There are many different browsers out there - Too many to list! While 70% of Web surfers use Internet Explorer, you can't just ignore the remaining 30%! The chart below shows just how many people are using one of the four most popular browsers. Keep in mind that there are many more browsers besides these and each one has a different way of interpreting HTML code. That means your page could appear differently on each browser!

1% and 2% of users doesn't seem like a lot, but when you consider that's one million customers, it could change your opinion!

Numerous versions of each browser - They are continuously updating and improving browsers to accommodate the ever changing Web. While it's important to test your page under the latest version of each browser, don't forget about the users who are using an older version of that browser. Below you will see the percentage of users who are not using the latest version of their preferred browser.

Variety of screen resolution sizes - There are different screen resolutions at which your monitor can be set. Roughly half of all users choose the 800 x 600 pixel screen size. Approximately 40% set their screen size to 1024 x 768 and 10% use a 640 x 480 size. Each of these resolutions can change the layout of your page by increasing or decreasing its size. View the examples below:

Different computer platforms - There are PC's, MAC's, and now WebTV - each with a different operating system. Not all operating systems have the same features, fonts, colors, etc. which could cause your page to appear differently. Even though Windows has a 90% monopoly on the market share, you can't forget about the other 10%. To put it bluntly, you could be eliminating a little over 5.5 million potential customers!

Range of font sizes - Did you know that you can change the size of the font that you view within your browser? Go to "view" on your menu and select "text sizes". There are 5 different sizes a user can choose from and each one can change the way your site appears!
