Have you ever wondered just what ’65lb’ card stock really means?  I do!  So I scoured the net for information that would help give me a better understanding of what that ‘lb’ really meant to me in terms of my craft and of course, justifying the purchase of MORE!

Currently, there are 2 ways that card stock weight is measured; the European way and the American way and both involve mathematical formulations, that a non-math person such as myself, could get seriously confused with.   Why?  Well the European measurement is based on the two dimensional height and width of one square meter.  Here’s where that fun math-stuff comes – g/m2 (gm/m2, gsm, g/m2).  I know, I know…Math geeks everywhere  just shouted out ‘Can I get a woot woot?!?!?’.  lol  Back in my world though, that math stuff makes me want to turn heel and RUN!

Which brings us to the American measurement…  Much less math involved, which at this hour, is much appreciated!  American measurement is based on the weight of the paper as weighing 500 sheets (a ream) but doesn’t take into account the dimensions of the paper.  Sounds all well and good until your mom asks you ‘Ok, then what weighs more; a ton of bricks or a ton of feathers?’.  Duh, Mom!  A ton of bricks, geesh *eyes rolling*  Like, totally.

For those who like visuals… here’s a lovely lil conversion chart for ya.

What was that, you’re still confused about paper weight?  That’s ok, you’ve got plenty of company!  See those seats over there by the exit door?  Ya, that farthest one is mine…makes it easier to sneak out when that math-stuff gets thrown around the room!

While the card stock weight thing is still confusing, I can tell you a few things.  The heavier and more dense the card stock, the better quality its going to be (and the more you’re going to pay for it).  Typically, us crafters are using card stock in the 60-90lb range.  I compiled a list of the ‘top selling’ brands of card stock  and then tried to find out what the weights were for each of those companies.  *TRIED* being the key word here.

Card Stock Weights – In no particular order
Company Weight
Bazzill 80lb.*
Core’dinations 80lb.**
American Crafts ‘Heavy Weight’***
Worldwin 65 – 104lbs.
Treasures 80 lb.
We R Memory Keepers Unable to Locate
DCWV Unable to Locate
Stampin’ Up 80 lb.
Echo Park Unable to Locate

*When I could find a weight noted, very few of their products state this information

**Most of their product states the weight of the paper

***When listed in this manner – Light-weight = 60lbs., Medium-weight = 70-80lbs., and Heavy-weight = 90lbs.

I’m a firm believer in ‘knowledge is power’ and although (for many of us) this is our hobby, that doesn’t mean we don’t want to make informed decisions.  I’d like to see more companies listing the weights of their paper right along with the dimensions.  Wouldn’t you?  Just do me a favor…hold the mathematics!  Because, yes, my 8th grader is smarter than I am in math.  That one’s for you Sammie, enjoy the moment 😉
