How Much Does a Standard Red Brick Weigh?

The average weight of a regular red brick in the United States is 4.5 pounds. The “standard” brick dimensions in the United States are 3 5/8 inches in depth, 2 1/4 inches in height, and 8 inches in length. According to the specifications of ASTM International, formerly known as the American Society for Testing and Materials, it is one of numerous brick sizes. Modular, giant modular, jumbo standard, queen, Roman, Norman, closure, and utility are among the additional ASTM brick sizes. It should be noted that various nations do not necessarily adhere to ASTM regulations and have their own standard brick measurements.

“Normal” Red Bricks

In the United States, a “standard” brick refers to a certain brick unit size rather than indicating that it is the most regularly used brick. The modular brick is the most often used brick for general mason work in the United States. The modular brick has an average weight of 4.2 pounds, a depth of 3 5/8 inches, a height of 2 1/4 inches, and a length of 7 5/8 inches, which is just slightly shorter than the modular brick. One of the heaviest ASTM standard bricks is the thru-wall brick, which measures 7 and 5/8 inches by 7 and 5/8 inches by 15 and 5/8 inches and weighs a huge 41.5 pounds.

Other US Brick Sizes

Several different brick unit sizes exist between modular, standard, and thru-wall dimensions. The following are the dimensions and sizes of the bricks, as well as their average weight.

3 5/8 inches by 1 5/8 inches by 11 58 inches; 4.7 pounds
Jumbo modular dimensions: 3 5/8 x 2 3/4 x 7 5/8 inches; 5.1 pounds
Queen dimensions: 3 1/8 x 2 3/4 x 9 5/8 inches; 5.6 pounds
Standard jumbo dimensions: 3 5/8 x 2 3/4 x 8 inches; 5.9 pounds
Norman: 3 5/8 by 2 1/4 by 11 5/8 inches; 6.4 ounces
Ambassador: 3 5/8 by 2 1/4 by 15 5/8 inches and 8.8 pounds
Utility: 3 5/8 by 3 5/8 by 11 5/8 inches and 10.2 pounds
12.5 ounces; 3 5/8 inches by 3 5/8 inches by 15 5/8 inches.
14.1 ounces; dimensions of 3 5/8 inches by 7 5/8 inches by 7 5/8 inches
How Many Bricks Does a Wall Require?

To determine the number of bricks required to cover a wall, you must first calculate the wall’s square footage by multiplying its height by its width in feet.

Example: 10 feet x 8 feet Equals 80 feet

Next, get the square footage covered by each brick by multiplying its height by its length and dividing by 144. To account for the mortar, add 3/8 inch to the height and width measurements. Using modular bricks as an illustration, the following formula applies:

Example: brick and mortar width equals 2 1/4 inches plus 3/8 inches, which equals 2 5/8 inches

Brick-and-mortar length is 7 5/8 inches plus 3/8 inches, which equals 8 inches.

Brick square feet = (8 2 5/8) 144

Brick foot squared = 21 144 =.1458

Finally, divide the wall’s square footage by the brick’s square footage to determine the number of bricks required to cover the wall.

80 multiplied by.1458 equals 549 bricks.

How Bricks Are Made in Red

Typically, bricks are formed from shale, which is an easily fractured type of rock. Shale is initially exposed to the elements to make it more manageable. After two years, it is transported to the manufacturing facility where it is processed into powder by machines. The clay is then combined with water and squeezed into a long, continuous, rectangular block.

The block, also known as a slug, proceeds through a second machine that cuts it into 5-foot-long pieces. After that, it passes through a second machine that further reduces it to its ultimate dimensions. New bricks are placed in a drying chamber for two days in order to remove excess moisture prior to burning.

Once the bricks are sufficiently dry, they are heated to approximately 2,000 degrees Fahrenheit in a kiln. After one day and a half, the bricks are complete. At this point, the once-gray shale slugs had acquired the distinctive brick-red hue.

Standard Brick Dimensions by Country

As previously stated, different nations have their own “standard” brick sizes. The following measures are in millimetres (mm) because the majority of other countries use the metric system.

Russia: 120 mm x 65 mm x 250 mm
United Kingdom: 102.5 millimetres by 65 millimetres by 215 millimetres
Germany: 114 mm x 71 mm x 240 mm
China and India: 107 by 69 by 228 millimetres
U.S. modular bricks are 92 mm x 57 mm x 194 mm in millimetres. Standard-sized bricks in the United States are 92 mm by 57 mm by 203 mm.

Red bricks are available in a variety of sizes and weights. Find out the weight of a typical red brick and other brick-related information.
