What size bag do I need for my laptop?

If your laptop is one of your most relied upon tools for school, work or entertainment, then it probably goes everywhere with you. Thus, having a dedicated place to keep your laptop while travelling is essential.

But with so many options available, how do you know which size backpack is right for you?

How to measure your laptop

To determine which size bag is best for you, you should first measure your device.

You’ll need:

  • The diagonal - make sure this includes the bezel around the display!
  • The width and height
  • The depth or thickness
Laptop measurements

How to tell if your laptop bag will be big enough

Most bags are measured two ways - volume and dimensions (W x H x D) - and you can find this information on the product page online.

Unfortunately, volume is not always indicative of whether or not your laptop will fit. For example, the Lefrik Handy backpack has a volume of 12L, but it’s slim profile and wide rectangular design allow it to carry laptops up to 15.5inch.

On the other hand, the Vans Construct Skool backpack has a volume of 21L, but can only fit most laptops up to 15inch.

So, it’s better to use the width, height and depth measurements available on the product display and compare them to your laptop’s measurements to determine if your laptop will fit in the bag. You should always aim to have a bit of wiggle room left around your bag to avoid overstretching the material or damaging the zip , but it should still be snug and secure. However, pay attention to shape of the backpack - bags with a curved top mislead you into thinking they are high or wide enough. Read the description of the bag carefully to find our if it will fit your laptop.

Useful features of a backpack for your laptop

  • Laptop sleeve/pocket - a dedicated spot for your device to help keep it secure. It’s also worth considering if the laptop sleeve has added padding which offers more protection
  • Waterproof fabric and zips - essential for commuters who have to make the journey come rain or shine
  • Security features like zip clips - helpful in keeping your laptop extra safe during your journey
  • Separate pockets - it is advised to keep your plugs separate from your screens.
  • Internal organiser - helps keep your cords, pens and other accessories tidy
  • Padded or ergonomic straps - to promote comfort and good weight support.

The bag needs to suit your needs, so choose accordingly. If you know you need a lot of storage, pick a backpack with different compartments. To make your search a little easier, we’ve put together a shopping guide including some of our most popular laptop backpacks.
