40th Birthday Wishes: 26 Messages & Funny Toasts

Updated 2026-07-07

Forty is the birthday people pretend to dread and secretly enjoy — old enough to know better, young enough to do it anyway, and finally past caring what the room thinks. The card can be a roast, a tribute, or both.

Twenty-six options below, from 'prime of your life' to 'vintage, like fine wine, or cheese'.

Short and sweet

What to write for a 40th birthday

Forty's secret theme is confidence — 'zero patience for nonsense, and it took forty years to build' celebrates what the decade actually feels like.

Roast within the friendship: over-the-hill jokes work at 40 only from people with shared mileage. One knee/back joke, then a real tribute.

'The decade the rest were practicing for' reframes forty as an arrival, not a decline — that's the line that gets kept.

Questions

What do you write in a 40th birthday card?

Tribute plus a wink: 'Forty looks good on you — the confidence, the perspective, the zero patience for nonsense.' One over-the-hill joke maximum, and make it affectionate.

Is it okay to joke about turning 40?

From friends with history, yes — the roast IS the affection. From anyone else, lead with 'prime of your life' energy and let them make the age jokes first.
