In the United States, the average size of a brick is 8 inches long, 4 inches wide and 2 ¼ inches deep. Bricks vary in size across the world. However, regardless of its size, the length of a brick is typically twice the width.
As a bricklayer uses a trowel in one hand, bricks are typically light enough to be easily handled in the opposing hand. The use of bricks dates back more than 10,000 years. Popularity of brick as a building material has risen and fallen over the centuries. Currently, brick is used most frequently in smaller structures and as a decorative accent.
