Hello,
As there are three default sizes for those filter images as “Small, Medium and Large” and you already selected the large one from the widgets and now you want to increase the size more than the large size.
So to do this you can use the below CSS in Theme Settings >> Custom CSS >> Custom Global CSS:
.woodmart-pf-dropdown .swatches-large .filter-swatch>span, .woodmart-woocommerce-layered-nav .swatches-large .filter-swatch>span {
width: 50px;
height: 50px;
}
I used 50px just to set an example for you. You can use another size. But remember that height and width size must be the same otherwise the circle shape will be destroyed.

But remember that this code might also increase the image size of the other filters in some situations. So it’s up to you that you used this custom CSS code or not.
Best Regards.
