How heavy is the Mona Lisa painting?

The Mona Lisa, painted by Leonardo da vinci, weighs approximately 18 pounds (8.2 kilograms). This weight is due to its wooden panel support, which is made of poplar wood. The painting's dimensions are about 30 inches by 20 7/8 inches (77 cm by 53 cm), contributing to its overall heft despite its relatively small size.
