If you want to set the Dock size in macOS to a specific value, you can use the Terminal to do so:

defaults write tilesize -int 32; killall Dock

This will set the icon size to 32px, and then restart Dock. Note that if you replace "write" with "read", you can get the current value of the Dock size.
