How to make the printable ruler
- Download the printable ruler PDF or image file.
- Set your printer’s page size to letter or A4 depending on the ruler template you downloaded.
- Set page scaling to “none”. The printer setup is important to ensure that your paper ruler is accurate.
- Print on standard paper for one-time use or on card stock if you want your ruler to last longer.
- You can laminate printable paper rulers if you want them to last for a long time or if you want to write on them with wipe-off markers.
- When you have printed your ruler, take a store-bought ruler or a tape measure to check the accuracy. If it isn’t accurate then you need to change your printer’s settings.
