How many square feet does 1000 bricks cover?

Determining how many square feet 1000 bricks will cover requires some simple calculations based on the size of the bricks. Brick sizes can vary, but standard bricks are about 8 inches long by 2-1/4 inches high by 3-3/4 inches wide. Knowing the dimensions of the bricks along with the number of bricks allows us to calculate the total square footage covered. We’ll walk through the steps to find the answer below.

Brick Dimensions

As mentioned above, standard brick sizes are approximately:

– 8 inches long
– 2-1/4 inches high
– 3-3/4 inches wide

These are the key measurements we’ll need to determine the coverage area.


With brick dimensions in hand, we can now calculate the coverage area:

– Each brick is 8 inches long
– If bricks are laid end to end, 12 bricks laid lengthwise will cover 8 * 12 = 96 inches
– 96 inches is equivalent to 8 feet
– So 12 bricks laid lengthwise will cover 8 feet

– Each brick is 3-3/4 inches wide
– If bricks are laid side by side, 21 bricks laid widthwise will cover 3.75 * 21 = 78.75 inches
– 78.75 inches is equivalent to 6 feet 6 inches
– So 21 bricks laid widthwise will cover 6 feet 6 inches

– To find the total coverage area, we multiply the lengthwise coverage by the widthwise coverage:
– 12 bricks laid lengthwise covers 8 feet
– 21 bricks laid widthwise covers 6 feet 6 inches or 6.5 feet
– So 12 * 6.5 = 78 square feet
– That’s the coverage for 1 row of bricks

– With 1000 bricks we can calculate rows:
– Each row takes 12 * 21 = 252 bricks
– So 1000 bricks will make 1000/252 = 3.97 rows.
– Rounding down, 1000 bricks will make 3 full rows.

– Finally, with 3 rows of 78 square feet each, the total coverage is:
– 3 rows * 78 square feet per row = 234 square feet

So in total, 1000 standard size bricks will cover approximately 234 square feet.

What If Brick Size Changes?

The above calculation assumes standard brick sizes. But what if the bricks are a different size?

If the brick length or width changes, the coverage area for 1000 bricks would also change.

For example, say the bricks were 9 inches long instead of 8 inches. Following the same calculations:

– 9 * 12 = 108 inches or 9 feet per row lengthwise
– 21 bricks is still 6.5 feet widthwise
– So each row would cover 9 * 6.5 = 58.5 square feet
– 1000 bricks would make 3 full rows
– 3 rows * 58.5 square feet per row = 175.5 square feet

For this slightly longer brick, 1000 bricks would cover about 175.5 square feet instead of 234 square feet.

So if you know the dimensions of the bricks you are working with, you can adjust the calculations accordingly. The steps remain the same – you just plug in the different length and width measurements.

Usage Guidelines

Knowing the coverage area for a certain number of bricks is useful for a few reasons:

Estimating Materials for a Project

If you’re planning a brick patio, walkway, or other project, you can calculate the approximate number of bricks needed based on the total square footage you want to cover. This helps with purchasing the right quantity of materials.

Validating Contractor Estimates

Contractors will provide brick estimates for projects too. Having your own brick coverage estimate allows you to validate the accuracy of their quote based on the dimensions being used.

Comparing Brick Options

When deciding between different brick types and sizes, calculating the coverage for each option helps compare costs. A brick with a different shape or dimensions may cover more or less area per brick.

So being able to calculate brick coverage yourself gives you more control over project planning and decision making.

Factors that Influence Coverage

While the above calculations provide a good general estimate, there are a few other factors that can influence the actual coverage area of bricks:

Mortar Joints

Mortar joints between bricks take up space, so the coverage calculations don’t account for those gaps. With typical mortar joint thickness, this can reduce the coverage estimate by 5-10%.

Brick Patterns

The pattern in which bricks are laid (running bond, herringbone, basketweave, etc) can alter coverage due to differences in spacing between bricks. Simple grid patterns like running bond provide the maximum coverage.


When doing an actual project, there will inevitably be some wasted bricks due to cuts, breakage, and irregular spaces. Ordering 5-10% extra bricks allows for waste during installation.

So your exact project needs may require tweaking the estimated coverage area. But the calculations here provide a useful starting point for planning purposes.

Determining brick coverage area is a matter of multiplying the length and width coverage of each row, then accounting for the number of rows based on total bricks.

For a standard brick size of 8″ x 3.75″ x 2.25″, 1000 bricks will cover approximately 234 square feet laid in 3 rows.

If your bricks are a different size, simply adjust the length and width values used in the calculations. Coverage will vary based on the different dimensions.

To account for mortar and waste, add 5-10% to your total brick quantity estimate.
