How many bricks you need
Brick count is bricks = ceil(wall area × bricks per square foot). Standard modular brick lays about 7 per sq ft including mortar joints, so 100 sq ft needs 700 bricks. Wall area comes from the square footage calculator if you have not measured it yet.
How to use this calculator
Enter the wall area in square feet and the bricks per square foot for your brick size. The result rounds up. For a poured footing under the wall, size it with the concrete calculator.
Measure each wall separately and add the areas together for a full elevation. Mortar needs sand, which the sand calculator can quantify.
Brick sizes and waste
Modular brick is about 7 per sq ft; queen and king sizes use fewer. Add about 5–10% for cuts and breakage. Interior walls may use drywall instead — see the drywall calculator.
Bricks are fired in batches and colour varies noticeably between them, so buy the whole job at once from a single lot and keep a few dozen spares for later repairs. Ordering by the pallet is usually cheaper than buying loose: a pallet of modular brick holds roughly 500 units. The area you enter should be the finished face area of brickwork, so subtract large window and door openings, but do not subtract the mortar joints themselves, because the seven-per-square-foot figure already includes them. Order a full pallet rather than a part load if the wall is close to the next pallet up.
Frequently asked questions
- How do I calculate bricks?
- Multiply the wall area in square feet by the bricks per square foot, then round up.
- How many bricks per square foot?
- Standard modular brick is about 7 per sq ft including mortar joints; larger bricks use fewer.
- Should I order extra bricks?
- Yes, about 5–10% for cuts, breakage and future repairs from the same batch.
- Does the count include mortar joints?
- Yes — the 7-per-sq-ft figure already accounts for standard mortar joint thickness.
- How much mortar do I need?
- Plan on roughly seven bags of mortar mix per 1,000 modular bricks with standard 3/8-inch joints. Wider joints, rough bricks and cold weather all push that figure up, so keep a spare bag on site.
