Windshield wipers right size but leaving lots of space in between?

I can put my pinky or index finger in
between other cars windshield
wipers. But myne i can put 3, i have
the correct size ( i was at auto zone
and i checked with a few others n the
guide, its a kia forte 2015. Size 14 n
28 . I cant go any larger cuz the 14 is
right up against my car pretty much
but its too far off from the 28, is there
a fix for this? Its annoying when
looking out the passanger and having
a rain triangle half way up my car
