+### Uses an enhanced method to calculate the width/height values when clicking Aspect Ratio buttons.
+
+- Gets the mean value (average) of the current **width** and **height** values in the UI.
+- For the selected aspect ratio, the dimensions are offset equally (positively and negatively) from the average, ensuring nearest total pixel count to user's initial resolution.
+- Uses the same precision rounding method as [Stability-AI/StableSwarmUI](https://github.com/Stability-AI/StableSwarmUI/blob/4ef98019fc4796d69f0d1d2dfa487d684a748cc3/src/Utils/Utilities.cs#L573) when updating image dimensions.
+
+### For ideal and consistent results, first click a static 1:1 resolution value (such as 1024 x 1024, 512 x 512, etc)
