Key takeaways

Welterusten is the neutral, safe phrase for any situation, from a colleague to a stranger.
Slaap lekker means "sleep well" and is warmer, more personal, and very common between friends and family.
Welterusten is one word, not two, and it is said when someone is going to bed, not when they are leaving a party.
For a child, Dutch parents often say slaap lekker, droom fijn or trusten as a short, soft version of welterusten.

What is the difference between welterusten and slaap lekker?

Welterusten is the standard, polite good night, while slaap lekker is the friendly, informal "sleep well" you use with people you know.

Welterusten literally comes from wel (well) and rusten (to rest). It is the phrase you will hear in shops, at the office, or from a neighbour when someone is heading home to bed. It works in almost every situation and never sounds strange.

Slaap lekker is more intimate. It means "sleep well" and it is what you say to a partner, a friend, a housemate, or a child at bedtime. You can also say slaap lekker, droom fijn (sleep well, dream nicely) or simply slaap lekker with a soft tone. If you are not sure which one to use, welterusten is always correct, and slaap lekker is always welcome when the relationship is warm.

When do you say welterusten in the Netherlands and Belgium?

You say welterusten when someone is actually going to sleep or going to bed, not when they are leaving a party or a café.

In both the Netherlands and Belgium, welterusten is used at the end of the day, usually at home or when saying goodbye to someone who is going to bed. If a guest is leaving your house at night, you say goedenavond (good evening) or tot morgen (see you tomorrow), not welterusten. If your partner is going upstairs to sleep, welterusten or slaap lekker is perfect.

Timing matters. Dutch speakers do not usually say welterusten as a general goodbye after dinner. It is specifically tied to sleep. So if you are leaving a birthday party at 11 p.m., say tot ziens or goedenavond. If you are the one going to bed while others stay up, say welterusten allemaal (good night everyone) and head upstairs.

Is welterusten one word or two?

Welterusten is written as one word in standard Dutch, and that is the form you should use in writing.

You may see wel terusten in older texts or in very formal writing, but the modern, everyday spelling is welterusten. The same goes for trusten, which is a shortened, affectionate version of welterusten. You will hear trusten mostly from parents to children, or between people who are very close. It is not rude, but it is informal, so avoid it with your boss or a new acquaintance.

What are other Dutch ways to say good night?

Dutch has several warm variations, from slaap lekker to droom fijn, and the one you choose depends on how close you are to the person.

Welterusten: Good night (neutral, safe everywhere).
Slaap lekker: Sleep well (friendly, common with friends and family).
Slaap lekker, droom fijn: Sleep well, dream nicely (warm, often to a partner or child).
Trusten: Night night (short, affectionate, informal).
Tot morgen: See you tomorrow (used when you will meet again the next day, not a direct good night).
Welterusten allemaal: Good night everyone (when leaving a room of people who are staying up).

There is also goedenacht, which is a direct translation of "good night" and is understood, but it is far less common in daily speech. Dutch speakers almost always choose welterusten or slaap lekker instead. If you use goedenacht, it may sound a little stiff or translated, though nobody will misunderstand you.

How do you pronounce welterusten and slaap lekker?

Welterusten is pronounced roughly as vel-tuh-RUS-tun, with the stress on the third syllable and a soft Dutch w that sits between English v and w.

The e in wel is short, like in English "bell". The u in rusten is a Dutch sound that does not exist in English: it is made with rounded lips, a bit like the u in French tu or German müssen. The final en is often reduced to a soft un or even just n in casual speech, so you will hear welterust'n.

Slaap lekker is easier: slaap LEK-ker. The aa is a long, open sound like in English "father", and the e in lekker is short, like in "bed". The r at the end is soft and often barely pronounced in the Netherlands, while in Belgium it is a bit more rolled. Stress the first syllable of lekker.

What should I actually say at bedtime?

If you are going to bed and someone is still up, say welterusten or slaap lekker depending on how close you are. If someone else is going to bed, you say the same thing back.

Here are a few practical phrases you can use tonight:

Welterusten: Good night (neutral, safe).
Slaap lekker: Sleep well (friendly).
Slaap lekker, droom fijn: Sleep well, dream nicely (warm).
Trusten: Night night (short, affectionate).
Ik ga naar bed, welterusten: I am going to bed, good night.
Tot morgen: See you tomorrow (if you will meet again).

One small tip: Dutch speakers often add the person's name or a soft hoor at the end, as in slaap lekker hoor. That hoor does not mean "hear"; it softens the phrase and makes it sound kind. You will hear it constantly in the Netherlands and Belgium.

"I used to freeze at bedtime with my Dutch partner's family. I would just smile and nod. Then I learned welterusten and slaap lekker, and now I say them without thinking. It sounds small, but it made me feel like I actually live here."

Why does this matter for Dutch learners?

Small bedtime phrases are low-pressure practice, and they build the habit of speaking Dutch out loud even when you are tired.

For many learners, the hardest part of Dutch is not grammar but the moment of speaking. Bedtime phrases are short, predictable and repeated every day, which makes them perfect for building confidence. You can practise welterusten and slaap lekker with a partner, a housemate, or even your cat. The point is to get your mouth used to Dutch sounds in a calm, safe moment.
