Apple is reportedly considering launching a 14in version of the MacBook Air, sources in the company's supply chain have claimed.

Digitimes reckons that mass production of such a device could begin in the near future and that Apple would use it to aggressively target the Chinese market, as well as other Asian markets.

The 14in form factor is the "mainstream specification of the Asia notebook market", Digitimes says, whereas European and North American consumers prefer a 15in laptop.

Models with a 14in display only account for between 20 and 25 percent of the market, while in Asia the market share for 14in models is closer to 40 percent, the report says.

Currently Apple offers the MacBook Air in two screen sizes - 13.3in, which was the original MacBook Air, and a newer, smaller 11.6in model.

Apple is already rumoured to be working on a 15in thin-and-light model, though whether this is a new, larger MacBook Air or a revamped MacBook Pro is up for debate.

However, the MacBook Air line-up is due an overhaul, having last been refreshed in June 2011, and it is believed that the new models will sport Intel's Ivy Bridge processors and architecture.
