"How much RAM do I need?" is the question we're asked most often. Buy too little and your system stutters; buy far too much and you've spent money you didn't need to. This guide breaks it down by what you actually do, with sensible recommendations for 2026.
A quick word on how RAM works
RAM (memory) is your computer's short-term working space. The operating system, every open app and every browser tab live here while in use. When you run out, the system falls back to much slower storage, and that's when everything feels sluggish. More RAM doesn't make a fast task faster, but it stops you grinding to a halt when you're doing a lot at once.
8GB: the bare minimum
8GB is now genuinely entry-level. It's fine for a basic laptop used for web browsing, email, light word processing and streaming video. For anything more demanding it fills up quickly, especially with a modern browser and a few tabs open. We'd only recommend 8GB for the lightest, most budget-conscious machines.
16GB: the comfortable everyday standard
For most people, 16GB is the sweet spot. It comfortably handles:
- Office work with many tabs, documents and spreadsheets open at once
- Mainstream gaming at good settings
- Home use, light photo editing and general multitasking
If you're buying a everyday desktop or laptop and aren't sure, 16GB is the safe, well-balanced choice.
32GB: the enthusiast and creator standard
32GB has quietly become the default for power users. Choose it if you:
- Game at high settings while running Discord, a browser and streaming software
- Edit photos in large batches or do moderate video editing
- Run virtual machines, containers or large development projects
- Simply like to keep dozens of tabs and apps open without thinking about it
For new mid-to-high-end builds in 2026, 32GB is increasingly what we'd suggest as a starting point.
64GB and beyond: professional and specialist workloads
64GB, 128GB or more is the territory of serious professional work:
- 4K and 8K video editing and colour grading
- 3D rendering, CAD and simulation
- Running multiple virtual machines simultaneously
- Large datasets, data science and local machine-learning work
- Servers hosting many services or VMs
If your applications specifically recommend large amounts of memory, follow their guidance. For everyone else, 64GB+ is usually more than you need.
Servers and virtualisation
Server and VM hosts are a different game. Each virtual machine reserves its own slice of RAM, so capacity adds up fast, and you'll often want ECC memory for stability. Size based on the number and type of guests you'll run, plus headroom for the host itself.
A few practical tips
- Run in pairs. Two matched modules enable dual-channel mode for better performance than a single stick of the same total capacity.
- Check your motherboard's maximum. Boards have a supported ceiling and a fixed number of slots.
- Leave room to grow. Filling two of four slots now lets you add more later.
On our store you can filter by capacity to jump straight to 8GB, 16GB, 32GB or 64GB+ kits, alongside type and form factor, so you only see modules that suit your needs.
The short version
8GB for the lightest use, 16GB for everyday machines, 32GB for enthusiasts and creators, and 64GB+ for heavy professional and server work. When in doubt, 16GB or 32GB will serve the vast majority of people very well.
