The scale is determined by placing the kite in a cube per the scale above. Placing the kite diagonally in the cube is valid.

For example - a Nano kite must fit inside a .4 inch cube. A plane surface (flat) kite that is .5 inches by .4 inches would fit inside a Nano scale cube on the diagonal and thus would still be a Nano sized kite.

* A plane surface Magnum kite could be as large as 16 inches x 12 inches; by many definitions a kite with any dimension that is over 12 inches is not considered "miniature". However even Charlie Sotich occasionally made kites in the upper size range of a Magnum miniature kite. Miniature Kite competition usually do not allow kites larger than Hand sized.
