The most commonly used types of bonds in brick masonry are:

- Stretcher bond

- Header bond

- English bond and

- Flemish bond

English bond in brick masonry has one course of stretcher only and a course of header above it, i.e. it has two alternating courses of stretchers and headers. Headers are laid cantered on the stretchers in course below and each alternate row is vertically aligned.

Flemish bond, also known as Dutch bond, is created by laying alternate headers and stretchers in a single course. The next course of brick is laid such that header lies in the middle of the stretcher in the course below, i.e. the alternate headers of each course are centered on the stretcher of course below. Every alternate course of Flemish bond starts with header at the corner.

Flemish bonds are classified as:

- Single Flemish Bond

- Double Flemish Bond

Header bond is also known as heading bond. In header bonds, all bricks in each course are placed as headers on the faces of the walls.

Stretcher bond is also called as running bond, is created when bricks are laid with only their stretchers showing, overlapping midway with the courses of bricks below and above.
