Wiper Blade Sizes at a Glance
Blades are labelled by length, not by side: supplier catalogues do not state which of the two front blades belongs on a right-hand-drive car’s driver arm.
Wiper Blade Sizes
Front blade lengths and arm fitting for the Fiat 500, taken from the Bosch and Valeo entries in the TecDoc-derived parts catalogue. Catalogues publish a front set as two lengths and do not state which blade belongs on the driver’s arm of a right-hand-drive car, so this table labels the blades by length rather than by side. Measure the blade you are replacing, or check both arms, before you order.
| Position | Blade length | Arm fitting |
|---|---|---|
| Front pair | This page covers two different cars. Fiat 500 Hybrid (series 312): 600 mm / 24 in plus a shorter blade given as either 340 mm / 13 in (Bosch conventional kit) or 350 mm / 14 in (Bosch Aerofit set and Valeo VSF35) — the sources disagree. Fiat 500e (series 332): 600 mm / 24 in plus 340 mm / 13 in (Bosch) or 350 mm / 14 in (Valeo) — again disputed. | Hook (9×3 / 9×4) |
| Rear | 312: no data available. 332: 280 mm / 11 in, established only by a Quinton Hazell listing (QDR100) — no Bosch or Valeo rear listed. | Vehicle-specific rear fit |
Recommended Wiper Blades for 500

Confidence in this data: Medium — passenger length disputed on both
Checked against: Autodoc 500 312 and 500e 332
Model and body-style splits: The 500 Hybrid (312) and the 500e (332) are different cars with different arms and different parts, and are given separately above. The 500C convertible (312) and the New 500 Convertible (332) are further separate entries that have not been checked.
What Fitting Type?
Catalogue fitting for the Fiat 500: Different on each car, and not interchangeable. The 500 Hybrid (312) uses a standard 9×3 / 9×4 hook arm. The 500e (332) uses a Top Lock arm. Check which car you have before ordering — a blade for one will not fit the other.
Adapter warning. The Bosch set listed for this car is an Aerotwin Original (A-prefix). Aerotwin Originals ship with a single moulded, vehicle-specific adapter — they are not multi-fit and will not clip onto a different arm type. Bosch’s multi-fit products are the Aerotwin Retrofit (AR-prefix) and Aerotwin Plus (AP-prefix) ranges.
Right-hand drive. The sets catalogued for this vehicle are flagged for left-hand-drive cars and no right-hand-drive equivalent was found in the data we checked. That is a gap in the catalogue rather than proof the part is wrong for a UK car — confirm with the supplier or a dealer parts desk before buying.
Fit blades in pairs. Both front blades age at the same rate, so replacing only the streaking one usually means doing the other within weeks.

How to Replace Wiper Blades
Changing the front blades on the Fiat 500 takes a few minutes and needs no tools.
- Lift the arm away from the glass until it locks upright, and lay a folded cloth on the screen in case it drops.
- Release the old blade. Slide the blade down towards the base of the arm, then unhook the J-hook from the blade’s bridge and lift the blade clear.
- Compare old and new side by side before fitting — same length, same connector. If the adapter does not match, stop; forcing it damages the arm.
- Fit the new blade until the catch clicks home, then tug it gently to confirm it is locked.
- Lower the arm back to the glass by hand. Repeat on the other side, then test with plenty of washer fluid on a wet screen.
Never let a bare arm snap back onto the glass — a windscreen chipped that way is not covered by the blade warranty.
When to Replace Your Wipers
Wiper rubber hardens with UV and heat rather than with mileage, so a set on a car that is parked outside will usually be finished in about 12 months whatever the distance covered. Replace them when you see any of the following:
- Streaks or a haze left behind on the return sweep
- Juddering or chattering across the glass
- Missed strips of screen, especially at the top of the sweep
- Splits, curling or a shiny, glazed edge on the rubber
- Squealing that does not clear with a wash and a wipe of the rubber
Clean the rubber with a damp cloth every few weeks and clear leaves and grit from the base of the screen; both add months to a set. A blade that still streaks after cleaning is worn, not dirty.
Frequently Asked Questions
What size wiper blades does a Fiat 500 need?
Sources disagree for the Fiat 500. This page covers two different cars. Fiat 500 Hybrid (series 312): 600 mm / 24 in plus a shorter blade given as either 340 mm / 13 in (Bosch conventional kit) or 350 mm / 14 in (Bosch Aerofit set and Valeo VSF35) — the sources disagree. Fiat 500e (series 332): 600 mm / 24 in plus 340 mm / 13 in (Bosch) or 350 mm / 14 in (Valeo) — again disputed. Because the figures conflict, measure the blades on your own car before ordering.
What fitting type do Fiat 500 wipers use?
The Fiat 500 is catalogued as: Different on each car, and not interchangeable. The 500 Hybrid (312) uses a standard 9×3 / 9×4 hook arm. The 500e (332) uses a Top Lock arm. Check which car you have before ordering — a blade for one will not fit the other. Note that Bosch Aerotwin Original (A-prefix) sets carry one moulded, vehicle-specific adapter and are not multi-fit.
What rear wiper blade does a Fiat 500 take?
Rear blade for the Fiat 500: 312: no data available. 332: 280 mm / 11 in, established only by a Quinton Hazell listing (QDR100) — no Bosch or Valeo rear listed. Rear blades are normally a moulded vehicle-specific fit, so match the part number rather than the length alone.
How often should I replace Fiat 500 wiper blades?
About once a year for most UK cars. Wiper rubber degrades with UV, heat and grit rather than with mileage, so a car parked outside will need blades sooner than the distance covered suggests. Replace them as soon as they streak, judder or miss part of the sweep after cleaning.
How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
