A SOFTER WAY TO FRAME AN OPENING
A soft segmented arch, also called an eyebrow arch, adds a gentle curve to an otherwise square opening. Its simple shape softens the transition between rooms without the pronounced height of a half-circle arch.
There are two common ways to choose your rise. One is to use a fixed rise, such as 6", 8", or 12", across every opening regardless of width. Wider openings will have a flatter-looking curve, while narrower openings will have a more pronounced arch.
The more popular approach is to set the rise at 12% to 16% of each opening’s width. This keeps the proportions similar as the openings get wider or narrower. For example, a 15% rise gives a 60" opening a 9" rise.
