2000 km, so I guess somewhere around the size of India.

@edit - 2000km is the size of the whole region, crater is 35 km wide. See below.

Seems to be easy to confuse since the crater seems to have the same name "Vastitas Borealis Crater" [0].
Do you know if it's actually called "Vastitas Borealis Crater" or is it just simply a crater in the region Vastitas Borealis?
> The 35-kilometre-wide crater sits 70° north of the martian equator, in a low-lying region known as Vastitas Borealis. Previous orbiters have spotted ice deposits in craters, but the High Resolution Stereo Camera on board the European probe is the first to return a three-dimensional colour image of an icy spot. The ice may be up to 200 metres thick, and lies over a dune field that has formed in the sediment on the crater's floor. The data were collected on 2 February, and this image was created for Nature last week. [1]
