How do you calculate bandwidth from page views?

We multiply page views by average page size to get total bytes, convert to bits, divide by the number of seconds in the selected period, and then add headroom for bursts and inefficiency.

What average page size should I use?

Typical modern pages range from 1–3 MB. Measure using browser devtools (Network tab) for the most accurate result.

What's the difference between bandwidth and monthly data transfer?

Bandwidth (Mbps) is the sustained rate required to serve traffic. Monthly data transfer is the total amount of data transferred over a month.

Should I include bot traffic and caching misses?

Yes — include an appropriate redundancy factor (e.g., 1.1–1.3) to allow for bot traffic and cache misses. Use real analytics data when possible.

How the Calculation Works

Page views × page size

Calculate total bytes transferred

Bytes to bits conversion

Convert to bits per second (bps)

Apply headroom & redundancy

Account for traffic spikes and overhead

Formula

Total bytes = Page views × Page size

Bits per second = (Total bytes × 8) ÷ Period seconds

Final = bps × Redundancy × (1 + Headroom%)

Best Practices

Measure actual page sizes using browser DevTools Network tab
Include API calls, fonts, and third-party scripts in calculations
Plan for 20-30% headroom during marketing campaigns
Use presets as starting points and adjust based on analytics

Calculation Example

100,000 page views/month × 0.5 MB/page × 1.2 redundancy = normalize to 30 days → convert to Mbps

Quick Reference

Key considerations

Normalize monthly traffic to 30 days
Factor in cache-miss scenarios
Consider compression ratios (typically 60-70%)

Common Scenarios

Personal Blog

5-10k views/month, 1-2 MB pages

E-commerce

50k+ views/month, 2-3 MB pages

News Site

100k+ views/month, 3-5 MB pages

Why It's Important

Knowing required bandwidth helps choose the right hosting plan and avoid throttling or overage charges.
