# Determine if an image is more or less landscape (or portrait) than given dimensions

Posted 2015-06-30 by cornbeast

Here’s a nifty c# extension method I wrote to determine how an image should be resized and/or cropped to fit within certain dimensions.

If you divide a rectangle’s width by it’s height you get a number representing the aspect. If both sides are equal you get 1. If the width is greater than the height you get a number that is more than 1, and if the height is greater you get a number less than 1.

```
public static bool IsMoreLandscapeThan(this Size size, Size compareSize){
float aspect = (float)size.Width / (float)size.Height;
float compareAspect = (float)compareSize.Width / (float)compareSize.Height;
return aspect > compareAspect;
}
```

Here’s how to use it:

```
if (originalImage.Size.IsMoreLandscapeThan(newSize))
{
//Do something
}
```
