Vibratory Screens come in a variety of sizes. They can range from 4' to 12' wide and 6' to 32' long. The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width.

An efficiency of 99% will equate to a significant loss of capacity. Efficiency is the ratio of undersize material in the feed that actually passes from the media to the undersize material that should pass from the media. This ratio is desired to be , however this is not possible due to the factors affecting the process.
