Choosing a leather journal isn’t just about colour or leather type — size is the first decision that shapes how you’ll actually use it. A journal that’s too large may stay on your desk. One that’s too small might feel limiting. If you’ve ever wondered which size makes the most sense for your routine, this guide will help you confidently choose between A5, A6, and pocket leather journals.
Why Journal Size Matters More Than You Think
The right journal size fits naturally into your daily life. It affects how often you write, where you carry it, and how comfortable it feels to use. Before you think about leather finishes or page styles, narrowing down the right size makes every other decision easier.
Most people fall into one of three categories: those who write primarily at a desk, those who write on the move, and those who want something ultra-minimal. That’s where A5, A6, and pocket journals each shine.
A5 Leather Journals: The Most Versatile Choice
A5 leather journals are the most popular size for a reason. They offer a generous writing area without feeling bulky, making them ideal for everyday writing, work notes, and longer reflections.
If you typically write at a desk, café table, or quiet workspace, A5 gives your hand room to move comfortably. Full sentences, sketches, planning layouts, and journaling spreads all feel natural at this size.
Many people choose A5 as their “main” journal — something that stays within reach throughout the day and becomes part of a consistent writing habit. If you want a size that works for almost everything, A5 is usually the safest starting point.
A6 Leather Journals: Compact and Easy to Carry
A6 leather journals are designed for mobility. Smaller and lighter than A5, they fit easily into a daypack, crossbody bag, or jacket pocket without demanding extra space.
This size works especially well for travel, commuting, and everyday carry. You can capture ideas, lists, and short reflections wherever you are — on a train, standing in line, or during a quick break.
While the page is smaller, many writers enjoy how A6 encourages focused, concise entries. It removes the pressure to fill large pages and makes journaling feel more approachable.
Pocket Leather Journals: Minimal and Ultra-Portable
Pocket leather journals are the most compact option. Designed to disappear into a pocket or small pouch, they’re best suited for quick notes rather than extended writing sessions.
If you prefer jotting down reminders, ideas, or short observations throughout the day, a pocket journal keeps things simple. It’s a practical choice for minimalists or as a secondary notebook alongside a larger journal.
Because of the limited space, pocket journals work best when you already know you don’t need room for long entries.
Which Leather Journal Size Is Right for You?
If you’re deciding between sizes, think about how and where you write most often:
- Choose A5 if you write regularly at a desk, enjoy longer entries, or want one journal that does it all.
- Choose A6 if you write on the go, travel often, or want something you can carry daily without thinking about it.
- Choose pocket if you prefer ultra-minimal notes and maximum portability.
Many people eventually use more than one size — an A5 at home or work, and an A6 or pocket journal for travel and daily carry.
Starting with the Right Size Makes Everything Easier
