Bad grammar is one of the biggest turn-offs when it comes to online dating, according to new research.

Match.com asked over 5,000 single people in the US what they valued most in dating profiles - with good grammar rated more important than a partner's confidence or their teeth.

People judged their date on their grammar more than their confidence or teeth

Behind personal hygiene - which was seen as most important for 96 per cent of women and 91 per cent of me - 88 per cent of women and 75 per cent of men said they judged a potential partner by their grammar.

84 per cent of women and 69 per cent of men said they would judge a date for low confidence, while 81 per cent of women and 67 per cent of men said they would judge someone for their teeth.

Proofreading company Grammarly has previously found that a man with two spelling mistakes in his online dating profile was 14 per cent less likely to receive a positive response than those who make none.
