Wiper Blade Size Guide Calculator
Find the correct wiper blade size for your vehicle.
Learn how to measure wiper blades and choose the right replacement type.
Wiper blades are one of the most important safety items on a vehicle, yet one of the most neglected. Worn or wrong-sized wiper blades cause streaking, skipping, and poor visibility — all of which are dangerous in rain, snow, or fog.
How to Measure Your Wiper Blades
If you don’t know your wiper sizes, measure them directly:
- Lift the wiper arm away from the windshield until it locks in the raised position
- Measure the full length of the rubber blade (not the arm) from tip to tip
- Note the sizes for both driver and passenger sides — they are almost always different lengths
Most cars have the driver-side wiper longer than the passenger side. Some vehicles have a rear wiper with a third, shorter blade.
Common Wiper Sizes
| Vehicle Type | Driver Side | Passenger Side |
|---|---|---|
| Compact car | 22–24 in (55–60 cm) | 16–18 in (40–45 cm) |
| Mid-size sedan | 24–26 in (60–65 cm) | 16–20 in (40–50 cm) |
| SUV / Crossover | 24–28 in (60–70 cm) | 18–22 in (45–55 cm) |
| Truck | 20–24 in (50–60 cm) | 18–20 in (45–50 cm) |
Blade Types
| Type | Description | Best For |
|---|---|---|
| Traditional (framed) | Metal frame holds rubber blade | Most weather conditions |
| Beam (bracketless) | One-piece curved design, no frame | Snow, ice, cleaner look |
| Hybrid | Solid outer shell, rubber blade inside | All-weather performance |
| Winter | Heavy rubber cover, resists ice/snow packing | Cold climates |
When to Replace Wiper Blades
Replace wiper blades every 6–12 months, or immediately if you notice:
- Streaking — leaving bands of water
- Skipping or chattering noise
- Squealing
- Blade lifting at high speeds
- Visible cracks or tears in the rubber
Installation Tips
Always replace both wiper blades at the same time — they wear at the same rate. Check the connection type (hook, pinch tab, pin, or bayonet) before buying, as not all blades fit all arms. Many auto parts stores will install them for free.
Wiper Fluid
Change your wiper fluid seasonally. In winter, use fluid rated for −20°C (−4°F) or lower. In summer, use a formula with insect remover. Never use plain water — it doesn’t contain surfactants, can freeze, and promotes mineral buildup on the windshield.
