The first thing to know when comparing the sizes of the MacBook Air and XPS 13 is that, yes, it is a pretty fair comparison: both have the same display size at 13.3 inches. While we're talking display, though, the XPS 13 has a lot more options and a lot more pixels to offer than the MacBook Air. The new XPS 13 provides three choices for its display: an FHD (1,920 x 1,080 resolution) touch display, an FHD non-touch display, and a 4K/UHD (3,840 x 2,160) touch display. The MacBook Air, on the other hand, doesn't have any touchscreen options and includes display resolution that feels a bit dated at this point, with 1,440 by 900 pixels. Also worth noting: the MacBook Air display uses standard LCD technology rather than Apple's much-loved Retina display technology, which is found in all other Mac laptops.
