Will a 15 laptop sleeve fit a 15.4 laptop?

Answer:

No you call for to go up to 16 sleeve. the 15.4 is if truth be told measured from inside corner of the screen to the other inside corner.so at hand will be extra area to cover.
why don't you try first.. as my experience.. im using 15 laptop too..my sleeve 15.4.. and it's fit though.. but if you still doubt.. 16 is better too..
capably 15 tends to be be square im asuming your laptop is widescreen close to mine so no it won't really fit
