Brick Calculator for a Single-Wythe Wall Face
Estimate bricks for one layer of a wall face using its length, height and openings. Enter brick face dimensions without joints, then a uniform joint thickness and your chosen allowance. This is an approximate area estimate, not a course or cut layout.
Starting figures illustrate the calculation. Replace them with verified measurements and the actual product details. Allowances are your choice, not a recommended rate.

Approximate face-area method with uniform entered joints. One wythe only. It does not lay out courses, corners, bonds, cuts, ties, foundations or structural requirements. Specified brick dimensions and the project layout control the actual order.

Use the brick dimensions and joints you intend
Net wall face area = length × height - opening area. In this area model, bricks per square foot = 144 / ((brick length in inches + joint) × (brick height in inches + joint)). Multiply by net area and round up for the base count.
The extra allowance is applied to the unrounded area-model count, then the total is rounded up to whole bricks. With 100 sq ft, 7.625-inch by 2.25-inch faces and 0.375-inch joints, the model gives about 685.714 bricks: 686 before allowance or 755 with a chosen 10% allowance.
BIA distinguishes nominal, specified and actual brick dimensions. The starting face dimensions illustrate a modular brick, but the project specification and supplier details control your inputs. Joint choice and actual coursing can change the takeoff.
One face-area calculation is not the complete wall
One wythe means one layer through the wall thickness. This tool does not multiply layers or count corner returns, special shapes, bond patterns, cuts, piers, caps, reinforcement or structural parts. Check these separately in the actual project layout.
Subtract measured openings only once and choose an allowance appropriate to your order. A percentage is not a substitute for planning cuts and special units. The result does not select a brick or certify a wall assembly.
