Web developers often make use of installable rulers that reveal how tall or wide a design element is. But in case you find yourself using somebody else’s computer that does not give you installation privileges, “Online Drag-and-Drop Ruler” is an option worth checking out.

Online Drag-and-Drop Ruler is a free web based ruler service that helps you to determine how long or wide a certain web element is. On the service’s homepage you get a text bar along with some of the websites the ruler has recently measured. Enter your website in the text bar and click on the “Get” button.

This will open the site in a frame of yellow rulers that can aid in finding a site’s overall length and width. You get two additional pink rulers ““ one vertical and one horizontal. Their lengths are fixed: 400 pixels. You can measure a web element by placing these rulers against it and noting the ruler reading.

Apart from pixels, these moveable rulers can give reading in centimeters and inches as well. Unfortunately the rulers’ length cannot be adjusted as the user wishes but hopefully the site owners will recognize its importance and add this feature soon.

• A simple and free web ruler to measure design elements on websites.
• Provides two 400-pixel long rulers ““ one vertical and one horizontal.
• Works on any web browser.
