What size rug should I get for this 19×13 ft living room layout?

Hi everyone,

I’m trying to figure out the right rug size for my living room. The room is roughly 19 ft long by 13 ft wide.

Current layout:

• Modular couch along the 19 ft wall with a chaise on the left side against the wall.
• 70" wide entertainment center/TV console centered across from the couch on the opposite wall.
• Rest of the room will have a cabinet and a small table.

I attached a small visual of the room I put together quickly.

I want the rug to sit nicely under the couch and ottoman… Should I go with a 12×9, 12×10, or something larger? Any recommendations on size and placement so it looks balanced and feels right in the space?

Thanks!
