Windshield Wiper Size Calculator
Find wiper blade sizes for driver, passenger, and rear positions from vehicle year, make, and model.
Covers hook, pinch-tab, and side-pin connection types.
Windshield wiper replacement intervals are determined by the degradation of the rubber wiper blade, which is caused by UV exposure, temperature extremes, ozone, and physical abrasion. A wiper that leaves streaks, skips, chatters, or squeaks needs replacement — regardless of how much time has passed.
General replacement guideline:
Replacement Interval = 6 to 12 months (standard rubber blades)
Replacement Interval = 12 to 24 months (silicone or beam blades)
In regions with extreme heat, UV, or heavy rain/snow, lean toward the shorter end of these ranges.
Degradation scoring — a practical inspection guide:
Inspect each blade on four criteria (score 0 = none, 1 = minor, 2 = severe):
- Streaking: water smeared across glass after each pass
- Skipping: blade bouncing or chattering across glass
- Edge cracking: visible deterioration of the rubber contact edge
- Frame corrosion: rust or bend in the wiper arm/frame
Replacement Score = Sum of criteria scores
- 0–2: Acceptable, monitor at next service
- 3–5: Replacement recommended soon
- 6–8: Replace immediately: safety risk
Blade type comparison:
| Type | Lifespan | All-Weather | Snow Performance | Price |
|---|---|---|---|---|
| Traditional (frame) | 6–12 mo | Moderate | Poor | $8–$18 |
| Beam (bracketless) | 12–24 mo | Good | Good | $20–$40 |
| Hybrid | 12–18 mo | Excellent | Excellent | $18–$35 |
| Silicone | 18–30 mo | Excellent | Excellent | $25–$50 |
Wiper size note: Driver and passenger blades are almost always different lengths. Always check your vehicle’s specific sizing in the owner’s manual or a parts store fitment guide — installing the wrong size can leave uncleaned zones or damage the motor.
Rear wiper: If your vehicle has one, replace it simultaneously — it endures similar wear.
