6 notebook barely registers, so you’re more likely to bring it everywhere instead of leaving it at home “just this once.”

5. Ideal for on-the-go planning and notes
Quick grocery lists, meeting action items, random ideas that hit while you’re walking, travel itineraries, gratitude notes at the end of the day—A6 handles all of these without feeling oversized. Many people keep one as their “pocket brain” and a larger notebook at home for deeper work.

6. Easy to hold in one hand
You can write while standing, leaning against a wall, or holding a coffee in the other hand. The compact size sits comfortably in your palm, which makes spontaneous note-taking feel natural instead of awkward.

7. Often more affordable
Because the paper is smaller, A6 notebooks usually cost less than their A5 counterparts (all else being equal—same paper quality, binding, and cover). That makes it easier to own a few: one for work, one for personal ideas, one for travel. At LAPIS PAPEL you’ll notice the price difference is friendly enough that many customers end up grabbing more than one.

A6 is the notebook that says, “I’m always ready.” It’s low-commitment, high-utility, and quietly becomes a daily companion and everyday carry (EDC).

A5 Notebook Size Benefits: The Everyday Sweet Spot

A5 hits a sweet middle ground that a lot of people settle into long-term. It’s still portable, but it gives you more breathing room on the page. Here’s why so many stationery lovers call it their default size.

1. Perfect if you write larger or like more space
If your handwriting is on the bigger side, or you simply prefer not to cram everything into tiny lines, A5 feels generous. You can write full sentences without the page feeling crowded. Journalers who enjoy longer entries especially appreciate this.

2. Large enough for longer notes and entries, yet still portable
You get roughly twice the writing space of an A6 on every page. That means room for detailed meeting notes, multi-step project plans, daily reflections that go beyond a few lines, or even light sketching alongside text. At the same time, it still fits comfortably in most backpacks, tote bags, and work bags. It’s not “huge”—it’s just right for everyday carry.

3. Twice the space of A6
This is the math that sells a lot of people. Same number of pages, but each page offers double the real estate. If you fill notebooks quickly or hate the feeling of running out of room mid-thought, A5 reduces that friction.

4. Easy to carry in various bags
While it won’t vanish into a jacket pocket the way an A6 can, an A5 slides into virtually any bag you already use. Work tote, gym bag, weekend duffel, student backpack—no problem. Many people keep one in their everyday bag and never think twice about the size.

5. Comfortable to hold while writing
Whether you’re sitting at a café table, writing in your lap on the couch, or perched on a park bench, an A5 notebook rests nicely. The slightly larger footprint gives your hand a stable surface without forcing you to hunch or adjust constantly. It’s also easy to prop open with one hand while you write with the other.

6. Easy to find on a desk
When your desk has a laptop, a few pens, maybe a water bottle and some mail, a small A6 can sometimes disappear under papers. An A5 has enough presence that you can spot it quickly. That little bit of visibility encourages more consistent use.

7. Looks professional and intentional on a desk
There’s something satisfying about an A5 notebook sitting next to your keyboard or at a meeting table. It reads as purposeful without being bulky. Many professionals keep an A5 as their main work notebook for exactly this reason—it feels polished while still being practical.

A5 is the notebook that grows with you. It’s versatile enough for both quick notes and deeper writing sessions.

Side-by-Side Comparison: A6 vs A5 at a Glance

Feature	A6	A5
Dimensions	105 × 148 mm	148 × 210 mm
Writing space per page	Compact	Roughly double A6
Portability	Excellent (pocket-friendly)	Very good (bag-friendly)
Best for handwriting	Smaller / neater	Larger or more expansive
Weight	Lightest	Still light, slightly more
Typical use cases	Travel, quick lists, pocket notes	Daily journaling, work notes, planning
Desk presence	Minimal	Noticeable and professional
Cost tendency	Often lower	Slightly higher

Both sizes use the same paper standards, so if you love a particular paper weight or ruling (grid, dot grid, lined), you can usually find it in both A6 and A5.

How to Decide: Matching Size to Your Real Life

Still not sure? Think about how and where you actually write most often.

Choose A6 if… 

• You move around a lot during the day.
• You want something that can live in a pocket or the tiniest bag.
• Your notes tend to be short and frequent.
• You already carry a larger notebook at home or in the office and want a mobile companion.
• You like the idea of keeping several specialized notebooks (one for ideas, one for lists, one for travel).
• Budget and lightness matter.

Choose A5 if… 

• You write longer entries or detailed notes.
• You want one main notebook that does most of the work.
• You often write while sitting (desk, café, couch, train seat).
• You value having more space without jumping all the way to A4.
• You like your notebook to feel present on your desk or meeting table.
• You’re building a daily journaling or planning habit and want room to expand.

Many people in the LAPIS PAPEL community end up with both—an A6 for the bag or pocket and an A5 for deeper work is a popular combination. They share the same paper quality and design language, so switching between them feels seamless.

Real-Life Scenarios

The frequent traveler
A6 wins for most trips. It fits in a personal item under the seat, slips into a jacket for museum days, and doesn’t weigh down a daypack. Some travelers keep a small A6 for daily logistics and an A5 for longer trip reflections once they’re back at the hotel.

The office or hybrid worker
A5 is usually the daily driver. It looks intentional in meetings, has space for action items and follow-ups, and still fits in a work bag. An A6 can live in a jacket pocket for hallway conversations or quick client calls.

The journaler or morning-pages person
If your pages tend to run long, A5 gives you room to breathe. If you prefer shorter, more frequent check-ins, A6 keeps the habit light and low-pressure.

The student or lifelong learner
A5 handles lecture notes and study summaries well. A6 is perfect for flash-card style lists, vocab, or questions to ask later.

The creative who mixes words and sketches
Both works, but A5 offers more canvas. A6 is great for quick idea capture that you later expand in a larger book.

A Few Extra Tips for Getting the Most from Either Size

• Pair the size with the right paper. Dot grid is popular for both because it supports writing, lists, and light sketching without locking you into lines.
• Consider the binding. Lay-flat or sewn bindings make either size more pleasant to use.
• Start with one and live with it for a couple of weeks. You’ll quickly notice whether you wish the pages were bigger or the notebook was smaller.
• Don’t overthink “perfect.” The best notebook is the one you actually open.

Final Thoughts: There’s No Single Winner

A6 and A5 aren’t rivals—they’re tools for different moments. A6 maximizes freedom and presence in the world. A5 maximizes space and comfort when you sit down to think. The “right” choice depends on your handwriting, your bags, your routines, and even your mood that month.

The good news? You don’t have to choose forever. Many stationery enthusiasts rotate or keep both sizes in their rotation. At LAPIS PAPEL we’ve designed our notebooks so the experience feels consistent whether you pick the compact A6 or the roomier A5—same thoughtful paper, clean design, and attention to the small details that make writing feel good.
