The front wiper blades for the 2018 BMW 5 Series are 26 inches on the driver’s side and 20 inches on the passenger side. The sedan variant does not have a rear wiper; if you own a Touring (estate) variant, rear blade sizing can vary and should be checked in the owner’s manual.
Overview of wiper blade sizing for the 2018 BMW 5 Series
Understanding the correct blade lengths helps ensure full windshield coverage and proper park positioning. The 2018 5 Series (G30) uses distinct lengths for the driver and passenger sides, and there are market or trim variations to consider. Below is a clear breakdown to guide replacement decisions and prevent fitting issues.
Front wiper blade sizes
To ensure proper fitment and optimal wipe quality, the following lengths are standard for the 2018 BMW 5 Series front blades:
- Driver's side: 26 inches
- Passenger's side: 20 inches
Note that aftermarket replacements may offer slight length variations (for example 25.5" or 26" on the driver side, and 19"–21" on the passenger side) depending on the blade model and connector type. Always verify compatibility with your specific blade and vehicle configuration before purchasing.
Rear wiper considerations
The 2018 BMW 5 Series sedan does not include a rear wiper. If you drive a Touring (estate) variant or operate in a market where a rear wiper is fitted, check the owner’s manual or parts catalog for the exact rear blade size, as it can differ by model year and market.
Shopping and replacement tips
When selecting blades, weigh factors such as climate, winter performance, and blade material. Common choices include OEM-equivalent blades and well-known aftermarket brands. Ensure you match the correct connector type (hook, pin, or side-mmount) and confirm fitment using the blade model’s compatibility guide.
After installing new blades, run the washer cycle to check contact and coverage across the windshield. If streaking or skipping occurs, consider trying a different brand or a winter-rated blade for colder climates.
Summary
For the 2018 BMW 5 Series, plan on 26-inch blades on the driver’s side and 20-inch blades on the passenger side for the front. The sedan generally lacks a rear wiper; if you have a Touring variant, verify the rear blade size from the manual or parts catalog. Always confirm fitment with your specific model year, market, and blade type before purchasing, and consider winter-rated options if you live in freezing conditions.
