Brick Bonds: Types, Uses and How to Choose
Compare running, stack, English, Flemish and decorative layouts using a three-step check of visible geometry, wall system and required detailing.
A brick bond is the repeating arrangement and overlap of masonry units. To choose one sensibly, separate three questions: What geometry is visible? What wall system sits behind it? What ties, reinforcement, supports, and movement details does that system require?
Running bond staggers vertical head joints; stack bond aligns them. That distinction helps identify the pattern, but the bond name alone does not establish structural capacity. The complete wall assembly—not its face pattern—determines how loads are carried and how moisture, movement, openings, and lateral support are handled.
Brick bonds at a glance
In technical usage, bond can describe the pattern formed by exposed unit faces, the overlapping or tying together of wall components, or adhesion among units, mortar, grout, and reinforcement. A brick bond pattern usually means the first of these: how bricks and joints repeat across the wall. The Brick Industry Association’s masonry terminology distinguishes running bond, with offset head joints, from stack bond, with aligned head joints.
Running or stretcher bond is the easiest reference point. Its vertical head joints shift horizontally from one course to the next. Stack bond does the opposite: its head joints form straight vertical lines. Staggering provides conventional unit overlap, but visible overlap alone does not define the wall system or verify its capacity.
| Pattern or treatment | Repeating layout | Visual cue | Customary context and key limitation |
|---|---|---|---|
| Running or stretcher | Stretcher courses with offset head joints | Long faces and staggered joints | Straightforward facing and general wall layouts; visible overlap does not define the complete wall |
| Header | Courses composed of headers, normally offset | Repeated short faces | Traditional multi-wythe or radial work; modern visible headers may not cross the wall |
| English | Alternating complete stretcher and header courses | Horizontal bands of long and short faces | Traditional solid or multi-wythe work; corners and internal bonding require separate details |
| Flemish | Alternating stretcher and header within each course | Checker-like rhythm | Traditional façades and solid walls; careful setting-out and additional cuts may be needed |
| Common | Several stretcher courses interrupted by a header course | Mostly running bond with occasional header bands | Traditional multi-wythe work; the header-course interval is not universal |
| English Garden Wall | Usually three stretcher courses followed by one header course | Widely spaced header bands | Traditional wall geometry; fewer header courses alter transverse bonding |
| Flemish Garden Wall | Three stretchers followed by one header within each course | Sparse headers in every course | Also called Sussex bond in UK guidance; appearance does not verify construction |
| Monk | Two stretchers followed by one header within each course | More frequent headers than Flemish Garden Wall | Decorative traditional geometry; corners and closures need planning |
| Stack | Head joints aligned through successive courses | Strong vertical grid | Architectural panels and façades; requires project-specific structural detailing |
| Soldier | Bricks stood on end in a course | Tall, narrow faces | Bands, wall tops, and openings; an orientation or course treatment, not a complete wall bond |
| Wild | Deliberately irregular-looking distribution | Apparently random joints or headers | Textured façades; the intended arrangement still needs coordinated setting-out |
| Herringbone | Bricks laid diagonally in opposing directions | Zigzag or chevron | Ornamental panels and paving-like fields; not equivalent to conventional running-bond walling |
Wall-design note: Assess wall type, loads, thickness, mortar, ties, reinforcement, supports, openings, exposure, movement accommodation, drainage, and workmanship separately. A façade pattern may conceal a cavity wall, veneer, solid wall, reinforced wall, or nonstructural panel.
The terms used to read a bond pattern
A stretcher is a brick laid so that its long side is displayed on the wall face. A header displays the short end. These terms identify the visible face; they do not prove how far the unit extends behind it.
A course is a continuous horizontal layer of masonry. The horizontal mortar joint above or below a course is a bed joint. A head joint is the vertical mortar joint between units within a wythe; in UK usage, it may also be called a perpend.
A wythe is a continuous vertical section of masonry one unit thick. It is a wall component, not necessarily the complete assembly. A wall can have one wythe or several; a cavity wall has separated leaves or wythes with a cavity and potentially other materials between them.
Traditionally, a header or bonder could extend through adjoining wythes and connect them. A wall tie is different: it is a separate connector joining wythes. These definitions appear in the 2000 International Building Code masonry chapter, but that historical edition must not be treated as the current governing code for a project.

