Windscreen wiper sizes

[dcfb77]

I need to replace my wiped arms and remember seeing a thread on wiped arm sizes.

Sadly I can't find the thread anymore. Does anyone know the best sizes for the indiscreet.

If I remember right it was 20" amd 21"

yeah 20 and 21 is right,
original ones were 16 inch i think but dont seem to cover enough of the screen,

And the £1 shop ones are fine too - I change them about five times a year so buy five sets
