The Screen Calipers were created for web designers and other professionals to quickly measure on-screen distances.

Frustrated with your Screen Ruler? Then try Screen Calipers.

Drag Screen Calipers easily around the screen, measure distance inside and outside an object, nudge and flip it around by using the keyboard keys.

The readout gives the absolute distance in pixels.

As well as being able to change Screen Calipers' color scheme, you can also alter the look completely by selecting different skins.

Screen Calipers are totally cost free unless you'd like to have some additional advanced features that are only available to registered users. The price for the full version of Screen Calipers is a modest $15.00 US.

The Screen Calipers have a unique advantage over other on screen rulers due to their unique shape. Pixel-perfect accuracy is ensured every time simply by aligning the Screen Caliper's pointers around an object.

The Calipers can be used with any program as they float over other applications allowing quick and easy measurements.

To Use the Calipers drag them over the portion of a window you want to measure with the mouse. To extend the calipers drag the right hand side out using the mouse. The number in the text box will show the space being measured.

The Calipers have several buttons which may appear differently on different skins. The standard controls are as follows:

x   Close Window
<   Nudge Left
>   Nudge Right
c   Cycle Color
^   Flip Vertical to Horizontal

All the controls can be accessed through the keyboard:

Alt+Q Alt+X                 Quit
Arrow Keys                  Move Calipers
Shift + Arrow Keys          Extend Calipers
Ctrl + Arrow Keys           Move Calipers by 10

Alt+F                       Flip Vert to Horiz
Alt+N                       New Set of Calipers
F1                          Show Help
Ctrl+C                      Copy Value to Memory

By typing a number and pressing 'Enter' the Calipers will extend to that distance. Simple calculations may be performed by typing -, +, *, or / and then a number, then 'Enter'; the Calipers will extend to the new relative position.

When Closed the Calipers sits in the System Tray in the bottom right of the screen, you should see the Calipers icon next to your clock.
