How this calculator works
It calculates your wall area and multiplies by about 7 bricks per square foot — the standard for modular bricks with a 3/8-inch mortar joint — then adds 5% for cuts and breakage.
Worked example — a 20 ft × 8 ft wall:
160 sq ft × 7 × 1.05 = 1,176 bricks.
Single vs. double layer
This assumes a single-brick (veneer) face. A double-thickness structural wall needs roughly twice as many bricks.
Frequently asked questions
How many bricks per square foot?
About 7 modular bricks per square foot of wall with standard mortar joints.
How much extra should I order?
Add 5% for breakage and cuts; keep a few spares for future repairs.
Planning a concrete or masonry project
Material estimates are only one part of a masonry job. Check the product yield on the bag or supplier quote, allow for the shape of the site, and confirm delivery minimums before ordering. For structural work, follow local building requirements and get advice from a qualified professional.
How to use this estimate
- Measure the project in the units shown and recheck your measurements before ordering.
- Use the waste allowance as a planning buffer, not as a substitute for a detailed material takeoff.
- Compare the result with the package yield, coverage, or weight listed by your supplier.
- Prices are user-entered estimates and may change by location, product, delivery, and season.
Accuracy and limitations
Calculapedia provides educational planning estimates. It does not inspect your site, select products, guarantee quantities, or replace a contractor, engineer, architect, building official, or supplier. Confirm the final quantity and any safety or code requirements before buying or building.
