Wiper blade sizes you’ll likely need

These are the standard measurements used by many fleets and aftermarket suppliers for this model, but some vehicles may differ depending on windshield assembly or optional equipment.
How to verify your exact size
To confirm the blade size precisely for your truck, use these verification steps.
- Inspect the existing blades for length markings (28" or 20" are common on this model).
- Consult Volvo's official parts catalog or your dealer service portal using the model year (2015), model (VNL 780), and VIN to pull the correct blade part numbers and lengths.
- Measure the blade length directly by removing the blade and measuring the entire blade from tip to base to account for any curvature or mounting style.
- Contact a Volvo Truck dealership or a trusted heavy-duty parts retailer if you’re unsure or if your vehicle has unusual equipment (e.g., atypical windshields or a single-beam setup).
Using the official parts diagram or precise measurement will ensure you buy the correct blades. Mismatched sizes can reduce wiping performance or create streaks.
