A:AnswerI bought my daughter a 13" laptop and this sleeve but the laptop a bought didn't have touch screen so I ended up getting her another with a touch screen and that one is
14" and the sleeve just fits it with a little tugging so if you have a 15" it probably won't fit it.
A:AnswerFor my 14” laptop the sleeve adds maybe < 1/2 inch overall thickness. The fit is not tight, a small stack of papers can be placed in comfortably, too.
