Developer Tools

Only for Mac

Mac

A ruler which does the measuring for you. Measure manually or simply hot-click inside a picture or rectangular region, and the rulers are automatically placed for you. Like magic! Easily toggle between two ruler custom appearances, including colour and opacity, to suit your requirements. Ruler Magic's instant measuring works from within any program. No need to change applications. Just hold the modifier keys (eg. control-shift) and click, perhaps on a logo in document or an image on the web. It's much faster than measuring on-screen with a classic ruler, and much much faster than looking up image dimensions. Features • "Magic" operation works from within any program • Supports retina display measurement • Configurable colors and opacity (transparency) to your liking • Configurable modifier keys (the keys held to activate) • Show or hide ruler ticks, ruler values, ruler cursors, ruler shadows • Optionally float windows above other applications • Manual measurement also available • Inbuilt help • Updated for Monterey and Apple Silicon The Magic functionality requires camera access and screen recording to work. If you have a feature request or bug to report, please use the support link instead of leaving a comment. This way we can better communicate with you to resolve any issues. Thank you.
