The front wiper blades for a 2019 Kia Optima are typically 24 inches on the driver’s side and 18 inches on the passenger side, with an 11-inch blade for the rear window if your car has a rear wiper.
These sizes cover the standard setup for most 2019 Optima sedans. Wiper configurations can vary by market and trim, so it’s wise to confirm against your owner’s manual or a parts retailer using your VIN or current blade style.
Front and rear blade sizes
Use the sizes below as the baseline for replacing blades on a typical 2019 Optima. If you're unsure, measure the blade you remove or check the vehicle's documentation.
- Driver-side front blade: 24 inches
- Passenger-side front blade: 18 inches
- Rear blade: 11 inches (if equipped with a rear wiper)
Front and rear wiper sizes for the 2019 Optima generally align with these lengths, ensuring full windshield coverage and effective clearing in wet conditions.
Replacement tips
When buying replacements, consider quality beam blades for better contact and durability. Ensure you select the correct lengths for each side and verify connector compatibility with your wiper arms.
- Choose blades that are designed for your vehicle model; some aftermarket blades require adapters or specific connector types.
- Replace blades in pairs on the front to maintain even wiping performance, or replace the worn blade at minimum to avoid streaks.
- Inspect wiper arms for stiffness or damage, since damaged arms can reduce blade effectiveness.
By confirming the exact sizes and installing compatible blades, you’ll maintain clear visibility through rain and snow.
Note: For an exact part number, check Kia’s official parts catalog or ask a trusted retailer with your VIN, as some markets may have slight variations.
Why correct sizes matter
Using the correct blade sizes ensures full coverage of the windshield, minimizes streaking, and improves safe visibility during adverse weather.
Summary: For a 2019 Kia Optima, plan on 24-inch driver-side front blade, 18-inch passenger-side front blade, and an 11-inch rear blade if your model has a rear wiper. Always verify with your owner’s manual or a parts retailer for your exact configuration.
