How you position the rug has a lot to do with how you plan to place your furnishings. They go hand in hand. You have provided enough info about the details of the room for us to make a good suggestion, so here are some random layouts with corner fireplaces.

Base it on the size and placement of the furniture and measuring out two sizes may help you decide which look you prefer.

If you are ordering a rug, get the smallest size available as a sample, then return it when you order the full size one.

Round is always an option. And you can have something custom bound from broadloom from your local mom and pop floor shop.

Everyone!!

Thanks everyone!

I often ignore corner FPs and just arrang the furniture to fit how I like it then yiu choose the rug to work with thta arrangement
