Weight has nothing at all to do with the thickness, or perceived thickness, of the paper. It is the actual weight of 1000 sheets of the designated paper in the uncut size it is produced in, which varies somewhat. But it's usually around 22x28 inches for cardstock types.
The thickness or stiffness of the paper has more to do with the type of fibers used and how much compression is used when rolling the paper. Often they will give you a "name" for the paper...like cover, or index, or something similar. 110 pound index is thinner than 110 pound cover, for example. I use a 110 pound linen text weight paper occasionally...it's thin like copy paper! And 110 pound GP index is WAY thinner than 110 pound Neenah classic crest cover.
So, weight is of less use than the designation "cover" or "index".

in awe of the One who gave it all.
I'll stand, my soul, Lord, to You surrendered,
all I am is Yours.
