Typical office paper has 80 g/m 2 (0.26 oz/sq ft), therefore a typical A4 sheet (1 ⁄ 16 of a square metre) weighs 5 g (0.18 oz). The abbreviation "gsm" instead of the standard g/m 2 symbol is also widely encountered in English-speaking countries .
The weight of an A-series sheet of a given paper weight can be calculated by knowing the ratio of its size to the A0 sheet. For example, an A4 sheet is 1 ⁄ 16 the size of an A0 sheet, so if it is made from 80 g/m 2 paper, it weighs 1 ⁄ 16 of 80 g (2.8 oz), which is 5 g (0.18 oz).
In Europe and other regions using the ISO 216 paper-sizing system, the weight is expressed in grams per square metre (g/m 2 or usually gsm) of the paper. Printing paper is generally between 60 gsm and 120 gsm. Anything heavier than 160 gsm is considered card. The weight of a ream therefore depends on the dimensions of the paper and its thickness.
Fabric "weight" is often specified as mass per unit area, grams per square meter (gsm) or ounces per square yard. It is also sometimes specified in ounces per yard in a standard width for the particular cloth. One gram per square meter equals 0.0295 ounces per square yard; one ounce per square yard equals 33.9 grams per square meter.
One ream of 20-pound Letter-sized paper weighs 5 pounds (2.3 kg), and a single Letter-sized sheet of 20-pound paper weighs 0.16 ounces (4.536 g), which is equivalent to 75.19 g/m 2. Some metric information is typically included on American ream packaging. For example, 20-pound paper is also labeled as 75 g/m 2.
Most nations describe paper in terms of grammage—the weight in grams of one sheet of the paper measuring one square meter.. Other people, especially in the United States, describe paper in terms of pound weight—the weight in pounds per ream (500 sheets) of the paper with a given area (based on historical production sizes before trimming): for card stock, this is 20 by 26 in (508 by 660 mm ...
Kraft wrapping paper for shipping is also available in 60lb weight. The basis size for these weights is 3000 sqft (same basis as for newsprint, = 500 sheets at 2ft x 3ft per sheet). 1 lb = 453.6g, 3000 sqft = 278.7 sqm -> gsm weight = lb/roll weight * 1.6276; 40lb kraft paper = 65 gsm; 50lb kraft paper = 81 gsm; 60lb kraft paper = 98 gsm
[4]: 67–70, 73–75 The size and proportions of a book depend on the size of the original full sheet. If a sheet 480 by 640 mm (19 by 25 in) is used to print a quarto, the resulting untrimmed pages, will be approximately half as large in each dimension: width 240 mm ( 9 + 1 ⁄ 2 in) and height 320 mm ( 12 + 1 ⁄ 2 in).