A soldier stands on end with its narrow face visible. A sailor also stands on end but presents a broader face. A rowlock lies on its edge with an end or narrow face exposed, while a rowlock-stretcher lies on edge with the longer broad face displayed. These are orientations. They become part of a bond only when arranged into a defined repeat.

Running, stack, and header bonds
Running bond consists of successive courses whose head joints are offset. A half-unit offset is common, but the technical definition is broader: running bond has head joints horizontally offset by at least one-quarter of the unit length in successive courses, according to the BIA terminology cited above.

Other offsets can still qualify as running bond when they provide the applicable overlap and are incorporated into a complete wall design.

Because stack bond lacks conventional running-bond overlap, it requires reinforcement or other structural detailing under the applicable design requirements; the BIA glossary specifically notes a bed-joint reinforcement requirement under the applicable code. Reinforcement spacing cannot be selected from the pattern name alone. Loads, wall type, supports, anchorage, movement, unit properties, and current locally adopted requirements all affect the design.
Header bond turns the bricks so that their short faces appear across the course:

The shorter exposed face can help header bond accommodate tighter radial work, according to Wienerberger UK’s bond-pattern guide. Radius, tapering joints, cuts, wall thickness, backing, and structural support still require project-specific coordination.
English, Flemish, and their garden-wall variants
English bond alternates complete courses of stretchers and headers:

UK supplier guides describe English bond as stronger than Flemish bond in traditional solid, one-brick-thick, or multi-wythe configurations. This is not a universal strength ranking: the supplied guidance does not provide controlled comparisons covering all units, mortars, wall thicknesses, loads, reinforcement, and workmanship. A modern veneer displaying Flemish geometry is also a different wall system from a traditionally bonded solid wall.
English Garden Wall bond reduces the frequency of header courses:

repeat after three stretcher courses
Caption: Whole-wall field repeat showing the usual three-stretcher-course sequence before a header course.
Three stretcher courses followed by one header course is the usual definition in the cited UK guidance. A variation with five stretcher courses before the header course is also reported, so the intended repeat should be drawn rather than assumed.
Flemish Garden Wall bond—also called Sussex bond in UK-oriented sources—uses three stretchers followed by one header within each course. Monk bond uses two stretchers followed by one header:

These sequences and the five-stretcher-course English Garden Wall variation are described in Imperial Bricks’ UK pattern guide. It does not, by itself, determine whether a modern wall is structurally adequate.
Common, wild, soldier, and herringbone patterns
Common bond consists mainly of stretcher courses interrupted by periodic header courses. Glen-Gery’s brick bond pattern sheet shows a header course every five or six courses, but that is a published convention rather than a universal interval.

Wild bond is arranged to look irregular. Headers, joints, colours, or unit positions may appear random, but “wild” describes the visual effect rather than a structural rating. The project designer and mason must still establish a buildable layout and coordinate the field with ends, corners, and openings.

Traditional solid walls versus modern cavity walls
In traditional solid or multi-wythe masonry, full headers could extend into or across adjoining wythes. Their physical overlap helped bond the wall through its thickness.
A modern cavity wall works differently. Its outer and inner leaves are separated by a cavity and are generally connected using wall ties. Cavity continuity forms part of the assembly’s moisture-management approach, so full bricks should not be inserted casually across it merely to reproduce a traditional pattern.

