Question: What Is the Size of Linux Kernel?
Contents

An ordinary stable 3* kernel is about 70 mb now. But there are little linux distributions of 30-10 mb with software and other stuff running out of the box.

What is the size of kernel?

So, in the end, the complete size of the kernel in memory will differ a lot depending on the machine and the peripheral devices it uses. It may be just a few hundred KB. Normally (PCs and servers), it’s a few MB. Sometimes, it may be over 10MB.

How do I know my kernel size?

Measuring the kernel image size

The size of this image can be obtained by examining the size of the image file in the host filesystem with the ‘ls -l’ command: for example: ‘ls -l vmlinuz’ or ‘ls -l bzImage’ (or whatever the compressed image name is for your platform.)
