How to plan a 50th birthday party

14 August 2026 · 5 min

A 50th is the one big birthday where the guest of honour is usually also the planner. Nobody else has the list, nobody else knows which two cousins should not sit together, and the person doing all of it is the one everyone will toast at nine o'clock.

So keep it short: five decisions in an order where each narrows the next, and a worked example of what seventy guests do to a room.

Decide the shape of the day before you fix the date

Format first, always. A reception, a seated dinner, and a dinner that turns into a party are three different days, with three different guest lists and three different finishing times.

Most fiftieths land on the third: guests seated from six or seven, speeches through the meal, tables pushed back later for music. It suits an age when the list is at its widest and much of it drives home before midnight. Our post on a reception or an evening party works through what each format asks of a guest.

The date comes second, and it need not be the birthday itself. A 50th usually falls on a weekday, so most families take the nearest Saturday and say so plainly on the invitation. Good Saturdays go early, so settle the shape on a Tuesday evening and start enquiring on the Wednesday.

Seventy guests, one hall, and what that actually looks like

Fifty years produces four circles of people: family, the friends kept since school or since your twenties, work, and the neighbours and school parents you see every week. Write them as households rather than as names, keep a running total in the margin, and a list of only the people who matter lands near seventy.

Seventy is a comfortable number here. The hall seats 30 to 120 guests, so seventy fills the room without crowding it and leaves floor for the part of the evening nobody spends sitting down.

The layout is the real decision. Long tables down the length of the room put everyone into one conversation and let a speech carry from a chair instead of a microphone. Round tables seat the same number on less floor and free a proper stretch of clear wood at one end for dancing. You cannot have both the longest table and the largest dance floor, and that is better known in the week you book than at half past ten on the night. Our post on how much space each guest needs has the figures behind it.

One thing at this size is worth choosing a venue for. Ours is a single hall, so seventy guests means seventy people hearing the same speeches, with no branch of the family seated around a corner.

Settle the food while the guest list is still moving

Food feels like it has to wait for a final number. It does not: everything is priced per person, so the number can move after the menu is agreed.

The set menus (Sølv, Guld, Platin and Diamant) and the custom menus are all per person, so a cousin who says yes in week three is one more cover and not a renegotiation. Any menu can be made fully vegetarian. Children aged 5 to 12 pay half the menu price, worth counting properly at a party with grandchildren in it. Both lines, the hall and the food, sit on the prices page as a figure per head.

Drinks are their own question with three answers: no drinks at all, soft drinks, or bottles you bring yourselves against a small corkage. Know about the last one early: a 50th is the birthday where somebody has been keeping a case back for the occasion.

Our kitchen is inside the building at Højdevej 59, and that is what gives the evening its slack. If the speeches run twenty minutes long, the main course moves twenty minutes later, and settling it takes a walk down a corridor rather than a call to a supplier who left at six. The catering page covers what comes out of it.

The running order that keeps the evening from sagging

At a 50th, everyone wants to speak. That is what most often runs a night into trouble, and one conversation weeks beforehand fixes it.

• Appoint one person to hold the running order, and give it to them in writing.
• Three speeches before dessert is plenty. The rest go after coffee, or onto the card.
• Give the arrival drink a fixed half hour, so latecomers are absorbed, not waited for.
• Treat cake and coffee as the hinge. The moment those plates clear, the room either gets up or goes home.
• Agree the cut-off time for music at the booking, so nobody is negotiating it near midnight.

The gap between the last plate and the first song is where a birthday sags, so fill it on purpose: clear, coffee, one short speech, then music. Our own people turn the room around while that happens, since decoration, sound system, projector, staff and cleaning already sit inside the hall fee. Nobody in your family carries chairs at their own party.

What to tell us when you enquire

Five lines and a date get you a real answer rather than a brochure:

• the date, plus one alternative Saturday
• the total, and whether it is seated or standing
• how many are children aged 5 to 12, and how many are under five
• how many are vegetarian, and any allergy that must be planned for
• when you want to start and when you want to finish

That is enough to draw the layout, brief the kitchen and give you a figure per head. The birthday page carries the rest of the practical detail.

Two things ease the day itself. Parking on site is free, so the cake, the speech notes and forty balloons come out of the boot at the door. And the metro runs around the clock in this part of the city, so guests who want to stay to the end are not watching for a last train.

The quickest way to settle the layout is to stand in the empty room with your list. Book a visit and we will show you seventy chairs in both arrangements, or send us the date and the number and we will suggest one. We are at Højdevej 59, 2300 København S, on +45 21 95 92 92.
