Some assignments are given page count requirements instead of word count. A normal, typed, double-spaced essay without footnotes is said to yield approximately 250 words per page. Page count requirements are open to cheating by doing things like extending the line height, widening all four margins, increasing the font size or using a wider-style font, using footnotes, and other style elements that help spread the content over the pages. While this may satisfy the requirement, keep in mind that your instructor is expecting a certain level of content in the essay, and an incomplete essay stretched over the required amount of pages is still an incomplete essay. Conversely, an essay that blathers on will still seem to blather even if the student creatively crams more words into a smaller space.
An Essay on Criticism is one of the first major poems written by the English writer Alexander Pope (1688–1744). It is the source of the famous quotations "To err is human, to forgive divine," "A little learning is a dang'rous thing" (frequently misquoted as "A little knowledge is a dang'rous thing"), and "Fools rush in where angels fear to tread." It first appeared in 1711  after having been written in 1709, and it is clear from Pope's correspondence  that many of the poem's ideas had existed in prose form since at least 1706. Composed in heroic couplets (pairs of adjacent rhyming lines of iambic pentameter ) and written in the Horatian mode of satire, it is a verse essay primarily concerned with how writers and critics behave in the new literary commerce of Pope's contemporary age. The poem covers a range of good criticism and advice, and represents many of the chief literary ideals of Pope's age.
