Hello @webpat,
If you are using a pre-built single product page, you can adjust the size of the social sharing icons on the page by using the Custom CSS code. Please copy and paste the following CSS code into XStore >> Theme Options >> Theme Custom CSS >> Global CSS and then clear your browser cache.
.single-product ul.menu-social-icons li a.title-toolip {
font-size: 25px !important;
}
You may adjust the font size according to your needs.
The result should look like this: https://postimg.cc/KkY8Ppb5
We hope this will solve your issue.
Best Regards,
