Enter Your Wall Dimensions

Measure the full length of the wall face to be bricked. Please enter a valid length greater than 0.
Full height from base to top of wall. Please enter a valid height greater than 0.
Standard and Modular are the most common in US residential construction.
⅜ inch (10 mm) is the standard joint for most brickwork. Smaller joints are used for thin-set or specialty work.
10% is standard. Use 15% for complex angles, arches, or first-time installers. Never go below 5%.
$
US average: $0.50–$1.50 per standard brick. Specialty or face brick: $1.50–$5.00.

Type S mortar (standard exterior) runs $10–$18 per 60 lb bag at hardware stores.

Step 1: Wall area (ft²) = Length (ft) × Height (ft)
Step 2: Course height (in) = Brick face height + Mortar joint
Step 3: Brick unit width (in) = Brick face width + Mortar joint
Step 4: Bricks per ft² = (12 ÷ course height) × (12 ÷ unit width)
Step 5: Net bricks = Wall area (ft²) × Bricks per ft²
Step 6: Total bricks = CEIL(Net bricks × (1 + waste% ÷ 100))
Step 7: Mortar vol (ft³) ≈ Wall area × joint thickness × 1.5 (joint factor)
Step 8: Mortar bags = CEIL(Mortar ft³ ÷ bag yield)

Mortar bag yields: 60 lb = 0.45 ft³ | 80 lb = 0.60 ft³

How to Use This Brick Calculator

  1. Measure your wall length and height. Use a tape measure to get the full length and height of the area to be bricked. For walls with openings (windows, doors), subtract those areas after calculating — enter the full wall dimensions first, then deduct the opening areas by running a second calculation and subtracting. Measure to the nearest inch; small errors compound into significant brick count differences on long walls.
  2. Select your brick size and mortar joint. Pick the brick type your supplier stocks — Standard and Modular are the most common in US residential work. Confirm the mortar joint with your mason: ⅜ inch is the industry default for most applications. Specialty work (thin brick veneer, restoration) may use ¼ inch or even ⅛ inch joints, which significantly increases brick count per square foot.
  3. Set a realistic waste factor. 10% covers most straight-run walls with minimal cuts. Bump to 15% for walls with corners, curves, or arches, where a large number of bricks will be cut to fit. Never order exactly the net count — bricks can arrive chipped from delivery, and reordering a small quantity mid-job typically costs a delivery premium and causes delays.
  4. Use the results to order materials. Give the brick count directly to your supplier. Order mortar bags based on the bag count shown — Type S mortar is standard for exterior and structural work; Type N for interior non-load-bearing veneers. If you entered pricing, the cost estimate shows your material-only budget. Always confirm with your supplier, as brick prices vary significantly by region and brick type.

⚠ Pro Tip: Always buy all your bricks from a single production run. Brick color and texture vary between kiln firings — even from the same manufacturer. If you run short and order a second batch, the new bricks will likely be visibly different from the first, which is obvious on any wall face. Order 10–15% extra upfront and return the sealed pallets; most suppliers will accept returns on unopened stock.

Brick Calculation Formula Explained

The calculation works from the face dimensions of the brick plus the mortar joint to determine how many bricks fill one square foot, then scales to the full wall area.

Step Formula Example (Standard brick, ⅜ in joint)
1. Course height (in)Brick height + Joint2.25 + 0.375 = 2.625 in
2. Unit width (in)Brick width + Joint8 + 0.375 = 8.375 in
3. Bricks per ft²(12 ÷ course height) × (12 ÷ unit width)(12 ÷ 2.625) × (12 ÷ 8.375) = 6.56 bricks/ft²
4. Net bricksWall area (ft²) × Bricks per ft²160 ft² × 6.56 = 1,050 bricks
5. With 10% wasteNet × 1.101,050 × 1.10 = 1,155 bricks

Which Brick Size Should You Use?

Brick size is one of the first decisions you make on a masonry job, and getting it wrong wastes money and creates visual problems you can't fix without tearing down the wall. The table below shows the most common US brick types, their actual face dimensions, and the applications each is best suited for.

Common US brick sizes, face dimensions, and application guidance. All nominal dimensions include a standard ⅜ in mortar joint.
Brick Type Face Dimensions (W × H) Bricks / ft² Best For
Standard8 × 2¼ in6.56General residential; most common material everywhere
Modular7⅝ × 2¼ in6.86Where coursing must align with 8-inch CMU block
Engineer Modular7⅝ × 2¾ in5.76Faster lay rate, fewer mortar joints, good for tall walls
Norman11⅝ × 2¼ in4.57Long horizontal lines, contemporary exteriors, accent bands
Queen9⅝ × 2¾ in4.78Popular in Southeast US; slightly larger scale than standard
Jumbo Standard8 × 2¾ in5.37Faster installation; same length as standard but taller course
Thin Brick Veneer7⅝ × 2¼ in (½ in depth)6.86Interior accent walls, fireplace surrounds, tile-over applications

If you are tying a new brick wall to an existing CMU (concrete block) structure, use Modular brick — its nominal dimensions are designed to course evenly with 8-inch CMU every 3 courses. Standard brick does not course evenly with CMU, which forces awkward joint size adjustments or a soldier course to compensate.
