debbie 2008 - my dining room is the about the same size (a tad smaller maybe) and I just bought an 8 x 11 rug. I don't notice a difference in the appearance of the size of the room.

There are pictures on the link below where I asked for opinions on the rug. Maybe it will help you get an idea of what an 8x10 would look like in a room that size.

Here is a link that might be useful: 8 x 11 rug

Thanks Happy. 8x11 would also work for me. I am a bargain rug hunter and Home Goods is the place for me. They have many in both sizes with new inventory, constantly. I love your rug and your floor. I will be putting the rug over carpet, unfortunately.
