Count bricks from your wall, brick size and joint width. Small changes in joint width move the total by hundreds on a house wall.

How it works

One brick covers its length plus joint × height plus joint. Divide 144 by that for bricks per square foot, then multiply by net wall area with 5% added.

Before you order

  • Measure a sample brick, since names like standard vary by plant.
  • Mix from several pallets as you lay so color shifts blend across the wall.
  • Lay out window and door openings to whole bricks where you can.

Common questions

How many bricks per square foot?

About 6.9 for a modular brick with a 3/8 inch joint, and roughly 6.5 for a standard 8 inch brick.

Should I use a wider joint?

Stick with 3/8 inch unless the design calls for something else. Wider joints use more mortar and change coursing.
