Default Re: Does upsizing wiper blades really help?

Standard size on my ecosport is 22" & 16" and I have been using 24" & 16", with no issues. Slightly more coverage on the driver side is the benefit. One size more and both the wipers will hit each other.

Nice application of elementary physics, the only assumption I am not comfortable here is quoted above; material conformability ties in with the selection of the rubber too, and its mechanical properties that follow.

The theory works if we assume that the bigger size blades exert the same force on the spring as the OEM ones. As per Mr. Newton, every action = equal and opposite reaction, so if bigger size blades exert more force on spring, then spring too exerts equal force on it. This goes on until the spring breaks or looses its natural stiffness.

@Anurag
You can definitely go for a size bigger, ample of room to go for a bigger wiper on the ertiga. Since you have the creta you could just swap and check and take a call.

Could you please link us to your tried and tested product? Thanks in advance!

I always have two sets of wiper blades. I fix the best one before the onset of the monsoon (in the month of June) and change it with the other one in the month of December. When the rubber becomes hard, I go for a new pair and always stick to OEM size.

Non availability! My First gen Ford figo has a 10 inch wiper blade as rear wiper. I searched a lot, but couldn't source a good wiper in that dimension. So upgraded to 12" and is happy with the extra sweep area.

Very valid arguments put up by everyone. It could be that the stock size seemed inadequate for me. As someone who doesn't want to overspend on a consumable item especially in a dry and hot climate which accelerates deterioration of rubber, I have been using upsized blades since the last 3 years on my Duster.

A few other reasons I could think of:
- Misleading info available online
Does upsizing wiper blades really help?-offer.jpg
Online sellers have 24"(D)/21"(P) set shown as a compatible set for my car which has the stock size of 20"(D)/20"(P). It might be the only car which has equal length blades (except for old Jeeps), which is an odd combo leading to the next reason...
- Upsized combo usually priced better
An upsized set of blades is available for 300-400 bucks for my car whereas the stock set is not only difficult to find in the listings, it is also more expensive in most cases. The stock set from the costs 1,400 bucks from the ASC and ~ 600 bucks outside.
- Dashcam and sticker coverage

Although I wasn't a victim of this, but some users might feel the need to upsize in order to sweep over the dashcam. With the increase in number of dashcam users, it is hard to ignore the need for better windshield coverage. It also helps sweep over stickers which I need to keep clean for the sake of pointing out to them to concerned persons.
If you see the sweep pattern above, my co-passengers, usually my wife is not very happy with it even after the upsize, due to the dirty unswept area (top left corner when viewing from inside) being directly in her field of vision.

Apologies for the delay. I somehow missed your quoted post.
This is the one I have.
