This extension measures the dimensions from your mouse pointer up/down and left/right until it hits a border. So if you want to measure distances between elements on a website this is perfect. It doesn't really work with images because there the colors change a lot pixel to pixel.
Images & HTML ElementsMeasure between the following elements: images, input-fields, buttons, videos, gifs, text, icons. You can measure everything you see in the browser.
MockupsYour designer handed you mockups as PNGs or JPEGs? Just drop them into Chrome, activate Dimensions and start measuring.
Keyboard ShortcutYou can start and stop dimensions with the ALT + D shortcut.
Area BoundariesWanna get the radius of a circle? Is text standing in your way? Press Alt to measure the dimensions of a connected area.
