5.3 Dimensions of item
5.3.1 The third element of the physical description area is a statement regarding the dimensions
of the item, expressed in terms of centimetres rounded up to the next whole centimetre. The term is
abbreviated as "cm" (or its equivalent in another language and/or script).
5.3.2 The dimensions of two-dimensional items (wallcharts, microfiches, slides, transparencies,
pictures, etc.) are given in the form height x width. For circular two-dimensional items (with the exception
of sound discs and videodiscs, see 5.3.4) the diameter is given, followed in parentheses by the
abbreviation "diam." or its equivalent in another language and/or script. For oval two-dimensional items the
length of the vertical axis is given, followed in parentheses by "oval" or its equivalent. Dimensions relate to
the sheet or other surface, but when there is a significant difference between the dimensions of the sheet
and the dimensions of the printed area, the latter may be given in a note (see 7.5).
e.g.
. – 1 wallchart : col. ; 24 x 48 cm
. – 20 slides : col. ; 5 x 5 cm
. – 1 picture : col. ; 36 cm (diam.)
. – 3 stereograph reels (21 pairs of fr.) : col. ; 9 cm (diam.)
When the item consists of a set of such two-dimensional units and the individual units vary in size, the
dimensions of the largest are given followed by "and smaller" (or its equivalent in another language and/or
script).
e.g.
. – 6 wallcharts : col. ; 60 x 98 cm and smaller
Alternatively, the dimensions of all the units may be given in a note (see 7.5).
For a folding sheet, two dimensions statements are given.
e.g.
. – 1 wallchart : col. ; 48 x 90 cm folding to 24 x 15 cm
5.3.3 The dimensions of three-dimensional items (dioramas, models, etc.) are given in the form
height x width x depth, or when this is inappropriate, height alone. Very complex dimensions statements
may be given in a note (see 7.5) or omitted.
e.g.
. – 1 diorama : various materials, col. ; 9 x 30 x 20 cm
. – 1 model : plastic, b&w ; 15 cm
When an integral container or mounting is to form part of the description, two dimensions statements may
be given. Alternatively, the dimensions of the whole item, including container or mountings, may be given
alone.
e.g.
. – 1 model : plastic, pinky beige ; 55 cm on stand, 30 cm
. – 1 diorama : col. ; in glazed case, 35 x 60 x 24 cm
