It is VERY thin, about 1/4".  We bought it to go over carpet and I DO NOT RECOMMEND THIS UNDER ANY CIRCUMSTANCE.  If you are buying it to put on hardwood, i bet it works great.  Hard to find these colors elsewhere (and I searched!) but this just doesnt work.  Its so thin and all it does is buckle and bend and sounds crinkly under your feet.  Again - if it is on hardwood i bet this solves the issue...but - we tried EVERYTHING, including a sticky rug pad made for rug-to-carpet.  We even STEAMED it inch by inch with a commercial steamer....nothing made the wrinkles totally come out - the backing is just so plastic-ey and the thinness of the rug doesnt help it to weigh it down.  Beautiful colors, pattern isn't as cheap looking as some others...but - it doesnt work for ontop of carpet.
