  • (2018-05-23) Amit: This ruler fulfilled my requirements. It helped me to measure the page elements but those bubbles showing the dimenssions are a bit distracting and not good. But overall worked really good :)

  • (2018-04-18) Boris Polak: Can't use it on responsive view because these ugly bubbles with text gonna cover big part of screen and you cant turn them off
  • (2018-03-16) David Jaw Hpan: Love it
  • (2018-02-12) Niels van Amstel: This Ruler rules over Page Ruler! 5 stars!
  • (2018-01-29) Russell Reid: Great so far, better than page ruler.
  • (2018-01-16) Darin Hensley: As a developer, this tool is a life saver. My old tool for chrome 'Page Ruler', no longer works and is no longer being maintained. As it turns out, I like this one even more!
  • (2018-01-05) aishwarya aggarwal: Useful tool
  • (2017-09-16) Дмитрий Гонтарь: Пока самая адекватная линейка из тех, что пробовал (пробовал все которые отображаются по ключевому слову ruler)
  • (2017-09-13) Antony Gray: It does the job simply
  • (2017-04-27) Сергей Храпин: Программка вроде ничего, но... Она, видимо, построена на label+input. У меня есть два сайта, на которых есть формы, которые довольно оригинально оформлены. Так вот, когда я открываю эту программу на моих сайтах, то весь текст из "полей" (width, height и т.д.) этой программы исчезает (уплывает, растворяется) согласно тому, как это прописано на МОИХ сайтах. Не знаю как это происходит, чудеса...
  • (2017-02-10) Laurence Lord: Intuative keyboard shortcuts would be a good addition to this.
  • (2017-01-24) Арсений Березин: good ruler!
  • (2016-12-22) Warmuser: Works really good! Very easy to use!!
