Printable Number Lines
Free custom number lines at exact scale — set the range, interval and tick marks.
A number line is a fundamental maths tool for counting, addition and subtraction, negative numbers, fractions and rounding. Set the start and end values, the interval between labels and the minor tick spacing to match exactly what you're teaching.
Print a long line across the page (or tile several) for classroom walls, desks or worksheets.
Printing at exact scale
Every sheet is drawn in real millimetres and prints at exact physical scale. For accurate output, set Scale = 100% (Actual size) and Margins = None in your browser's print dialog. Not sure your printer is honest? Run the printer ruler test first to confirm 50 mm really measures 50 mm.
Frequently asked questions
Can I show negative numbers?
Yes — set the start value below zero to include negatives.
Fractions or decimals?
Set the interval and tick spacing to mark halves, quarters, tenths or any step you need.
Is it really free?
Yes. Every template on printsheet.io is completely free, with no sign-up, no account and no watermark. Generate as many sheets as you like.
How do I get an exact-scale print?
Choose your paper size, then in the print dialog set Scale to 100% or “Actual size” and Margins to None. The sheet is defined in real millimetres, so it prints at true size. Use the calibration ruler page to verify.
Which paper sizes are supported?
A4, A5, A3, A6, US Letter, Legal and Tabloid, in portrait or landscape. Pick the size that matches the paper loaded in your printer.
Can I save it as a PDF instead of printing?
Yes — choose “Save as PDF” as the printer in your browser's print dialog. The PDF keeps the exact millimetre dimensions.
