The nominal size of an Indian brick is 200 mm x 100 mm x 100 mm, the actual size is 190 mm x 90 mm x 90 mm, and the standard size is also 190 mm x 90 mm x 90 mm. The difference between nominal and actual size accounts for the mortar thickness used in bricklaying.
In this article we know about what is the standard size of Indian brick? | brick size | standard brick size | nominal brick size, various countries have various standard brick size and dimensions, however, brick can be made in multiple shapes and sizes, depending on its application Fan manufacturer.
If bricks are large, it is difficult to burn them properly and they become too heavy to be placed with a single hand, on the other hand, if bricks are small, more quantity of mortar is required, hence, a standard dimension is determined for various brick works.
Brick size
Brick size may vary according to different standard, in India, standard size of brick is 8″ × 4″ × 4″ (200mm × 100mm × 100mm) including 10mm mortar thickness in respect to their length, width and depth.

Actual size of brick/ nominal size of brick
Actual size (or the specified size) of brick is the real dimension of the brick without mortar thickness such as actual size of modular brick is 190mm× 90mm× 90mm.
Nominal size is the actual size plus the width of the mortar joint, taking mortar thickness 10mm, so nominal size of modular brick is 190mm× 90mm× 90mm (8″×4″×4″). Most bricks are manufactured in such a way that the nominal sizes fit into a grid of 4 inch, which comply with the modules of other building materials such as doors, windows, and wood components.
Standard & Nominal Brick size in India
There are two size of brick used in india standard brick and nominal brick size. The standard brick size is 190 mm x 90 mm x 90 mm as per the recommendation of BIS. With mortar thickness, the dimension of the brick becomes 200 mm x 100 mm x 100 mm which is also known as the nominal size of the modular brick.
Modular brick means brick along with cement mortar joints, standard modular brick size is 200mm ×100mm ×100mm, volume of one standard modular brick is 0.2m×0.1m×0.1m =0.002m3, so volume of one standard modular brick is 0.002m3.

Nominal size of brick– when we add thickness of brick joint or cement mortar thickness in actual size of brick that is nominal size of brick, such that nominal size of brick = Actual size of brick + thickness of cement mortar, actual size of modular brick is 190mm × 90mm × 90mm,when we add 10mm thickness in which dimension we get nominal size of brick in mm as 200mm × 100mm × 100mm, in cm as 20cm × 10cm × 10cm and in inches as 9″ × 4″ × 4″.
The common burnt clay bricks shall be classified on the basis of average compressive strength into different class designation like 35, 30, 25, 20, 17.5, 15, 12.5, 10, 7.5, 5 & 3.5 having compressive strength are 35 N/mm2, 30 N/mm2, 25 N/mm2, 20 N/mm2, 17.5 N/mm2, 15 N/mm2, 12.5 N/mm2, 10 N/mm2, 7.5 N/mm2, 5 N/mm2 and 3.5 N/mm2 respectively.
Standard brick size and weight
Standard brick size and weight: According to Indian practice the weight of standard size of brick is kept between 3- 3.5 kg, depending upon the class of brick, so that a mason can lift it by one hand and work full day. The width should be 4 to 5″ so that a mason can hold it using his fingers and thumb.
What is called frog in brick size?
An indent on one surface of longer side of brick is called Frog, the depth of Frog shall be 10–20 mm, and the size of shall be 10 X 40 X 10 cm. The purpose of providing frog is to hold the mortar. The side of frog is considered as Top surface. It is not provided in the 40 cm high bricks and extruded bricks.
But practically to match with the beam width a brick or block of width 230 mm is used widely in construction industry. The 115 mm is considered for half brick. The size 230 mm X 110 mm X 110 mm or 230 mm X 110 mm X 75 mm is generally used in construction industry.
Popular size of brick used in india
Modular/ Metric Brick: nominal size 20 x 10 x 10 cm. This size is common in MP and only some other places where machine made bricks are available.
English size: 23 x 11.5 x 7.5 cm or 9″ x 4.5″ x 3″ nominal size. This is the most popular size available in most parts of India.
Bengal size: 25 x 12.5 x 7.5 cm size or 10″ x 5″ x 3″. This size is popular in in West Bengal and some parts adjoining West Bengal and North East. A few other sizes are also used in some localized areas.
Basically the size of a brick is governed by its weight, which should not be more than 3 Kg, so that a mason can lift it by one hand and work full day. The width should be 4 to 5″ so that a mason can hold it using his fingers and thumb.
The ratios of length: breadth: thickness are so chosen that the bricks when laid in masonry make a pattern (or Bond) so that vertical joints do not come one above the other in alternate courses.
