Brick Wall Calculator
Estimate the number of bricks and mortar needed for a wall.
Use decimals when needed. This estimate updates live and is safe to tweak before you buy materials.
Brick Wall Buying Guide
This guide helps you turn your brick wall calculator result into a cleaner purchase plan. Use it when you want fewer return trips, better waste assumptions, and a more realistic cart.
Step 1: Determine the brick size
Standard modular bricks require about 7 bricks per square foot. Larger 'engineer' or 'closure' bricks cover more area, requiring fewer bricks and less mortar.
Step 2: Factor in the mortar joint
The standard mortar joint is 3/8 inch thick. Your brick count estimate assumes this joint thickness. Thinner joints will require more bricks.
Step 3: Add a high waste factor
Bricks chip during shipping, and you will have to cut many bricks in half to stagger the joints at corners. Always add at least 5-10% waste.

Brick wall cost planning rule of thumb
A brick wall requires the bricks, Type N or Type S mortar mix, masonry sand, corrugated wall ties, and a sturdy concrete footing.
Understanding the Math
Formula: The basic formula for Brick Wall Calculator typically involves calculating the total area or volume (Length × Width × Depth) and dividing by the coverage of a single unit or package, then adding a waste factor (usually 10%).
Example: For example, if you have a 10x10 area and your material covers 10 square feet per unit, you need 10 units. With a 10% waste factor, you should purchase 11 units to ensure you don't run short.

Brick Wall Calculator FAQ
Do I need to include the mortar joint size?
Yes, including the mortar joint size is crucial. A standard 3/8-inch joint adds up over a large wall and significantly reduces the total brick count.
How much extra brick should I order?
It's standard practice to add 5% to 10% extra for waste, cuts, and breakage during transport.
