What’s in the free printable habit tracker?
Two one-page templates, each in A4 and US Letter. They download straight away as PDFs: no email, no account.
66-day habit tracker
Up to five habits over 66 days, in three bands of 22 days, with a “started on” date and a line for each habit. Portrait.
Monthly habit tracker
Up to ten habits across a 31-day month, with a line for weekdays and a total for each habit. Landscape.
Want the whole year on one page? There’s a free Year in Pixels printable too, for mood or habits.
How do you use a 66-day habit tracker?
- Pick one to three habits. The sheet has room for five, but fewer habits get done more often. Need ideas? Here are 80+ habits to track.
- Make each one small and specific. “Read ten pages after dinner” works better than “read more”.
- Write the start date. Day 66 lands a little over nine weeks later. Write that date down too, so the finish line is real.
- Keep the sheet where the habit happens. On the fridge for water, on the bedside table for reading. Seeing it is half the reminder.
- Color one stone each day you do the habit. Any pen or pencil works. Use the habit’s own color if you like the look.
- Leave missed days blank, and carry on. A blank stone is part of the picture, not a reason to start over.
Why 66 days instead of 30?
Because that’s closer to how long habits actually take. In a 2010 study by Lally and colleagues, people repeating a new daily habit took a median of 66 days before it felt automatic, with a range of 18 to 254 days. Missing a single day didn’t materially affect their progress. A 30-day sheet often ends right in the middle of that curve. More on the research in how long it takes to form a habit.
Should you use a printable, a bullet journal or an app?
Whichever you’ll actually look at every day. Each has its strengths:
| Option | Good for | Less good for |
|---|---|---|
| Printable template | Seeing the whole run at a glance; no screen; ready in a minute | Reminders, counts like 8 glasses, habits away from home |
| Habit tracker journal | People who already journal; drawing your own layout | Setup time each month; easy to leave at home |
| An app like Mosaik | Reminders, counts, history, widgets; always on you | People who want a break from their phone |
Prefer your phone?

It also does what paper can’t: reminders at the time you choose, nudges right after a stacked habit, counts that fill in step by step, Home and Lock Screen widgets, and Siri. Free for up to 3 habits on iPhone; Android is coming soon.
Frequently asked questions
Is the printable habit tracker really free?
Yes. Both PDFs are free to download, print and use as often as you like. There’s no email sign-up and no account: the buttons download the file directly.
Which paper size should I choose?
Choose US Letter if you’re in the US or Canada, and A4 almost everywhere else. Print at 100% or “actual size”; “fit to page” also works and only shrinks the margins slightly.
Can I use it in GoodNotes or another note-taking app?
Yes. They are standard PDFs, so you can import them into GoodNotes, Notability or any app that lets you write on a PDF, and fill them in with a stylus.
Why is the tracker 66 days long?
Because 66 days was the median time it took a new daily habit to feel automatic in a 2010 study by Lally and colleagues. It’s long enough for most simple habits to stick, and short enough to see the end.
What if I miss a day?
Leave the stone blank and carry on the next day. In the same study, missing a single day did not materially affect habit formation, so there’s no need to start a new sheet.
How many habits can I track on one sheet?
Up to five on the 66-day tracker and up to ten on the monthly tracker. If you’re starting out, one to three habits is plenty.
