Top 10 Best Geometry Compass: Reviews & Buying Guide

My friend recently held a workshop on geometric art. He was frustrated to see that so many of the participants couldn’t get perfect circles.

Frustrating, isn’t it?

Drawing a circle shouldn’t be a big deal. But, if you’ve landed up with a drawing compass that’s loose hinged, you’ll have a lop-sided circle.

Whether you’re a high school student or a student of engineering, architecture or geometric art, without the right tools like scales, protractors, set squares, and a good drawing compass, you’ll be at a loss to do a good job on the drafting paper.

More often than not, we go to the stationery and pick up any geometric set, hardly sparing any thoughts to the end results.

Although straight lines can be more or less tackled with a ruler, circles need a bit more tact as they’re not at all linear. Here’s where a good geometry compass can cut the deal.

The market is flooded with various brands of compasses. It’s an essential tool for both students and professionals.

In this article, we have compiled a list of the best geometry compass models that have glowing reviews from their users. Hope you find this article informative and useful.

Things To Consider Before Buying A Geometry Compass

Purpose

First things first. Before you think about buying a math compass, you need to consider what kind of work you’ll use it for.

A simple, easy to use basic compass is good for young students who have just been introduced to geometry. However, if you’re a professional or a crafts person, then you might need something that can make bigger circles and strong arcs.

For students’ use, you need to consider how durable the drafting compass is, given the fact that the user will probably not be very careful either using or storing it. So, you might consider a stainless steel or a metal one over a plastic one.

Grip

How much control you need to have over your drafts and drawings is another factor to consider. If you’re teaching young students, then drawing basic circles is the only concern you have.

On the other hands, if you’re dreaming up a mighty project where the circles must be accurately drawn, you need to have a compass that provides a better grip. In this case, look for one that has the tip ergonomically designed for easy hold and control.

Versatility

Another very important point to think about is the degree of versatility you’re looking for in the best compass geometry.

An extension can give you the versatility as it can be easily placed instead of the regular leg, thus extending the reach. With an extension, you can draw really large circles, if that’s what your project demands.

Whether you can use only a pencil or a host of other writing instruments in your compass also determines its versatility. For artists and designers, it’s important that the holder is capable of accommodating marker, colored pencils, crayons and others.

Accuracy

Look for sharp, metal tips if you want to draw or mark strong and accurate circles. The sharpness of the tip is going to determine how well-defined the marks are. Another advantage of sharp tips is that they don’t move away in different directions on paper.

Another factor that contributes to accuracy is the center point of the compass. If there’s a wheel in the center that you can adjust by tightening it, you’ll have no problem drawing perfect circles. So, a locking system is good for precision.

Some compasses come with push button or sliding feature on the legs to help you adjust the size of the arcs quickly. These will also impact the accuracy with which you can draw circles.

Accessories

As the compass has sharp tips, make sure you buy a brand that gives you a hard case or a reusable pouch for carrying around safely and easily.

Other accessories like extra pencil leads, screws and nuts, sharpeners, erasers, and others should be included in the kit to prevent your work from getting hampered.
