How to Make Your 30-Day Habit Tracker

Name the habit. Type the one habit this sheet is for, or leave it blank and write it in by hand.
Pick the length. 30 days, or 21, 66, 75, 90 or 100.
Choose the paper and the look. US Letter, A4, A5 or Half Letter, circles or squares, in one of six themes and any colour.
Download the PDF or print. Write your start date on the sheet and cross off the first box.

The file is made in your browser. Nothing you type is uploaded.

What Is on the Sheet

Thirty large numbered boxes, a line for the habit and another for the start date. Because the boxes are numbered and not dated, you can begin on any day of the month: cross off box 1 on the first day and keep going.

Under the boxes there is room for notes and a key with three marks: done, did my minimum, and missed. You can also add lines for why the habit matters to you and the smallest version of it, plus a reward at the end.

Why 30 Days

Thirty days is long enough to feel real and short enough to see the end of from day one. It is a commitment device, not a law of nature. In a University College London study, a new habit took 66 days on average to feel automatic, and anywhere from 18 to 254 days depending on the person and the habit. See how long it takes to form a habit for the detail.

So treat day 30 as a checkpoint. If the habit still takes effort, print a second sheet.

Other Challenge Lengths

The same sheet comes in five other lengths. Twenty-one days is the classic short challenge, and it pairs with 90 days in the 21/90 rule. Sixty-six matches the average from the study above. Seventy-five fits the 75 Hard challenge. Ninety covers a quarter, and one hundred is for the long haul.

Two to a Sheet, or Ticked on Screen

Running two challenges at once, or doing one with a friend? On Letter or A4, switch on "Two on one sheet" for two half-size trackers with a dashed line to cut along.

For a tablet or a computer, switch on "Fillable PDF". Each day can then be ticked in a PDF app, and the file still prints the same.

What to Do When You Miss a Day

You will miss one. Decide in advance what your minimum is, such as two minutes of the habit, and write it on the sheet. On a hard day, do the minimum and mark the box with a slash. If you miss a day completely, leave the box empty and do the next one; one empty box in thirty is still a good month.

Six Looks for the Same Challenge

Tap a picture to put that look on your sheet. Your habit and settings stay as they are.

Frequently Asked Questions

Is this 30-day habit tracker printable free?

Yes. There is no account and no email step. The PDF is made in your browser, so nothing you type is uploaded.

Can I change the number of days?

Yes. The challenge sheet comes in 21, 30, 66, 75, 90 and 100 days. Ready-made PDFs for each length are on this page.

Does it track more than one habit?

No. A challenge sheet is for one habit, which is the point of a challenge. For several habits at once, use the monthly or weekly sheet.

Do I have to start on the first of the month?

No. The boxes are numbered 1 to 30, not dated. Write your start date on the line at the top and begin any day.

Can I get circles instead of squares?

Yes. Choose Circles or Squares under More options. The ready-made 30-day sheet uses circles.

Does it take 30 days to form a habit?

Not reliably. In a University College London study the average was 66 days, and people ranged from 18 to 254, so treat thirty days as a first target.

Can I tick the days on screen?

Yes. Switch on Fillable PDF before you download, or take the ready-made fillable sheet on this page. Each day can be ticked in a PDF app such as Adobe Acrobat Reader, and the file still prints normally.
