Ofcourse in answer to your question, I would consider for my girls a possible match with a boy up to 10 years older, and for my sons a girl up to 5 years older.
I would never DELIBERATELY SEEK an older match, but if my child was finding it hard to meet the right person, I would suggest greater flexibility age wise. I am indeed a proud mother !! I want my children to be happy, settled and Torah true, we all do don’t we, for me that means looking at the individual not the package and social expectations.
It is hard to meet the right person and dealing with communal expectations make it even harder.
