Best A5 Planner: Daily, Weekly Vertical and Undated Picks
Quick answer: The best A5 planner for daily writing and journaling is the 2027 Daily A5 Magnet Planner: 148×210×20mm, 544 pages, and white 52gsm New Sanzen paper in a lay-flat sewn book. Choose the 2027 A5 Weekly Vertical for time blocking, the Undated Daily A5 for flexible daily starts, or the Undated Weekly Horizontal A5 for a lighter week-at-a-glance system.
A5 is a strong desk-to-bag planner size: large enough for journaling, detailed schedules, stickers, and memory keeping without moving to a full letter-size book. Aura Estelle Magnet Planners are designed in Canada and made in Japan by a manufacturer with more than 80 years of experience.

A5 vs A5 Wide vs B6
| Size | Aura Estelle measurement | What it means in a planner setup |
|---|---|---|
| A5 | 148×210mm | The bound Magnet Planner size and the best default for generous writing room, daily journaling, and desk-forward planning. |
| A5 Wide / A5W | 178×218mm for Aura Estelle inserts | A wider ring-insert format, not the same size as an A5 Magnet Planner. It is 30mm wider and 8mm taller than Aura’s A5 book, so covers and inserts are not interchangeable. |
| B6 Magnet Planner | 128×182mm | More portable than A5 while keeping daily or weekly structure. Choose B6 when carry comfort matters more than maximum writing area. |
A5 Wide is not one universal international book size. The 178×218mm number above is Aura Estelle’s published insert measurement; always match a ring cover or insert to its exact product page.
What A5 shoppers also compare
| Planner | Verified size and format | Choose it when |
|---|---|---|
| Aura Estelle 2027 Daily A5 | 148×210×20mm; 544 pages; daily pages in a minimal Monday-start system | You want high daily writing capacity, no printed holidays, sewn binding, and North American fulfillment. |
| Hobonichi Cousin | 148×210mm A5; one page per day plus vertical weekly pages | You want the established Hobonichi format and cover ecosystem. The distinction here is layout and ecosystem, not a paper-superiority claim. |
| Leuchtturm1917 Weekly Planner Medium | 5.75×8.25in on the current US listing; 18 months, July 2026–December 2027 | You want a familiar hardcover weekly book with seven days to a page and broad notebook-brand availability. |
| Moleskine Classic Large | 5×8.25in; smaller in width than true A5 | You want wide retail access, hard- or soft-cover choices, and a familiar compact format. Do not assume “Large” means ISO A5. |
Choose a cover after the planner
Match the book size and thickness before choosing a cover. The 20mm Daily needs more spine room than the 15mm Weekly Vertical or 12mm Weekly Horizontal. Start with Aura Estelle planner covers, then read each product’s fit notes for the exact planner, clear cover, stickers, and anything else in your planner stack.
