Set printer scale to 100%
The rulers below are pre-set to commonly used scales. Print this page and compare the 1:1 scale against a standard tape or ruler.
Un-check 'Top Border' to remove ruler top line. Un-check 'Color' to print in black and white.
For an on-screen image, measure the known dimension of an object in the image (eg: a wheel diameter)
Measure at Scale From On-screen Image
Use a full scale ruler to measure a known measurement from an image on-screen. In the Calculate Scale dialog, enter this measurement into Measured Length and the actual full scale measurement into Full Scale Length. Hit Calculate Scale to calculate the scale. This enters the scale into the lower Measure at Scale dialog. Now, measure any length from screen image or plan, enter into Measured Length and hit Calculate to calculate the actual full scale length.
If scaling from an on-screen image, you can enlarge the image on the screen for more accurate measurements.
Hold down the CTRL key and hit + to enlarge, - to decrease size and 0 to re-set to 100% (normal).
Strangely enough, because the paper scale rules are much thinner than conventional scale rules, it can be easier to take measurements from plans. Conventional scale rule edges are thicker than paper, so the calibrations sit above the plan surface. The paper scale rules sit flat, directly over measurements being scaled.
