From the documentation of
elsarticle, section 12
The authors can format their submission to the page size and margins of their preferred journal.
elsarticle provides four class options for the same. But it does not mean that using these options you can emulate the exact page layout of the final print copy.
1p: 1+ journals with a text area of 384pt × 562pt or 13.5cm × 19.75cm or 5.3in × 7.78in, single column style only.
3p: 3+ journals with a text area of 468pt × 622pt or 16.45cm × 21.9cm or 6.5in × 8.6in, single column style.
twocolumn: should be used along with
3p option if the journal is 3+ with the same text area as above, but double column style.
5p: 5+ with text area of 522pt × 682pt or 18.35cm × 24cm or 7.22in × 9.45in, double column style only.
Following pages have the clippings of different parts of the title page of different journal models typeset in final format.
Model 1+ and 3+ will have the same look and feel in the typeset copy when presented in this document. That is also the case with the double column 3+ and 5+ journal article pages. The only difference will be wider text width of higher models. Therefore we will look at the different portions of a typical single column journal page and that of a double column article in the final format.
So either you use
The output is very similar, so I show only the one with the first document class line.
