Bandwidth describes connection capacity, while data transfer describes how much data is actually delivered over a period. Hosting plans commonly measure transfer monthly.

Large images, video, downloads, scripts, and frequent requests can all consume transfer.

Estimate Usage

Multiply average page size by page views for a rough estimate. A 2 MB page viewed 10,000 times represents roughly 20 GB before caching and compression are considered.

Reduce Unnecessary Transfer

• Resize images.
• Use modern image formats.
• Compress text responses.
• Use browser caching.
• Consider a CDN when appropriate.
• Review logs for unusually large requests.

Always check the actual resource definitions of a hosting plan because providers measure limits differently.
