    Default Need radius of arch with given length.

    Registered forum members do not see this ad.

    I was given an arch length dimension and need to figure out the radius of the arch. I know the depth of the arch but not the width.

    Is there a formula for figuring out the radius of an arch with a determined depth?

    See attached pdf

    thanks in advance

    Here is a calculator that uses any two parameters.

    The Height is also known as the sagitta or versine of an arc.
