IBO says the extended essay should be written in a clear, correct and formal academic style, appropriate to the subject from which the topic is drawn. 


The upper limit is 4,000 words for all extended essays. This upper limit includes the introduction, the body, the conclusion and any quotations, but does not include:

  • acknowledgments

  • the contents page

  • maps, charts, diagrams, annotated illustrations and tables

  • equations, formulas and calculations

  • citations/references (whether parenthetical or numbered)

  • footnotes or endnotes

  • the bibliography
