Sticker books have become more than just nostalgic keepsakes—they’re creative tools, collector’s albums, and even calming hobbies for people of all ages. But if you’ve ever tried to design or buy one, you’ve probably run into the sizing conundrum: A6, A5, or B5?
It’s not just about choosing what looks cute or what’s on sale. The size you go with impacts how you use it, how much it can hold, and how portable or display-worthy it really is.
Let’s break it all down and figure out which size makes the most sense for your sticker needs.
Understanding the Basics of A6, A5, and B5 Sizes

Before we dive into what each is best for, here’s a quick size reference to keep in mind:
Size | Dimensions (mm) | Dimensions (inches) |
A6 | 105 × 148 | 4.1 × 5.8 |
A5 | 148 × 210 | 5.8 × 8.3 |
B5 | 176 × 250 | 6.9 × 9.8 |
These are standard paper sizes used globally (especially in stationary and printing), and the sticker book industry has adopted them for practical reasons—they’re predictable, easy to produce, and compatible with printing tools and pouches.
A6: The Mini Marvel
Best for: Travel-sized collections, kids, casual sticker fans
A6 might be the smallest of the bunch, but don’t underestimate it. Its compact size makes it incredibly portable. If you’re someone who likes to stick (pun intended) to a minimalist lifestyle or you want to carry your sticker book in your purse or backpack without taking up too much space, A6 is the go-to.
This size is especially popular with younger kids—it fits their smaller hands and feels like their own little journal. It’s also ideal for thematic collections, like keeping all your animal stickers in one place, or using it as a quick-access reference for reusable stickers.
And speaking of reusable sticker book options, the A6 format often pairs beautifully with them. A reusable sticker book in A6 size allows you to rearrange your stickers anytime, and it doesn’t overwhelm younger users with too much space to fill. If you’re buying for a child or need something for light use, this is the sweet spot.
A5: The Versatile All-Rounder

Best for: Everyday sticker journaling, mid-sized collections, functional and decorative use
A5 is arguably the most balanced size. It’s large enough to give your creativity room to breathe but small enough to be portable. Think of A5 as the planner-lover’s dream format. You can easily use it alongside your bullet journal or planner, placing matching stickers by month or theme. It fits in most medium-sized bags and drawers, making it practical for daily or weekly use.
What makes A5 especially attractive is that it’s versatile across age groups. Whether you’re a teen who loves decorating school supplies or an adult who’s just discovered the peaceful joy of sticker organizing, A5 adapts to you.
Why choose A5?
- It’s great for printable sticker kits (which often come in A5 sheets).
- You can section it—add tabs, create themes, or track sticker inventory.
- Most sticker book brands default to A5 as their “standard” because it suits a wide range of uses.
If you want something that’s not too big or too small and can grow with your hobby, A5 is the way to go.
B5: The Bold and Spacious Option
Best for: Serious collectors, artists, visual planners, and large-format sticker layouts
B5 steps things up. With a noticeably bigger canvas, this size caters to people who aren’t just casually using stickers—but curating them. B5 is especially useful if you’re into:
- Oversized sticker sheets
- Intricate sticker collages
- Mixing art with sticker layouts (e.g., using watercolors or washi tapes as background)
- Designing scenes, like scrapbook-style arrangements or mood boards
The added space gives you visual breathing room. You’re not confined to tight margins or small sticker sets. For people who treat sticker collecting as art, or who work in creative fields, B5 feels generous and freeing.
Of course, the tradeoff is portability. B5 sticker books are better suited to your desk, studio, or bookshelf. They don’t travel quite as well, but they reward you with space to dream big.
How to Choose the Right Size for You

The best size depends on your personality, purpose, and priorities. Here are a few guiding questions to help you decide:
- How do you use stickers? If you’re journaling or using them in planners, A5 might be the most functional. For collecting or showcasing larger designs, go B5. For quick fun and portability? A6.
- Do you want to carry it around or leave it at home? A6 fits in most pockets and handbags. A5 can be carried around in larger bags. B5 is better left on the shelf or workspace.
- Do you work with large or small sticker sheets? A6 books often suit die-cut stickers or minis. A5 fits standard sheets. B5 is ideal for custom or oversized sheets.
- Is this for a child or adult? Kids usually prefer smaller, manageable books (A6 or A5), while adults tend to gravitate toward A5 or B5 depending on usage style.
Design Considerations: What to Look for Beyond Size
Once you’ve chosen the right size, it’s important to think about the quality and layout of the sticker book itself. Here are a few things to look for:
- Page material: Silicone-coated pages (found in good reusable sticker books) let you peel and reposition stickers without tearing.
- Binding style: Spiral or lay-flat binding is much easier to work with if you’re frequently adding or removing stickers.
- Cover design: Make sure the cover reflects your personality or collection type. Some people like cute characters, others prefer minimalist styles.
- Refillability: Some larger books allow you to add or rearrange pages.
These elements affect how enjoyable and practical the sticker book is over time—especially if you’re investing in a bigger size like A5 or B5.
Function First, Fun Always
Sticker books should be joyful, not stressful. The size you choose—A6, A5, or B5—should serve the way you already enjoy stickers. There’s no “wrong” option, only what works best for your routine or your imagination.
If you’re still unsure, start with A5—it’s the most forgiving and gives you room to grow. Later, you might want to pick up an A6 for travel or a B5 for your home studio. Many collectors end up owning multiple sizes for different reasons—and honestly, that’s part of the fun.
And if you’re eyeing something that you can use and reuse, go with a reusable sticker book. It’s a clever way to experiment, reorganize, and express yourself without the pressure of getting it “right” the first time.
