The doors look like they are 2'-0" to 2'6" each, to give a 4'- 5' total width opening. If I count the floor tiles, I'd estimate this pantry to be about 5'x5' clear floor space - probably 6' to the walls behind the shelving.

A corner pantry sounds great, remember to assess how much you have to store and if you you will have clear space around the pantry doors to access it freely. (So that you factor in 1'-2' free area around the 4'x4' area, so you aren't bumping into adjacent walls, counters, etc...)
