When you drive a BMW, you expect precision -- and that includes having clear visibility through every storm, snowfall, and slushy spring morning. Wiper blades may not be the most exciting part of your car, but they're one of the most important when it comes to safe, confident driving in Canada's unpredictable weather.

From the compact 3 Series to the all-electric i7, every BMW sedan has specific wiper blade sizes designed for maximum visibility and performance. Below, you'll find the correct measurements in centimetres for models from 2010 to 2025, including M variants and Gran Coupes. Whether you're prepping for winter or refreshing your blades after a tough season, having the right fit ensures a safer, clearer drive year-round.

Why Wiper Blades Matter More Than You Think

In Ottawa and Gatineau, we see everything from sleet to sun to sudden spring rainstorms -- often in the same week. Your wipers are your first line of defence for visibility. Over time, the rubber degrades due to heat, UV rays, road grime, and salt. When that happens, blades start skipping, squeaking, or leaving streaks behind.

Worn blades can:

• Reduce visibility, especially during night driving or heavy rain
• Miss key areas of your windshield
• Increase glare from streetlights or oncoming traffic
• Even scratch your windshield if the rubber peels away

Replacing your blades is fast, affordable, and essential for safe driving year-round.

When to Replace Your Wipers

Most drivers should replace their blades every 6 to 12 months, depending on how often you drive and how tough the weather is. In a climate like ours, swapping them out before winter and again after spring thaw is a smart habit.

Need a sign it's time? Look (and listen) for:

• Squeaking or skipping across the windshield
• Visible tears, cracks, or warping in the rubber
• Streaking or patchy wiping
• Reduced visibility during a storm
