The Best Backpack For Your New MacBook (2021)

What’s the best laptop backpack for the new line-up of MacBook sizes in 2021?

If you’re Apple aficionados like us, then you’ve already purchased one of the new MacBooks with a speedy M1 Processor, or you’re dreaming about the day when you finally do. But after spending upwards of $6,000 for one of these beauties, you’ll want to protect your investment with the best laptop backpack around (a Knack Pack, obviously). 

Since Apple has changed the sizing of the new 2021 MacBooks, we’re going to go over these changes, and walk you through which Knack Pack is the perfect match for each new MacBook size.

Apple's 2021 MacBook Sizes

Model Actual Length (diagonal, frame edge to frame edge)
13" MacBook Air 13.3"  
13" MacBook Pro 13.3"
14" MacBook Pro 14.2"
16" MacBook Pro 16.2"


How MacBook laptop sizing works

The way that laptops are sized can get a little confusing. For Apple Products, the ‘MacBook size’ actually indicates the diagonal screen size of the laptop, not the laptop’s (or screen’s) frame-edge to frame-edge measurement. In Apple’s newer MacBooks, the screens take up a larger percentage of the frame, so the actual dimensions of the laptop will be different than what the MacBook name indicates. When looking for a bag, to be safe, it’s always important to research the laptop’s true frame-edge to frame-edge dimensions.

The best laptop backpack for a MacBook Pro 14"

The 14” MacBook Pro will fit in any Medium Series 1 or Series 2 Knack Packs, all of which have a 15+” laptop pocket opening. The next-best option for a 14" MacBook Pro is the Small Series 1 Knack Pack, although the pocket would be a bit tight.

The best laptop backpack for a MacBook Pro 16"

A 16” MacBook Pro will fit into a Large Series 1 or Series 2 Knack Pack, both of which have a 17+” laptop pocket. You can also fit the 16" laptop into the Medium Series 1 or Series 2, although the pocket would be very snug.

Does the laptop pocket have to be sized exactly to match my MacBook?

No, in fact, it’s nearly impossible to find a laptop pocket that your MacBook will fit into snugly. And because Knack’s laptop pocket is padded, a little wiggle room won’t hurt at all. In fact, a small margin of space will allow you to more easily pull your laptop in and out of the pocket. Of course, make sure that there isn’t too much space, because you don’t want your laptop to get jostled unnecessarily.
