What Size Is My Laptop

Whether it’s fitting your portable computer for a carrying case or bag. Or needing the physical dimensions for accurate technical support. If you don’t already know, then at some point you’ll find yourself asking, “What size is my laptop?” In what follows we’ll show you a few ways we’ve discovered to get the dimensions for a laptop. We’ll also show you how laptops are classified by screen size. We’ll also let you in on why the measurement of the display isn’t an accurate assessment of the total size of a laptop and more. So, if you’re ready, let’s jump in.

How Do I Determine My Laptop Size?

There are four ways to find out your laptop’s size. The first way is by simply measuring it yourself if you happen to have a tape measure handy. The second easiest way is by asking Windows 10.

If you have Windows 10, open the Search panel in the taskbar and type ‘Display.’ Click on the ‘Display Settings’ and click ‘Advanced Display Settings.’ You’ll see the display specs listed, including the size.

A third option is by checking the manufacturer’s site. Once you’re on the manufacturer’s website, look for your model, and check its specs. Here’s how to find out the model of your laptop.

The fourth way is by flipping the laptop over. Not always, but sometimes there may be a sticker on the bottom of the laptop that’ll give you information about your laptop’s specifications that includes its physical dimensions (usually next to the battery).  

Laptop Size Categories

The screen size reflects a laptop’s size. That’s why in the marketplace, a laptop’s size is referenced by only one number, for instance 13-inch or 15-inch rather than by its full dimensions, e.g., height, width, and depth.

Laptop sizes are divided into categories: 11- to 12-inch laptops are the lightest and they’re slim and petite.

13- to 14-inch laptops are average-size; they’re small enough to be easily portable. But large enough to give you a clear view of the display (these are mostly business-class notebooks). They typically weigh 4-pounds or less.

The standard laptop size is 15-inches, and they’re the most common on the market. They weigh between 4–6 pounds with a screen size to weight ratio that makes them popular both for daily use and gaming.

Large size laptops start at 17-inches and have displays that measure 17.3-inches. They’re also what’s referred to as, desktop replacement laptops. They’re meant for home users and professionals that require a big screen. They also get the notoriety of being the heaviest of their counterparts.

Does the Laptop’s Screen Size Really Refer to Its Width?

Now, we’re not sure why. But many laptop users think the screen size listed with the specs is actually the width. We don’t know who started the rumor, but that’s not true. You can have two laptops with the same screen size, but completely different widths.

A great example is the Lenovo ThinkPad and the Macbook Pro. Both models have a screen size of 13.3 inches. But the Lenovo’s width is 12.28 inches, while the Macbook’s width is 11.97 inches.

The screen size actually refers to the diagonal length starting from the top corner of one side of the display to the bottom corner on the opposite side, without including the bezel. The bezel is the frame surrounding the screen and doesn’t count as part of the screen for obvious reasons.

Typically, laptop sizes are listed in inches, so make sure to calculate the measurement in that unit. To make it easier for you, here’s a list of inch/centimeter standard laptop sizes:

  • 11.6 inches: 29.46 cm
  • 12.1 inches: 30.73 cm
  • 13.3 inches: 33.78 cm
  • 14 inches: 35.56 cm
  • 15 inches: 38.1 cm
  • 15.6 inches: 39.62 cm
  • 17 inches: 43.18 cm

How to Measure My Laptop Dimensions Correctly

There are many reasons why you may need to know the exact dimensions of your laptop; measuring the screen size is not sufficient. Here’s how to measure your laptop properly (you’ll need measuring tape for this job):

1.    Measuring the Width

The first step in measuring your laptop’s dimensions is measuring the width. It’s easier than measuring the screen size because you don’t have to measure horizontally and there’s no bezel to rule out. With the laptop closed, run the measuring tape from left to right on the longest side and read the measurement, that’s the width.

2.    Measuring the Depth

Now measure the laptop along the shorter surface area. To measure, hold the measuring tape from the bottom of the lid where the hinges are and run the measuring tape to the top. If your laptop’s base is deeper than where the screen hinge is, make sure to include that area in your measurement. You now have the depth.

3.    Measuring the Height

Measuring the height or thickness of the laptop is likely the easiest part—mainly because it’s the smallest part of the laptop to measure. With the laptop on flat and level surface. Start the measuring tape from the bottom of the laptop which is the flat surface it’s sitting on and run the measuring tape vertically to the very top of the laptop, raise it vertically, and then take the reading. You now have your laptop’s dimensions.

What’s the Best Laptop Size All Around?

The best laptop size depends on you. If you’re a hardcore gamer or work in graphic design, you’ll need a large screen. Users that participate in either of these activities love 15-inch laptops because while they provide an immersive enough viewing area. They’re also manageable enough to go wherever you need to go.

Once again, the most beloved laptop size for business professionals is 13- to 14-inch notebooks. These are primarily going to be Ultrabooks, which feature along with a svelte and lightweight chassis, fast wake times from sleep mode and other laptop features beneficial to a business environment, like TPM security.

On the other hand, if you don’t need your laptop to be that mobile. And you desire a larger screen real estate for an epically immersive viewing experience. DTRs (desktop replacements) have screen sizes that start at 17.3-inches and can range up to 24-inches. And as the category name suggests, these laptops are perfect for the kind of portability from their personal computer a bulky desktop just can’t offer.

Generally, the most sought-after size in the market is 15.6 inches. But that doesn’t mean it’s the best one all around. The world’s smallest laptops are a picayune 10- to 11-inches. These are mostly Chromebooks and they’re perfect starter laptops for kids.

How to Choose the Right Bag for Your Laptop

The most vital aspect to consider when buying a laptop bag is the fit. Your laptop should fit snugly inside without putting pressure on the zipper. It also shouldn’t be protruding near the four corners; that would mean the bag is a tad too small for the laptop.

Inversely, the laptop shouldn’t be moving freely inside the bag, which could cause scratches along the surface and undue wear and tear.

Furthermore, a padded compartment is essential for your laptop. It’ll absorb shocks and give your laptop some degree of protection against any tumbles. A padded bottom will serve as excellent protection, as well. In case you ever drop your bag by accident, the inside laptop will remain intact.

Summing Up

Laptops come in a wide array of sizes, each one designed to cater to a specific user. Even though 15-inch laptops are referred to as the standard size in the laptop marketplace. That doesn’t make it the right size laptop for you. The easiest way we’ve found to measure for a laptop’s total dimensions is with a simple tape measure. Then measure the longest side of the laptop starting from one end to the other, record that number. Take the tape measure and reposition it to measure the shorter side from one to the other, record that number. And finally, with the laptop on a flat surface, start from the bottom and measure vertically to get the height. In the end you should end up with: length x width x height.
