How to find the right Planner Refills AI guide

Written by an AI model from its trained knowledge.

What the AI looks for in Planner Refills

Ring or disc standard
Match the hole count, hole spacing and paper size of your binder (Filofax Personal, Pocket and A5 differ in each); for disc systems, match the punch shape. The same nominal size can use different hole patterns across brands.
Brand-specific bound refills
For bound-book covers, buy the refill made for that cover's year and size (for example the yearly Hobonichi book or a Traveler's Notebook insert). Only the matching refill sits correctly in the cover's sleeve or bands.
Dating
Choose dated refills for the right year and start month, or undated refills if you skip weeks. Undated refills avoid wasted pages but require writing in the dates yourself.
Paper weight
Check the paper's suitability for fountain pens or markers if you use them. Cheap refills often bleed with the pens the original planner handled well.

Brands that matter

  • Filofax: Dated and undated refills for its ring sizes.
  • Hobonichi: Yearly Techo books that fit its covers.
  • Traveler's Company: Diary and notebook inserts for Traveler's Notebook covers.
  • The Happy Planner: Disc-punched refill packs for its sizes.
  • Day-Timer: Long-running refills for its ring-bound organizers.

What to avoid

  • Refills described only by paper size with no hole spacing given.
  • Buying a dated refill late in the year without checking that it covers the coming year.

Questions

Can I punch my own refills?

Yes, with an adjustable ring punch or the matching disc punch, which lets you use any paper you like.
