What is how big is middle earth?

Middle Earth is a fictional world created by J.R.R. Tolkien in his popular book series The Hobbit and The Lord of the Rings. It is often depicted as a vast continent with various kingdoms and races of creatures inhabiting it. However, the exact size of Middle Earth has never been defined by Tolkien or his books. Therefore, its physical dimensions remain subject to interpretation by individual authors, filmmakers, and fans. Some have estimated it to be about the size of Europe, while others have speculated it could be much larger. Ultimately, the size of Middle Earth is left up to the imagination of the reader or viewer.