Caption: Conceptual comparison only. Ties, cavities, flashing, drainage, insulation, clearances, and attachment details are not shown to scale.
A cavity-wall façade can reproduce English or Flemish geometry with bats, snapped headers, or other specified header-look units rather than full bricks crossing the cavity. UK guidance specifically recommends simulated or snapped headers to avoid bridging the cavity. The appropriate unit and attachment detail depend on the actual wall specification.
Most importantly, a visible header does not prove that the brick connects two wythes. Read the wall section before interpreting the elevation: first identify whether the construction is solid, multi-wythe, cavity, veneer, or another assembly; then determine what the visible header is doing.
Choose the offset from brick proportions and wall layout
The most convenient running-bond offset often follows the unit’s proportions. If nominal brick length is approximately twice nominal width, a half-unit offset commonly coordinates at corners. If nominal length is approximately three times nominal width, a one-third-unit offset may reduce awkward cuts.
Consider two proportional examples:
- Unit A: Nominal length is approximately two times nominal width. A half-unit offset is approximately one width, allowing adjacent faces at a square corner to coordinate naturally.
- Unit B: Nominal length is approximately three times nominal width. A one-third-unit offset is approximately one width. A half-unit offset does not match the width as cleanly and may create additional cuts at returns, ends, or jambs.
The effect becomes apparent where the repeating field reaches an end condition. At corners, openings, piers, returns, and window jambs, an unsuitable offset can leave small pieces or force a revised joint sequence. Draw at least two courses around these conditions before fixing the bond.
In North American modular guidance:
- Nominal dimensions include the intended mortar allowance.
- Specified dimensions are the intended manufactured unit dimensions, excluding mortar.
- Actual dimensions are measurements of manufactured units and also exclude mortar.
The BIA technical note on brick dimensioning and estimating recommends half-running bond where brick width is approximately half its length and one-third running bond where width is approximately one-third its length. It also recommends specifying brick by width × height × length rather than relying only on regional size names.
That guidance is North American and uses modular coordination and ASTM-based terminology. It should not be applied automatically to UK brick sizes, mortar conventions, or construction practice. In any market, confirm the manufacturer’s specified dimensions, intended joint thickness, dimensional tolerances, available corner units, and proposed setting-out before completing the layout.
A practical bond-selection and estimating checklist
Start with the wall assembly, not a photograph of the desired pattern.
| Wall or design objective | Suitable direction | Cutting and labour implications | Engineering input |
|---|---|---|---|
| Typical cavity-wall facing | Running bond is generally straightforward; ties and the complete assembly perform functions the face pattern does not | Regular repeat and usually fewer special cuts | Required where wall height, loading, support, code, or unusual geometry warrants it |
| Traditional solid-wall appearance | Compare English, Flemish, and garden-wall geometry, then specify the actual wall construction | Headers, closures, corners, and setting-out can increase complexity | Required for load-bearing or otherwise structural walls |
| Decorative aligned-joint panel | Consider stack bond only with coordinated reinforcement, anchorage, support, and movement details | Precise alignment and additional components affect labour | Project-specific review is essential |
| Curved or radial work | Header bond may help because the exposed face is shorter | Tapered joints, cuts, radius, and backing need coordination | Curvature and support remain project-specific |
| Brick length about twice its width | Consider half-running bond | Can coordinate corners and reduce unnecessary cutting | Review if structural assumptions or required overlap change |
| Brick length about three times its width | Consider one-third running bond | May reduce cuts at ends, returns, and jambs | Review if structural assumptions or required overlap change |
| Ornamental band or panel | Use soldier or herringbone as a defined treatment within the wall design | Borders, cutting, support, and water shedding need detailing | Needed where the treatment crosses openings or affects support |
Bond selection can change skilled-labour requirements, partial units, cuts, breakage, waste, mortar quantities, corner construction, and treatment around openings. Flemish and header-rich patterns may require more careful setting-out and cutting than a simple running-bond field, but no reliable universal percentage describes the cost difference. Brick dimensions, façade complexity, labour conditions, scaffolding, detailing, and project scale all matter.
For estimating, record:
- net and gross wall area;
- manufacturer-specific brick width, height, and length;
- intended bed-joint and head-joint thicknesses;
- the complete bond repeat;
- brick count within each repeating module;
- partial units and closures at corners, returns, piers, and openings;
- cuts at sills, jambs, heads, and wall ends;
- special shapes, bats, or header-look units;
- breakage and a project-appropriate waste allowance;
- mortar volume as affected by unit size and bond;
- collar joints in solid or multi-wythe work, where applicable;
- changes in bond at bands, arches, soldiers, or ornamental panels.
Finish the selection with a three-step check:
- Identify the repeating geometry: stretcher and header faces, course sequence, joint offset, and special orientations.
- Identify the wall system behind the face: solid, multi-wythe, cavity, veneer, reinforced wall, or decorative panel.
- Verify dimensions and structural detailing: ties, reinforcement, anchorage, supports, openings, drainage, movement accommodation, and current locally adopted requirements.
Load-bearing walls, tall walls, stack or aligned joints, reinforced masonry, seismic design conditions, curved walls, unusual openings, and questions about current code requirements should be referred to the responsible architect or structural engineer. Running, English, Flemish, garden-wall, and decorative patterns can be recognized visually; their load-bearing capacity and compliance can be determined only from the complete wall design.
