The front wiper blades are 22 inches on the driver’s side and 21 inches on the passenger’s side, with a 13-inch blade for the rear window.
These sizes apply to the Jeep Wrangler JK model years 2007 through 2018, including both two-door and four-door variants. When shopping for replacements, confirm the exact measurements on your current blades or in your owner’s manual, as aftermarket sets can vary and some trims or options may use different lengths.
Front wiper blade sizes for the JK
The two front blades on a Wrangler JK use different lengths to properly cover the windshield without overhang. This pairing is standard across most JK configurations and years.
- Driver’s side blade: 22 inches
- Passenger’s side blade: 21 inches
These dimensions apply to most 2007–2018 Jeep Wrangler JK models, including both two-door and four-door variants. If you’re replacing just one blade, check the size printed on the blade packaging or the blade itself to confirm.
Rear wiper blade (JK)
Some JK models with a rear wiper use a single blade dedicated to the rear window. The standard size is 13 inches. The rear blade type can be framed or beam-style, depending on the replacement you choose.
- Rear blade: 13 inches
When replacing the rear blade, ensure you select the correct attachment style (hook, pin, or bayonet) for the rear wiper arm on your exact model.

To confirm sizes, measure your current blades, check the packaging, and compare with the manufacturer’s specifications. Also verify the wiper arm attachment type (hook vs other styles) to ensure a proper fit.
Summary
For Jeep Wrangler JK front wipers, plan on 22 inches for the driver’s side and 21 inches for the passenger’s side, with a 13-inch blade for the rear window. Always verify by measuring or checking your owner’s manual, and choose the blade type (conventional vs beam) based on climate and driving conditions.
