In this formula, the 16 and 9 values are derived from the aspect ratio of modern televisions, which is 16:9. This formula is derived from the formula to calculate the hypotenuse of a triangle.

65″ TV screen width = 16 × 65 / √(16² + 9²) 65″ TV screen width = 16 × 65 / √(256 + 81) 65″ TV screen width = 16 × 65 / √337 65″ TV screen width = 16 × 65 / 18.36 65″ TV screen width = 16 × 3.54 65″ TV screen width = 56.7″

Also known as a “ladder hinge,” a removable wedge allows the case to remain open at 90 degrees, making it ideal for displaying product samples.

The table below shows dimensions for common TV sizes, including diagonal, width, and height dimensions, in inches. This is useful for finding the dimensions of a 16:9 TV screen when you know the diagonal measurement.

GWP Protective typically supplies businesses and professionals with their case requirements. While we have no minimum order quantities—you can have a single case with foam inserts—buying in larger volumes significantly improves the price. For a one-off empty case (e.g., for a hobbyist), it may also be worth looking at specialist online retailers. If you are unsure, please ask.

SPI cases are available in eight standard colours: black, white, navy, yellow, blue, green, grey, and ruby (red). Custom colours are available, although subject to relatively high order volumes. It is also possible to coordinate or contrast the catch colours.
