Is there a maximum size that web pages should be kept under?

Question

When I say size I\'m talking about bytes not pixels.

I\'m curious if there is any consensus on what the maximum size should be for various categories. Specifically

Answer 1

Depending on the connection you want the page loading in as less time as possible. Less than 4 seconds is optimal.

"A study conducted by leading web traffic controller Akamai Technologies revealed that a poorly designed website loses a full 30 percent of its customers within a few seconds. The same study also found that if a site takes longer than four seconds to load, 75 percent of viewers won’t bother to return to it." http://www.ianbrodie.com/get-clients-online/lose-website-visitors-in-5-minutes/

More important than size is following some simple rules and best practices.

So a rough estimate would be

Broadband connections   ~200K
Dialup connections      ~50k
Mobile connections      ~100K
