About Web Hosting Storage Calculator

Media libraries dominate storage on most sites, growing far faster than page count. Backups multiply the requirement, so the retained-copy count matters as much as the live size. Storage is usually the cheapest hosting dimension to over-provision, and running out mid-year is disruptive.

Web Hosting Storage

Storage = content + media + database, compounded by growth over the horizon
