What is Bandwidth in Web Hosting?

Bandwidth vs data transfer — defined

Bandwidth is the total data your site transfers between server and visitors in a month — measured in GB. The essentials:

• Every page view, image download and file transfer counts toward it.

• Monthly GB ≈ average page weight × page views. A 1.5 MB page at 10,000 views is about 15 GB.

• Hosting plans are unmetered (no counting) or metered (quota with consequences).

• Images and self-hosted video are the biggest eaters; a CDN absorbs most of the load.

• 'Unlimited bandwidth' means unmetered within fair use — read what happens at the limit.

Normal business sites, blogs and stores never approach modern shared hosting limits — the math and the fine print below tell you when you actually would.

The math — estimating your monthly GB

The formula: monthly transfer ≈ average page weight × page views, plus downloads, email and API traffic.

Worked example: average page 1.5 MB (a reasonably optimised WordPress page), 30,000 monthly views — about 45 GB. Add a 50 MB PDF downloaded 200 times (10 GB) and email traffic, and the month lands near 60 GB — well within any unmetered plan, and under most metered ones.

The eaters that break the math: unoptimised photography (WebP conversion cuts 30–60 percent), self-hosted video (5 GB per hour per viewer — use YouTube/Vimeo or a CDN), and bot crawlers hammering large sitemaps. Cutting usage — CDN, compression, caching, hotlink protection — keeps the number boring, which is exactly what you want it to be.

What happens at the limit — suspend, throttle or overage

TTL is how long a resolver may cache a DNS answer. After an edit, people who cached the old record keep it until that timer ends, so the change can look instant for you and old everywhere else. Drop the TTL a day before a migration, make the change, and raise the TTL once you have confirmed the new target.

Unmetered and unlimited — reading the fine print

Two practical notes on page size math: it interacts directly with caching and database response, and misconfiguration is the most common cause of 'hosting is slow' tickets. WebJi® support checks it as part of standard migrations.

Cutting usage — CDN, compression, caching, hotlink protection

Put a cache in front of pages that do not change per visitor, and keep cart, checkout and account pages uncached. After a DNS or cache change, test in a private window so your own browser cache does not lie. Lower the DNS TTL a day before a move, then raise it once the new target is confirmed.

Planning headroom for viral and sale days

How this plays out with overage charges: settings that look cosmetic usually decide page speed and uptime under real traffic. The defaults WebJi® ships are tuned for Indian network conditions, and support can review your setup on request.
