How much RAM do I need in a laptop?
RAM is one of the few specs that really does change how a laptop feels to use — and one of the easiest to get wrong. Here's how much you need, explained without the jargon.
- Chromebook for web, email and video calls: 8GB is plenty (4GB at a push).
- Windows laptop or MacBook for everyday use: get 16GB. 8GB still works, but it’s the main reason laptops start to feel slow after a year or two.
- Gaming, video editing, music production or programming: 16GB minimum, 32GB if you can stretch to it.
What RAM actually does
Think of your laptop as a desk. Storage (the SSD) is the filing cabinet: it’s where all your files, photos and apps live. RAM (memory) is the desk itself: the space for whatever you’re working on right now.
A small desk is fine if you only do one thing at a time. But open a few browser tabs, a video call, a Word document and your email, and a small desk fills up. The laptop then has to keep shuffling things back into the filing cabinet, and that’s when it starts to feel sluggish, freezes for a second, or makes the fan whirr.
More RAM doesn’t make a laptop faster at one task. It stops it slowing down when you do several things at once.
How much RAM for what you do
| What you’ll use it for | Minimum | Recommended |
|---|---|---|
| Web, email, streaming, video calls on a Chromebook | 4GB | 8GB |
| Everyday Windows use: web, Office, video calls, homework | 8GB | 16GB |
| MacBook for everyday use | 8GB | 16GB (standard on new MacBook Airs) |
| Working from home with lots of apps and tabs open | 16GB | 16GB |
| Photo editing, light video editing | 16GB | 16–32GB |
| Gaming | 16GB | 16–32GB |
| 4K video editing, 3D work, running AI models | 32GB | 32GB+ |
Why we suggest 16GB for most Windows laptops
Windows 11 will technically run on 4GB, but that’s a bare minimum, not a comfortable amount. Web browsers have become much more memory-hungry, video calling apps use a lot, and updates add more over the years you’ll own the laptop.
Microsoft’s own “Copilot+ PC” laptops require at least 16GB, and Apple made 16GB standard on the MacBook Air from late 2024 — a good sign of where the baseline now sits. If you’re choosing between two similar laptops and one has 16GB for a little more money, that’s usually money well spent.
Can I just add more RAM later?
Often, no. Most thin and light laptops — and every current MacBook — have their memory soldered to the main board, so what you buy is what you’re stuck with. Some larger and gaming laptops do have a slot you can upgrade, but it’s safest to assume you can’t and buy enough from the start.
Common mix-ups
- RAM vs storage. “8GB” is RAM; “256GB” or “512GB” is storage. Retailers often list them side by side. If you see “8GB / 256GB”, the first number is the one this guide is about.
- “Unified memory” on a Mac is just Apple’s name for RAM. Macs use it efficiently, but 16GB is still the sensible choice if you’ll keep it for years.
- RAM type (DDR4, DDR5, LPDDR5X) matters far less than the amount. Don’t worry about it.
The bottom line
For most people buying a Windows laptop or a MacBook today, 16GB is the sweet spot: enough to stay quick for years without paying for power you’ll never use. A Chromebook is the main exception, where 8GB is comfortable. If you’re not sure which type of laptop is right for you, read Chromebook vs Windows vs MacBook.
