How Much RAM Do I Need in Laptop UK 2026 Guide

If you are trying to work out how much RAM you need in a laptop, you are probably staring at two similar models — one with 8GB, one with 16GB — and wondering whether the extra £80 or so is worth it. The honest answer in 2026 is: yes, almost always. Three things have changed recently that make this a more important question than it used to be. First, Windows 10 reached end-of-life in October 2025, pushing millions of people onto Windows 11, which is noticeably more RAM-hungry than its predecessor. Second, Microsoft has set 16GB as the hard minimum for Copilot+ AI features — if you buy an 8GB laptop today, you are permanently locked out of Windows’ entire AI feature set. Third, most modern thin-and-light laptops now have RAM soldered directly to the motherboard, which means whatever you buy is what you are stuck with for the life of the device. This guide walks through every use case — from basic browsing to 4K video editing — so you can make the right call before you hand over your money. If you are also unsure about other specs, our laptop buying guide covers everything from processors to storage.

What Does RAM Actually Do?

RAM — short for Random Access Memory — is your laptop’s short-term workspace. It holds everything the laptop is currently doing: your open browser tabs, the document you are writing, the app running in the background playing music, the video call you are on. The more RAM you have, the more the laptop can juggle at once without slowing down.

When RAM runs full, your laptop starts moving data to the SSD instead — a process called “paging” or “swapping.” The SSD is dramatically slower than RAM, even on the fastest NVMe drives. The moment paging kicks in, you notice it: tabs reload when you switch back to them, apps take longer to respond, and the whole machine feels sluggish even though nothing obvious has changed. This is exactly what happens on a busy 8GB Windows 11 laptop.

RAM is different from storage. Storage (your SSD or hard drive) is where your files are saved permanently — photos, documents, programmes. RAM is temporary: it only holds what the laptop needs right now. The two are often confused, but they do different jobs. More storage does not compensate for less RAM.

The Short Answer: How Much RAM Do You Need?

Here is the quick-reference table. Find your main use case and you will have your answer. Most people land in the 16GB row.

Your main use	Minimum RAM	Recommended RAM	Notes
Basic browsing, streaming, email	8GB	16GB	8GB works but feels limited with multiple tabs open
Students (university, coursework)	16GB	16GB	Future-proofs for 3–4 years of study
Office work (Word, Excel, Outlook)	8GB	16GB	16GB needed for Teams/Zoom alongside Office
Work from home (WFH)	16GB	16GB	Video calls + Office + browser tabs eat RAM quickly
Photo editing (Lightroom, Photoshop)	16GB	32GB	32GB for large raw photo catalogues
Video editing (1080p)	16GB	16GB	16GB adequate for straightforward 1080p timelines
Video editing (4K)	32GB	32GB	Premiere Pro and DaVinci Resolve both recommend 32GB
Gaming (casual / indie titles)	8GB	16GB	8GB fine for older/lighter games; 16GB for modern AAA
Gaming (AAA, modern titles)	16GB	16GB	Most 2026 AAA titles list 16GB as minimum spec
Coding / programming	16GB	16GB	32GB if running Docker, VMs, or multiple dev environments
Windows AI features (Copilot+)	16GB	16GB	Microsoft’s official minimum — 8GB laptops are excluded
Local AI / running LLMs	16GB	32GB	32GB+ recommended for running medium-sized models locally
3D design / animation	32GB	64GB	High VRAM workloads also require more system RAM

Notice how 16GB appears in the recommended column for almost every everyday use case. That is not a coincidence — it is the practical baseline for a Windows 11 laptop you expect to use for three or more years.

4GB RAM in 2026: Avoid It

Windows 11’s official minimum requirement is 4GB of RAM. That number is technically accurate and practically useless. Windows 11 itself uses approximately 2.5GB of RAM at idle — before you have opened a single app or tab. That leaves you with roughly 1.5GB for everything else: your browser, your email client, your music app, your antivirus. It is not enough.

On a 4GB Windows 11 laptop, everyday tasks feel painful. Switching between a browser tab and an Office document causes noticeable lag. Running a video call while doing anything else is genuinely uncomfortable. The laptop is not broken — it is simply overwhelmed by the demands of a modern operating system.

The one exception is Chromebooks. Chrome OS is a much lighter operating system than Windows and uses far less memory at idle. A 4GB Chromebook is perfectly adequate for browsing, email, Google Docs, and video streaming. But if you are buying a Windows laptop, treat 4GB as off the table entirely. It was marginal in 2022 and it is not acceptable in 2026.

