TL;DR
- Small PRs (<400 lines) reviewed 5× faster than large PRs (>1000 lines).
- Automate style enforcement (Prettier, ESLint); focus reviews on logic and architecture.
- <24 hour review SLA prevents blocked developers and context loss.
Code Review Best Practices: Speed and Quality for Startup Engineering
Code reviews prevent bugs, spread knowledge, and maintain quality -but slow reviews block progress. These code review best practices balance speed and rigour with small PRs, automation, and async-first workflows.
Key takeaways
- PRs >400 lines rarely get thorough review; split into smaller chunks.
- Automated checks (lint, test, type coverage) catch 80% of issues before human review.
- Review SLA: first response <4 hours, approval/changes <24 hours.
