@basscan : just checked on my iphone XR, the logo looks small-ish in portrait but very well pro-portioned in landscape
btw: have to tried to remove the logo and replace it with a different size/resolution version?
If you want to increase the size of the logo on mobile, try adding something like this to Customize > Additional CSS in your admin:
@media only screen and (max-width: 481px) {
.site-logo .custom-logo {
max-width: 170px;
}
}
You’ll want to test on a smaller phone to make sure the logo doesn’t overlap with the menu, though. If it does, you can try something smaller like 150px.
