Largest mouth gape (female)

The largest mouth gape (female) is 8.10 cm (3.19 in), and belongs to Susan Morgan (UK) as verified in Durham, UK, on 27 July 2025.

After watching a segment on 'This Morning" about the current record holder placing things in her mouth, Susan thought to herself that she could match that. After always thinking she had a big mouth, but never thought it could be the biggest in the world. After some careful measuring, she is excited to achieve this Guinness World Records title.
