Brick Size:
Bricks are made of various sizes. Normally the length should be double the width plus the thickness of one vertical joint. Thus, one stretcher along the wall will cover two headers placed across it with a joint between them. The size of brick as stated in IS – 1970.
| Detail | Length | Breadth | Height |
| Without Mortar | 190mm | 90mm | 90mm |
| With Mortar | 200mm | 100mm | 100mm |
Generally, 1 m3 brick weighs about 1800 kg. Thus, the average weight of brick will be about 3.00 to 3.5 kg.
Standard Brick Size & Weight
The ratios of L x B x H or T are so chosen that the bricks, when laid in masonry, make a pattern so that vertical joints do not come one above the other in alternate courses. Larger sizes that require a mason to use both hands to lift and place in masonry should be about 17-18 Kg and are termed as Blocks.
Importance Point of Brick Dimension
From the very beginning of the invention of bricks, the dimension of brick was very important. Because bricks are used in various construction and other ways.
So that different fields need a different size of a brick. Different shape, different formation is also required. Different countries make brick in different ways for different uses.
