How Are Masonry Walls Measured
Masonry walls are measured by considering their length, width, and height, typically in meters or feet.
The thickness of the wall is also measured, along with the type of joint and joint filler material used.
Different types of mortar or mortar with admixtures are measured in terms of volume.
If there is any reinforcement in the wall, it is measured separately.
Extra items like anchor bolts and brackets are described and measured separately as well.
The presence of weep holes and plastic inserts is noted.
Rigid insulation is measured in square feet or square meters, specifying the type and thickness of the material.
Specific rules are provided for measuring brick and concrete block masonry.
Reinforced concrete and reinforced brickwork are measured in cubic meters, excluding steel reinforcement but including centering and shuttering.
The volume of steel reinforcement is calculated separately.
Base concrete and floor finishing are usually combined and measured in square meters.
Lime concrete terracing has a compacted thickness of 7.5 cm to 12 cm.
Plastering is typically 12mm thick and measured in square meters.
The entire face of the wall is measured on both sides, with deductions made for openings.
Pointing and ornamental features are calculated in square meters or running meters, depending on the item.
Pillars are measured separately in cubic meters, while wooden beams and posts are calculated based on finished dimensions.
The weight of these items is computed in kg or quintal, and quantities are determined by multiplying the weights per running meter by the length.
Inside surfaces are calculated in the same way as outside plaster, taking into account factors like whitewashing or distempering.
Did You Know?
1. The thickness of masonry walls is often measured in a unit called “wythe,” which refers to a single vertical stack of bricks or blocks.
2. In ancient civil engineering, the height of masonry walls was determined by the length of a person’s arm. This measurement method was called “cubit” and varied between civilizations, approximately measuring 18 inches to 21 inches.
3. Masonry walls can be measured according to their “bond,” which refers to the pattern in which bricks or stone units are laid. Common bond patterns include stretcher bond, header bond, and Flemish bond.
4. The length of masonry walls is sometimes measured in a unit known as “perch.” One perch is equal to 16.5 feet, historically based on the amount of stone that masons could lay in a day.
5. Masonry walls are often evaluated for their “plumbness,” which refers to their vertical alignment. The ancient Roman architect Vitruvius recommended a maximum deviation of only 1/30th of the wall’s height to ensure structural stability.
Length, Width, And Height Measurements
When it comes to measuring masonry walls, accurate measurements of the length, width, and height are essential in the construction process. These measurements are typically recorded in either meters or feet, depending on the preference or standards of the project. The precise dimensions of the walls ensure that they fit properly and meet the necessary specifications.
The length measurement refers to the horizontal extension of the wall, while the width measurement represents the vertical span. The height measurement pertains to the distance from the base of the wall to the top. These measurements are crucial in:
- determining the amount of materials needed,
- estimating costs, and
- planning the overall structure.

Thickness Of Masonry Walls
In addition to the length, width, and height, the thickness of masonry walls is an important factor to consider. The thickness measurement determines the strength, durability, and insulation properties of the wall. It is typically expressed in units of inches or centimeters, depending on the region or project specifications.
The thickness of a masonry wall can vary depending on the type of construction and the intended purpose of the wall. For example, load-bearing walls usually require greater thickness to support the weight overhead. On the other hand, non-load-bearing walls may have a thinner profile.
By accurately measuring the thickness, builders can ensure structural integrity and compliance with building codes.

Description Of Joints And Filler Material
When measuring masonry walls, describing and documenting the type of joint and filler material used is crucial. Joints, which are the gaps between masonry units, have multiple functions. They distribute loads, accommodate expansion and contraction, and prevent water penetration.
The type of joint used, whether it’s a butt joint, raked joint, or concave joint, significantly impacts the wall’s structural strength and overall appearance. Similarly, the filler material, such as mortar or specialized joint sealants, provides stability and seals the joints against moisture infiltration.
Precisely identifying and measuring the joints and filler material ensures that the appropriate materials are selected and installed correctly. This guarantees the longevity and performance of the masonry wall.
Measurement Of Mortar Or Mortar With Admixtures
In the measurement of masonry walls, particular attention must be given to the mortar or mortar with admixtures used. Mortar is the binding material that holds the individual masonry units together and provides strength and stability to the wall.
The volume of mortar required for a masonry wall is typically measured in cubic meters or cubic feet. Proper measurement of mortar ensures that the correct amount is prepared, minimizing waste and ensuring the structural integrity of the wall.
In cases where mortar admixtures, such as lime or acrylic additives, are used to enhance the properties of the mortar, these too are measured separately. Accurately quantifying the volume of mortar and any admixtures is crucial for estimating material costs and achieving the desired strength and durability of the masonry wall construction.
Reinforcement And Extra Items In Masonry Walls
In addition to the masonry units and mortar, it is important to measure other elements incorporated into masonry walls separately. Reinforcement materials, such as steel bars or mesh, provide added strength and stability to the wall, especially in areas where increased load-bearing capacity is needed. Accurate measurement of the quantity of reinforcement materials ensures proper distribution and positioning within the wall.
Additional items like anchor bolts, sleeves, and brackets are also measured separately to ensure accurate planning, installation, and cost estimation. These elements are vital in securing attachments, supporting loads, and enhancing the functionality of the masonry wall.
By meticulously measuring and documenting the reinforcement and extra items in masonry walls, builders can ensure that the structure is well-designed, safe, and capable of withstanding the expected loads and environmental conditions.

Frequently Asked Questions
How is masonry measured?
Masonry works are primarily measured based on volume, which includes brick masonry, concrete block, stone, or rubble masonry. However, if the thickness of the masonry is limited to a single brick or single block, it can also be measured in terms of area. On the other hand, tiling is specifically measured in terms of area. These different measurement methods allow for accurate and efficient quantification of masonry and tiling projects, ensuring proper planning and execution.
What is the unit of measurement of brick masonry?
The unit of measurement for brick masonry is typically cubic meters (m3). This is commonly used to quantify the volume of brickwork. However, when it comes to measuring one-brick-thick walls or walls of lesser thickness, the unit of measurement shifts to square meters (m2). In this case, it is crucial to mention the exact thickness of the item being measured, allowing for a more precise assessment of the brickwork area.
Which method of measurement used for calculating materials needed for masonry walls?
One method commonly used for calculating materials needed for masonry walls is the crossing method. This approach involves taking into account the lengths and breadths of walls at the plinth level, which serves as the foundation for a column. By including these measurements, a more accurate estimate of the materials required for constructing the masonry walls can be determined. This method offers a reliable and systematic way to calculate the necessary quantities, ensuring efficient and precise planning for masonry projects.
What are the measurements of blockwork?
Blockwork measurements can vary depending on the specific requirements of a project. Generally, a standard block has dimensions of 440 mm x 215 mm, which makes it 3 bricks high and 2 long. This size is designed to be easily lifted by one person without strain. However, blockwork is available in a range of widths, spanning from 50 mm to 300 mm. The selection of a specific block will depend on its density, which is determined by the intended application.
