gen 5 takes a 24" & 19"
ive tried just about everything on the market and im extremely picky
for good value go with teflon shield blades... the design is almost identical to the new style hybrid blades on most new cars including toyota's
i do recommend a higher quality blade though..... they cost more up front but will perform better and last longer
i would highly recommend bosch icon or valeo 900 series..... they both last a long time and perform very well.... i would slightly prefer the bosch blades because of the looks and they are more availble but the valeo's can be cheaper if u get them on sale
however the best blades ive used so far is OEM toyota hybrid blades..... these can be found on newer toyota's like gen 6 camry, gen 3 prius, gen 3 sienna, ect; perform exellent and have a low profile streamline design that looks great
they are very expensive, however they last a very long time and you can buy rubber refills from the dealer; i have customers come in all the time with original toyota hybrid blades and the car is easily over 3 years old so they are well made
