The left lung (which has two lobes) has to be smaller than the right lung (which has three lobes) because space on the left side is occupied by the heart and its associated blood vessels.
The heart, while basically in the center of the chest, has more of its mass on the left. This means there is less space in the pleural cavity of the left thorax than the right. An image of the lungs alone reveals that there is also something displacing the bottom portion of the left lung. I'm not sure why this is.
Hello
why the left lung is smaller than the right one?
Because it is below the heart.

It is smaller because the heart is located toward the left side of the chest.
The heart is (mostly) on the left side and takes up some space.
The right lungs of all mammals have three lobe while left with two lobe due to presence of heart in that place and that place is called cardiac nothc.
because your heart takes up space and your heart is on the left side of your body
since heart is not in the middle of our body it relies on the left lung(2 lobes) what makes it smaller than the right one.
Because the heart is underenath the left lung and the right one doesn't have anything under it.
We have 2 lungs, of not equal size. The left lung is smaller than the right lung to give room for your heart.
The left is smaller, due to the presence of cardiac notch
The left lung only has 2 lobes (superior and inferior) because the heart takes up much of the space allowed on the left side. The right lung; however, has 3 lobes (Superior, Middle, and Inferior). Yes. The left lung is a little less voluminous than the right lung. It has two lobes, whereas the right lung has three. Its volume is displaced a bit more, by the location of the heart, than the right lung.
The left lung is smaller than the right.
The right lung is slightly bigger due to the heart. The heart takes up more room on the left side so that the right lung has more room on the right side.
Its bigger because the right lung has more lobs then the left lung.
You are talking the left chambers both times. The left ventricle has larger walls because it pumps blood to most of the body, while the right ventricle pumps only to the lungs. The left pumps blood through the arteries to the body. The right side pumps blood through veins to the heart. The left atrium and left ventricle are larger than their right counterparts.
The right lung is slighty bigger than the left.
Your heart is not on the center line of your body for several reasons. Your left ventricle has to pump a lot stronger than the right ventricle. Your left ventricle has to pump blood all over your body. Your right one just pumps blood to your lungs which are right there. The right side is smaller than your left side. Since the right side of your heart is smaller than the left side of your heart, that makes more room on the right side of your chest. Since your body will have more room on the right side of your chest than on the left side, that means your lung will have more room on your right side. Still, it will not have enough room to do anything. But, if It moves your heart a little bit more over to the left, it can put a lobe in your lung to the right. That way your lung can have three lobes on the right side and two lobes on the left side.

There are four steps on how to draw a rib cage when the rib cage is inhaling. Some of the step-by-step instructions are draw the frame lining, draw out the right view of the rib cage, and then finish drawing out the beginning sculpture of the building blocks for the rib cage.
The right lung is shorter than the left by 1 inch (2.5 centimeters) however, the total capacity of the right lung is greater than the left. The right lung has three lobes, the left lung has two. If you need to know the "why" then its simply in the human genetics that your lungs will never be identical unless you suffer from a mutation of the genes
