The average brick measures 3-5/8″ x 2-1/4″ x 8″, weighing 4 1/2 pounds on average. Larger quad bricks weigh 14 pounds on average, while engineering bricks have a weight of 5.1 pounds on average.

Heavier bricks are generally able to support heavier weights and endure greater weight impact than lighter bricks.

Here, you may have got a simple answer for “how much does a brick weigh?”. Let’s jump to the next section and cover some subtopics regarding the same.

How are Bricks Made?

Bricks are usually composed of shale, a sort of rock that breaks easily. The shale is exposed to the elements, making it easier to work with. It is transported to the factory after two years and ground into a powder using machines.

It’s then combined with water and compressed into a long continuous rectangular clay block by being pressed together.

A brick is formed by a steel block that is cut into 5-foot-long portions, which are then passed through another machine to slice it into smaller blocks. The block next travels through another machine, which cuts it down to its final measurements.

To prepare the bricks for firing, they’re placed in a drying chamber for two days to remove any excess water.

To complete the process, the bricks are put in a kiln for 2,000 degrees Fahrenheit. The bricks are completed after one and a half days. By this time, the formerly gray shale slugs have acquired the distinctive dark red color of bricks.

Standard Brick Sizes Around the Globe

Because most other countries use the metric system, the following measurements are in millimeters (mm).

  • Russia: 120 mm x 65 mm x 250 mm
  • United Kingdom: 102.5 mm x 65 mm x 215 mm
  • Germany: 114 mm x 71 mm x 240 mm
  • China and India: 107 mm x 69 mm x 228 mm
  • U.S.A.: 92 mm x 57 mm x 203 mm

How to Calculate the Weight of a Brick?

To figure out the weight of bricks, use the following formula:

Weight = Volume x Density

  1. Using a ruler, measure the dimensions of the brick. For instance, assume that the brick measurement is 8 by 2 by 4 inches.
  2. To find out the volume or how much space the brick will take up, multiply the length, width, and height of the brick. In this example, 64 cubic inches is the volume of the brick.
  3. To convert from cubic inches to cubic meters, multiply the volume in cubic inches by 0.000016. The brick volume in this example is 64 x 0.001024 = 0.001024 cubic meters.
  4. Next is to determine the density of the brick. The density of a typical red brick is 1,922 kg/m 3 in this example.
  5. To figure out the brick weight, multiply the volume by the density. In this case, the weight is 0.001024 m3 x 1,922 kg/m3 = 1.968 kg.
  6. To convert a brick’s weight in kilograms to pounds, multiply it by 2.204. The brick weight in the example is 4.337 pounds.

How Many Bricks are Required to Make a Wall?

To figure out how many bricks are required to cover a wall, you’ll need to first calculate the wall’s square footage by multiplying its height and width in feet.

Next, determine the total square footage of each brick by multiplying its height by its length and dividing it by 144. To account for the mortar, add 3/8 of an inch to the height and width measurements.

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

Example: 10 feet x 8 feet = 80 feet

In this example, we are considering modular bricks and the formula is as follows:

Brick-and-Mortar width = 2 1/4 inches + 3/8 inches = 2 5/8 inches

Brick-and-mortar length = 7 5/8 inches + 3/8 inches = 8 inches

Brick ft2 = (8 × 2 5/8) ÷ 144

Brick ft2 = 21 ÷ 144 = .1458

At last, 80 ÷ .1458 = 549 bricks

How to Select Bricks?

We discussed the “how much does a brick weigh?” section along with its manufacturing and specifications but how will you choose the rights ones?

When it comes to choosing your bricks, a masonry professional is the best option.

However, while there are some standards that can assist you in determining what you should take when shopping at the hardware store, picking your bricks is best left to a mason.

The following tactics may help you keep a handle on brick usage.

  • For paving purposes, prefer paver bricks. They’re more rust-resistant and have a greater iron content than most other bricks, making them ideal for flooring. These are also simpler to clean off of tar. When buying paving bricks, make sure you get ones with the dimensions you need.
  • If you want your wall to have a higher load-bearing, choose engineering bricks. They have holes in the middle and are manufactured to support more weight while taking up less room. Engineering bricks are frequently given special treatments or methods of brick production that improve their strength.
  • Common burnt clay bricks are ideal for general building tasks. Just so you know, these bricks don’t have holes in them. You may use these to make a beautiful brick artwork or a fire pit in your garden.
  • Roman and Norman’s bricks are used to accentuate the long, thin appearance of particular properties. They were also utilized to draw attention to archway lines in the past. They’re more costly, but their architectural look is one of the most stylish you’ll find.


In the end, we conclude that the weight of a brick depends on its specifications. The standard brick size is 92 mm x 57 mm x 203 mm. The weight of a brick is between three to five pounds.

The number of bricks required to make a wall depends on the size of the wall. Selecting the right kind of brick is important and it is best to consult a masonry professional.

Also, don’t forget to take the mortar into account when calculating the size of your wall.


How many kg is a brick?

A brick weighs between three and five pounds. To convert a brick’s weight in kilograms to pounds, multiply it by 2.204. Hence, the brick weight is around 6.612-11.02 kg.

What is the density of a brick?

The density of red brick is 1922 kg/m3.
