how do you know if webpages are too big before publishing

[jdavidmurals]

How do you check to see if the web pages I've created are too large / take too long to load and the average person's computer? Yes, I could just call a friend who is using dial up service and ask him to check out my website, but I'd have to publish it ... I don't want to publish it 'til I know it works well.

Thank you,

Trust your instinct, If you even suspect they are too big. You are
probably correct.

Instinct is great if you got one. What about those of us who are completely new to this? Isn't ther some guide lines?
Thanks
