Laptop fit guide for work bags.
Measure your laptop with its case on, then compare its width, depth and thickness with the usable sleeve and its opening. Two 14-inch laptops can need different pockets. Start with the actual dimensions below.

Check your laptop against a bag pocket
Subtract the laptop’s outside size from the pocket’s usable size in each dimension. For example, a 315.9 mm wide ThinkPad exceeds a 314 mm pocket by 1.9 mm. Include any case and repeat the check at the narrowest part of the opening.
| You usually carry | Start with | Check before buying |
|---|---|---|
| Laptop and a few documents | Briefcase | Laptop pocket dimensions and how a folder sits beside it. |
| Laptop and things you take out often | Messenger | Can you reach the right pocket without setting the bag down? |
| Laptop, charger, layers and a bottle | Backpack | Room for a packed charger and bottle without crowding the laptop. |
| Phone, keys and wallet | Sling | Opening width and how the strap adjusts over a coat. |
Measure the sleeve you intend to use
Measure the closed laptop across its longest and shortest edges, then measure its thickness at the thickest point, including the case. Check the clear opening where the laptop enters and the space inside the pocket. Try the opening again with the charger and bottle packed. A pocket that looks roomy when empty can be harder to reach when the bag is full.
Separate the hard objects
Lay out your laptop, charger, mouse, bottle and anything else you bring most days. Decide where each will sit. Move a thick power adapter out of the sleeve so the fit check reflects the way you’ll pack it.
Check the bag against the journey
Try the loaded shape against the chair, transit seat or bike setup you use. If you reach for an access card while standing, favor a pocket you can open while wearing the bag. If you often set the bag on a desk, look for a base and opening that give you the access you need.
A common question
Will every 14-inch laptop fit a bag marked 14-inch?
Screen size measures the diagonal of the display. For fit, compare the closed laptop’s outside dimensions with the pocket and the narrowest point of its opening. Include any case you carry, and check the opening again with the bag packed.
