Mary-Kate Olsen and Ashley Olsen Height

"Stay true to what makes you happy, because that always ends up producing the best result."

~ Ashley Olsen

Mary-Kate Olsen and Ashley Olsen are twin sisters who are successful fashion designers and used to be successful actresses before that. The duo is popularly known as the Olsen twins.

Olsen twins are almost identical in everything -- including their height -- they are known to be petite and tiny.

This is kind of surprising as they are reported to be actually fraternal twins, not identical twins. fraternal twins can be very different from each other -- but that's clearly not the case here.

Anyway, IMDb lists Mary-Kate's height at an impressive 5-feet-2 inch -- the only problem with this listing is that Mary-Kate doesn't even look close to 5'2" -- nor does Ashley looks close to her listing of 5-feet-1 inches.

From what we have seen of them, Ashley certainly looks the taller one, but not by an inch.

Their younger sister Elizabeth Olsen towers over them like a younger sister should never do -- we suppose she is around 5-feet-5 inches tall. Below is our official guess for the twins' height. We aren't putting this lightly -- this number is the result of some deep dive into the sordid world of celebrities' height.

The height of Mary-Kate Olsen is

4'11" or 150 cm

The height of Ashley Olsen is 

4'11½" or 151 cm
