An M5 planner—also called Mini 5—is a tiny five-ring refillable planner for short lists, quick notes and focused trackers. JoyJoy M5 inserts measure 67 × 105 mm, but M5 naming is not universal between brands, so match the page size and hole layout before buying refills.
Small, repeatable planning jobs
To-do lists, grocery lists, expense notes, habit checks and one-day schedules.
Long-form or crowded layouts
Long journaling, large handwriting and full weekly dashboards usually need more page space.
What can you use an M5 planner for?
M5 works best when each page has one clear job. Use it for a short daily list, a compact schedule, expenses, groceries, habits, sleep notes or another tracker you update in seconds. If you want longer task names or a roomier weekly view, compare M5 with A7/Pocket before choosing.
How big is an M5 planner?
“M5” usually describes the refill format, not one universal outside cover size. JoyJoy M5 pages are 67 × 105 mm. A finished binder is larger because it also needs space for the rings, cover edges and closure; the exact outside dimensions depend on the cover style.
How to check whether M5 refills will fit
- Measure a page that already fits from finished edge to finished edge.
- Count the rings and holes. JoyJoy M5 uses five.
- Measure the hole diameter. JoyJoy M5 holes are 4 mm.
- Measure center to center between adjacent holes. JoyJoy spacing is 19 mm.
- Check cover clearance. The page should turn without rubbing the cover or closure.
What pages should you start with?
Start smaller than you think: one monthly overview, one weekly or daily page, one tracker and one flexible notes or list page. That is enough to learn what you actually use before adding more sections. The M5 inserts starter setup walks through a practical four-part system, while M5 habit tracker ideas shows focused ways to use the tiny format.
Choose the M5 system one layer at a time
Start with the physical format, then add only the pages and storage pieces that match it.

M5 planner FAQ
Is M5 the same as Mini 5?
At JoyJoy, yes: M5 and Mini 5 refer to our 67 × 105 mm five-hole insert format. Other brands can use different measurements, so compare the specification before mixing covers and refills.
Is M5 the same as A8?
Not always. Some sellers use M5 and A8 together, but the names do not guarantee the same finished page size or hole pattern. Measure both before ordering.
Is M5 good for everyday carry?
Yes, if you want a tiny planner for short entries and quick capture. It is less suitable for long journaling, large handwriting or a detailed weekly spread.
How many sheets fit in an M5 binder?
There is no universal sheet count because ring diameter, paper thickness and added pockets or dashboards all affect capacity. Use the specific cover's ring measurement and avoid packing pages so tightly that they stop turning freely.
Can M5 inserts fit an A7/Pocket binder?
JoyJoy M5 sheets can sit on five aligned rings in a JoyJoy A7/Pocket binder because both use 19 mm adjacent-hole spacing; one A7 ring remains unused and the page sits smaller inside the cover. Check other brands separately.
