What to write in a wedding card, however well you know the couple

A wedding card does not require grand advice about marriage. Start by congratulating both people, then add warmth at the level your relationship supports. A friendly two-sentence note is better than borrowed intimacy.

When you know one person better

Address both names. You can mention how happy you are for your friend without making their partner an afterthought. If you have not met the partner, “I look forward to getting to know you” is honest; “You two are my favourite couple” may not be.

When you are very close

Choose a memory that makes sense to both people. Keep embarrassing stories for another setting, and avoid references to former relationships. One observed quality—how they welcome people, make each other laugh, or share a project—can be more meaningful than an elaborate prediction.

When the relationship is formal

A colleague or distant relative can offer uncomplicated good wishes. You do not need to imitate a best friend’s tone. Religious wording belongs only when you know it is welcome; neutral language can still be sincere and celebratory.

Turn advice into a wish

Before: “Always compromise and never go to bed angry.”
After: “Wishing you a home where you both feel heard, and plenty of ordinary days you love sharing.”
The revised line offers goodwill without assigning rules to a relationship you do not live inside.

Check the practical details

Use the names and spelling the couple use. Avoid assumptions about surname changes, children or gender roles. Sign clearly, especially if the card accompanies a gift. If you cannot attend, see sending wedding wishes from afar.
