13-inch or 15-inch: How to choose the right laptop size for you

There are a number of factors you need to take into account when buying a new laptop before you hand over your hard-earned money. In some ways, many of the different factors are linked together.

Take, for example, whether or not you should go for a 13-inch or 15-inch laptop. It's not just a simple case of "oh, I want a smaller/larger" laptop anymore. The screen size is often integrated into other specifications.

So how to make the best choice? Here's what we think you need to consider.

Where and how you'll be using your laptop

Do you travel a lot? Go to school, college or university every day and need to take your laptop with you? Whatever the reason, if you leave the house with your laptop a lot, then portability is key. Which mostly leads itself to suggest you get a smaller, 13-inch laptop that's light and easy to carry around.

However, there are laptops out there like the Dell XPS 15 (opens in new tab) which pack a 15-inch display into the frame of a 14-inch laptop. Dell isn't the only company making slim and light 15-inch laptops either. The XPS 15 is probably the best example, but others like the HP Spectre x360 15 and ASUS ZenBook Pro aren't exactly bricks while still having a larger screen.

Also consider how you'll be using it. If you're a video editor, then you'll benefit from having a larger screen. If you're predominantly writing, browsing the web, even consuming media, then you'll be fine with a 13-inch.

Dedicated graphics for gaming or creative work

It isn't just gamers that want dedicated NVIDIA or AMD graphics in a laptop. Creators, such as video editors, will also be looking for some added power in this field.

While there are 13-inch laptops out there with good graphics capabilities, traditionally this is one area that size does matter. A larger laptop means more room for a GPU, and importantly, more room for GPU cooling. So you'll not find a 13-inch Ultrabook with a GTX 1060 GPU in it. We're not quite at that magical stage just yet.

Smaller laptops, as well as thin Ultrabook-style notebooks like the ZenBook Pro tend to have either last-gen mobile GPUs or lower-end of the spectrum current generation ones. If you want a serious GPU you'll be looking for a 15-inch laptop, most likely a gaming one.

To 4K or not to 4K

Razer Blade Stealth

Somewhat tied in with the consideration for graphics, but if you absolutely need a 4K display, then you'll probably be better with a 15-inch laptop. There are smaller options, like the Razer Blade Stealth that have small, 4K displays, but generally that many pixels come on the larger size panels.

And to be honest, if you need 4K for say, video editing, then you'll probably want a larger laptop for reasons mentioned above; graphics and a physically larger screen to look at.

With 4K, or generally higher-than-Full HD resolutions, you also usually get touchscreens. Many 1080p laptops are non-touch, so factor in whether or not you desire to manipulate Windows with touch.

Ports, ports and more ports

Another byproduct of physical size is how many ports you can actually fit on the sides. As laptops become thinner and lighter, the connections on the sides are slowly disappearing.

Are you ready for a ZenBook 3 with a single USB-C port? Or do you want your HDMI, Ethernet, SD card and a bunch of USB ports? If it's the latter, then 15-inch laptops are where you'll still find the best offering. If your laptop is your only PC and you want to use it like a desktop at home, then looking at a larger notebook will give you a better chance of not needing an external dock.

Also good if you have a phobia of carrying dongles.

The bottom line

Those are some of the things we think you should consider when choosing your laptop size, but ultimately the decision is yours. Carefully look at what you'll be doing and where you'll be doing it while deciding.

The end goal is to happen upon a considered decision that leaves you getting what you need in the best package possible. If you don't need a large screen, lots of ports, a beefy GPU or a 4K display, you're probably not going to want the added size, sometimes cost of a 15-inch laptop.

See which boxes you need to tick, then see which ones the laptops you like at both sizes also tick. Then make your decision.

  • Honestly, the biggest reason why I get laptops that are 15" or larger is the Numpad. I'm not exaggerating when I say that it's come in handy in way more places than just Excel.
    Having a number pad gives you another 10+ keys at your disposal when creating keyboard shortcuts, control bindings in video games, and it's vital when you want to type special characters such as é without needing to copy and paste or use the on-screen keyboard.
    I can't see myself getting a smaller laptop than 15" because more often than not, they're missing the number pad. I'm legitimately bummed that the 15" Surface Book 2 doesn't have the number pad. They probably could've squeezed one in.
  • Precisely this!  Everything we have gets a numpad, 15.6 Lenovo's are our baseline.  Sure we have some Surface Pro 3/4's, as well as some older MacBooks, but they all also get full size Logitech Kbd/Mouse combos. Our shop people would find creative ways to "kill" a non-numpad equipped device.....  
  • @N_Studios, I generally agree, but for the specific point of entering special characters, like é (0233) or ç (0231), you can do those on laptops that have an embedded numeric keypad the same you would with a dedicated numeric keypad. Of course, it does need to at least have a NumLock key (one of my small convertible tablets, the Thinkpad Yoga 260 does not, my other, a Fujitsu T904, does).
  • One *disadvantage* of 4k/high resolution screens is that Windows applications *traditionally* didn't scale properly to higher resolutions. Thus, some applications will have menus where you need a screen magnifier to read the menus on high resolution screens. You can always reduce the resolution, but then -- why buy a high resolution screen at all? OK -- applications that adhere to MS's UI APIs, etc. probably don't have problems with this, but I have had serious problems with Adobe programs in the past, not to mention other (free) tools, etc. These programs are gradually reducing the problem, but problems may still show up.
  • @LIEBER, this problem is pretty much gone. Each successive version of Windows 10 has gotten better about dealing with legacy apps on high-DPI displays. Most work well automatically now. For those that don't, when they're open, you can right-click on their icon in the Taskbar, then irght-click again on their icon in the pop-up (yes, this is weird in that you need to right click on one of the results of a right-click, only place I know where you do that), and select Properties. on the Compatibility tab, check "Override high DPI scaling behavior" and try the various options in the drop-down. Depending on your system configuration and resolution, some values there may work much better than others. Hit OK and it's saved for that application. Note that you can only do this for legacy apps. UWP apps don't offer a Properties option from the Taskbar and some other native Windows 10 applications don't include a "Compatibility" tab, but I believe this works for just about all applications where the DPI issue could be a problem.
  • Thanks! Very useful -- I will test it when I come upon the problem again.
  • Just curious, with the Surface Book 2 coming out how much of a difference will the GPU performance be between the 13" & 15"?  I'm looking at playing lite video games with the XBox Play Anywhere while travelling.  Will the 1050 vs. 1060 be the equivalent of the XBox One S vs. X?
