How to choose a Good Protractor 

If you are going to buy your child a protractor, make sure he can wear it easily. There are many factors that make a protractor easy to use, such as precise scales, easy-to-read numbers, and the type of bow itself.

Ranging from hundreds, thousands, to tens of thousands, protractors have different characteristics. The thickness of each bow is also different which affects its use and storage. So, understand the protractor based on its ease of use. Here are some considerations for you to make when choosing a protractor.

1. Choose one that has large and clear numbers

Put functionality first when you buy a protractor. Therefore, choose a product that has a large measurement number. Besides being large, make sure that the numbers are easy to read without having to focus. That way, your child’s eyes will not be burdened when making observations while seeing the right angle according to the scale shown.

Usually, to make it easier for users to see the number of angles, manufacturers provide different designs on a series of measurement numbers. For example, adding a contrasting background color, such as black for a background with white numbers. A design like this will make it very easy to know the measurement results.

2. It is better to choose a transparent field color

Measuring tools which in this case is a protractor began to be produced with attractive designs. You may find bows in a variety of colors or even characters, some with sketches. If you want to buy a bow for your child to wear at school, then avoid products that are designed in color. Why?

Colors on the arc plane may look attractive, but it takes away from its ease of use. Maybe your child actually has difficulty seeing numbers due to being blocked by a non-transparent base color. Meanwhile, for those of you who want to buy a bow with color accents, choose the color that is in the numbers, not on the arc as a whole.

3. Types with or without margins also need to be considered

Each school generally does not give a standard or preference to a protractor. Even so, not a few schools also make provisions for students to follow in the selection of this protractor. If your child is skilled enough, choose a bow product that has white margins so that it will be easier to match the size of the angle.

On the other hand, if your child is not skilled enough in using a bow, please choose a bow without margins which makes the field of vision wider and observations can be more precise. However, look again at the provisions provided by your child’s school so that your child can follow the lessons well.

Protractor is a measuring tool that is inexpensive and easy to use. However, the low price sometimes makes manufacturers subordinate the quality. This causes the measurement results are often not precise because the arc scale has shifted quite far. Therefore, we recommend that you choose products issued by trusted and experienced manufacturers.

Some names like Butterfly are certainly one of the most recommended. Besides being easy to use, the low price also makes it widely used. Also choose products made of plastic with a thickness of more than 0.5 mm. This way, your child can also use a bow to draw lines easily.
