27 x 19.1 x 3.8

The Belkin F8N140 neoprene sleeve is made from a solid, stretchable material, with sturdy stitching and a little protection so that the zipper does not scratch against the netbook.

The internal dimensions which are found difficult on the Internet, are, according to the packaging:
27 x 19.1 x 3.8 cm.

Unfortunately, my Eee PC 1005PE with a mass of 26.2 x 17.8 x 2.59 ~ 3.65 cm too much air in the envelope and slipped back and forth.

So overall a perfect product, which unfortunately had not only the right size for my netbook.
