My cousin asked me last week why her logo looked sharp on her desktop but fuzzy once she opened her site on her phone. It made me think about how often marks are tested on one screen only. A logo design london team would say a logo has to hold up at every size before it is signed off, since phones shrink it fast. A wordpress website design UK team would add that headers, favicons and footers all show the mark at different scales, so one weak version undermines the rest. So I am curious, have you checked how your logo looks on a small screen lately?
