The Calipers have several buttons which may appear differently on different skins. The arrow buttons on the slider will allow you to move and rotate the Calipers to measure any distance. The Diagonally downward pointing arrow hides the Calipers in the System Tray.

Configure Custom Units
The Calipers can be configured to measure in Pixels, Inches, Centimeters, Points, Picas and Twips.

By clicking the 'Calibrate Units' menu item you can easily define any number of additional units of measurement. You can also change the number of decimal places that a unit is measured in.

Windows Caliper Calibration Screen

The Caliper's measurements are based on pixels. When the units are changed to inches or centimeters the Calipers use a standard conversion factor to determine the measurement. If you measure something with the Calipers to be an inch, then a printout on a standard printer of that picture will also be an inch. The Calipers do not take into account the size as it is displayed on your monitor, so different resolutions will still measure one inch.

The Calipers use conversion factors to determine the built in units. You can adapt these units and enter your own custom units.

The easiest way to configure the Calipers is extend the calipers so that you measure exactly ten of your new measurements. Then open the "Configure Units" screen and enter the current number of pixels measured by the Calipers in the 'Number of Pixels' column. In the 'Length in Units' column enter '10' and the Calipers will be calibrated.

There is an animated example of how to Calibrate the Calipers in our getting started guide.

Frequently Asked Questions
Q: When I select the Inches unit the Calipers don't exactly measure an inch on my screen, can I change that?

A: The Calipers measure an inch as it would be printed on a standard printer. There's no way for the Calipers to automatically know how big an inch would be on your monitor, but you can configure a custom unit to measure an inch as it is on your monitor. To do so follow these instructions:

Set the Caliper to measure pixels.
Move the Caliper so that it measures exactly ten of your new units, in this case inches.
Note the pixel readout.
Open the "Calibrate Units" screen.
Click 'Add' to create a new unit.
In the "Number of Pixels" box type the number of pixels that you noted earlier.
In the "Length in Units" box type "10".
Click "Ok".


Q: I am using the Calipers to measure a map or scale drawing, how do I define a custom unit to show the correct number?

A: If you have a map, architectural drawing, blueprint or any image that you would like to measure to scale then the Caliper's custom units can be configured to show this. To do so follow these instructions:

Set the Caliper to measure pixels.
Move the Caliper so that it measures a known distance on your diagram, for example you might have a map, so set the Caliper to measure 100 miles.
Note the pixel readout.
Open the "Calibrate Units" screen.
Click 'Add' to create a new unit.
In the "Number of Pixels" box type the number of pixels that you noted earlier.
In the "Length in Units" box type "100", as we are measuring 100 miles on our diagram.
Click "Ok".


Q: Can I easily double the gap that the Calipers measure?

A: Yes. To double the gap just type "*2" and then press the "Enter" key. You may halve the gap by typing "/2" and then pressing "Enter". By typing "-50" or "+50" you can add or subtract distance from the gap measured. The Calipers can easily be used as a simple visual calculator like this.
