Most arches are true circular arches, or ones based on a circle with a radius.
Standard arches are either half-circle or less than half-circle arches. The above images show true, circular arches; one being a half-circle arch and the other a less than half-circle arch. Both can have the same radius but one is only a piece of the half-circle arch. This is why we ask for the Height (green) and the Width (blue),
not the radius.
Please Note:
If your arch is not a true circular arch with a radius, these would be considered specialty arches and would require you to provide a pattern.
Other Non-Standard Arch Types:
Inside Barrel Arch -
Inside Barrel Arches are typically used for an inside corner, horizontally on a wall that is curved inward; on an inside surface of an arched
opening (rather than the vertical face of the opening); or on a vaulted ceiling, each with the coating on the inside of the curve and edges.
Where the arch adheres to the (wall/ceiling) surface there is no coating.

Outside Barrel Arches are typically used on an outside corner, horizontally on a wall that is curved outward, or mounted onto other curved
surfaces, with the coating on the outside of the curve and edges. Where the arch adheres to the (wall/ceiling) surface there is no coating.
