You want to sell magazines? Put Rihanna on the cover

There’s a clear answer for magazine editors desperate to grow their newsstand sales: call Rihanna.

People StyleWatch logged a 6.3 percent decline in March newsstand sales with its Kate Hudson cover. From there on, things got even uglier, with magazines recording double-digit falls.

Taylor Swift and her BFF Karlie Kloss couldn’t outdo Rihanna for Vogue. The Swift/Kloss cover sold 11.2 percent fewer copies in March than Ri-Ri’s March 2014 cover.

W took a 12.1 percent drop with its Scarlett Johansson cover, while Hearst’s Esquire magazine had a 12.3 percent decline with its Will Smith cover.

InStyle logged a 16 percent drop for its Kerry Washington cover, while Glamour registered a 20.2 percent decrease with a cover featuring “Fifty Shades of Grey” stars Dakota Johnson and Jamie Dornan.
