Hi,

Please add this code to the Theme Settings > Custom CSS > Global:

div.quantity input[type="button"] {
    min-width: 5em !important;
}
div.quantity input[type="number"] {
    width: 5em !important;
}
.product-image-summary .single_add_to_cart_button{
	width: 200px !important
}

Change the code as per your need.

Best Regards.
