My Buying Guides on A5 20 Hole Notebook
When I first started looking for an A5 20 hole notebook, I realized there are quite a few factors to consider to find the perfect one for my needs. Here’s what I learned from my experience that might help you choose the right notebook too.
Understanding the A5 Size
I found that A5 notebooks are a great balance between portability and writing space. The size (about 5.8 x 8.3 inches) fits perfectly in my bag without being bulky, yet offers enough room for notes, sketches, or planners. Make sure the notebook truly matches the standard A5 dimensions so it fits your existing folders or binders.
Why 20 Holes Matter
The 20-hole format was new to me at first. It’s a bit different from the more common 6 or 9-hole notebooks. The 20 holes provide a secure binding and allow the notebook to fit into specialized A5 ring binders. I recommend checking if your binder supports 20 holes before buying. This feature is particularly useful if you want to add or remove pages easily.
Paper Quality and Weight
For me, the feel of the paper is crucial. I prefer smooth paper that works well with pens, pencils, and even markers without bleeding through. I usually look for paper weights between 80-100 gsm. Thicker paper means less ghosting and better durability, which is important if I’m using both sides of the page.
Binding Style and Durability
Since the 20 holes allow for ring binding, I checked whether the notebook had a sturdy cover and strong rings. A durable cover protects the pages and makes the notebook last longer, especially if you carry it around daily like I do. Some notebooks come with hardcovers, others with flexible plastic or cardboard covers — choose what suits your style and usage.
Page Layout Options
I prefer lined pages for writing, but some A5 20 hole notebooks offer dotted, grid, or blank pages for drawing or bullet journaling. Think about how you’ll use the notebook. If you want versatility, some brands offer refillable pages or mixed layouts.
Additional Features to Consider
From my experience, small extras can make a big difference. Look for notebooks with:
- Perforated pages for easy tearing
- Pockets or folders inside the cover for loose papers
- Page markers or elastic bands to keep the notebook closed
- Numbered pages for better organization
Price and Brand Reputation
Finally, I compared prices and read reviews from other users. Some premium brands offer high-quality notebooks with great features but at a higher cost. Depending on your budget, you can find affordable options that still meet your needs. I recommend buying from reputable brands or stores to ensure quality.
Choosing the right A5 20 hole notebook depends on your personal preferences and how you plan to use it. From size and hole count to paper quality and extra features, I hope my buying guide helps you make an informed decision. Happy note-taking!
