Sounds like you are looking for a replacement inner coupler tube for a gooseneck trailer and are wondering how to measure. You'd just need to measure the inner width of the opening and we'd be able to help you figure out what you'd need. The most popular size is the 4 inch size like the part # BD0288660300.