8GB RAM: Fine for Now, But Check Your Options

8GB is the minimum workable amount of RAM for a Windows 11 laptop in 2026. For genuinely light use — browsing a handful of tabs, streaming a film, writing in a single document — it functions without drama. The problem is that most people’s “light use” is heavier than they think. Open Teams for a call while keeping a browser tab with your notes and an Excel file in the background, and an 8GB laptop will start slowing down.

The more significant issue is Copilot+ compatibility. Microsoft has set 16GB as the hard minimum for Copilot+ PCs — its new category of laptops with built-in AI features, including Recall (which lets you search everything you have ever done on your computer), live captions, and AI image generation tools. An 8GB laptop bought today is permanently excluded from these features. Not just now, but forever — because on most modern thin-and-light laptops, the RAM is soldered to the motherboard and cannot be upgraded.

Most laptops with 8GB of RAM sit in the £300–£500 price bracket at Currys and John Lewis. The step up to 16GB at the same spec level typically adds roughly £80–£150 to the price — a meaningful but manageable gap. If your budget is genuinely tight, check our best laptops under £500 guide, where our picks all come with 16GB where possible. If you are choosing between an 8GB model and stretching slightly for 16GB, stretch.

16GB RAM: The Sweet Spot for Most People

For the vast majority of UK laptop buyers in 2026, 16GB is the right answer. It handles everything most people need: a full working day with Teams, a browser with a dozen tabs, Office apps running concurrently, and a few things ticking along in the background. It does not struggle. It does not page to SSD. It just works.

Students should treat 16GB as non-negotiable. University software has a habit of being memory-hungry — research tools, data analysis packages, CAD software for engineering students, creative apps for design courses. A 16GB laptop bought in 2026 should remain comfortable throughout a three or four year degree. Our best student laptops guide lists 16GB models across every budget tier.

For work-from-home setups, 16GB is also the practical minimum. A typical WFH day involves video calls (Teams, Zoom, Google Meet), multiple browser tabs, email, and some form of productivity software — all open at the same time. 8GB gets uncomfortable fast in that scenario. 16GB handles it without complaint. If you work from home regularly, see our best laptops for working from home — all tested for remote work scenarios.

For light creative work — editing photos in Lightroom on a weekend, putting together a short video from holiday footage — 16GB is adequate. For more serious creative workloads, read on.

32GB RAM: Who Actually Needs It?

32GB is not for everyone, but for certain users it is genuinely necessary rather than a luxury.

Video editors working in 4K: Both Adobe Premiere Pro and DaVinci Resolve 20 recommend 32GB of RAM for 4K editing workflows. With 16GB, you can open 4K footage — but you will likely see dropped frames during playback, slow timeline scrubbing, and occasional crashes during complex colour grading. With 32GB, the same workflow is noticeably smoother. For 6K, 8K, or multi-camera 4K projects, 64GB is the sensible target.

Photographers with large catalogues: Lightroom and Photoshop both benefit significantly from 32GB when you are working with large raw files or processing batches. Adobe recommends 16GB as a minimum for Lightroom, but 32GB is where performance becomes comfortable for professional volumes of images.

Developers running Docker or virtual machines: If you regularly run Docker containers or spin up virtual machines as part of your workflow, 16GB will feel tight. Each VM can consume 2–4GB of RAM on its own, and running two or three alongside your development tools and browser quickly saturates 16GB. 32GB gives you comfortable headroom, and 64GB if you run particularly demanding environments.

Local AI and LLMs: Running AI models locally — whether that is a medium-sized language model or image generation tools — requires substantial RAM. Small models can run on 16GB, but anything meaningfully capable needs 32GB or more. This is a niche use case for most people, but it is worth knowing if you are planning to experiment with local AI tools.

32GB laptops typically start around £700–£800 at UK retailers. If none of the above scenarios match your use case, you do not need 32GB — and spending the extra money on it when 16GB would do is genuinely unnecessary.

Soldered vs Upgradeable RAM: The Decision That’s Hard to Undo

This is the point most articles miss, and it is arguably the most important practical consideration when buying a laptop in 2026.

In most modern thin-and-light laptops, the RAM is soldered directly to the motherboard during manufacture. There is no slot, and you cannot add more later. What you buy is what you have for the entire life of the laptop. This means that buying an 8GB laptop today is not “I can always upgrade later” — it is “I am committing to 8GB for the next four or five years.”

Some laptops, particularly business-class models and larger gaming machines, still use SO-DIMM RAM slots — a physical slot you can pull the RAM out of and replace with a higher-capacity module. These are the laptops where you can buy at 16GB and upgrade to 32GB later if your needs change.

