Most recent Chevy Impala models use a 24-inch wiper on the driver’s side and a 19-inch blade on the passenger side. Exact sizes can vary by year and market, so you should verify against your vehicle’s manual or the blade packaging before purchasing replacement blades.
Understanding size variations by model year
Windshield wiper blade lengths are not universal across all Impala generations. While many 2014–2020 Impalas follow the 24"/19" pairing, older models and regional specifications can differ. Use the guidance below to confirm your specific year’s requirements.
Latest generation (2014–2020)
For the 2014–2020 Impala, the typical configuration is a 24-inch driver-side blade paired with a 19-inch passenger-side blade. This pairing aligns with other full-size GM sedans of the era, but regional market variations or trims may deviate. Always verify with your owner’s manual or current blades.
Earlier generations
Earlier Impalas varied more widely in blade lengths, and the exact sizes depend on the year and market. If you are replacing blades on an older model, check the owner’s manual, the blade packaging, or measure the current blades to determine the correct lengths. When shopping, bring the old blades or the measurements to ensure a proper fit.
How to confirm your exact wiper sizes
Use these steps to verify the precise blade lengths for your specific Impala model and year.
- Park the car and set the wipers to the service position so the blades are easily accessible.
- Check the blade itself for length markings on the spine or packaging if you still have the original packaging.
- If markings are not visible, measure each blade from tip to the end including the mounting area using a tape measure.
- Note the lengths for the driver and passenger sides; typical configurations will be indicated by the manual or the blade packaging when you replace both blades.
- Buy blades that match these measurements, or confirm with an auto parts store using your year, make, and model if you are unsure.
Following these steps will help ensure you get the correct blades that fit correctly and clear the windshield properly.
Summary
Windshield wiper sizes for the Chevy Impala vary by generation, with the most common modern configuration being 24 inches on the driver’s side and 19 inches on the passenger side for 2014–2020 models. Always verify against your vehicle’s manual or the blade packaging, or measure the current blades to confirm the right sizes before purchasing replacements. If in doubt, ask a dealer or parts specialist for your exact year and trim.
