On each page your material should fit within a rectangle of 18 x 23.5 cm (7 x 9.25 in.), centered on a US letter page (8.5x11 inches), beginning 1.9 cm (.75 in.) from the top of the page, with a .85 cm (.33 in.) space between two 8.4 cm (3.3 in.) columns. Right margins should be justified, not ragged (except for the references section). Beware, especially when using this template on a Macintosh, Word can change these dimensions in unexpected ways. Please be sure your word document and pdf are US letter and not A4. If your pdf or paper are formatted for A4, the submission will be returned to you to fix within 2 days.
