Hi Antony! 

To resize your logo you'll need to first create a custom theme. You can do that by following our instructions on how to do so here. 

Once you've created your custom theme you'll be able to access the files that control the look and design of your site. You'll want to locate the file layout.html under Website> Site Name> Theme> Current Custom Theme> Templates.

You'll want to locate the line of HTML that appears as such: 

<header><a href="/"><img src="{{ site.meta_image_url }}"></a></header>

If you haven't made any customisations to your site previously, when using the Verve theme, this should be on line 77. 

You'll want to change the HTML of to read as follows: 

<header><a href="/"><img src="{{ site.meta_image_url }}" style="height:XXpx; width:XXpx"></a></header>

You'll want to replace XX with the correct pixel size. 

If you're still having trouble, email us with a link to your nation and site and we can help point you in the right direction.
