How can I change size of main logo?

HI mate,

My coder checked your site also.
Your image has too much detail. So when uploading the image, the width of the image is the fixed size, but the length will be pulled based on width. So, if you want to upload a correct logo, you have to modify the code in child theme.

So pls think carefully this then let me know your intention
Regards,
