How to choose the right wiper blades
In short
Measure the two blades separately, because the driver's and passenger's side are almost always different lengths, and replace them roughly once a year or as soon as they start to streak. Flat beam blades cope best with winter and high speeds, frame blades remain the cheapest option, and hybrids sit between the two.
The three types of blade
Classic frame blades are built around an articulated metal skeleton that spreads the arm's pressure across the rubber strip at several points. They are the cheapest option and work well on strongly curved windscreens. Their weakness shows in winter: the joints pack with snow and ice, the frame freezes, and the rubber stops following the glass, leaving unswept patches. Flat blades, also called frameless or beam blades, contain a pre-curved spring steel strip shaped to the windscreen. There are no joints to freeze, pressure is more even across the whole length, and an aerodynamic profile keeps them pressed to the glass at speed. They are the preferred choice for winter and for long journeys. Hybrid blades combine a short frame enclosed in an aerodynamic plastic shell. They are heavier but very quiet and durable, and many cars leave the factory fitted with this type. There is no universally superior type. What matters is the windscreen curvature, the arm design and how you use the car.
How to measure the length correctly
You measure the blade, not the arm. Take a tape measure and measure the existing blade end to end across its working length, then round to the nearest standard size — blades are generally produced in 5 centimetre steps. The most important detail: the two front blades are almost always different lengths. The difference may be 5 cm, but it can also be 15 cm. The reason is the wipe geometry: the driver's blade sweeps a larger area, while the passenger's must be shorter so that it does not strike the pillar or the other blade at the end of its travel. Do not fit two identical blades simply because it is easier to buy: an overlong blade on the passenger side can catch, bend the arm or run off the edge of the glass. Many blades have the size printed on the plastic end cap or on the back of the spoiler. If the car still wears its original blades, that is the most reliable source. The quickest alternative remains looking them up by make, model and year.
The fitting: the part people get wrong
The right length is no help if the blade will not attach to the arm. The hook fitting remains the most widespread, in two main sizes, but cars from the last fifteen years increasingly use proprietary designs: push button, with a button on the top face; side pin; bayonet; pinch tab; top lock and others. For that reason, most decent universal blades come with a set of adapters in the box, while model-specific blades arrive with the correct adapter already fitted. Check the list of fittings on the packaging before buying. The simplest way to avoid a mistake: photograph the end of the wiper arm with the blade removed, from the side and from above, and send the pictures along with the make and model.

When removing a blade, make sure the arm does not fall onto the glass — a bare metal arm can crack a windscreen. Lay a thick cloth underneath while you work.
How long they last and when to replace
A wiper blade wears out mainly from its environment rather than from wiping rain. Ultraviolet light and ozone harden the rubber, dust on the glass acts as a fine abrasive, and ice and scrapers tear the working edge. A car parked permanently in the sun wears blades faster than one kept in a garage, even if it covers fewer kilometres. In practice, a realistic life is 6–12 months, and replacing them once a year in autumn, before the rainy season and winter, sets a good rhythm. Signs that their time is up: streaks left behind after each pass, unswept areas at the edge of the sweep, squealing or juddering (the blade twisting instead of gliding), a cracked or torn rubber edge, or a blade that lifts off the glass at speed. Replace both at once. If one has failed, the other is the same age with the same exposure, and the difference in performance on the passenger side shows immediately.
Care: how to make them last
Wipe the rubber edge with a cloth dampened in washer fluid or isopropyl alcohol once a month. You will be surprised how much dirt comes off, and the improvement in wipe quality is immediate. Never switch on blades that are frozen to the glass. Thaw the windscreen with the blower and a de-icer, then check by hand that the blade moves freely. Forcing them tears the rubber edge and can destroy the motor or the linkage. In winter, if you park outdoors, lift the arms or lay a cover over the windscreen. Lifting only helps while they are not yet frozen down — otherwise you are simply straining the spring. Do not wipe a dry, dusty windscreen. Apply fluid first, or the dust scratches both the rubber and the glass. If new blades still streak, the problem is the glass rather than the blade: a windscreen coated with tree resin, car-wash wax or a greasy film needs cleaning with a dedicated glass product. Check the arm spring tension as well — a tired arm no longer presses hard enough, and the blade lifts at speed.
The rear blade, the one everyone forgets
On estates, hatchbacks and SUVs the rear wiper works less often but in dirtier conditions: the rear screen collects everything the car throws up from the road, and in winter that is where salt and grime settle most. It usually has a completely different fitting from the front blades and is much shorter, so it has to be ordered separately by car model. On many cars only the rubber strip is replaced, on others the whole assembly. It is worth checking every time you replace the front blades. A worn rear blade leaves a hazy film exactly in the field of view you rely on when reversing and changing lanes. Check the rear washer nozzle too: it clogs frequently, and wiping dry destroys a blade within weeks. The same rules apply to headlight washers where fitted.

Frequently asked questions
Can I fit two blades of the same length at the front?
Usually not. The two sides have different wipe geometry, and an overlong blade on the passenger side can strike the pillar or the other blade. Measure each blade separately.
Are flat blades better than frame blades?
In winter and at high speed, usually yes, because they have no joints to freeze and press more evenly. On strongly curved windscreens or on a tight budget, a good frame blade remains a sensible solution.
How often should wiper blades be replaced?
As a guide, once a year, or sooner if they streak, judder, squeal or the rubber edge has cracked. Sun and dust age them even when the car covers little distance.
My new blades still streak. Why?
Most often the windscreen is the culprit, carrying tree resin, wax or a greasy film. Clean the glass with a dedicated product and check the spring tension in the wiper arm.
