Are square textures a requirement?

Unity Engine

Hello everybody,

Was unable to find a definitive answer for this.
I know textures should be in a power of two dimensions, and I understand older iOS devices limit to 1024x1024 whereas newer devices allow 2048x2048.

Now, must these textures be square?
I mean, if I have a narrow strip of an image, say 1024x64 pixels - will it be converted to 1024x1024 by Unity?

You need to be square, power-of-2 if you use compression. You don’t have to use either if you don’t use a compressed texture format.
