We use laptops every day, whether that’s work, study or just relaxing at the end of a busy one. But one thing that sometimes gets overlooked is knowing the correct size and screen dimensions of your laptop.

So, in this article, we're going to dive into the details of measuring your laptop's size. We'll clear up the difference between screen size and overall laptop dimensions. Then walk you through the steps to measure each one accurately, explain how manufacturers determine screen size, and give you some handy tips on choosing a laptop bag that fits. Rulers at the ready!

Why knowing your laptop size is important

Knowing your laptop dimensions goes beyond whether it’ll slide into a new backpack! It’s important to bear in mind for lots of good reasons:

1. Picking the right accessories – whether it’s screen protectors or keyboard covers, these little lifesavers are made to fit specific laptop models. So accurate measurements mean they’ll stick properly and do their job.

2. Buying a new monitor - Understanding your laptop's screen specs is another biggie. Knowing the screen size and resolution helps when you want to upgrade or buy an external monitor. If you're into high-definition content or gaming, you'll need a monitor that matches or beats your laptop's screen quality.

3. Setting up a workspace – Sometimes the most obvious things are overlooked. If desk space is limited, accounting for every mm can be vital. And by the time you’ve filled it with a new keyboard, mouse and multiple screens, you might find there’s no room left for your actual laptop! Plus, it helps you pick the right docking stations and stands that suit your laptop’s size.

How to measure your laptop’s screen size

To measure your laptop’s screen size diagonally, a simple tape measure or ruler will do the trick. Here’s a step-by-step guide to help you out:

1. Turn off your laptop

Make sure your laptop is turned off to avoid any accidental inputs while you measure. Especially if you own a touchscreen.

2. Open the laptop flat

Open your laptop to its fullest extent so that the screen is fully visible and flat.

3. Measure from the right place

Starting from the bottom left corner of the screen (not the frame, but the actual display area) place the end of your measuring tape or ruler.

4. Measure diagonally

Extend the measuring tape or ruler to the top right corner of the screen. Make sure you are measuring straight across the diagonal of the screen without including the bezels or frame.

5. Make a note of the measurement

Take note of the measurement you get. This is the diagonal size of your laptop screen, usually expressed in inches.

What tools do you need to measure your laptop?

To accurately measure your laptop screen, there are a few tools you can use:

• Measuring tape: A flexible measuring tape allows you to easily measure the diagonal length from one corner of the screen to the opposite corner. Simply extend the tape from the bottom left to the top right corner, ensuring it is straight and taut.

• Ruler: A standard ruler can also be used for this purpose, though it may be less convenient for larger screens. Place the ruler diagonally across the screen and read the measurement.

• Web search: If you can’t find a ruler, you can always just google the make and model of your laptop and get the exact specs online.

How to measure the overall size of your laptop

To measure the height, width and thickness of your laptop accurately, it’s a bit more involved. Laptop dimensions can all be measured by closing your laptop and measuring the top cover where the logo usually is.

So, get your tape measure ready and let’s go through one measurement at a time:

Height

Close your laptop completely and measure the height, from the bottom edge to the top edge of the cover.

Width

Close your laptop completely and measure from the leftmost edge to the rightmost edge of the cover. Make sure the measuring tape or ruler is straight and even for an accurate reading.

Thickness

With the laptop still closed, measure from the bottom of the laptop's base to the top cover. Make sure to include any rubber feet in your measurement to get the total thickness.

Understanding the difference between screen size and laptop size

Don’t mix them up! To make sure you’re getting the laptop you actually want, it’s important to know the difference between screen size and laptop size.

What is screen size?

Screen size refers to the diagonal measurement of the display area of your laptop, typically measured in inches. This measurement does not account for the bezels or any other parts of the laptop body.

What are laptop dimensions?

Laptop dimensions include the height, width and thickness of the laptop. Always measure the top cover when your laptop is closed.

Choosing the right laptop bag based on size

Laptops are portable PCs, so be sure to follow these tips before buying a bag that matches.

Measure your laptop correctly

The last thing you want is for your swishy new bag to turn up and be too small or big to carry your laptop! You’ll obviously want a laptop bag where your laptop slides in snugly.

Check bag specifications

Look for the internal dimensions of the laptop bag. Ensure that these dimensions are slightly larger than your laptop’s measurements.

Leave a bit of space

If you plan to carry additional accessories like a charger, mouse or keyboard, go for a bag with extra compartments. However, the primary laptop compartment should still fit your device securely.

Padding and protection

Opt for a bag with adequate padding to protect your laptop from bumps and shocks. Look for features like reinforced corners, water-resistant materials and secure closures.
