# Configuring fill scaling
<a name="video-scaling-fill-ratio"></a>

If you choose **Fill** for your **Scaling behavior**, MediaConvert scales your input image until it fills the dimensions of your output resolution, and crops anything that exceeds the dimensions of your output resolution.

For example, if your input file is `200` pixels by `200` pixels and you want an output resolution that is `300` pixels by `400` pixels, MediaConvert increases the size of your input image to `400` pixels by `400` pixels, crops off the top and bottom `50` pixels, and returns a `300` pixel by `400` pixel file. MediaConvert does not add padding to your output when you choose **Fill**.

**Key**

The following key graphic shows input and output image width, height, cropping, and padding. In this key graphic, input dimensions (on the top and left) are in blue and output dimensions (on the right and bottom) are in red.

The following table shows example image scaling behavior when your input and output resolutions differ. For details about to read the images, reference the previous key graphic.
