The standard front-wiper blade sizes are typically 20 inches on the driver’s side and 18 inches on the passenger’s side; if your model has a rear wiper, it’s usually about 14 inches. Exact sizes can vary by cab configuration and trim, so verify before purchasing.
Front wiper blade sizes
Most 2013 Ram pickups use a 20-inch blade on the driver’s side and an 18-inch blade on the passenger side.
- Driver's side front blade: 20 inches
- Passenger side front blade: 18 inches
These sizes cover the majority of 2013 Ram 1500, 2500, and 3500 front assemblies; some trims or aftermarket replacements may differ by an inch or two.
Rear wiper blade size (if equipped)
Not all 2013 Ram models include a rear window wiper; for those that do, the blade is commonly 14 inches.
- Rear blade: 14 inches
Always check the manual or packaging to confirm if your cab and rear window require this size.
How to verify the exact size
Before purchasing blades, use these steps to confirm the right size and mount type for your specific truck:
- Inspect the current blades on both sides and measure their lengths (end-to-end along the blade).
- Consult the owner’s manual or the OEM parts catalog for the recommended sizes by year/model/cab configuration.
- Choose blades that match the length and mounting style (hook, pin, or hybrid) as specified by the manufacturer.
- When in doubt, bring the old blades or a model-specific part number to a parts counter or shop to ensure a proper fit.
Following these steps reduces the risk of buying blades that don’t fit your 2013 Ram.
Summary
Across 2013 Dodge Ram pickups, the typical front wipers are 20 inches on the driver’s side and 18 inches on the passenger’s side; rear wipers, if present, are usually 14 inches. Always verify against your exact cab configuration and check the manual or parts finder for the precise fit.
