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 MINI Cooper, 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 | 530 mm / 21 in plus 500 mm / 20 in on the F65 and F66 petrol cars. The J01 electric car is a separate vehicle in the catalogue and its data is internally inconsistent — see the notes below the table. | Not resolved — see notes |
| Rear | F66: 240 mm / 9.5 in. J01: no data available. | Vehicle-specific rear fit |

Confidence in this data: F66 Medium; J01 Low — TecDoc data is internally inconsistent (450/484 bayonet vs 530 top lock vs 525 vs 510)
Checked against: Autodoc MINI F66/F65 and MINI Cooper J01
Model and body-style splits: The F65/F66 petrol car and the J01 electric car are separate vehicles in the catalogue with different data. Figures for one do not apply to the other.
- Caution: On earlier MINI hatch generations the passenger blade is the longer of the two. Do not assume the longer blade is the driver’s on this car — check both arms before ordering.
What Fitting Type?
Catalogue fitting for the MINI Cooper: F66: Top Lock (Valeo GEN2V). J01: conflicting — Valeo’s J01-specific set is Bayonet GEN2D, but most TecDoc entries against J01 are 530 mm Top Lock, which look like carry-over from the F-series body.
More than one arm interface is listed against this vehicle. That normally means a production-date or market change the catalogue has not dated. Do not buy on length alone — look at the connector on your own car first.
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 MINI Cooper 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. Release the blade at the connector. Because more than one arm type is catalogued for this car, check which connector yours actually has before you order.
- 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 MINI Cooper need?
Sources disagree for the MINI Cooper. 530 mm / 21 in plus 500 mm / 20 in on the F65 and F66 petrol cars. The J01 electric car is a separate vehicle in the catalogue and its data is internally inconsistent — see the notes below the table. Because the figures conflict, measure the blades on your own car before ordering.
What fitting type do MINI Cooper wipers use?
The MINI Cooper is catalogued as: F66: Top Lock (Valeo GEN2V). J01: conflicting — Valeo’s J01-specific set is Bayonet GEN2D, but most TecDoc entries against J01 are 530 mm Top Lock, which look like carry-over from the F-series body. 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 MINI Cooper take?
Rear blade for the MINI Cooper: F66: 240 mm / 9.5 in. J01: no data available. Rear blades are normally a moulded vehicle-specific fit, so match the part number rather than the length alone.
How often should I replace MINI Cooper 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 →
