It doesn't say the weight. I will tell you that the older cardstock use to be heavier then then newer product. Bazzill went through some factory changes I believe and then sold to American Crafts over a year ago. They got rid of a lot of colors which I heard it was because of the new factory they went to. Said all of that to say the cardstock is not as heavy as it use to be. My guess is most is around 80# but I couldn't find an answer on their site. Some of the newer ones might even be 65# as it is very thin to my standards. But it still works alright. Also I use their textured cardstock not the smooth cardstock (I have one pack because that color only came in smooth). I lovee their textured cardstock and would not switch to anything else. But now that American Crafts owns both I have tried a couple AC cardstocks which aren't bad. But I loved the old original Bazzill the best.
