The embodiment of invention relates to the technical field of typesetting, in particular to a typesetting method and device for document containing footnotes. The method comprises the steps that an overlapping area S0 of a text block and a footnote block is determined when an overlap occurs between the text block and the footnote block after typesetting; a first area to be deleted S1 occupied by text contents behind the i-th footnote from the end in the text block is determined; if S0<=S1, part or all of the text contents behind the i-th footnote from the end in the text block are deleted, sothat the text block does not overlap with the footnote block. When the overlap area is less than or equal to the area behind the i-th footnote identifier, the text block and the footer block need to be individually formatted once at most. When the overlap area is larger than the area behind the i-th footnote identifier, reduced heights of the body block and the footer block are calculated, so thatthe text block and the footnote block are individually typeset once, and a great amount of time is not consumed, so that the speed of typesetting is increased, thereby improving the efficiency of thetypesetting.
