The SYB Picture Frame is, in general, not large enough to provide effective shielding from a smart meter. Instead, for that purpose, we recommend our SYB Poster Frame Liner, which comes in multiple sizes.
The SYB Picture Frame can hold two separate 5 inches by 7-inch photos or pictures, and it is specifically designed to be placed in front of devices like WiFi router and cell or cordless phones, so it deflects the radiation emitted by devices in the opposite direction, and protects humans in front of it.
