Plays Nicely With
Your Existing Tools

EpicRuler works inside any app you have, anywhere on your screen. It's not limited to the browser and could be configured to work seamlessly with your existing tools.


You can measure anything on your screen. Yep, literally anything! EpicRuler works inside any app, and you can measure the distance, dimension or position of any on-screen element, making it the ultimate measuring tool for macOS and Windows.


Measure padding, margin and whitespace between elements.


Measure the size of any object (width & height).


Measure the absolute or relative position of any element.


Use the snappable guidelines to align any elements on your screen. Once added, the guidelines stay on your screen until you remove them. This way you can use it during the design phase inside your design tool or during the implementation phase inside your browser or IDE.

Horizontal Guideline

Align on-screen elements horizontally, along the x-axis.

Vertical Guideline

Align on-screen elements vertically, along the y-axis.


EpicRuler comes with a color picker like no other. Besides picking colors from anywhere on your screen, you can also use the color picker to quickly check the contrast between the foreground and background of elements with the innovate click & drag contrast checker. As a nice addition, the color picker comes with a size adjustable loupe that is also useful for inspecting unintended layout shifts.

Pick colors

Check contrast
