Both digital and non-digital, there are several tools to measure the angles that you have to know. This can be important to enrich your idea and ability to solve different problems during work sich each of them is used for different purposes. So, this page may help you decide which one is suitable for you.

We are trying to cover comprehensively all the tools used to measure the angles. These are the 5 options that successfully gather for you.

## 5 Types of Tools to Measure Angles

### 1. Protractors

The protractor allows you to measure an angle that is generated by two sides of an object. And therefore, you could do the measurement at any position you want as long as you get the angle.

This type of angle measuring tool can be digital and non-digital. The digital lets you quickly measure but requires battery power. You don’t need battery power when it comes to mechanical protractor but you couldn’t get the reading quickly. Make sure your vision is good when using the mechanical one.

There are several types of protractor commonly used:

**Half Disk Protractor**

As the name suggests, it looks a half-disk shaped. This model is generally used in school when measuring an angle generated by two intersecting lines.

We see this is not a nice pick for professional work. Though it measures angle, however, it doesn’t provide speed to the users. You have to carefully use it since the human error chance is high.

**Bevel Protractor**

This model comes with at least two arms and a hinge to give flexibility, speed, and accuracy in measuring an angle. By using this model, you could measure whether it is an external or an internal angle. Moreover, you could get a more accurate angle measurement with this model since the arms stick directly to the surface.

The digital model of this model is also available to choose from. As you have to stick the arms, you could get the angle reading easily. You don’t need to see the scale perpendicularly, you could read the screen at any position.

### 2. Angle Gauge

An angle gauge lets you measure the surface angle easily against the horizontal axis in which using a protractor can be impossible to do. Simply put the angle gauge on the surface you want to measure its angle, and then it will display the reading.

The model can be digital and mechanical. Both of them have different advantages and you could consider which one is more suitable for you.

### 3. Multiple Angle Measuring Ruler

Though this tool cannot exactly measure the angle, however, it’s very helpful to simplify your job in accordance with angle measurement. Instead of measuring each angle and measure the length of the sides one by one, a multi-angle measuring ruler functions to copy the multiple angles of an object easily. Moreover, it duplicates the dimension as well so you don’t need to measure the side length again.

This advantage is therefore included in this list.

When you have made a trapezium board, and you want to duplicate that board for several copies, you could easily do that with this tool.

### 4. Try Square

Similar to the multi-angle measuring ruler, a try square doesn’t show the reading of the degree of an angle. However, it’s designed such a go/no-go gauge. If an angle is not 90° shaped, then it can be detected by this tool.

The advantage given by the try square is the speed. You could easily determine an angle whether it’s a 90 angle or not.

Moreover, it can be a ruler. Instead of carrying the ruler, this tool provides two functions at the same time.

### 5. Sine Bar

A sine bar doesn’t show directly the reading of angle. Instead, you have to do some math of trigonometry. By the support of the gauge block as the height adjustment, a sine bar will shape a triangle. The accuracy of gauge block and sine bar is highly determinable to the accuracy of the angle measurement.

## Last Thought

That’s all for the tools to measure angles. In summary, you need to choose the right tool to measure the angle. If you have to measure the surface’s angle accurately, the angle gauge is suitable for that job. While protractor is used when you have to measure an angle generated by two sides that intersect. You could use a try square to make sure whether a certain angle is 90 degrees or not. On the other hand, using a multi-angle measuring ruler lets you duplicate several angles of a single object easily, allows you to work faster.
