The following guidelines can be used to estimate the approximate length of an article:

• An average article opening (title up to and including the abstract) is 1/2 a page (depending of course on the number of authors and affiliations. Approx. 5 authors per line and 1 line for each affiliation). Examples can be found in the journal.
• A journal page with only typeset text contains about 750 words (2 columns X 48 lines) (or about 4500 characters including blanks).
• A 1-column figure takes up about 1/5 page (19 lines), a 2-column figure about half a page (24 lines).
• A 1-column table takes up about 1/5 page (19 lines; 5 entries is equivalent to ca. 4 lines), a 2-column table takes up about half a page (depending of course on the number of entries).
• A 1-line free-standing equation is equivalent to about 30 words (or about 180 characters or 4 lines).
• The space taken up by a figure can be estimated by reducing its size to the width of 1 column (7.5 cm) and then see if the figure is still legible. If not, the legends to the axes and the lettering should be enlarged, so the figure still fits in 1 column. If this is not possible the figure should be placed in two columns (maximum width 16 cm).
• We recommend you to take a look at the journal, since this will give the best "feel" regarding the layout of the title page, figures and tables.
