Hi Kristine Cotterman,
Please use the following css to fix your issue:
.woocommerce ul.products li.product, .woocommerce-page ul.products li.product {
margin: 10px;
}
.woocommerce ul.products li.product a img {
width: 260px;
height: 260px;
}
Note: Please use the custom css plugin or child theme to write css.
Thanks
