M5 Planner Refill Sizes Explained: 62 mm vs 74 mm Width

M5 is a compact ring-planner format, but the label alone does not guarantee that every refill will fit the same cover. The most useful number to check is the page width.

Why M5 refill width matters

Two M5 refill pages can share a five-hole format and still sit differently inside a planner. A narrower page leaves more room around the rings and is useful when you prefer a compact layout. A wider page gives you more writing space, but can feel close to the cover edge in a slim binder.

At Kozy Lumiere, you will see compact M5 options around 62 x 105 mm and wider options around 74 x 105 mm. The height may be similar, while the usable writing area changes noticeably.

62 mm wide M5 refills

Choose a 62 mm width when you want a genuinely small, portable planner setup. It works well for short daily notes, quick lists, spending logs, habits and simple schedules. This size is especially helpful when you carry your planner in a small pouch or bag.

74 mm wide M5 refills

Choose a 74 mm width when you want more room for a weekly plan, longer notes, decorative journaling or a fuller layout. It can be a better fit for people who enjoy the M5 format but do not want to write in a very narrow column.

Check these three things before ordering

• Measure the refill you already use. Check width and height, not just the word M5.
• Compare the hole pattern. Your insert must match your ring spacing and hole count.
• Think about your planner cover. A slim cover, a zip pouch and a larger ring binder can all leave different amounts of room around the page.

A simple way to build an M5 setup

Start with one refill style for your everyday planning, then add a second only when you need it. A narrow blank or grid refill can handle lists and notes; a wider refill can become your weekly dashboard or creative page. Dividers, pockets and release paper can keep the small format organized without making it bulky.
