How Much RAM Do You Need for Windows 11 in 2026?
Microsoft just deleted its own 32GB RAM advice for Windows 11 as prices soar. Here's how much RAM UK PC buyers actually need in 2026, tier by tier.
Microsoft just deleted its own 32GB RAM advice for Windows 11 as prices soar. Here's how much RAM UK PC buyers actually need in 2026, tier by tier.
Microsoft spent the best part of a year telling Windows 11 users that 32GB of RAM was the "no worries" upgrade. This week, without a word, it deleted that advice from its own support pages, right as it launches 8GB Surface devices and RAM prices sit at some of the highest levels UK buyers have seen. If you're trying to work out how much RAM you actually need for a Windows 11 PC in 2026, the honest answer has very little to do with what Microsoft's marketing team wants to say this month, and everything to do with what you actually run.
Two separate Windows Learning Centre articles that recommended 32GB for gaming and general use have gone, both now redirecting to the Learning Centre homepage. At the same time, Microsoft has been talking up memory-footprint improvements for Windows 11 itself, due by the end of the year, and shipping new Surface Pro and Surface Laptop models with 8GB as the base configuration.
Read the two things together and the story isn't really about Windows getting leaner. It's that DRAM has become expensive enough that recommending 32GB as a baseline is now awkward for a company that also wants to sell 8GB machines at a straight face. We've tracked that price pressure ourselves on the UK RAM price index, where kit prices rose over 3% in a few months earlier this year, and the trend hasn't reversed. Whatever Microsoft's support pages say this week, the underlying hardware maths for a PC buyer hasn't changed.
Microsoft's official minimum for Windows 11 is still 4GB. Treat that number as fiction. Windows itself idles at somewhere around 3GB before you've opened a single application, which leaves no working headroom at all. It's a compatibility floor for installers, not a usable spec.
8GB is the realistic floor, and it's what most budget laptops and pre-builts still ship with. It'll get you through a browser, email and office documents, provided you don't open too many tabs at once. It is not a comfortable spec for gaming, and it is not a spec you should be paying full price for on a desktop build in 2026.
16GB is where Windows 11 stops fighting you for memory during ordinary use, and it's also the minimum Microsoft itself requires for a system to qualify as a Copilot+ PC capable of running on-device AI features. That's a useful tell: even Microsoft's own AI ambitions assume 16GB as the real baseline, whatever the support docs say about 8GB being "fine."
Treat this as tiers by workload, not a single number.
Fine for a secondary machine used for browsing and streaming. Not worth building or buying new for anything you intend to game or multitask on. If a pre-built quotes 8GB as standard, budget to upgrade it or walk away.
For the majority of gamers and general users, a matched 2x8GB or 2x16GB DDR5 kit is the sensible starting point in 2026. Most current AAA titles are comfortable here, and Windows 11 has enough headroom left over for background apps without constantly paging to disk. If you're speccing a build around one of the CPUs and motherboards we track, 16GB is the default assumption behind almost every current buying guide, ours included.
Streamers, anyone running a browser with dozens of tabs alongside Discord, Spotify and an office suite, and gamers on the more memory-hungry recent titles will feel the difference. It's also the sensible ceiling if you want a build that won't need a RAM upgrade for the next three or four years. Given current pricing, 32GB now carries a real premium over 16GB, so treat it as a deliberate choice rather than a default.
Video editors, anyone running virtual machines, and the growing number of enthusiasts running local large language models on their own hardware genuinely use this much. Most gamers don't, and buying 64GB "to be safe" at today's prices is money that would do more for your build going into a faster SSD or a better GPU.
Part of why 16GB systems can feel tighter than they should is that a lot of what eats memory on Windows 11 isn't visible in a spec comparison. Background AI features tied to Copilot have been measured pulling over a gigabyte on their own, Microsoft Teams has a well-earned reputation for sitting heavily in the background, and Windows' own prefetching behaviour (SysMain/Superfetch) is designed to pre-load memory with data it thinks you'll want, which inflates "used" memory figures well beyond what your actual applications need. None of that shows up when a manufacturer prints "8GB" or "16GB" on a box.
The practical upshot: don't just count gigabytes against a game's minimum spec. A developer running a browser, Outlook, Teams and an IDE at once can max out 16GB on ordinary office work alone, long before a game ever loads. If your day-to-day workload already looks like that, size up.
Always buy RAM as a matched dual-channel kit (2x8GB, 2x16GB and so on) rather than a single larger stick. Single-channel memory can cost you real bandwidth and noticeably worse frame-time consistency in memory-sensitive games, and it's a mistake that's easy to make when a single stick looks cheaper on the shelf. Two matched sticks from the same kit is the only sensible way to buy for a gaming or general-use build.
Faster-rated kits aren't automatically worth the premium if your CPU and motherboard can't make full use of them, and going too high on a budget without checking supported speeds is a common way to overspend. Our guide to choosing the right RAM covers where EXPO and XMP profiles actually make a measurable difference and where they're marketing noise.
If you're upgrading rather than building fresh, confirm which standard your existing motherboard takes before you buy a kit. DDR4 pricing has held up better than DDR5 through this shortage in some tiers, which can make a like-for-like upgrade on an older platform more affordable than jumping to a new one purely for the memory spec.
Buy for the machine you actually use, not for whatever number happens to be in a support article this month. For most UK PC buyers building or upgrading in 2026, 16GB in a matched kit is the sensible default, 32GB is worth the extra spend if you multitask hard or want a build that lasts, and 8GB belongs on a secondary machine, not a primary one. Check current kit pricing across brands on our RAM category page before you buy, and browse the wider catalogue on all products if you're pricing up a full build rather than a single upgrade.
