**NOTE: I think the other ppl who answered this question are referring to The Smithsonian Museum of African American History. The question (and my answer) are about The Smithsonian Museum of African Art.** We spent about 75 mins there. It's not a huge museum and it's not usually super crowded. Amount of time needed for museum visit depends on whether you like to breeze thru the exhibits or take in all the info and details.
I spent about 3 hours, it just depends on the person
2 hours
2-3 hours is more than enough
We spent all day. Lots to see.
