Wiper blades: Maintenance and replacement

You must replace the wiper blades on your car with the same size.

When people talk about windscreen wiper size, they usually mean wiper blade size, the blade being the removable strip that connects to the arm and makes contact with the windscreen.

Windshield wiper blade sizes are measured in millimetres or inches, which refers to the length of the blade.

There is a range of wiper blades available, in sizes from 9" to 32" or 250mm through to 813mm. If you replace your wiper blades with smaller blades, they won't cover the entire windscreen, leaving gaps.

Use wiper blades that are too big, and they will wear out more quickly. Any rubber left dangling at the end of the wiper can become tangled or damaged.

Through our WeFit service, we can change your wiper blades for you, but before this, you will need to find the correct wiper blade size. 

Finding the correct wiper blade size couldn’t be easier thanks to our vehicle registration number tool. Just enter your registration number and it will display the correct wiper blade size for your vehicle. If you don’t know your registration, you can use the search criteria to help find your vehicle model. Once you have this information, you can head over to Halford’s wide selection of wiper blades. You can also find the wiper blade size in your vehicle’s owner’s manual. If you do not have a manual copy of this, it can often be found online.

Additionally, if you remove the wiper blade itself, there may be some manufacturer’s marks either indicating the model or size of the blade, ideal if you’re keen to purchase the exact same blade.

It is also possible to manually measure your wiper blade size by simply pulling your wiper arm away from your windscreen and using a tape measure, but we would always advise you to make certain through our Halford’s vehicle registration number tool. 

You must regularly check your windscreen wipers and replace the blades if they're damaged or missing.

Regular maintenance – like cleaning and repositioning – can extend the life of your windscreen wipers to avoid more frequent replacements and save you money. You can read more about windscreen wiper maintenance here.

Through our road-ready car check, we can conduct a 10 point check of your car, including the condition of your wiper blades.

In general, if you can see or feel any damage on the blades, you should replace them. While a windscreen wiper check is included in your service and is part of every MOT test, we recommend that drivers check their wiper blades every couple of months, or immediately if they experience any problems while driving. 

Buying cheap wiper blades is a false economy, with inferior-quality parts wearing out more quickly than high-quality replacements. We stock our own tried and trusted range of Halford's windscreen wiper blades alongside Bosch wiper blades

We also have a new range of silicone blades available which are exclusive to Halfords. More resilient to heat, cold and UV rays, these blades last twice as long as standard rubber wiper blades.

If you want to take away the hassle of changing your wiper blades yourself, we can fit your blades for you through our WeFit service.

Our click and collect and home delivery services also make it simple to pick up the parts you need and you can find more information on how to fit your new wiper blades in our advice guide.
