Schippers believes she can leap seven metres, a feat that would put her among the top six performances of 2015.
"I want to do something else other than just sprint," the former heptathlete told a news conference on the eve of Friday's Diamond League meeting in Brussels.
However, Schippers said she would focus on the 100, 200 and 4 x 400 relay at the Rio Olympics next year.
The long jump is nothing new to the world sprint champion because she holds the Dutch record of 6.78 metres from her heptathlon days.
"I train for the long jump every two weeks," said Schippers.
