How Big of a Backpack Do I Need for a 17-inch Laptop?

If you have a 17-inch laptop and want to carry it around, you’ll need a backpack that is slightly larger than it. You’ll need a bag with a 17-inch laptop sleeve or an opening that is about 18 by 11 inches minimum. 

This post will explore what size of backpack you need for a 17-inch laptop. I’ll highlight some information you should keep in mind while looking at different bags for your laptop and provide some other related tips. 

Let’s get to it. 

Key Takeaways

  • You need a backpack that is slightly larger than a laptop to fit a 17-inch computer. 
  • If you have a bag with a 17-inch laptop sleeve, it will fit a 17-inch laptop. If it’s a smaller sleeve, it won’t fit a computer that size. 
  • As long as your bag has an opening around 18 by 11 inches, it should fit a 17-inch laptop. 

How Big of a Backpack Do I Need for a 17-inch Laptop? 

Whenever you carry a laptop, you want to ensure it’s well-protected, so it doesn’t bounce around while you’re on the move and get damaged. A 17-inch laptop is relatively large, so you’ll need a backpack large enough to handle it. 

If you are looking at a modern backpack that comes with a laptop sleeve, you’ll want to get one that is 17 inches to match the size of the laptop you have. If you get a smaller-sized sleeve, you likely won’t be able to fit a 17-inch laptop inside it. 

If you are just looking at all types of backpacks, regardless of whether it has a laptop sleeve, you need one with a slightly larger opening than how large the laptop is. 

So, for a 17-inch laptop, you’ll want a backpack with at least one opening that is 18 by 11 inches. This gives you about an inch on either side of the laptop for extra room. If you go smaller than that, the laptop might not fit. 

Since even larger laptops aren’t that thick when closed, you don’t need to worry much about the thickness of your laptop in relation to the backpack. You’ll be able to fit it inside the sleeve or pocket as long as it fits in the bag’s compartment. 

Most average-sized backpacks should be able to fit a 17-inch computer. But not all of them will have laptop sleeves to give you a secure fit. It’s a good idea to get a case of some kind for your laptop to protect it while in the bag. 

Best 17-inch Laptop Backpack

Many factors come into play when deciding the best option for a backpack with a 17-inch backpack. The best choice for you depends on which features and functions you want or need. 

I always like to get a backpack with a dedicated laptop sleeve. This will help prevent the computer from slipping and sliding around while you have the bag on. You’ll need a 17-inch laptop sleeve for a 17-inch backpack. 

But you also should consider other features such as the overall size or volume of the bag, the type of material it is made of, and the total cost. These factors all contribute to figuring out which is the best for you. 

If you need to carry a 17-inch laptop and a lot of other stuff, you’ll want a larger backpack with multiple pockets. If you don’t need to carry much more than the laptop, you can get away with using a smaller backpack. 

If you live in a location that gets a lot of rain, consider using a backpack that has waterproof material to keep your laptop protected. You also might want a specific color or material. 

Cost is another big concern here. If you are on a budget, the best bag will be one that is cheap and can still hold a 17-inch laptop. If money is not an issue, you can choose any model that works best for the rest of your needs.
