These large wall calendars (11.5 inches by 18 inches when open) are printed on premium heavyweight paper that holds up well whether you display your calendar on a wall or put it into heavy use on your desk. These are not only for keeping track of dates — they make wonderful wall art!​ Each photo is 11.5 by 9 inches.
