Hi Fruity_Vruity ,
Welcome to the forums! 🥳
You can use a custom CSS to change the size of the buttons.
Copy and paste this into WordPress' Additional CSS in Customize:
/* GROUP BUTTON */
.buttonizer .buttonizer-button.buttonizer-head {
width: 56px;
height: 56px
}
/* SUB BUTTONS */
.buttonizer .buttonizer-button-list .buttonizer-button
{
width: 40px !important;
height: 40px !important;
}
