My 15-inch laptop does not fit in a bag advertised for 15-inch laptops — why?

Screen size advertised on bags is a guideline, not a guarantee. The 15-inch designation means the bag was designed for a typical 15-inch laptop, but laptop widths vary by manufacturer — a 15-inch Razer Blade is 3 cm wider than a 15-inch MacBook Pro. Additionally, the bag may list the opening size rather than the interior compartment depth, making laptops with thick lids appear not to fit. Measure your laptop and compare to the bag's stated compartment dimensions.

Will a 13-inch laptop fit in a 15-inch bag?

Yes, with extra room. The 13-inch laptop will fit in the 15-inch compartment with approximately 2-3 cm of gap on each side. This is fine for carry but the laptop may shift in the compartment. A snug-fitting sleeve for the laptop inside the compartment eliminates the shifting problem.

Can I fit a 17-inch laptop in a 16-inch bag?

Typically no. A 17-inch laptop is approximately 2-4 cm wider than a 16-inch laptop and will not fit in a 16-inch compartment. The compartment would need to be explicitly sized for 17 inches. Few standard laptop bags accommodate 17-inch laptops — search specifically for bags sized for 17 or 17.3-inch laptops.

My laptop fits but the zipper does not close all the way — what do I do?

If the laptop fits the opening but the zipper will not pull fully closed: the laptop is near the compartment's thickness limit. Try removing any protective case from the laptop — even a 2mm rubber case can be the difference between fitting and not fitting. If the laptop without a case still will not allow the zipper to close without force: the bag is too small. Do not force the zipper.

Most laptop bag fit problems are one of two issues: the laptop is thicker than the bag was designed for, or the correct orientation/installation technique was not used. Measure before returning.
