Princess Letizia of Spain often looks tiny in photos because she's standing next to her much-taller husband, Prince Felipe (whose height is estimated at 197 cm, or 6'5"). And she looked teenier than ever on September 21, when Spanish national basketball team players attended a reception at Zarzuela Palace in Madrid, including Pau Gasol (who, according to Wikipedia, is 2.13 m or 7 ft tall), and Marc Gasol (who is 7'1").
I know someone will ask me Letizia's exact height, and I haven't been able to determine that. She is apparently of average height and usually wears high heels in photos.
