Measure the old blade along the rubber, from one end to the other, and round to the nearest inch. Wiper blades are sold in inches. Most cars take two different lengths at the front, so measure each front blade on its own and the rear blade too.
What you need
A tape measure. The blades can stay on the car while you measure them.
Step by step
- Lift the wiper arm away from the windscreen until it stays up by itself. Lay a towel on the glass underneath in case the arm springs back.
- Hold the tape against the rubber and measure from the tip at one end to the tip at the other. Measure the blade, not the metal arm.
- Round to the nearest whole inch. A blade that measures 60.5 cm is a 24 inch blade.
- Measure the passenger side blade as well. The driver's blade is usually the longer one, but some cars use two blades of the same length.
- If your car has a rear wiper, measure that blade too. Most rear blades we sell are between 11 and 16 inches.
- Look at where the blade joins the arm and note the fitting. Our guide to wiper fitting types shows how to tell them apart.
Wiper blade sizes in inches and centimetres
Blade makers round their metric sizes, so a 24 inch blade can be listed as 600 mm or 610 mm. Use the inch size to compare.

Mistakes that lead to the wrong size
Measure the rubber, not the arm. The arm is longer than the blade and gives a size that does not exist for your car.
Do not assume both front blades are the same length. Check each one.
The model name alone is not enough either. The same model can change blade sizes between generations and body styles, and a left-hand-drive import can use different lengths from a UK car of the same year.
FAQ
Can I fit a longer or shorter blade than the original?
Stay with the original lengths. A longer blade can catch the windscreen trim or the other blade, and a shorter one leaves part of the screen unwiped.
Do flat blades and traditional blades measure the same?
Yes. Measure the rubber from end to end whatever the blade looks like.
Can I find my sizes without measuring?
Yes. Find your car on our shop by car page. Every listing shows the lengths and the fitting for that model, years and body style. Or email info@wipewave.co.uk with your registration and we will check it for you.
