These two sizes are what most aftermarket sets provide for the Altima front wipers. If you purchase a two-blade set, ensure it includes a 26" blade for the driver side and a 17" blade for the passenger side.
Rear wiper blade size (if equipped)
Not all 2018 Altima models have a rear wiper. If yours does, the common size is:

Because some markets or trims may vary, always confirm the rear blade size by checking the owner's manual, the current blade itself, or the Nissan parts lookup for your exact VIN.
How to verify the right size and replace safely
To ensure you get the correct blades and install them properly, follow these steps: check the owner's manual or a parts diagram for your exact trim, measure the existing blades, use a reputable parts retailer’s compatibility tool, and follow the installation instructions provided with the blades. When replacing, avoid forcing blades into place and replace in pairs for the front to maintain even wiping performance.
