Planner Size Guide: Pocket vs A5 vs A6 and How to Choose

Planner Size Guide: Pocket vs A5 vs A6 and How to Choose

The best planner size is the one that fits both your plans and the places you will actually use it.

Choose a Pocket planner for quick notes and everyday carry, A6 when you want a compact planner with a little more writing room, and A5 when you want space for detailed weekly planning, trackers, and multiple life categories. Before buying inserts, always check the exact page measurements and hole pattern: planner size names are not perfectly consistent across brands.

Quick Planner Size Chart

A5 and A6 are ISO paper sizes. “Pocket” is commonly used by planner brands, but its exact dimensions can vary. Treat the measurements on the product page as more important than the size name.

Why Planner Size Names Can Be Confusing

Planner shopping involves two overlapping systems:

• Paper standards, including A5 and A6, have defined dimensions.
• Planner-brand sizes, including Pocket, Personal, Mini, Classic, and Compact, can vary between sellers.

Two products called Pocket may not use identical paper or hole spacing. A page may physically fit inside a cover but still fail to turn comfortably or line up with the rings.

When comparing planner inserts, check:

• finished page width and height;
• number of holes;
• distance between hole centers;
• space between the holes and the page edge;
• usable writing area after the punched margin.

Pocket Planner Size

JoyJoy Pocket Planner Inserts measure 80 x 120 mm and use six holes.

Pocket works best as a companion for information you want close at hand:

• today's top priorities;
• quick tasks and reminders;
• a short workout log;
• spending notes;
• lists you need while away from your desk;
• ideas you do not want to lose.

Its strength is not fitting an entire life-management system onto one tiny page. Its strength is being easy to carry and quick to use.

Choose Pocket if:

• you want a planner that fits in a small bag;
• you usually write short notes or lists;
• you want a portable companion to a larger planner;
• a large blank page makes planning feel like work.

Pocket may feel too small if:

• you write large;
• you need an hourly schedule;
• you want long-form journaling;
• you prefer to see many projects and categories at once.

A6 Planner Size

A6 paper measures 105 x 148 mm. It sits between Pocket and A5: compact enough to carry regularly, but large enough for more comfortable daily and weekly layouts.

Choose A6 if:

• Pocket feels cramped but A5 feels bulky;
• you want a compact main planner rather than a quick-capture companion;
• you need moderate room for appointments, tasks, and notes.

A6 can be an excellent middle ground, but compatibility still depends on the binder and hole pattern, not only the paper dimensions.

A5 Planner Size

A5 paper measures 148 x 210 mm, half the size of A4 paper.

It gives you significantly more room for detailed planning and is one of the most flexible sizes for building a modular system with different inserts.

Choose A5 if:

• you want detailed weekly or daily planning;
• you use trackers, project pages, or longer notes;
• your planner mostly stays on a desk or travels in a larger bag;
• you want one main system for several areas of life.

A5 may feel too large if:

• you want to carry it everywhere;
• you only need a few short reminders;
• too much page space encourages you to over-plan.

Pocket vs A6 vs A5

There is no universally superior size. A planner that technically offers more space is not more useful if it stays at home when you need it.

Five Questions to Help You Choose

1. Where will you use it?

If the planner needs to travel everywhere, test whether it fits your everyday bag. If it will mostly stay on your desk, prioritize writing comfort.

2. What will you write in it?

Short priorities and reminders need less room than time-blocking, journaling, or project planning.

3. How large is your handwriting?

Print or draw the page dimensions at full scale and write a sample list before buying.

4. Do you want one planner or a companion system?

Pocket can work beautifully as a companion for quick capture while A5 holds detailed plans and reference pages.

5. Will the inserts actually fit?

Confirm exact measurements and hole spacing. Similar names do not guarantee compatibility.

Try the Size Before You Buy

The simplest test is to make a full-scale paper sample:

• draw or print the exact page dimensions at 100% scale;
• trim the sample;
• write a realistic daily list;
• place it in your usual bag;
• compare how it feels at your desk and while standing.

This small test can tell you more than looking at size names online.

Frequently Asked Questions

Is Pocket planner size the same as A7?

Not necessarily. A7 is a defined ISO paper size of 74 x 105 mm. Pocket is a planner-market name whose measurements can vary by brand. JoyJoy Pocket inserts measure 80 x 120 mm.

Is A5 too big to carry every day?

It depends on your bag and planning habits. A5 is comfortable for detailed writing, but Pocket or A6 may be easier if you use a small bag or plan while moving around.

What planner size is best for beginners?

Choose based on the simplest planning habit you want to maintain. Pocket is approachable for short lists, A6 offers a compact middle ground, and A5 gives beginners room to experiment with several layouts.

Can inserts from different planner brands be mixed?

Sometimes, but confirm page measurements, number of holes, and hole spacing first. A matching size name does not guarantee a matching punch pattern.

Should I use more than one planner size?

Only when each size has a clear job. For example, Pocket can hold quick notes and daily priorities while A5 holds detailed weekly plans, projects, and reference pages.
