To overcome this use the Calibrate Button in the upper left. Have a real ruler on hand for a one-time setup.

Your settings will be saved from each use so you don't have to redo the calibration each time.

If the ruler dimensions on the display are not matching up to a real ruler do the following:

1) Hold a ruler up to the scale and note if the image is larger or smaller than the ruler.

2) Press Calibrate

3) Pinch the image larger or smaller as needed.

4) Press Save
