The Ultimate Planner Cover Size Guide: How to Choose Between A5, A6, and Weeks
Choosing the right planner cover starts with understanding how you use your notebook every day. Some people want more space for journaling and detailed planning, while others prefer a slimmer format that slips easily into a bag and travels well.
At ABIGALECrafts, we’re often asked about the difference between A5, A6, and Weeks planner covers. If you use Hobonichi, Stalogy, Midori, or similar notebooks, this guide will help you understand the dimensions, compatibility, and everyday feel of each size.
Quick Comparison: A5 vs A6 vs Weeks Dimensions
Before choosing a planner cover, it helps to compare the standard insert sizes and the kind of planning each format suits best.

|---|---|---|---|
| A5 | 148 × 210 mm | Hobonichi Cousin, Stalogy 365 A5, Midori MD A5 | Detailed planning, journaling, desk use, memory keeping |

A5 Planner Covers: Best for Detailed Journaling and Planning
An A5 planner cover is designed for notebooks that measure 148 × 210 mm. Among the three sizes, it offers the most writing space and is often the best fit for people who like to keep everything in one place.
A5 works especially well if you:
- write longer daily entries or reflections
- combine planning, journaling, and note-taking in one notebook
- use stickers, inserts, or decorative pages
- prefer a planner that stays mostly at home, in a studio, or on a desk
For many people, A5 feels the most spacious and comfortable for slow planning sessions. If you use a Hobonichi Cousin or a similar large-format notebook, an A5 cover is usually the most practical choice.
A6 Planner Covers: A Balanced Everyday Choice
An A6 planner cover fits notebooks measuring 105 × 148 mm. This size is often chosen by people who want a planner that is easy to carry while still offering enough room for daily writing.
A6 is a strong option if you:
- carry your planner with you throughout the day
- write short daily entries, lists, or appointments
- want something compact without feeling too limited
- prefer a notebook that fits easily into a handbag, tote, or backpack
If A5 feels too large and Weeks feels too narrow, A6 is often the middle ground. It suits many everyday planning routines and is a popular size for Hobonichi Original users.
Weeks Planner Covers: Slim, Light, and Easy to Carry
A Weeks planner cover is made for slim notebooks measuring 94 × 187 mm. This format is well suited to people who prefer a lighter planning setup and a more compact weekly layout.
Weeks may be the best fit if you:
- plan mostly by the week rather than writing long daily entries
- prefer a slim notebook that takes up very little space
- want a planner for schedules, habit tracking, budgeting, or task lists
- carry a smaller everyday bag or travel light
Because the Weeks format is tall and narrow, the cover should feel slim and easy to use rather than bulky. For people who like minimal planning tools, Weeks often feels simple and practical in the best way.
How to Choose the Right Planner Cover Size
If you are still deciding between A5, A6, and Weeks, these questions can help narrow it down.
How much do you write each day?
If you write a lot, A5 gives you the most freedom. If you keep shorter notes or simple plans, A6 may be enough. If your planning is brief and weekly, Weeks can work very well.
Where do you usually use your planner?
If your notebook mostly stays on a desk, A5 is often the easiest to enjoy. If you carry it with you throughout the day, A6 or Weeks may be more practical.
Do you prefer detailed planning or a lighter setup?
A5 suits people who want room for everything. A6 suits people who want balance. Weeks suits people who want a clean, lightweight planning format.
Why Fabric Planner Covers Feel Different
Size affects function, but material affects experience. A fabric planner cover offers a softer, warmer feel in daily use and brings texture to your planning routine in a way that feels personal and easy to live with.
Many people choose fabric covers because they feel less formal than leather and more natural in everyday life. They pair well with quiet routines like morning planning, evening journaling, or carrying a favorite notebook from place to place.
Frequently Asked Questions
Will these planner covers fit a notebook with a plastic Cover on Cover?
Fit can vary depending on the notebook and the added thickness of the plastic cover. In most cases, it is best to check the product details carefully before purchasing, especially if you prefer a snug fit.
Is A5 or A6 better for beginners?
A6 is often easier for beginners because it feels more approachable and portable. A5 is a better choice if you already know you want extra writing space for journaling, planning, or creative layouts.
Are Weeks planner covers good for travel?
Yes. Weeks planner covers are a popular choice for travel and commuting because they are slim, lightweight, and easy to carry in smaller bags.
How do I care for a handmade fabric planner cover?
Gentle spot cleaning with a soft damp cloth is usually the safest option. If your cover uses delicate fabric or detailed stitching, avoid harsh washing methods and follow any care guidance provided on the product page.
Find the Right Fit for Your Routine
The best planner cover is the one that fits naturally into your daily life. If you want more room to write, A5 may be right for you. If you want something easy to carry every day, A6 may be the better choice. If you prefer a slim weekly format, Weeks is often the most convenient option.
