Disk space and bandwidth are two of the most common limits on a hosting plan, and they measure very different things. Understanding both helps you pick the right plan and avoid surprise warnings.
What Disk Space Measures
Disk space is the total storage your account uses on the server. It includes:
- Website files (HTML, images, PHP scripts).
- Databases.
- Email messages stored on the server.
- Backups, logs, and cache files.
Email and old backups are the most common hidden consumers of disk space. Clearing large mailboxes and removing stale backups often frees a surprising amount.
What Bandwidth Measures
Bandwidth is the amount of data transferred between your site and visitors over a month. Every page view, image download, and file upload counts toward it.
| Activity | Typical impact | |---|---| | Loading a text-heavy page | Low | | Serving large images or video | High | | File downloads | High | | Bots and scrapers | Variable |
How to Stay Within Your Limits
- Compress and resize images before uploading.
- Enable caching so repeat visitors download less.
- Keep mailboxes tidy and delete large attachments.
- Remove old backup archives from your home directory.
- Monitor usage regularly in cPanel under Statistics.
What Happens If You Exceed Them
If you run out of disk space, you may be unable to receive email or save new files. If you exceed bandwidth, your site can become temporarily unavailable until the next cycle or an upgrade. If you are regularly close to either limit, upgrading to a larger plan at my.nairohost.site is usually the simplest fix.
