# Keep page weight under 1500KB
Page weight directly correlates with load time—a 1.5MB page takes 3-5 seconds on 4G mobile. Every 100KB reduction improves user experience, especially on slower networks.
## Quick Reference
- Target under 500KB for optimal performance, max 1500KB
- Images typically account for 50-70% of page weight
- JavaScript bundles are often the second largest contributor
- Monitor with performance budgets in CI/CD
## Check
Analyze the total page weight including all resources. Check if it's under 1500KB (ideally under 500KB).
