Answer 1

You can use this ( .mat-checkbox-inner-container ) CSS class to modify the mat-checkbox
.mat-checkbox-inner-container {
height: 50px!important;
width: 50px!important;
}
Note that you need to put the style modification in styles.css root folder (
/src/styles.css ) and not in the components css.
Also put !important ( width: 50px!important; ) to override the
default style.
Below is the default style for the mat-checkbox
.mat-checkbox-inner-container {
display: inline-block;
height: 20px;
line-height: 0;
margin: auto;
margin-right: 8px;
order: 0;
position: relative;
vertical-align: middle;
white-space: nowrap;
width: 20px;
flex-shrink: 0;
}
Hope this helps.

If you want to change color then use these in your CSS file
::ng-deep .mat-checkbox .mat-checkbox-frame {
border-color: black;
}
::ng-deep .mat-checkbox-checked .mat-checkbox-background {
background-color: black !important;
}

Answer 3

::ng-deep .mat-checkbox-checkmark-path {
stroke: #000 !important;
}
Hope this css will resolve your issue

Answer 4

to change styles use classes and define them in your scss component file.
When you see that this not work's, use the selectors :host /deep/ before the class name in each of the scss defined classes.
The size of the icons is defined by the font-size not width / height

In my project, we overrode sizes of checkboxes and radio buttons to 16px in this way:
body .mat-checkbox-inner-container, body .mat-radio-container, body .mat-radio-outer-circle, body .mat-radio-inner-circle {
height: 16px;
width: 16px;
}
body .mat-checkbox-ripple, body .mat-radio-ripple {
left: calc(50% - 20px);
top: calc(50% - 20px);
height: 40px;
width: 40px;
border-radius: 50%;
}
