BRIEF HISTORY
The IS0 Recommendation R 353, Method of Expression of Dimensions of Processed
Writing Paper and Certain Classes of Printed Matter, was drawn up by Technical Committee
ISO/TC 6, Paper, the Secretariat of which is held by the Association Française de Normali-
sation (AFNOR).
Work on this question by the Technical Committee began in 1958 and led, in 1960,
to the adoption of a Draft IS0 Recommendation.
In October 1960, this Draft IS0 Recommendation (No. 397) was circulated to all the
IS0 Member Bodies for enquiry. It was approved, subject to a few modifications of an
editorial nature, by the following Member Bodies :
Belgium India Republic of
Brazil Iran South Africa
Chile Japan Rom ani a
Czechoslovakia Mexico Sweden
Denmark New Zealand Turkey
Germany Poland United Kingdom
Greece Portugal
Two Member Bodies opposed the approval of the Draft:
France, U.S.S.R.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0
Council, which decided, in December 1963, to accept it as an IS0 RECOMMENDATION.
FOREWORD
The object of the present IS0 Recommendation is to facilitate communications between
producers, converters and users by establishing rules relating to the designation of sizes of
papers in sheets, loose or bound, when ruled or printed by any process; pads; leaflets;
notebooks, etc.
It applies to all stages of production.
It does not necessarily apply to all classes of ultimate users: librarians, archivists, etc.
The method of expression of dimensions and direction of manufacture of unprocessed
papers is the subject of IS0 Recommendation R 217-Method of Expression of Dimensions
and Direction of Manufacture of Unprocessed Writing and Printing Paper.
The present IS0 Recommendation cannot take into account all possible eventualities.
For example, the recommendation of section 4 presupposes that the line of printing is
always horizontal.
If there is any doubt concerning the possible uses, or the exact meaning of the present
Recommendation, especially in unusual circumstances, the supplier should be given
precise data in addition to the IS0 designation, and a pattern of what is required, in the
form of either a sample or a diagram.

METHOD OF EXPRESSION
OF DIMENSIONS OF PROCESSED WRITING PAPER
AND CERTAIN CLASSES OF PRINTED MATTER
1. SCOPE
This IS0 Recommendation gives methods of expressing the dimensions of processed papers in
such a manner that the shape of the finished article is indicated.
" Processed " in this context means converted, e.g. by the printer or stationer; examples of such
processing are printing, ruling, punching, folding and stitching.
2. SEPARATE SHEETS IN THE FLAT (PRINTED, RULED, PUNCHED, ETC.)
2.1 General
2.1.1 IS0 sizes
Designate the IS0 size by its symbol.
2.1.1.1 The symbol without any additional letter means that the shorter edge is parallel to
the direction of reading or writing.
Example (see Fig. 1): A4
2.1.1.2 The symbol followed by the letter L means that the longer edge is parallel to
the direction of reading or writing.
Example (see Fig. 2): A4 L
designation :

FIG. 1 FIG. 2
2.1.2 Sizes other than IS0 sizes
Designate the size by its two dimensions, in millimetres or in inches, separated by the
sign x , giving the smaller dimension first.
Where there is danger of confusion, for example in transactions between countries
using the metric system and those using inch dimensions, the unit should be stated
(e.g. for the metr