Laptops with soldered RAM (cannot upgrade):

• All Apple MacBooks (M-series chips)
• ASUS ZenBook range and ROG Zephyrus G14
• HP Spectre x360
• Dell XPS 13 and XPS 15 (2020 onwards)
• Lenovo ThinkPad X1 Carbon Gen 11 and Gen 12
• Most thin-and-light consumer laptops using LPDDR5 memory

Laptops with upgradeable RAM (SO-DIMM slots):

• Lenovo ThinkPad T14, T14s, and T16 Gen 5 (DDR5 SO-DIMM, upgradeable up to 64GB)
• Dell Inspiron 15 and 16 Plus (two DDR5 SO-DIMM slots)
• Most gaming laptops (ASUS TUF, Lenovo Legion, Acer Nitro — check the spec sheet)
• Some Dell Latitude business models

One thing to watch: the ThinkPad P1 Gen 7 introduced LPCAMM2 — a new, thinner module format that is still user-replaceable, unlike traditional LPDDR5. It is the first of its kind, and it suggests the industry may be moving toward a new upgradeable standard. For now, though, always check the specification sheet before buying. Look for the words “SO-DIMM” or “upgradeable memory.” If the spec sheet says “LPDDR5” without mentioning a slot, assume it is soldered and cannot be changed.

If you are buying an upgradeable laptop and plan to add RAM later, be aware that RAM prices in 2026 are elevated due to a global DRAM shortage. A 16GB DDR4 SO-DIMM module costs roughly £45–£55 via UK retailers like Mr Memory or MyMemory, but DDR5 SO-DIMM is significantly more expensive. Factor this in when comparing the cost of buying 16GB now versus buying 8GB and upgrading.

RAM Types Explained: DDR4, DDR5, LPDDR5

When you look at laptop specs, you will see RAM described with labels like DDR4, DDR5, or LPDDR5. Here is what they mean in practical terms — you do not need to memorise the technical details, just understand the key differences.

DDR4 SO-DIMM: The older standard, still found in many mid-range and business notebooks. Physically sits in a removable slot, so it can be upgraded. Slower than DDR5, but the real-world difference in everyday tasks is small.

DDR5 SO-DIMM: The newer standard on Intel Core Ultra and AMD Ryzen AI platforms. Also upgradeable via slot. Faster than DDR4, and supported by the latest Lenovo ThinkPad T-series and some Dell Inspiron models. The speed improvement over DDR4 is real but modest in everyday use.

LPDDR5 / LPDDR5X: The “LP” stands for Low Power. This RAM is soldered to the motherboard and cannot be replaced or upgraded. It is faster and more efficient than SO-DIMM DDR5, which is why manufacturers use it in thin, premium laptops — it helps battery life and enables slimmer designs. But it locks you in.

How much does speed actually matter? Less than you might expect. Real-world testing shows that moving from LPDDR5-4800 to LPDDR5-5600 — faster RAM of the same type — delivers less than a 3% improvement in everyday tasks like browsing or working in Office. Compile times improve by around 7%. Nothing dramatic. The amount of RAM you have matters far more than how fast it runs. A 16GB LPDDR5 laptop is a much better buy than an 8GB LPDDR5X laptop, even if the latter technically has faster memory on paper.

What About Apple MacBooks? (Unified Memory Explained)

Apple uses a different approach with its M-series chips, where the RAM and the processor share the same pool of memory — Apple calls this “unified memory.” For several years, Apple (and many reviewers) argued that 8GB of unified memory performed like 16GB of traditional RAM, because the M-chip’s memory bandwidth is so much higher than a conventional setup.

That argument has always had some truth to it — Apple’s M-series memory bandwidth runs at around 60GB/s, compared to roughly 40GB/s for DDR5 SO-DIMM, and the tight integration between CPU and GPU reduces overhead. An 8GB M-series Mac does handle multitasking better than an 8GB Windows laptop.

But in 2026, Apple itself has moved on. The M5 MacBook Air — launched in early 2026 — now starts at 16GB across all models. Apple has quietly dropped the 8GB baseline. This is as clear a signal as you can get that 8GB is no longer adequate even in Apple’s own estimation, regardless of how efficient the unified memory architecture is. If you are buying a MacBook in 2026, start at 16GB. All current MacBook models come with soldered unified memory, so there is no upgrade path — what you configure at checkout is what you have permanently.

Which Laptop Is Right for Your RAM Needs?

Now that you know how much RAM you need, here is where to find the right laptop at your budget.

