The Best Digital Protractors

The Best Digital Protractors

A digital protractor is a tool that is essential for all levels of carpentry. It can help measure angles more accurately than other methods. This tool is also known as an angle finder or angle gauge. It is beneficial for both professional and hobbyist wood artisans.

The ones we used in geometry class are not the same as the digital ones. A geometry protractor is a tool used to measure angles on paper. But carpentry digital protractors can measure angles on three-dimensional objects. It means they can go inside or outside of the particular angle. But they are more like a gauge than a measurement device because they don’t have a way to tell you the angle.

These digital protractors or angle finders are similar to simpler models. They have a digital display that measures and displays the leg angles. It makes it easier to measure the angle of the protractor and takes less time. For general woodworking, cabinet making, furniture making, and carpentry, digital protractors can measure angles much more accurately.

There are many different types of digital protractors. The longer ones are easier to use and measure accurately. But the shorter ones might be better for some kinds of work, like furniture making.

A digital protractor is more accurate than a regular protractor. It is because it has a greater level of precision. However, even though most digital protractors are the same, it’s essential to consider the price. A cheap unit might not be as accurate as a more expensive one because its legs might not be made of metal but plastic. It could lead to wrong results in the long run.

We have reviewed seven digital protractors in this article. We’ve also written a guide for buyers to help you learn more about these tools. After reading the manual, you can choose the best digital protractor for your needs.

How to use a digital protractor?

Two types of measurement modes are available on a digital protractor:

  1. Horizontal measurement mode
  2. Relative measurement mode
  3. Horizontal measurement mode

The Horizontal measurement Mode measures the angle from horizontal surfaces accurately. It is done in two steps.

  1. First, ensure that you are in horizontal measuring mode.
  2. Second, place the digital protractor on the angle. The digital display shows an angle. The angle begins on the “horizontal plane.”
  3. Relative measurement mode

‘Relative measurement mode’ lets you use any surface to measure things. You do this by using three steps.

  1. Position the digital angle finder at the angle to be measured.
  2. Reset the angle to 0 degrees by pressing the zero button.
  3. Place the digital protractor on the angle to be measured in the third step. Displays the angle between “Step 1,” the first angle, and the second angle.
