16GB is the working minimum for modern development, 32GB is the comfort zone. It depends on your stack — here is the breakdown.

Quick answer
Most programmers should have 16GB as a minimum and 32GB as the comfortable target. Web development with an IDE, browser, and a local server fits in 16GB. Android development, Docker-heavy backends, microservices, or running databases locally push you to 32GB. 64GB is for data engineering, multiple VMs and very large monorepos.
Contents
By type of development
| Stack | Minimum | Comfortable |
|---|---|---|
| Web (VS Code, Node, browser) | 8GB | 16GB |
| Full-stack + Docker + local DB | 16GB | 32GB |
| Android (Android Studio + emulator) | 16GB | 32GB — see Android Studio guide |
| Game dev (Unity/Unreal) | 16GB | 32GB |
| Data science / ML | 16GB | 32–64GB (dataset-dependent) |
What actually eats developer RAM
It is rarely your editor. The hogs are: the browser with documentation and app previews, Docker containers, language servers indexing a big repo, an emulator or simulator, and Slack/Teams running alongside. Count 2–4GB for the OS, then stack your tools honestly.
Laptop buying advice
Developer laptops increasingly come with soldered RAM. If you cannot upgrade later, buy 32GB now if your stack includes Docker, Android, or VMs — it is the difference between a machine that lasts five years and one that swaps itself to death in year two.

Frequently asked questions
Can I learn to code on 8GB?
Yes — tutorials, small projects and web development basics run fine on 8GB. You will only feel the limit when the tool stack grows (Docker, emulators, big IDEs).
Does more RAM make compiling faster?
Only indirectly: enough RAM keeps the compiler and filesystem cache out of the pagefile. CPU cores dominate compile times once you pass the ‘not swapping’ threshold.
