From the classroom to the office, a sturdy and durable geometry compass can help solve equations, create beautiful designs and finish plans for building projects. Most commonly used in math classes, a geometry compass is a versatile tool that helps to create circles and arcs and create intricate pieces of art.
A geometry compass uses lead or a pencil to draw smooth circles and arcs in a variety of sizes. Sold on their own or in sets that include other commonly use math accessories, including protractors and rulers, a geometry compass is a tool that students typically begin using in elementary school and may continue using throughout high school and college. After graduation, careers in engineering, drafting and architecture may also require the use of a geometry compass.
For artists who want to create exact circles or intricate mandalas, a geometry compass presents a convenient way to make seamless arcs and circles. Geometry compasses can also be used for DIY projects, like painting murals or designs on walls and furniture.
If you’re in the market for a reliable geometry compass, check out our top picks below.
1. Mr. Pen Geometry Set
For young learners who are beginning to take on more complex math problems, the Mr. Pen Geometry Set comes with a comprehensive set of materials to help them explore exciting new topics. The 15-piece set comes with two metal compasses, including a study compass and a graphic compass. Extra lead for the graphic compass, as well as two short pencils and one mechanical pencil for the study compass, are also included, as is an eraser, sharpener, three rulers, two protractors and a divider.
Pros: The set is packaged in a reusable bag that helps to keep the contents together.
Cons: The compasses included in the set are not as durable as other options and are better suited for younger students.
2. Maped Study Geometry 10 Piece Set
For a more compact set that still includes the must-haves for geometry class, we recommend the Maped 10 Piece Set. Included in the set are a study and graphic compass, both made with durable metal that is resistant to bending or flexing. The compass heads have an ergonomic design that makes them comfortable to use. The compasses can draw up to a 10-inch diameter and the set includes the necessary ink refills, pencil and pencil sharpener required to use the compasses.

Backup screws and nuts are also included and ensure that customers can use the Offizeus for a long time. The compass also comes with ten pieces of lead. Like the Mr. Pen set, the Offizeus comes in a reusable clear carrying pouch.
Pros: A grooved knob provides a secure handle that helps prevent slips when drawing circles.
Cons: The lead can sometimes slide out of place.
4. Drafting Compass for Geometry Set
For a compass that can handle large projects, we recommend the Drafting Compass for Geometry Set. The set includes a small and large compass and an extender that can be used with the large compass to create circles that are 24 inches in diameter, much larger than the max 10-inch diameter of the other compasses on our list. The set also includes lead, a sharpener and a container for the lead. A stylus that can be used in the handle of the compass or separately is also included in the set, which comes in a reusable plastic case.
Pros: The set includes an e-book with details on using the compass and the extender, as well as tips on dealing with geometry problems.
Cons: The compass can become slightly unsteady when used at its maximum 24-inch diameter setting.
