One of the most important technical requirements for your IB Internal Assessments (IAs) and Extended Essay (EE) is the word count. Exceeding or falling short of the word count can affect how your work is assessed—and ultimately, your grade. This guide explains the key word count limits, what counts toward them, and how to manage your writing effectively.
Why Word Count Matters
IB examiners will not read beyond the stated word limit for an IA or Extended Essay. If you exceed the limit, any content past that point will not be considered in marking. This means critical analysis, evaluation, or conclusions could be ignored—costing you valuable marks. On the other hand, writing too little can indicate insufficient depth, reducing your score.
IB Word Count Guidelines by Assignment Type
Internal Assessments (IA)
Word count limits vary by subject. Below are common examples:
- Biology IA – Maximum 2,200 words
- Chemistry IA – Maximum 2,200 words
- Physics IA – Often up to 3,000 words
- Geography IA – Maximum 2,500 words
- Psychology IA – Maximum 2,000 words
- Business Management IA – Typically 1,500–2,000 words
Most IAs fall within a 1,500 to 2,500 word range, depending on the subject and level (SL/HL).
Extended Essay (EE)
- All subjects – Maximum 4,000 words
This is a strict upper limit. The IB recommends aiming close to this word count to ensure sufficient depth and analysis.
