I can't remember what length my OEM wipers were, but if I recall, they were a length that made them hard to find or the price was crazy.
I am since using 28" wipers which are easily found, do more than enough area for clearing the windshield, and because they may be a little shorter, allow the wiper motor to move them more easily. I also have sleeves to protect them from UV rays, and that keeps them soft like new.
Remove just one of your present wipers, notice the design for attaching and take it with you. Wally World or any automotive supply store should fit you up.
Don't forget to clean the inside too.
