Angular Material mat-form-field set custom height

I have a couple of mat-form-field inputs with the following configuration:

<mat-form-field class="example-full-width" appearance="standard">
    <input type="number" matInput placeholder="PolĂ­gono">
</mat-form-field>

If I set the background color to red, I get the following result:

Background to red

As you can see, there is a huge bottom-top padding/margin size which I don’t need at all and that makes the input appearance not user-frendly.

How can I avoid this and make the input size attach only to the text area?

Adding css for reference:

.example-full-width {
    background-color: red;
    margin-right: 15px;
    width: 130px;
}

Thanks in advance.
