How long should an introduction of a 2-3 page essay be?
an introduction of a 2-3 page essay can be about half a page.
And introduction is usually one paragraph, as is the conclusion. The rest of the paragraphs are there to prove that your thesis statement is true. (Your thesis statement is normally placed at the end of your introductory paragraph.)

The length of an introduction for a 2-3 page essay can vary, but typically it should be around 5-7 sentences or roughly half a page. However, it's important to note that the length of your introduction should not be measured in terms of the number of sentences or words, but rather by the purpose it serves. Your introduction should grab the reader's attention, provide some context or background information on the topic, and clearly state your thesis or main argument.
To determine the appropriate length of your introduction, consider the complexity of your topic and the amount of information you need to provide to set the stage for the rest of your essay. If your topic is fairly straightforward, you may be able to provide the necessary context in a shorter introduction. However, if your topic is more complex or requires additional background information, you might need a slightly longer introduction.
When brainstorming and writing your introduction, focus on being concise and precise. Avoid unnecessary fluff and stay focused on the main ideas you want to convey. Remember that the introduction is just the starting point of your essay and should lead smoothly into the body paragraphs where you present your arguments and evidence.
