how much web space If you look at the previous bandwidth example page we assumed the page size was an average of 25kb. If your host allowed you 20mb of space you could host around 800 pages. Don’t forget that if you use a database that could eat up 10mb but you’d still have enough space to load up 400 pages. Of course if your selling a product or two, say ebooks) that each takes up 1.5mb in space that would reduce your space further. However for the average site anything over 30mb in web space is usually more than enough.
