Digital Angle Finder Ruler

It’s time for another Cool Tool review. I’m going to show you a digital angle ruler. It’s sorta like digital calipers but for angles. I got this one for $19 on Amazon and if you want the same one, using the link in the description helps to support my videos and the Cool Tools blog.

Angles are tricky things. A lot of tools have useful presets for marking and cutting things at 90 or 45 degree angles. But what if you’re trying to figure out the imperfect angle of something that already exists?

The angle ruler is essentially two 7-inch rulers hinged in the middle. A display shows you the angle in degrees. You get an on/off button and a button to zero out the measurement. An included Lithium coin cell slots in from the side.

It measures in either direction. You can flatten it out and zero it, and measure up from here.

You can compare angles by measuring one, zeroing out, measuring the other to see the difference.

If your tool’s built-in angle guide isn’t reliable, you can use this to verify it or calibrate it.

And for me one of the best features of this tool is that you can tighten this nut on the hinge to lock an angle in place. This way you can measure an angle, lock it in, and then transfer it right to whatever material you’re using to reproduce the angle.

Downsides of this tool? It’s cheaply made. I suspect it would only take a few drops to break the display or battery compartment. I also can’t vouch for the measurements being scientifically precise.

And the ruler is a little useless. The display covers a portion of it. The zeros match up at a 90-degree angle — so it can sorta double as a square, but it’s not my first choice as a ruler.

But for $19, it is my first choice for measuring angles, and for that it’s a bargain. You can pick one up using the link in the description. And remember, you can see thousands of reader recommended tools like this at Cool-Tools.org.
