I running OS X 10.6.8 on a Mid-2009 MacBook Pro. I would like to standardize the size of icons seen in Finder (I use Icon View). Currently, every folder has its own icon size, which makes it less comfortable to use. I am tired of trying to "guesstimate" using the icon slider. Ideally, I would like to either revert all folders to default sizing, or be able to specify, for example, 48px.

I would also like to, if possible, revert the dock to default icon size (or at least be able to specify by pixel, and desktop icons also.

Is there an easy way to do this?

You can change the default size in the view options panel:

The sizes of icons are also stored in .DS_Store files that override the default setting. You can delete them by running sudo find / -name .DS_Store -delete, but it also resets other display options and removes Spotlight comments. The changes aren't always picked up until you quit and reopen Finder.

I don't know if I understood you correctly but:

By choosing Show View Options from the View menu, ( or just doing Command+J ) you can, precisely, specify the icon's size in pixels. And, if not in the desktop but in a folder, you can set this size as default.

Also, under ~/Library/Preferences you can find the Dock's preferences. At the end of the file, you can find its size in pixels. Although I expected that editing the file and reloggin to do the trick, it, instead, created a new preferences file, so it was a lot easier just to change the value on the slider (under System Preferences / Dock) and checking its numerical value on the file.
