Instead or in additon to monitoring the page size I suggest to optimize for performance.

So monitor the page load time and idealy also your web app's transaction performance. If you google for "real browser monitoring" you will see a some providers like AlertFox.

Another totally free option is to run the performance monitoring locally with iMacros, Google Page speed,Selenium...

Google page speed also gives you page size and # of gets ;-)
