 ## How to Control the Size of the QR Code
 
 The size of the QR code is determined by the `QRCodeSettings.DotSize` and `QRCodeSettings.Version` properties. 
 
-The size determined through the `QRCodeSettings` will take precedence over the values set to the `Width` and `Height` properties of the main control tag.
+The size coming from the `QRCodeSettings` will take precedence over the values set to the `Width` and `Height` properties of the main control tag.
 
-Each integer increase increases the total size of the rendered image with a factor determined by the `Version` value. For example, with `Version="5"`, the factor is `45px`. Note that the function is not linear. If you want to determine exact sizes, the easiest way to see the exact size is to inspect the rendered PNG with the browser dev toolbar.

 For example, at `Version="5"`, `DotSize="1"` will result in a `45px` square, and a `DotSize="5"` will result in a `225px` square.

-If you set `DotSize="0"` the image will be rendered as if `DotSize="1"` (that is, a `45px` square at `Version="5"`), and the `<img>` element will get `height: 100%; width: 100%` CSS rules, so that it can stretch according to the `Width` and `Height` properties.

 When the image stretches because of `DotSize="0"`, it may get blurry. To always get a clear image, you can render it as a vector image, instead of the default raster image, by setting `OutputType="SVG_VML"`.
