It really depends on the features you select and optimization level too.
See https://mcuoneclipse.com/2018/03/03/flash-resident-usb-hid-bootloader-with-the-nxp-kinetis-k22-micro... where it shows different configurations.

Thank you very much.
I only wanted to have a general idea of required size.
By the way, I follow your blog and I find it very useful to learn MCUXpresso tricks.
Thank you :-).
To give you an idea:
My bootloader (McuBoot) for the K22 supporting USB HID needs around 18KB Flash and 8 KB RAM (-Os)
