How it works

Three steps to a printable number line

  1. Set the numbers

    Enter the start and end, then the step between labelled ticks. Add small ticks in between, or switch to fractions and pick a denominator.

  2. Lay out the page

    Choose 1 to 10 lines per page, US Letter or A4, landscape or portrait, and whether to print labels, arrows, cut lines and a name line.

  3. Download and print

    Download the PDF and print at Actual size (100%). Every tick on a line is the same distance apart.

Ideas

Integer number lines for adding and subtracting

A number line from −20 to 20 is long enough for most integer problems in grades 6 and 7, such as −8 + 13 or 4 − 15, without running off the end.

Negative numbers are printed with a proper minus sign, and every tick is the same distance apart, so students can count jumps accurately.

FAQ

Questions teachers ask

Can I make number lines from −10 to 10 instead?

Yes. Change Start to −10 and End to 10. Any whole-number range works, up to 50 steps on one line.

How many number lines fit on a page?

From 1 to 10. Six per page on landscape paper is a good size for strips students keep on their desk; choose 4 if you want larger numbers.

Is the number line generator free?

Yes. There is no account, no sign-up and nothing to buy.

How do I print it at the right size?

Open the PDF and print at Actual size or 100%, not Fit to page. Choose the same paper (US Letter or A4) in the generator and in your printer settings.

Can I make blank number lines for students to fill in?

Yes. Set Labels to None for ticks only, or Endpoints only so just the first and last numbers are printed.

Does it work on a Chromebook, iPad or phone?

Yes, in the web browser. On iPhone or iPad, Safari may open the PDF instead of downloading it: tap Share, then Print or Save to Files.

Is anything uploaded?

No. The number lines and the PDF are made on your device. The tool uses no cookies, analytics or ads.
