There unfortunately isn't a guide to tell us the size needed for your specific trailer, but it's really easy to measure for the correct size lug nuts. You'll want to use a set of calipers # PTW80157 to measure the diameter of the wheel stud, including the threads and then measure the pitch by counting the threads in one inch of space on the stud. The most common sizes are 1/2"-20, 9/16"-18, and 5/8"-18. The 1/2"-20 wheel studs are typically used on small-medium duty trailers whereas the 9/16"-18 and 5/8"-18 wheel studs are used on larger duty trailers. I've attached a few of the most commonly used lug nuts below, but if you want something a bit different just let me know your preferences and the size needed.
