The file size depends on the target and what modules you use, for dynamically linked projects I would guess it's around 50mb for an average project. Maybe 20mb more on windows because of the icu libs, but those can be replaced with your own (much smaller) versions. Static projects may weight half of what the dynamic ones do, so maybe around 25mb. But depending on how much you care about file size, you could also compile your own static Qt version and then strip everything that you don't need.

Here [1] are some infos about QML development and here [2] you can try out QML in the browser.
