What Chord Length Calculator does
The Chord Length Calculator on Omni Calculator determines the length of a chord inside a circle using either the chord height or the central angle, alongside the circle's radius. Users receive the chord length as the primary output, with the tool also providing the circle's diameter and area as supplementary results. The page introduces the definition of a chord and the underlying formula, then walks through the calculator's use and compares chord length to arc length. It is designed to be a quick, educational resource for anyone working with circle geometry. The Omni Calculator version distinguishes itself through its clean, step-by-step interface and the inclusion of related circle parameters like diameter and area alongside the chord calculation. It explicitly labels inputs for central angle, chord height, and apothem, and offers a shareable result link. Compared to other geometry tools, it balances mathematical explanation with practical usability, offering clear definitions and a straightforward layout without requiring advanced geometry knowledge.

Best for
Students, engineers, and hobbyists who need to calculate a chord length quickly without manual trigonometry, especially when they already know the radius and either the central angle or the chord height.
Limitations
- Results depend on the accuracy of the user-provided radius and angle or height inputs
- No unit conversion or switching within the calculator
- Primarily focused on chord length; other circle properties are secondary outputs
Chord Length Calculator FAQ
- Can I calculate the chord length if I only know the circle's diameter?
- Yes. The calculator accepts the radius as input, so you can divide the diameter by two to get the radius, or input the diameter directly if the interface allows it, and then provide the central angle or chord height to find the chord length.
- What is the difference between chord length and arc length?
- Chord length is the straight-line distance between two points on a circle's circumference, while arc length is the curved distance along the circle's edge between those same two points. The calculator explains this distinction and provides both values when possible.
- Does the tool work for segments of a circle, or only full chords?
- It calculates the length of a chord connecting two points on the circumference. For circle segments (the region bounded by a chord and an arc), additional calculations for area or perimeter would be needed, but the chord length itself is still determined by the same inputs.
- Can I use the calculator to find the radius if I know the chord length and height?
- The calculator is designed to find chord length from radius and angle or height. If you have chord length and height, you would need to rearrange the formula or use a different solver, as this tool does not solve for radius directly.
