Frontal Sq'

As far as the measurement is concerned, I don't think the curve matters. It's mostly just how high x how wide. If you have an Airstream or similar, you could do the math to account for the rounded corners.

Not worth figuring the difference especially if the curves take away from the usefulness inside.

People I know who have had high vs low profile enclosed snowmachine trailers say that in the end they can't tell any difference in mileage or anything else except that's a PITA to bend over in a shorter trailer.

Use the 'flat figure'.....width x height

Curves will just make it less.

Besides..frontal area is least of concerns.
Trailer GVWR, tongue weight are more important factors when it comes to 'can it be towed'

So would that be "I don't know? I didn't ask if I can tow it, I was looking for a formula.

There has to be a reduction due to the curve, I was just wondering if there was a formula, cause I don't know what math to do.

It has a curved front profile instead of it being flat, it isn't any shorter.

Do a search under drag coefficient. Maybe look under vehicle drag coefficient. If you have a good shape a trailer may be 50% of a totally flat surface. However a lot depends on the shape of the tow vehicle creating the hole in the air ahead of it. What is the ultimate question you are trying to solve? Does your Honda have a limit on the square foot it's allowed to tow?

IMO you bring up an important point and that is not how much a "hole" the TV "punches" in the airflow, but how much turbulence it creates behind the TV that then impacts the trailer front. Typical drag coeficients are based on a uninterrupted parallel air flow hitting the surface which is far from the case in the frontal areodynamics of a TT being towed by a vehicle.

I agree, just use the height x width as a decent approximation and I would probably take the height from the ground and not the bottom of the trailer since tires, any exposed undercarriage coupled with the TV obstructions would probably negate any open area below the floor of the trailer.

You need calculus to do this calculation. I took Calculus in college. I got an A. I can't remember any of it now. If you don't want to take two semesters of Calculus you might want to try something like this website:

Cylinder surface area.
