The minimum height of the University of Lethbridge logo should be 1” (25mm). NEVER go smaller than this. If the space you have is smaller than this, then the application medium is unsuitable.
The logo does not have a maximum reproduction size.

The logo should always be situated in a clear, readable location. The logo must always have good contrast with the background to ensure maximum impact and accessibility.
