KDE Screen Ruler is a very simple application, with only one aim in life. To measure pixel distances on your screen. It is useful for working on layout of dialogs, web pages etc.

To start KDE Screen Ruler, choose Applications → Utilities → More Applications → Screen Ruler from your application menu.

Clicking with the left mouse button on the KDE Screen Ruler will turn the cursor to a cross with four arrows and enables you to drag KDE Screen Ruler around the screen.

When you move the mouse over KDE Screen Ruler, your cursor will turn into a red arrow. As you move the cursor, KDE Screen Ruler will display how far from the origin the cursor currently is.

You can resize the ruler by moving the mouse over the handle on the left or right edges of KDE Screen Ruler (the top or bottom edges when it is oriented vertically), holding down the left mouse button and dragging the handle.

You can change the orientation in two different ways:
