  - (Optional) If you already have the correct scale ratio, directly define the measurement value and choose the appropriate unit in the Scale Ratio group.
  - Then in the pop-up Calibration dialog box, click Store Scale in Page to apply the new scale ratio to the current page, or click Apply to All Pages to apply it to all pages (Or click the / icon in the Scale Ratio group to apply the new scale ratio to the current page or all pages).

- With the Use Scale and Units From Document (When present) option unselected, directly define a custom scale ratio in the Format panel, or click Calibrate in the Scale Ratio group to define a new scale ratio. The defined scale ratio will only be applied to the current page.
Foxit PDF Reader will display the measurement results, measurement markups, and rulers by default. To hide these information, please uncheck the relevant option(s) under the Setting group.
