Understanding the typical size and how to confirm it
The quick guideline: most Outbacks use an 11-inch rear blade. However, you should verify to avoid purchasing the wrong size.
Where to find the exact size
To confirm your exact size, check these reliable sources:

Using these sources will help you confirm whether your Outback uses the standard 11-inch blade or a different size for your year/model.
