Increasing the size of a bootstrap checkbox

javascript css bootstrap-4 bootstrap-5

I am creating a simple check box with the code from the official bootstrap documentation:

<div class="custom-control custom-checkbox">
    <input type="checkbox" class="custom-control-input" id="customCheck" name="example1">
    <label class="custom-control-label" for="customCheck">Check this custom checkbox</label>
</div>

I am wondering how to make the checkbox larger than it currently is? I have tried editing the css of customCheck and changing the height and width properties, but that does not increase the size of the box.

I added classes like *-sm, *-md, *-lg, *-xl for the bootstrap switch.

Here I made all resolutions switch with one @mixin ( @mixin is very similar to JS functions but it does not return anything ).

For Bootstrap 4

custom-switch-sm, custom-switch-md, custom-switch-lg, custom-switch-xl
