Buying a laptop is a major investment, and with hundreds of models in every price range, it’s easy to get lost in the specifications. These tips help you make a well-informed decision and find a laptop that suits how you’ll actually use it.

1. Size and weight matter

Think about how often you’ll carry your laptop. If you take it to work, university or on trips every day, a 13- to 14-inch model weighing around 1.2–1.5 kg is much more comfortable. If it mostly stays on a desk, a 15- or 16-inch screen gives you more room to work, and you can save money or get more performance. Battery life matters too: for a full day away from a socket, look for real-world tests rather than the manufacturer’s figure.

2. Choose the right operating system

Windows laptops offer the widest choice and software compatibility, MacBooks are known for long battery life and build quality, and Chromebooks are cheap and simple if you mainly use the browser. If you depend on specific programs or games, check that they run on the system you choose.

3. Get the key specs right

• Processor: a current mid-range chip from Intel, AMD, Apple or Qualcomm is plenty for office work, browsing and streaming. Gamers, video editors and engineers need more power and often a dedicated graphics card.
• Memory: 16 GB of RAM is a good standard today; 8 GB is the bare minimum for light use.
• Storage: always choose an SSD; 512 GB is a sensible size for most people.
• Screen: a bright display with at least Full HD resolution is easier on the eyes; OLED panels offer excellent contrast.

4. Try the keyboard and touchpad

You’ll use the keyboard and touchpad every day, so try them in a shop if you can. Modern touchpads are large and precise, but if you prefer a mouse, a wireless one costs little. A backlit keyboard helps when working in dim light.

5. Check the ports and wireless features

Wi-Fi and Bluetooth are built into every laptop today, but check for Wi-Fi 6E or Wi-Fi 7 support for the best speeds with a modern router. Make sure the laptop has enough ports for your devices — many thin laptops only have USB-C, so you may need an adapter or dock for older USB devices, an external monitor or a card reader. Laptops that charge via USB-C are convenient, because one charger can power several devices.

6. Set a budget — and stick to it

Decide how much you want to spend before you start looking, and don’t pay for performance you’ll never use. When you’ve found a laptop you like, wait a day, check reviews and compare prices — sales periods, student discounts and certified refurbished models can save a lot.

7. Think about warranty and support

Check the warranty length and what it covers, and consider accidental-damage protection if the laptop will travel a lot. Good manufacturer support and the availability of spare parts and repairs can make a laptop last much longer.
