BALANCE & WEIGHT
Thick paper can glide easier than thin paper if the wings can support it. An airplane has a point where it balances; it's called center of gravity. Another point called neutral point exists where the nose lines up perfectly with the rest of the plane. The majority of the weight of the paper air plane needs to lie some place above the neutral point.

THE SHAPE
For the traditional dart shape paper airplane, regular paper works best.
Paper airplanes with longer wings such as rectangular shapes needs a heavier material such as cardboard to support the force of air on the wings.

HOW IT FLYS
When a paper airplane is designed the builder folds the sheet of paper to provide maximum wingspan to support the plane for longer flight. Normal paper airplanes may be created with different wing designs for speed or longer flight. Some designers choose to add a small weight to the plane to keep it in the air, for example a staple or paperclip.

Biggest Wingspan
The record holder for the largest paper airplane had a wingspan of 40 feet and 10 inches. The plane flew over 114 feet before crashing into a wall.
