What is the standard postcard size in US?
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

The United States Postal Service defines a postcard as: rectangular, at least 31⁄2 inches (88.9 mm) high × 5 inches (127 mm) long × 0.007 inches (0.178 mm) thick and no more than 41⁄4 inches (108 mm) high × 6 inches (152.4 mm) long × 0.016 inches (0.406 mm) thick.1 However, some postcards have deviated from this (for example, shaped postcards).
