We all remember math class in grade school and being asked to calculate angles for a geometry chapter. Well, while you might not have realized it back then, measuring angles with protractors can be very useful in life. If you’re planning on building a new house to start a family in or you’re getting things ready to add an addition on to your home, mapping out precise measurements with a protractor is a good idea. If you’re an engineer, you know how valuable a tool this can be. So if you have a geometry final coming up or are realizing you should’ve paid attention in that geometry class when you were younger, here are some protractors that could be right for you.

Best Digital Protractor

Taking human error almost completely out of the equation, the GemRed 82305 Digital Protractor Angle Finder helps you pinpoint exactly the angle you need. It is made from stainless steel, so it’s built to last. It is a protractor and ruler combination, so measuring is made super simple. The edges might be sharp, so this is not meant to be used by children. The total length is 400mm and the digital readout is accurate within +/-0.3°. You just rotate the protractor to the desired angle and the digital display will show you what the angle is. You cannot measure reverse angles.
