    The same as iit means anywhere else.    http://www.paper-papers.com/paper-weights.html

    ?

     

    2. The workbook cover is 250 grams two sides chrome matte laminated, what does it mean in U.S. standards.

     

    I am still not sure what you mean because it''s a Worldwide standard. But that is card thickness as opposed to page thickness.

     

    3. The width is 210 mm and height 279.4 mm, what are U.S. the measurements?

  • thank you.

    In my country wood free means 5% wood 95% Synthetic. Is there a special terminology in the U.S. for this kind of paper?

     

    I was told that in the U.S 250 grams of cover paper are measured by caliper (thickness) not weight. and it was calculated as 60# offset . I would be very helpful if you could explained how the calculation was done. The page size is 8.25x11.

    5% wood it not wood-free. But I am not in the USA, but what do you mean by synthetic? There's often cotton in some paper (and china clay) and some banknotes have no woodpulp in them at all. I think you are asking due to sustainability? Most pine is planted and replacements replanted to be turned in to paper nowadays (and other objects.) Many paper products use part or whole recycled paper, but unless it's bleached, which is not a very 'green' process, it's not white.

    But grams is a weight, Used worldwide. It originated in France. All the paper and card I have bought is gauged in GSM. But some places that sell in vast bulk do sell by the pound weight.

     

    and it was calculated as 60# offset .

     

    60# is a bit meaningless. But yes it can be confusing. This may help >>    http://paperworks.com/about-paper-weights

    I am not sure why you are asking. Lulu's Print On Demand books are books in every respect. Create a Private one and order a Proof.

    A common measurement for the heaviness of paper in the US is to indicate the weight of a ream (500 sheets) of a standard size. Therefore, 500 sheets of 60# paper would weigh 60 pounds. 24# paper of the same size would be thinner.

    For example, ordinary office copy paper has a standard size of 17” x 22″ (uncut) and this is the size that is weighed for 500 sheets. If 500 sheets of this size weigh 20 lbs, then the paper is classified as being 20lb or 20#.

    Paper sold in gram units is similar. The weight in this case is usually expressed as Grams per Square Meter or GSM. This is the weight of a square meter of the paper in question. Just as with the pound weight scale, the higher the GSM number, the heavier the paper is. 

    Paper itself can be made of anything fibrous (it's actually related to felt). Linen is often used to make very fine papers, while ordinary cotton rags can be used as well. A paper with a "high rag count" is considered to be of better quality than paper with a low rag count or paper made entirely from pulp. The latter is made from wood pulp and is generally considered to be the lowest quality paper (hence the term "pulps" used to describe many cheap magazines published decades ago, which saved money by printing on the cheapest paper possible).

    Paper made from linen can last a very long time. I have publications here that were printed in the early 19th century with pages that are as white and flexible as the day they first appeared.
