This interactive generator produces a number line image based on your settings and requirements. Once created, the image can be downloaded in bitmap formats: GIF, JPG and PNG. There is also an experimental feature to download as a vector image in SVG format.
The generator has been designed to help produce educational material for maths or science students and is free to use.
You can get started from stratch using the configurations below or you can start from an example configuration (see our Examples page).
I hope you find the generator useful! If you spot any problems or have any requests for future versions, please let me know via my contact page. Please share with others!
