Web Server Requirement Calculation

Web Site Traffic:
This the volume in kilobytes of your files that are being downloaded to visitors computers. For live web sites your host can provide summaries through traffic analysers like AWStats or Webalizer to show how many kilobytes of traffic your site received in the past.

If your web site is not yet online, once you know the total size of your files, you can estimate your monthly traffic by multiplying that size by the expected number of visits per month. This can be a little complex, because all visitors will not look at all pages within your site.

Here are some samples:

  • Smaller web sites:
    Say you get 3,000 visitors per month (100 per day) looking at web files totaling 900 Kb. That equals 900 Megabytes (900,000 Kb) of traffic per month.

    • What could make up 370 Kb of files? A page of text can take 5-7Kb. Adding a picture averaging let’s say 65Kb on each page makes 70Kb per page, multiply by 5 pages equals 350 Kb. Add 20Kb for some JavaScript or style sheets and you have 370 Kb for 5 pages. If 3,000 visitors looked at 370 Kb of web pages your traffic is still less than 1GB per month.

  • Larger websites:
    Our website averages 20,000 visitors per month, but the traffic averages only 2,075 Mb per month. That is because most of our 300 or so web pages are text only with no graphics.
