So You Need the Exact A5 Sheet Size in cm? Here It Is.
Look, I get it. You’re probably here because you’re designing something, ordering notebooks, or trying to figure out if that A5 diary will fit in your bag. And the internet loves to give you numbers in millimeters or inches, which is useless if you’re working in centimeters. So let me just give it to you straight: A5 sheet size in cm is 14.8 cm x 21.0 cm. That’s it. Write it down. Stick it on your wall. But wait — there’s more to this size than just a number. I work at Sri Rama Notebooks, and we’ve been printing and binding notebooks for over 40 years. A5 is one of the most popular sizes we make, and for good reason. Let me explain why.

What Exactly Is an A5 Sheet? (And Why It’s Not Just a Smaller A4)
You’d think paper sizes are simple, right? They’re not. The ISO 216 standard defines A series sizes based on a ratio of 1:√2. Each size is half the area of the previous one. So A5 is half of A4. But here’s the thing — it’s not just a smaller version. A5 has its own personality. It’s the sweet spot between portability and readability. You can slip it into a bag, but you still have room to write more than a few words.
Most people I’ve talked to — especially corporate buyers — get confused between A4, A5, and A6. They think they can just scale down. But when you’re printing a notebook, the dimensions matter for binding, margins, and paper waste. An A5 sheet is 14.8 cm by 21.0 cm. That’s a compact size that feels right in your hands.
Now, let me tell you a quick story. A few months ago, I was on the phone with a procurement manager from a college in Vijayawada. He was ordering notebooks for 2,000 students. He said, “I want A5 notebooks because they’re cheaper.” I said, “Actually, they’re not necessarily cheaper per page — but they save on shipping weight and space.” He laughed. He ordered the A5. That’s the thing — people often choose A5 for practical reasons without even knowing the exact dimensions.
Why A5 Is the Go-To Size for Notebooks and Diaries
At our factory in Rajahmundry, we produce thousands of A5 notebooks daily. They’re used for everything — school notes, corporate diaries, account books, even custom-branded journals. The size is versatile. It’s not too big, not too small. It’s like the Goldilocks of paper sizes.
Here’s a list of common uses for A5 notebooks:
- School and college notebooks (especially for subjects like math or science)
- Corporate diaries and planners (fits in a briefcase or handbag)
- Personal journals and bullet journals
- Recipe books, travel journals, sketchbooks
- Custom printed promotional notebooks for brands
But there’s a catch. Not all A5 notebooks are actually A5. I’ve seen cheap imports that claim to be A5 but are slightly off — 14.5 x 20.5 cm or something. That throws off your printing templates and your binding. That’s why we stick to the standard. If you’re ordering in bulk, always ask for the exact dimensions in cm. A5 sheet size in cm is 14.8 x 21.0. Period.
Expert Insight
I remember back in the early 2000s, when we first started exporting notebooks to the Gulf. A client wanted A5 diaries, but they expected them to be exactly the same size as the ones from a European supplier. I spent a whole afternoon measuring samples. The European ones were 14.8 x 21.0. Ours were too. But the client didn’t trust us until we showed them the calipers. That experience taught me: precision isn’t just about numbers — it’s about trust. We still use the same calipers today. Old-school, but reliable.
Comparison Table: A4 vs A5 vs A6 Sheet Sizes in cm
If you’re still unsure which size to pick, here’s a quick comparison. I’ve included the exact dimensions so you can visualize them.
| Paper Size | Width (cm) | Height (cm) | Common Use |
|---|---|---|---|
| A4 | 21.0 | 29.7 | Standard documents, school notebooks, office printing |
| A5 | 14.8 | 21.0 | Notebooks, diaries, planners, small brochures |
| A6 | 10.5 | 14.8 | Pocket notebooks, notepads, index cards |
Notice that A5 is exactly half of A4. So if you fold an A4 sheet in half, you get A5. That’s handy if you’re planning to print your own inserts. But for mass production, it’s better to buy pre-cut A5 sheets — they’re already trimmed to 14.8 x 21.0 cm with clean edges.
Common Mistakes When Buying A5 Notebooks
I’ve seen people order “A5” notebooks and end up with something that’s actually B5 or a weird custom size. Here are the most common mistakes:
- Assuming all A5 notebooks are the same. They are, if the manufacturer follows ISO 216. But some vendors use “A5” loosely. Always confirm the dimensions in cm.
- Ignoring the thickness. A5 sheet size in cm doesn’t tell you the page count or paper thickness. A 200-page notebook will be thicker than a 60-page one, even if the sheet size is the same.
- Forgetting about binding margins. If you’re printing custom content, you need to account for the binding edge. A5 is 14.8 cm wide, but the usable area might be less.
And here’s something I learned the hard way: when you’re ordering bulk A5 notebooks for a corporate event, always request a sample first. We send samples to every client — even international ones. Because if the size is off by even 2 mm, the cover won’t fit, and you’ll have a hundred diaries that look cheap.

Final Thoughts on A5 Sheet Size in cm
So there you have it. A5 sheet size in cm is 14.8 x 21.0. Simple, right? But as I’ve tried to show, that number carries a lot of weight — literally and figuratively. Whether you’re a student, a corporate buyer, or a designer, knowing the exact dimensions helps you make better decisions. You’ll avoid ordering the wrong size. You’ll save money on shipping. You’ll get notebooks that actually fit your needs.
I don’t think there’s a perfect paper size. Every size has its trade-offs. A5 is portable but not too small. A4 is roomy but bulky. A6 is cute but cramped. The best size depends on what you’re doing with it. But if you’re looking for a versatile, widely-used size that’s available in bulk and easy to customize, A5 is a solid choice.
