I ordered the 9 x 12 and the 9 feet was about 2.5” more. 12’ was spot on. So we just trimmed it down to fit the rug from Wayfair also. The padding is perfect as it lifted the rug and was more comfortable to walk on. Also brought the fabric of the carpet to life! Love it!  I also have the matching runner 2 x 6 and again it’s just a smidge bigger than 2 deer. So I will trim that as well. The passing is really good and strong rubber backing and the felt top make it a little bit of a challenge to cut so make sure your scissors are good. astrong. andstrongstrong!
