An ideal screen gain is set as 1.0. Basically, that means a screen with 1.0 gain reflects the same amount of light as if it was a white board. Such a screen diffuses light evenly in all directions, and the amount of light is bright enough for a crisp and vivid image, visible from a wide variety of viewing angles.
Is a higher gain better projector screen?
A screen with a gain measurement of greater than 1.0 infers that the image projected back off of the surface is brighter than the image being projected at the surface. For example; a projector screen with a gain of 1.5 will project back the light 1.5x brighter than the light being projected at the screen.

Tape a small piece of the reference to your screen, light it with the PJ, measure the reflected light of each with a spot-lightmeter, then calculate the gain. Stewart Filmscreen samples are probably accurate as far as gain rating.Does projector screen matter for 3D?
Do I need a special screen for use with a 3D projector? You do not need a special screen in order to view images from a typical 3D projector. While some features may help enhance the image, a special screen is not required when using a 3D projector.

For screens that are projected upon (like cinema, home cinema), it quantifies how much light is reflected (to the center of the room). This depends on the amount of light produced (lumens), the size of the screen and the screen gain.
