When you ordered two sizes and want to return the one that doesn’t fit, you don’t need to overthink it—Amazon already expects this kind of situation.

What to select when returning

When you go through the return process, just choose one of these common options:

  • “Too small” (if it didn’t fit)
  • “Too large”
  • “Better price available” (less accurate, but sometimes used)
  • “Ordered multiple sizes/colors” (this is the most accurate if available)

What to write (if there’s a comment box)

You can keep it simple. For example:

“I ordered two sizes to compare and am returning the one that didn’t fit.”

That’s perfectly normal and accepted.

Quick tip

Amazon actually encourages ordering multiple sizes for things like clothes or shoes, so:

  • You won’t get in trouble for returning one
  • Just make sure it’s unused and in original condition

If you want, tell me what item you ordered—I can suggest the exact best return reason option for it.
