When towing there are three things to consider . . .

[1] Towing Vehicle
You need to know and understand GVWR (Gross Vehicle Weight Rating). It is important to towing because it tells you explicitly the maximum weight of cargo and passengers you can carry safely in your pickup truck, SUV, or CUV. GVWR is the total combined weight of the truck, including all passengers, fuel, fluids and cargo. GVWR is engineered in when the vehicle is manufactured and remains constant, regardless of what you tow.
Because tongue weight must be included in the GVWR, you will need to know how much weight capacity you need to have “left over” for when you hook up your trailer.
For example, if you have a 5,000-pound truck with a 6,300 pound GVWR, you can safely carry 1,300 pounds in the vehicle. If you are towing a trailer with a 300-pound tongue weight, the amount of passengers and gear you can carry is reduced to 1,000 pounds.
You most likely already own your vehicle and that will be a major factor in deciding what size hitch & trailer to get.
[2] Trailer type & size
For some this is an obvious decision, for others maybe not. Trailers are divided into several classes and the two most common for consumers are Cargo/Enclosed trailers & Utility/Open trailers. Both Cargos and Utilities are offered in a wide range of sizes. Obviously, your first consideration is the dimensions and weight of the biggest and heaviest stuff you may need to haul.
It may help to see the available sizes for both Cargo Trailers (enclosed) and Utility Trailers (open). We set up two tables below by width and length. Then we looked at the last 12 month of sales data and ranked each size by number of units purchased. To show popularty for each size (Width x Length), we plotted the rankings on the table. From the chart below you can see that our top three size sellers for cargo trailers were: 7x16, 6x12, and 6x10.
