How much web space will you need? That depends on how many individual pages you will have, and how much text and image data each page will contain.

A fairly large page including a good amount of text and images in one site could be 50Kb, (or about 0.05 Mb). This means that in 10Mb of space you could have up to 200 full color pages with text and images.

If you are uncertain about how much space you will need, you can just choose an option and buy additional space as needed at a very reasonable cost.
