How Much Does a Standard Red Brick Weigh?

A standard 8-inch by 2 1/4-inch by 4-inch red clay brick weighs about 5 pounds. Bricks are used for a variety of building projects, such as walls, patio floors and pathways.

Bricks are an ancient construction material. They were first developed over 6,000 years ago when straw or grass was added to the clay to help prevent cracking as the bricks baked in the sun. Bricks with uniform sizes and shapes were not produced for another 2,000 years. At this time, brick makers began using firing techniques instead of the sun's heat to dry their products. Modern bricks, made from shale and clay, are fired in kilns that reach 2,000 degrees Fahrenheit.
