The new iPad 5 may be 1.5mm thinner than the iPad 4 when it launches, if leaked schematics published by a French website turn out to be real.
The iPad 5 will also have a reduced width but a larger display, according to Nowhereelse.fr. It is thought that the reduced width is down to a thinner bezel around the edge of the screen of the iPad 5.
According to the site, an Apple subcontractor who worked at a machining company that is building the rear shell panel for the new iPad leaked the schematic.
It appears from the leaked images that the iPad 5 will measure 7.9mm thick, compared to 9.4mm currently, however, Nowhereelse suggests that doesn't include the depth of the screen.
The site concludes that the iPad 5 will measure 232mm long and 178.5mm wide, compared to 241.2mm long by 185.7mm wide for the iPad 4.
