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.

Best Digital Protractor Buying Guide
When looking for a digital protractor, it is important to consider what you need it for. A digital protractor will help you to get precise angles for your home improvement projects. The digital protractor’s angle finder will lock in the angle you want, making it easier and more reliable to get the right angle.
The digital angle finder is the best product for getting precise angles and readings. It is very functional and can be used for many different purposes. There are many other angle finders on the market. Still, you can compare and contrast the protractors to find the key features you’re looking for.
Better Display Screen
A digital angle finder’s display is critical. The protractor’s display must be legible. You’ll save time when you go shopping because of it. Ensure the angle finder’s LCD screen is prominent and visible. If you need to work at night, you can choose a model with a backlit LCD screen.
When looking for a protractor, ensure it can measure the correct angle. You don’t want to buy a protractor that can’t do its job correctly. Get a protractor that can measure accurately.
You don’t want to compromise on your project’s quality. That’s why buying a digital tracer that will last a long time is essential. It will last for many years and be protected from accidental falls.
Digital protractors come in a wide range of styles. Some have only one purpose, while others have more than one. Users will find it easy to use the best model. The best model will be easy for users to use.
Long Battery life
If you need to use an angle finder for a long time, it is important to have one with long battery life. These models will turn off automatically after a period, which will help you save battery.
The Range of Angles
When picking a protractor, you should consider how far it can measure. There are digital protractors that can measure 180 degrees or 360 degrees. It may look like the 360-degree protractor is bigger and stronger, but this is not always the case.
For example, you need to measure a set of angles, but you know the maximum angle is 180 degrees. A 360-degree protractor might not be helpful in this situation because it can go beyond 180 degrees. You can measure below 180 degrees with a 180-degree protractor, but it might not be as easy with a 360 digital protractor.
Whatever type of digital protractor you purchase, it is essential to stick to your budget. Digital protractors can be expensive, but there are many affordable options available. You can find this equipment in different sizes, starting at $10 and going up to $200. Choose the angle finder that fits your budget.
A digital level/protractor should have a lot of memory to store angles. It keeps the buyer from having to measure angles over and over. Angles frequently used can be stored in the device’s memory, making it easier for the buyer to measure them accurately.
Check to see if your angle finder has a level built-in. This helpful feature will keep you from having to switch between your level and the finder every time you cut. If you lose your level, this feature can come in very handy. Another significant part of digital angle finders is that some can do more than one job. You won’t need as many tools on the job site.
With better features, digital angle finders can help you figure out how much your investment is worth. Each piece of wood you cut will fit perfectly with a cut calculator. It is done by the calculator automatically, so you don’t have to worry about mistakes. You can only get this cool feature on a high-end digital protractor.
How to use a digital protractor?
Two types of measurement modes are available on a digital protractor:
- Horizontal measurement mode
- Relative measurement mode
- Horizontal measurement mode
The Horizontal measurement Mode measures the angle from horizontal surfaces accurately. It is done in two steps.
- First, ensure that you are in horizontal measuring mode.
- Second, place the digital protractor on the angle. The digital display shows an angle. The angle begins on the “horizontal plane.”
- Relative measurement mode
‘Relative measurement mode’ lets you use any surface to measure things. You do this by using three steps.
- Position the digital angle finder at the angle to be measured.
- Reset the angle to 0 degrees by pressing the zero button.
- 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.
