How do I turn a square entryway between two interior rooms into an arched entryway? The entryway is about three feet wide. I don't want to narrow or widen it just arch it.

Here are plans

Here are the plans I plan on using in my kitchen next month. Screw two pieces of plywood together and cut them in the shape of an arch using a saber saw. I'm planning on making a template by folding a 3ft piece of paper in half and tracing a bent piece of 1/4 lattice to it. Cut on the trace line and the template should be full size and symmetrical when you unfold it. Install a two by three header on the ceiling. Mount one piece of plywood to header. Hold a two by three up to the header and against the entrance opening on one side and trace the bottom of the arch to it. Cut the trace line with a saber saw and then shorten the top side by 3/8's of an inch. Repeat on the other side. Attach both studs to the entrance wall and then mount the plywood to the studs. Install two more in the same method evenly spaced. Mount the second piece of plywood to the frame. Cut a strip of 3/8's plywood to 1/8" less the inside dimension of the plywood. Use a circular saw to make 3/16's deep cuts into the back side of the plywood so it will bend easily when attached to the bottom of the arch. Make more cuts closer together for a tighter arch. Wrap it with sheetrock, attach flexible corner bead, tape and mud... Before starting, Calculate the thickness of the plywood, studs and sheetrock to equal the current entrance way.......

Hello
If this opening is just sheetrock now and is 36" wide come down on eadh side 18" cut back the sheet rock up over and down the otherside back 1" to 2" so you do not have a build up of sheetrock mud...do this on both sides ......add sheet cut out the arch add 2x4 between the sheetrock in short peices 3" to 4" long....add flex corner molding and sheet rock mud....each step is important to make a smooth arch so check each stop before moving to the next....Good Luck....If you have a door frame you will need to remove it back to sheetrock and go from there....a round arch is 1/2 the width down on each side.....36"=18", 38 1/2'=19 1/4" and so on...........

Is there any reason why the arch must be constructed of plywood and then covered with sheetrock? Is it possible to make the arch with sheetrock only and eliminate the plywood?

Welcome to the forums Chase Hunter!

The plywood helps to give the arch a uniform shape. It also makes the arch edge stronger.
