Measuring an arc accurately is a fundamental skill in fields ranging from architecture and engineering to carpentry and art. This technique uses the principle that points on an arc are equidistant from the center.

Maintaining this data ensures that your measurement remains reliable for future applications or comparisons. Measure the arc two or three times using the same method to ensure consistency.
Prepare the following items before beginning: Flexible tape measure or ruler String or thin wire Pen or marker Calculator Straight edge or level (optional) Method 1: Direct Chord and Height Measurement This method is ideal for arcs where you can access the endpoints and the highest point. Calculating the Radius With the chord length (C) and the sagitta (S) recorded, apply the formula: Radius = (S/2) + (C² / 8S).

Method 2: String and Radius Technique For larger arcs or those where the center point is inaccessible, extending the curve to find the center is necessary. This equation derives the full circle's radius, allowing you to subsequently calculate the arc length if the angle is known.
