How long should an introduction paragraph be for a college essay?
Is it 4-5 sentences or shorter?
4-5 is a decent goal. It CAN be longer, if needed (though how long is reasonable really depends on the length of your paper). I think going shorter would be pushing it. Consider that your introduction is supposed to draw the reader in, give some kind of background to what you’re doing, and then state your hypothesis/argument/the point of your paper. That’s kind of a tall order in anything under 5 sentences and, depending on things like your topic and writing style, might be difficult in just 5 sentences too.
