The most common front-wiper sizes for the 2018 Ford Transit Custom are 26 inches on the driver's side and 16 inches on the passenger side. If your van has a rear wiper, the rear blade is typically 12 inches. Market or trim differences can apply, so always verify against your vehicle's documentation or current blades.
This article breaks down the standard sizes and how to confirm the correct blades for your exact vehicle configuration, including notes on rear wipers and how to check the measured length before purchasing replacements.
Front wiper blade sizes
The front blades come as a pair with two different lengths. Use the following as a guideline for most 2018 Transit Custom models.
- Driver-side blade: 26 inches
- Passenger-side blade: 16 inches
These specifications cover the majority of 2018 Transit Custom variants in Europe and similar markets; always double-check the length stamped on your current blades or in the owner's manual.
Rear wiper blade (if fitted)
Some Transit Custom configurations include a rear wiper. If your van has one, expect a 12-inch blade. Not all models include a rear wiper, so this may not apply to your vehicle.
How to confirm the correct size
Before buying replacements, use these quick verification steps to ensure you get the right length and fit.
- Check your current blades for length markings or measurements.
- Consult the owner's manual or Ford's official parts catalog by vehicle VIN/market to confirm blade size.
- Measure the blade physically from tip to tip if you are unsure.
Accurate confirmation helps avoid purchasing the wrong size and ensures proper wipe coverage and safety.
Summary
For a 2018 Ford Transit Custom, prepare 26-inch driver-side front wiper blades and 16-inch passenger-side front blades. If a rear wiper is present, plan for a 12-inch rear blade. Market variations exist, so verify with the manual or a parts catalog before buying.
