The length of thread on a reel can vary widely depending on the type of thread and the size of the reel. For example, standard sewing thread spools may contain anywhere from 100 to 1,000 yards (or more) of thread, while larger industrial spools can hold thousands of yards. Specialty threads, such as fishing line or embroidery thread, also come in different lengths tailored to their specific uses. Always check the packaging for precise measurements.
