Order cheap protractors today

If you’re looking to buy a cheap protractor today, there are plenty of budget-friendly options to choose from. Whether you need a simple clear plastic protractor for schoolwork, a sturdy triangular model for drawing, or even a large protractor for the classroom whiteboard, you’ll find the right fit without breaking the bank.

What is a protractor

A protractor is a simple tool used to measure and draw angles. Protractors help people figure out how “open” or “wide” an angle is, kind of like a ruler for angles.

Most protractors are made of clear plastic and shaped either like a triangle, a half-circle or a full circle. To use one, you line up the straight edge with one side of the angle and read the number where the other side meets the curve.

The different uses of protractors

People often use protractors in school and college classes for mathematical subjects like geometry.

Protractors are also used by artists, designers and crafters for drawing, when they need to make sure an angle is just right.

To summarise, a protractor is handy in maths class, art, or even for real-life things like checking the angle of a door or maybe a pizza slice!

The different types of protractors

There are many different types of protractors, each with a special use:

Clear Protractor: A see-through plastic protractor, often semi-circular (180°), commonly used in school classrooms to measure angles up to 180°
Full-Circle Protractor (360°): A circular protractor that can measure all the way around a circle
Adjustable Protractor (Bevel Protractor): A protractor with a movable arm that can be set to different angles, used for carpentry, drafting, or engineering
Small Protractor: Compact and portable, great for student pencil cases or quick classroom use
Giant Protractor: An oversized version often used on classroom whiteboards or blackboards so teachers can demonstrate angle measurement clearly
Digital Protractor: An electronic tool that shows angles on a screen, useful in construction and design work.

No matter the size or style—clear, small, adjustable, or even giant—there’s a protractor to suit every need, from the classroom to the construction office.
