What size cork bulletin board should I buy?

For a home office or kitchen command center, most reviewers recommend 24x36 inches as the sweet spot, large enough for calendars, photos, and notes without dominating a wall. Dorm rooms and small entryways generally do better with an 18x24 or 17x23 board. If you need to display posters or run a family planning hub, step up to 48x36.
