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.
