How much storage does a website actually need?
The short answer
Far less than you think. A normal website with dozens of pages and images fits comfortably in 5 to 10 gigabytes. Entry plans with 10 to 25 gigabytes are plenty for most sites. Only with lots of video or thousands of products does storage become a real criterion.
In detail
Web pages themselves are tiny. Images and files are what add up. An average photo, properly sized for the web, weighs a few hundred kilobytes. Even with hundreds of photos you stay under a gigabyte. A WordPress install with a theme and plugins lands at a few hundred megabytes, and a mailbox usually grows faster than the site itself.
Marketing slogans about unlimited storage sound attractive but are irrelevant for a normal site. What matters more is the type of storage. Modern NVMe or SSD drives make your site noticeably faster than old-fashioned disks, and Hostinger and A2 Hosting lead with that in their plans.
The exceptions are real. If you host your own video (use YouTube or Vimeo instead), run a photo archive, or sell thousands of products, then check the numbers. Everyone else can choose on speed and service, not gigabytes.
