Printable ruler
A ruler is only useful if it is accurate, and most printable ones are not, because the print dialog quietly resizes them. This one is vector geometry in real millimetres, and every sheet carries a 50 mm bar you can measure to confirm the print came out right.
- Measuring when no ruler is to hand
- Checking a parcel or screen size
- School geometry
- Craft and sewing
Scales
Print at 100% scale, not “fit to page”. Every sheet carries a 50 mm bar — measure it to confirm the print is true to size.
