SnapRuler is the first on-screen measuring tool which gets the job done. Three clicks -- and boom -- the dimensions you want are in your clipboard. That quick. Need to measure size of anything - on PDFs, PNGs, JPGs -- as long as you can see it -- it'll get it done. We don't show you life-like rulers on the screen -- that's old, we're new. To deliver the best experience ever -- we started from scratch. You want to get your objects measured -- not to measure them.

SnapRuler is the most accurate, pixel-perfect ruler ever made -- with SnapRuler you know exactly where your measurements start and end. Press the ⇧ key -- SnapRuler will instantly snap to the nearest edges and corners. Using highly tuned algorithms, SnapRuler knows where they are (some rounded ones too!). Missed it? Don't worry -- you can always fine tune your last action using arrow keys. Or undo it -- with secondary mouse button. That easy!

We worked hard to make sure your measurements are as quick as they can get. Our Loupe magnifies the screen around the pointer to make sure you get your measurement just right and it won't obstruct anything you might want to see. SnapRuler floats above your windows, ready to instantly measure anything on your screen. Press ⎋ or ⌘⇥ -- it goes away, press ⇧⌘U, or click the Dock icon - it's back, ready to do the task at hand. That easy!
