How big is size B1 ?
Some illustrated demonstrations
A phrase such as 'paper size 330x220' means very little to me. I do not think I am alone in this. I have got used to A4 ~ and C6 ~ and more recently ~ very late in life ~ I have become acquainted with some larger sizes. I find that very often items on the WWW have no scale ~and comments from other buyers indicate this very frequently. I have tried to rectify this on any sites I produce ~ such as this ~ and in our sister site at [busybusy.shop]. Here are a few pictures to help others who are in the same boat.

ISO B1 is a useful size to remember if you are involved with decorative papers (such as that illustrated above) They are printed on litho presses, and B1 is the largest practical size for a reasonably expensive printing press. (Doubling size of paper does not double the cost of the press - it probably quadruples it, or more.) B1 is a difficult size to handle without damaging it, and rolling is not economical of shelf space. For this reason most decorative paper is sold in sheets of half the length of a B1 sheet ~ which is half the area. (I have been very careful not to say half the size ~ which is ambiguous and deceptive.) Half the area of a B1 sheet is called ISO size B2.
ISO Paper Size ~ B2 707x500 ~ appx 28"x20"
There is some confusion over this, since some shops refer to decorative paper of this size as a sheet. Others refer to a sheet as being B1 ~ the size at which it is printed. Purchasers need to read the listings carefully ~ as well as heed the postage costs which can be very great. To cut down on postage a B2 sheet is usually folded twice to give a B4 sheet. This is, within a tiny fraction of the length, is the maximum permitted size for a UK Large Letter. Which means that a B4 sheet cannot be wrapped with any protection without it having to be sent as a Small Parcel ~ for which UK postage starts at over £3.
Grain is important for some craftworkers in paper ~ bookbinders in particular ~ and it is most likely that the grain of the printed B1 sheet is long-grain. Many patterns ~ not all! ~ are right reading when looking at the sheets with grain running vertically ~ note the ships in the pictures above. In that picure the paper is rolled against the grain. All this can be summarized by noting that all odd numbered B sheets are long grain ~ even numbered B sheets are short grain.
