Helix vs. Spiral — What's the Difference?
By Tayyaba Rehman — Updated on June 12, 2024
A Helix is a three-dimensional curve twisting around an axis, like DNA, while a Spiral is a flat curve emanating from a central point, like a snail shell.

Key Differences
A Helix and a Spiral are both curves, but they exist in different spatial dimensions and have distinct geometric characteristics. The Helix is a three-dimensional curve, meaning it twists and turns around an axis. On the other hand, a Spiral is primarily a two-dimensional shape, which winds around a central point in a flat plane.
When thinking about real-world applications of a Helix, consider the structure of DNA. This double helix is a tangible representation of this form. A Spiral, in its real-world representation, can be seen in the pattern of a snail's shell or a rolled-up tape, emphasizing its flat and radiating nature.
The concept of a Helix often finds use in architecture and engineering, especially when there's a need for structures to have a twisting form around a central pillar, like spiral staircases. In contrast, a Spiral is more prevalent in design and artwork, where the aesthetics of a radiating curve are desired.
While a Helix inherently has depth due to its three-dimensional nature, a Spiral can be given depth or be represented in three dimensions, but it originates as a two-dimensional concept. For instance, spiral galaxies, though expansive and three-dimensional, get their name from the flat, winding pattern they depict.
Both the Helix and the Spiral have mathematical definitions and principles guiding their formations. However, while the Helix is defined by its rotation and upward movement around an axis, the Spiral is characterized by its consistent, often logarithmic, spacing as it winds outward.
