Different political science journals have different article formats with different word/page limits. Consequently, whenever you want to submit an article to a journal, the first thing to look up is the exact word limit.
In order to get a sense of the different article formats and word limits in political science journals, I have created an overview. The overview shows word limits for long articles, short articles and review essays/articles.
The overview currently consists of 65 journals and I will most likely add more journals (and more features) in the future. Do reach out on Twitter or drop me a mail if you got any feedback or if there is a specific journal of relevance to political scientists that I should add to the overview.
Last, the overview is sorted by impact factor (obtained with the excellent scholar package in R).
