The Best Digital Protractor Worthy of Your Toolbox

Best Digital Protractor Featured

The best digital protractor is essential for all levels of carpentry, from professional to hobbyist wood craftsmen. A protractor or angle finder is also known by the names angle gauge and miter protractor. Although you can measure the angles with scale and compass, you won’t get the accuracy a digital protractor provides.

Digital protractors are not the same as those you used in geometry class. A geometry protractor measures an angle on a piece of paper. The protractors utilized in carpentry work can be used to measure angles, but these angles are only applicable to three-dimensional objects. This limits the protractor’s ability to fit within or outside of the angle. These tools do not provide an integrated method of determining the angle. In that sense, they are more of a gauge than a measurement device.

These convenient digital protractors or digital angle finders are similar to simpler models. Still, they have a digital readout that measures and displays angles formed by the legs. This reduces the time and accuracy required to measure the angle of the protractor. Digital protractors can measure angles much more accurately for general woodworking, cabinetmaking, furniture manufacturing, and carpentry.

There are many lengths of digital protractors. It is generally easier to measure accurately with a longer model. The space they can fit into may limit the length of long protractors. A shorter protractor leg might be more advantageous for certain types of work, such as furniture making.

A digital protractor’s greater accuracy is another important consideration. Although most units will be the same, units at lower prices might not be as accurate. Low-cost units may have plastic legs rather than metal legs. This could lead to inaccurate results over time.

In this article, we have reviewed the seven digital protractors for your convenience. Also, we have produced a comprehensive buyer’s guide for all the new shoppers. You will definitely have a better understanding of these protractors after you have finished reading the buyer’s guide. You will be able to select the best tool suitable for your needs.

Best Digital Protractor Buying Guide

There are many factors to contemplate when searching for a digital protractor. Unlike its manual counterpart, the digital protractor will allow you to use a digital screen to assist you. The angle finder will automatically lock you into the desired angle. This allows for a very consistent and precise angle. This is crucial for home improvement projects that require an angle finder. It makes sense to invest in the right tools to help you improve your home.

The digital angle finder is the most functional product available for getting precise angles and readings. There are many angle finders on the market. You can compare and contrast the protractors to find the key features you are looking for.


Better Display Screen

A digital angle finder’s display is crucial. You should be able to easily read the display on the protractor that you’re going to shop. Clear visibility on large LCD screens makes it easier to see and makes life easier. Angle finders with backlit LCD screens are available for those who work at night. Always choose a model that has an ample display to make it easy to read.


High Accuracy

You should ensure that the protractor you shop for can accurately measure the job. You shouldn’t purchase a unit that is incapable of performing this task. Make sure you get the right angle measuring unit.



Nobody likes to compromise on the quality of their projects. It is therefore important to invest in a durable digital tracer. It will last many years and be protected from accidental falls.

There are many models of digital protractors. Some have one function, while others have several. This should not be confused as the best model will make it easy for users.


Long Battery life

A digital angle finder that has a long battery life is essential if you work for a long time. These models have auto shut down features that allow you to turn off the angle finder when not in use and save more battery.


The Range of Angles

When choosing a protractor, it is important to consider the measuring range. Digital protractors measure 180 degrees or 360 degrees. 180 degrees is a straight line for those who are not familiar, while 360 degrees is circular. The 360-degrees protractor may seem larger and more powerful, but this is not always true.

For instance, let’s say you need to measure a set of angles but know the maximum angle is 180 degrees. A 360-degree protractor may not be useful in this situation. It can even go beyond 180 degrees, so you might get an incorrect measurement. You can measure below 180 degrees with 180-degree protractors, but not as easily with a 360 digital protractor.



It doesn’t matter what type of digital protractor you purchase; it is crucial to stick within your budget at all costs. Digital protractors are no different. You should make wise investments in them. You can find this equipment in many sizes, starting at US$ 10 up to US$ 200. Choose the angle finder that suits your budget.


Bigger Memory

A good digital level/protractor should have a lot of memory for storing angles. This allows the buyer not to have to re-measure angles repeatedly. Angles that are frequently used.


Level Included

It is important to check if your angle finder includes a level. This handy feature will help you avoid having to switch between your level and the finder every time you make a cut. This is also an insurance policy for if you lose your level. It’s an excellent feature and is included in many digital angle finders. These are the things that can make a big difference in your job. A digital angle finder that does more than one job is one less thing you’ll need.


Cut Calculator

Digital angle finders with better features can help you appreciate your investment. The cut calculator is one of these features. This calculator will ensure that each piece of wood you cut fits as you intend. There’s nothing worse than cutting a piece only to discover that it was half an inch off. This is all done automatically by the cut calculator, so your piece will fit perfectly every time. This exciting feature is only available with a high-end digital protractor.


How to use a digital protractor?

There are two types of measurement mode in a digital protractor:

  1. Horizontal measurement mode
  2. Relative measurement mode


1. Horizontal measurement mode

The “Horizontal measurement Mode” measures the accurate angle from horizontal surfaces. This is a two-step process.

Step 1: Make sure you’re in ‘horizontal measuring mode’.

Step 2: Place the digital protractor onto the angled surface. This will show you the angle displayed on the digital display. The ‘horizontal plane’, or level surface, is used as the base for the angle.


2. Relative measurement mode

‘Relative measurement mode’ allows users to use any surface of whatever angle as the measurement point. This is a three-step process.

Step 1: Place the digital angle finder on the angle that you want to measure.

Step 2: Reset angle to zero degrees using the ‘zero button’.

Step 3: Place the digital protractor onto the angle you want to measure. The angle between “Step 1”, the first angle, and the second angle will be displayed.



Our comprehensive overview will give you a necessary understanding of the various tools available and their capabilities. This knowledge should help you make an informed decision about your digital protractor. However, ensure that the protractor and angle finder you purchase have all the features you need to tackle the challenges of home renovation.

Can you use your phone as a protractor?

Ans: AR (augmented realities) protractor apps are now available online. These apps can provide an estimate for any angle it can recognize. But, it is totally clear that these apps cannot be trusted as they do not provide an accurate measurement to be used in woodworking or construction projects as much as a digital angle finder.

How accurate are digital protractors?

Ans: Digital protractors or digital angle finders, or digital angle gauges measure angles with 100% accuracy, unlike manual protractors, whose accuracy depends on the users’ expertise. The arms are laser etched, which contributes to extra accuracy.

What is relative angle measurement?

Ans: Relative angle measurements are the difference between two surfaces measured in degrees, percentage of incline, or another unit.

What is the suitable digital protractor for you?

Ans: There are two types of digital protractors: (1) the block protractor and (2) the protractor with handles. The former’s main function is that it measures relative angles and can be used for a level. On the other hand, the protractor with handles measures angles and lengths. You should choose the one that best suits your needs. This versatile tool will help you in many ways.

What is the zero function in digital protractors?

Ans: Zeroing is creating a reference point or a start point for your digital protractor. It is useful when measuring angles that are relative.
