Louis Vuitton Planner Sizes Explained: PM, MM, GM and What Inserts Actually Fit
If you have a Louis Vuitton agenda (or you are shopping for one), you have probably seen people describe sizes as
“small, medium, and large,” and then you go online and suddenly everything is labeled A6, Personal, PM, MM, GM, and now your brain is melting.
This guide is the straight-talk version. No guessing, no “it should fit,” no surprise paper sticking out the side of your agenda when you close it. We’ll cover the LV size names (PM, MM, GM), the insert sizes that match, and the biggest trap of all: the A6 problem.
First, the simple translation: LV sizes to insert sizes
Traditionally, Louis Vuitton agendas used PM, MM, and GM. Many shoppers now use “small, medium, large” instead, but the matching insert sizes are still the same.
| Louis Vuitton size name | What people call it now | Insert size that matches |
|---|---|---|
| PM | Small | |
| MM | Medium | Personal |
| GM | Large | A5 |
If you only remember one thing from this post, remember this:
Pocket = PM, Personal = MM, A5 = GM.
What “Pocket,” “Personal,” and “A5” actually feel like in real life
Pocket (PM, Small)
Pocket is the tiny powerhouse. Great if you want something truly compact, wallet-friendly, and minimal. It’s ideal for appointments, short lists, on-the-go planning, and people who do not want to carry a full notebook situation around town.
Personal (MM, Medium)
Personal is the sweet spot for most people. You get more writing room than Pocket, but it is still portable. If you want a daily life planner without feeling like you are hauling a textbook, this is usually the winner.
A5 (GM, Large)
A5 is the “I want space” size. More room for writing, more room for planning, more room for notes. It’s fantastic for desk planning, work planning, and anyone who likes a layout that breathes.
The biggest problem online: A6 vs Personal size
Now for the part that causes the most wasted money and frustration.
True A6 is an international paper size that has existed for over 100 years. It is literally half of an A5.
But on Amazon and Etsy, you will often see Personal size inserts labeled as “A6.” They are not true A6. This is why some people order “A6 refills,” they arrive, and nothing fits the way they expected.
What to do instead: always check the exact measurements
It is totally fine to click an A6 listing, just do not trust the label. Trust the numbers. Many insert makers know this problem is everywhere, so you will often see the phrase “True A6” used when it is actually the international A6 size.
For reference, my True Personal Size insert measurements are 3.74 x 6.73 inches (95 x 171 mm). If you see “A6” but the measurements are around that, you are looking at Personal size, not True A6.
Franklin Covey Compact vs Personal Wide in an MM agenda
This is one of the most confusing areas for Medium (MM) Louis Vuitton users, especially if you feel standard Personal size is a little narrow.
Franklin Covey Compact (what actually works)
Franklin Covey Compact inserts are slightly wider than standard Personal size at approximately 4.25 x 6.75 inches.
These are designed for the same 6-ring Personal hole spacing and will work inside a Louis Vuitton MM agenda. Many people choose Franklin Covey Compact (also known as FCC) size specifically because they want more writing space without moving up to a larger planner.
The downside is availability. Compact inserts can be harder to find outside of Franklin Covey, and most independent insert makers (including us) focus on standard Personal size.
Personal Wide (what does NOT work)
Personal Wide is where people run into trouble.
Personal Wide inserts use the same hole spacing as Personal, and they are usually the same height, so when the agenda is open, everything looks like it fits perfectly.
But once you close the agenda, the extra width (4.75″ across) causes the paper to stick out past the edge. The rings push the pages outward, and the snap closure will not close properly.
If you are using a Louis Vuitton MM and want it to close cleanly, stick with standard Personal size or Franklin Covey Compact. Personal Wide will not work in a snap-closure LV agenda.
Ring spacing basics: most ring mechanisms are standard
In my experience (and I’ve been making planner inserts for a long time), the majority of ring mechanisms are pretty standard within the common sizes. Binders themselves can vary, covers can vary, brands can vary, but the ring spacing is usually consistent.
This is why inserts from different shops often fit the ring mechanism, but the paper size can still be wrong. Ring spacing is only half the story. Width and height matter too, especially with snap closures.
Quick spacing checks you can measure
- Pocket: typically 6 rings, evenly spaced, often about 19 mm between rings
- Personal: two sets of 3 rings, about 19 mm within each set, with about 2 inches between the top set and bottom set
- A5: same idea, about 19 mm within sets, with about 2.75 inches between the sets
If someone is confused about whether they have Personal size or they accidentally bought “A6” that is really Personal, measuring that middle gap is the fastest clue.
How to measure your agenda and inserts in 60 seconds
- Measure the paper size first.
Grab a ruler or tape measure and measure the width and height of the inserts you already have. - Then measure the middle ring gap.
Look at the rings — you’ll see a top group of 3 and a bottom group of 3 (for Personal and A5). Measure the distance between those two groups. - Compare your numbers to standard sizes.
If your insert size and your ring gap match Personal, buy Personal. If they match A5, buy A5. If something is “A6” but it matches Personal measurements, treat it as Personal.
If a listing does not show measurements, that is a red flag. Measurements should be normal information, not a mystery novel.
What fits a Personal ring mechanism (and what that does not guarantee)
A Personal ring mechanism can often accept multiple paper sizes that share the same hole punching pattern, including standard Personal, some Franklin Covey formats, and even certain B6 ring inserts that are punched to the Personal ring array.
But here’s the reality check: hole punching compatibility does not guarantee closure compatibility. LV agendas are especially picky because the snap closure makes paper width matter a lot more than it does in a plain ring binder.
Now that you know what fits, here’s where to start
Once you have your size figured out, the next step is building out what goes inside your agenda. You can browse all of our inserts and refills here: Planner Insert Refills. From there, choose either Calendars or Functional Pages depending on what you need.
A lot of customers begin with a calendar refill, then add functional pages once they know what they actually use week to week. That is the smart way to build a planner that fits your life, not a fantasy version of your life.
If you ever feel stuck between two sizes, measure first, then choose. It saves money, time, and frustration.
Quick recap
- Pocket = PM = Small
- Personal = MM = Medium
- A5 = GM = Large
- True A6 is not Personal — always check measurements
- Personal Wide can look like it fits an MM agenda until you close it
- Measure the middle ring gap if you are unsure
Questions I get asked constantly
Does Louis Vuitton still use PM, MM, GM?
Many shoppers use Small, Medium, Large now, but PM, MM, GM are still the common size references people search for. If you are buying refills, matching the insert size matters more than the name.
Why do so many listings call Personal size “A6”?
Because it became common shorthand online, but it is inaccurate. True A6 is a real international paper size. The safest move is always to check the measurements in the listing.
Can I use Personal Wide or B6 inserts in my LV MM agenda?
No. Personal Wide and B6 inserts may fit on the rings because the hole spacing is the same, but the extra width means the paper will stick out past the edge of the agenda. As soon as you try to close the snap, it will not close properly. Stick with standard Personal size or Franklin Covey Compact if you want your MM to close cleanly.
I bought the wrong size. Now what?
If you ordered from us, email us and we can do an exchange. We will talk you through what size you actually have so you get the right one the second time around. It is always a good idea to check any existing inserts you have in your agenda before reordering — that way we can match from what you already know works.
What is the easiest way to tell what size my binder is?
Measure the center ring gap — that is the distance from the center of the top group of rings to the center of the bottom group. If there is no gap at all and the rings are evenly spaced, you have a Pocket size. If the gap is about 1.5 inches, it is True A6. If the gap is about 2 inches, it is Personal. If the gap is about 2.75 inches, it is A5. That one measurement will tell you more than any label will.
