How to arch a doorway 
Determine the overall desired visual effect. 
If your home has more than 1 visible doorway, you should consider the effect if only 1 is arched. For a more uniformed pattern, think about converting all of the doorways into arches.

Possible answers: (i). If your home's interior has exterior arches, you may want to consider using them as a focal point. The arches affect the overall look of the home, but you don't need to replace them if that's necessary.. (ii). Decide the type of arch you want to construct. Organize the materials you'll need.. (iii). Arch doorways should usually encompass 1/2-3 feet in width. A staggered entryway can be defined by a vertical rectangle and three " horizontal " poles and three " vertical poles " placed at the side of the doorway.. (iv). If your home already has one visible doorway, add curves that originate from the outside. If your home is constructed within a more trapezoid pattern, add a curve that should be angled inward to create a sprinter-like look..
The answer is:
(ii).
