So the 9x9 was 8'7" by 8'7" and is also not quite square. Had I known this I could have bough the 8x8 rug pad and saved time and headache of trimming. Overall it looks quite nice and feels nice on the feed. I would recommend a thick rug pad if this is for the living room. I got the Contour Lock from Wayfair, and it works well.
