    1

    Start by asking what you will actually use it for

    ~26s
    Before reading any specs, write down the three main things you plan to do on the device. Browsing and email? Streaming movies? Video calls? Photo editing? Gaming? Your intended use is the most important factor in deciding what specs matter. A computer for browsing and email needs very different specs than one for photo editing. Once you know your use case, you can filter out the specs that do not apply to you.

    Check RAM first — it affects everyday speed the most

    ~42s
    Find the RAM specification on the product page. It is listed in gigabytes (GB). For everyday browsing, email, and video calls, 8 GB is the minimum you should consider. If you regularly have more than ten browser tabs open, use office software, or do light photo editing, choose 16 GB. Be aware that most modern laptops have RAM soldered directly to the motherboard, meaning it cannot be upgraded later — so it is worth choosing the right amount upfront rather than planning to add more.

    Quick Tip

    Quick Tip: If you are deciding between two otherwise identical laptops and one has 8 GB RAM and the other 16 GB for an extra $50 to $100, the 16 GB model is almost always worth the upgrade for long-term usefulness.

    3

    Confirm the storage type and size

    ~29s
    Look for SSD (Solid State Drive) in the storage specification. If the listing says HDD or Hard Drive, the computer will be a lot slower to start up and open programs. SSDs have come down in price and are now standard on most laptops above $400. For storage size, 256 GB is workable if you store most files in the cloud, 512 GB is comfortable for most people, and 1 TB (1000 GB) is ideal if you keep a large photo or video library on the device.
    4

    Look at battery life for portable devices

    ~29s
    For any laptop or tablet you plan to use away from an outlet, find the battery life claim on the spec sheet. Manufacturers test battery life under ideal conditions, so real-world use is usually 70 to 80 percent of the stated figure. A laptop rated for 12 hours will likely last 8 to 9 hours with the screen at normal brightness running typical tasks. For a device you want to use all day without plugging in, look for a claimed battery life of at least 12 hours.
    5

    Ignore specs that rarely matter for everyday use

    ~29s
    Many spec sheets include numbers that sound impressive but make no practical difference for regular users. Processor GHz clock speeds matter less than the processor generation (a newer processor at a lower GHz often outperforms an older one at a higher GHz). RAM speed in MHz rarely makes a noticeable difference for everyday tasks. The number of processor cores matters for video editing and 3D work, but not for browsing or email. Focus on the specs that align with how you will actually use the device.

    When you are shopping for a laptop, tablet, or desktop computer, the product page is full of numbers and technical terms that can feel overwhelming. The good news is that for most everyday users, only about five of those specs actually matter for how the device will feel to use day to day.

    The first is the processor, also called the CPU. This is the brain of the computer. For everyday tasks like browsing the internet, watching videos, video calls, and writing emails, any modern processor from the last three to four years will be more than fast enough. You only need to pay close attention to processor performance if you plan to edit videos, work with large spreadsheets, or run demanding programs.

    The second is RAM, which stands for Random Access Memory. Think of RAM as your desk space — the more RAM you have, the more things you can have open and running at the same time without the computer slowing down. For browsing, emails, and streaming, 8 GB of RAM is fine. If you like having many browser tabs open at once, or you use productivity software, 16 GB is noticeably better. Video editors and people who run multiple demanding programs should look for 32 GB.

    The third is storage. This is where your files, photos, and programs are saved. You will see two types: HDD (Hard Disk Drive) and SSD (Solid State Drive). Always choose an SSD if you have the option. It makes the computer start up in seconds and makes programs open much faster. For storage space, 256 GB is a minimum for most people, 512 GB is comfortable, and 1 TB is generous.

    The fourth is the display. For laptops, 13 to 15 inches is the most portable range. Resolution of 1080p (Full HD) is perfectly sharp for everyday use. Higher resolutions like 1440p or 4K give you a crisper image but reduce battery life.

    The fifth is battery life. For a laptop you plan to take anywhere, look for at least 10 hours of claimed battery life. Real-world battery life is usually 70 to 80 percent of the claimed figure.
