How does size affect paper airplanes?

Question

the flight of paper airplane

Answer 1

I am No engineer by any sense of the word.. i do know that your Wing Area..which will affect the Lift you need to fly your airplane,
will have to be directly proportional to the Planes Mass and Weight(Size) in order to achieve the Lift.If you cannot allow for larger wingspan(Area) You can Modify the wings
to allow the Volume of air passing under the wings area to increase,
allowing for a larger size plane to fly.

Answer 2

The stiffness and weight of the paper itself rules the size of airplane and its performance. Reaching the balance between size and weight and perfecting a fold to carry this balance is the work of the designer and builder.

Answer 3

A bigger plane means it weighs more, and will be more prone to falling. Since paper airplanes don't generate any thrust while in flight, you would have to throw it harder to make it fly.

Answer 4

If it is too big, it cannot get enough loft to fly well
