I originally ordered the 14 inch size for the Thinkpad X1 because the X1 has a 14 -inch screen has. It turned out to be too big. The external dimensions of the size 14" are 14 3/16" x 10 1/2". I sent it back and got a size 13-13.3 which turned out to be perfect. I use it as a backpack case and in this one Senses it's perfect.If you want you can put the charger in your pocket and it will fit but no more.Photos size 13-13.3.
