The "measure" is the width of a body of type. This little tool helps you find it with a simple click in the toolbar and highlight of a line of text.
WHY WOULD I DO THAT?
The length of a line of type impacts how readable it is. Generally, a good measure is between 45–80 characters per line.
FOR DESIGNERS, FOR DEVELOPERS
Designing legible content requires a lot of attention, across the huge range of device types and screen sizes. A good measure on a desktop monitor might be 80 characters, but on smaller screens or multiple columns might be 45 characters. Although this could all go out the window depending on the colours or typeface used. So do remember to apply your own discretion, too!
Measure makes it easy to be more precise when creating for the web.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