Everyday use and home browsing

For everyday use — browsing, streaming, email, light Office work — go for 16GB. You will not use it all on a quiet day, but you will be grateful for it when you have ten tabs open and a video call running. Our everyday laptops roundup lists tested options across the £400–£700 range, all with 16GB as standard.

Students

University use is demanding in ways students often do not anticipate — especially in the final year, when multiple large documents, research databases, and specialist software can all be open at once. 16GB is the right call, and it should be adequate for most courses through to graduation. Check our best laptops for students guide for picks at every student budget, including options under £600 with 16GB.

Working from home

WFH users tend to have the most RAM-heavy daily workloads of any “non-creative” user group: Teams or Zoom running continuously, browser-based tools, cloud platforms, and productivity software all competing for memory. 16GB is comfortable; 32GB is worth considering if you work in a technically demanding role. Our best laptops for working from home covers the best options with an eye on build quality and battery life for all-day use.

Budget-conscious buyers

If you are working with a tight budget, our best laptops under £500 guide filters for 16GB options where possible. In that price range, 16GB models do exist — you may need to look slightly harder, but the extra effort is worth it to avoid locking yourself into 8GB.

Frequently Asked Questions

Is 8GB RAM enough for a laptop in 2026?

For very light use — a handful of browser tabs, streaming video, working in a single document — 8GB is workable. But it is no longer comfortable for most people’s actual daily usage. Windows 11 uses around 2.5GB at idle, leaving limited room for apps. If you regularly have Teams, a browser with several tabs, and an Office document open at the same time, an 8GB laptop will start to slow down. The bigger issue is that most 8GB laptops sold today have soldered RAM, meaning you cannot add more later. If you can stretch to 16GB at purchase, it is worth doing.

Is 16GB RAM overkill for everyday use?

No. 16GB has become the sensible baseline for a laptop you plan to use for three or more years. It handles everyday multitasking comfortably, meets Microsoft’s minimum requirement for Copilot+ AI features, and gives you headroom as websites and apps get heavier over time. If your budget allows 16GB, choose it over 8GB — you will not regret it, but you might regret the 8GB.

Can I upgrade my laptop’s RAM later?

It depends on the laptop. Most modern thin-and-light laptops — including all Apple MacBooks, ASUS ZenBook, HP Spectre, Dell XPS, and many others — use LPDDR5 RAM soldered directly to the motherboard. You cannot add or replace it. Upgradeable laptops include the Lenovo ThinkPad T14/T14s/T16 series, Dell Inspiron 15/16 Plus, and most gaming laptops. Always check the specification sheet before buying — look for “SO-DIMM” or “upgradeable memory.” If it says “LPDDR5” without mentioning slots, assume it is soldered.

What is the real difference between 8GB and 16GB in daily use?

The most noticeable difference is in multitasking. With 8GB, opening Teams alongside a browser with ten or more tabs and an Office document will cause the laptop to slow down, tabs to reload, and apps to occasionally stutter. With 16GB, the same scenario runs smoothly. The difference is less about raw speed and more about how often the laptop has to move data between RAM and the slower SSD — when RAM runs full, performance drops sharply. Most people who switch from 8GB to 16GB describe it as a transformation in perceived speed, even on the same hardware.

Do I need 32GB RAM for video editing?

For 4K video editing, yes — 32GB is the practical recommendation. Adobe Premiere Pro and DaVinci Resolve 20 both recommend 32GB for 4K workflows. With 16GB you can open 4K footage, but you may see dropped frames during playback, slow renders, and crashes during complex effects. For 1080p editing, 16GB is sufficient. For 6K, 8K, or multi-camera 4K with colour grading, 64GB is advisable.

Is 4GB RAM enough for a laptop in 2026?

No. Windows 11’s minimum is 4GB, but the OS uses around 2.5GB at idle — leaving almost nothing for your apps. A 4GB Windows 11 laptop will feel slow even for basic tasks. The only scenario where 4GB is acceptable is a Chromebook, where Chrome OS is far lighter than Windows and 4GB is sufficient for everyday use. If you are buying a Windows laptop in 2026, treat 8GB as the absolute floor and 16GB as the sensible choice.

Does RAM speed matter for laptops?

Less than you might think. Real-world tests show that moving from LPDDR5-4800 to LPDDR5-5600 delivers less than a 3% improvement in everyday tasks like browsing or Office work. You will see small gains in compile times (around 7%) or video renders, but nothing dramatic. What matters far more is how much RAM you have, not how fast it runs. A 16GB LPDDR5 laptop is a significantly better buy than an 8GB LPDDR5X laptop, even if the latter has faster memory on paper. Prioritise capacity first, speed second.
