How to Set Up a U-Shape Wedding Table Layout

A u-shape wedding table is one run of long tables bent into three sides around an open end, priced in the same running metres as a single straight run.⁴ It seats guests facing in toward the middle, suits most halls from about 40 guests up to around 90, and needs the open end and the two inside corners decided before a single chair goes down.

Three runs, one open end, every seat facing in.

Why couples pick the U over a single run or two rows

Most Australian couples do not leave the seating to chance: 83% run allocated seating at their reception, against 9% who let guests choose and 8% running a stand-up celebration.² A U-shape is what a lot of that 83% land on once a single long run gets too long for the room, because folding it into three sides closes the far end and puts the whole party in view of each other, not strung out down one line. The trade is a bigger footprint in the middle. The room needs to hold a rectangle roughly as wide as one side is long, not just one long, narrow strip.

How to set it up in five steps

1. Count seats from the guest list, not the shape

Start with the guest count, because everything else in this layout is arithmetic on that one number. Australian couples plan for 108 guests and end up with 85, a cut of 23 driven mostly by budget.¹ Work from 85, or from your own confirmed number once the RSVPs are in.

A U-shape is built from rectangle, or trestle, tables, and they seat by length rather than by headcount. An Australian event-hire company's own spec sheet puts a 2.4-metre trestle at 8-10 seats and a 1.8-metre trestle at 6-8, which reads across both sizes at roughly four guests to a running metre - our own arithmetic on their figures, not a published rate.⁴ At 85 guests that is about 21 metres of table edge in total, split across three sides instead of one.¹⁴

Twenty-one metres at 85 guests, and less for a smaller list.

2. Decide the open end before you decide anything else

Every U has one side missing, and that missing side is the first decision, not the last one. Point it at the dance floor and the head table sits inside the U, facing a room that can also see the party. Point it at the room's entry and every guest is seated before they can see the whole shape, which suits a smaller, quieter room better than a grand entrance does.

Whichever wall the open end faces, that wall is now the room's whole personality for the night. Walk the room and pick it before any table gets placed.

The open end decides what every seated guest looks at.

3. Split the total length across three equal sides

Divide the total from step one by three and that is roughly the length of each side. At 85 guests and 21 metres, that is about seven metres a side, seating around 28 guests each.¹⁴ Keep the three sides close to equal. A U with one long side and two short ones reads as a straight run with two afterthoughts bolted on, not as one deliberate shape.

Three equal sides carry the guest list evenly.

4. Give up the two inside corners before you assign guests

A rectangle table is 76 centimetres deep before anyone sits down at it, by the same hire company's own spec sheet, and two of those tables meeting at a right angle leaves no clean seat in the corner itself - the chair has nowhere to push back to.⁴ Plan on losing one seat at each of the two inside corners rather than discovering it on the day, and add a little back to the guest count in step one if you need to land on an exact number.

The corner itself never seats a guest.

5. Draw the three sides, then assign guests to the whole shape

A U-shape is three straight sides, and PlannedBy's free seat planner already has a rectangle table tool built for a straight side: drag it to length and it locks to a banquet shape, adding seats along both long edges as it grows. Lay out one side at a time, matching the lengths from step three, then assign guests once all three are placed and the corners are marked off.

Draw your own layout Open the seat planner and place three rectangle tables to the lengths from step three. No signup, and the seat count updates as you resize each one.

Assign guests to the finished shape, not to a side in isolation. Reassigning a U after the guest list is locked in means moving people across all three sides at once, not just one.

Common questions

How many guests fit around a U-shape table? Roughly four guests to a running metre of table edge once both long sides of each run are seated, minus one seat at each of the two inside corners. Twenty-one metres of total edge, the Australian average for 85 guests, splits into three seven-metre sides carrying about 28 guests each.¹⁴

What goes in the middle of the U? Nothing that needs a chair. The open floor inside a U is usually left for the dance floor, a band, or simply space for staff to serve without crossing behind seated guests all night.

Is a U-shape better than a single long run? Neither is better in every room. A single run is simpler to plan but needs the most uninterrupted length; a U trades that length for a wider footprint and closes the open end so nobody sits at the far end of a table nobody else can see.

Can round tables sit inside a U-shape layout? Yes, and it is a common pairing: a U-shaped table for the wedding party with round guest tables filling the rest of the room. Measure each separately, since the per-metre U maths and the per-table round maths do not convert into each other.

What is the difference between a table plan and a seating chart? Nothing about the object, only the country. Table plan is the term used in Australia, the UK and Ireland; seating chart is the US and Canadian term for the same document.⁵

Do I need a wider room for a U-shape than for a single run? Yes, in the other direction. A single run needs length; a U needs a room wide enough to hold the open end plus both side runs, so measure the room's width before committing to the shape.

Where a U-shape runs into trouble

A shallow, narrow room. The open end needs almost as much width as one side is long, and a room that only has length to offer suits a single run or two parallel rows better.³

A guest list well past 90. Once each side would need to stretch past what one continuous trestle run can hold without a visible join at eye height, round tables tend to use the same floor space more efficiently.

A reception with no wedding party seated together. The whole case for a U is that it puts a group of people facing the room at once - without that group, a round-table layout gives every guest the same view for less planning.

Once the total length from step one is set, the next decision is the open end in step two. Pick a direction, split the length across three sides, and draw it in the seat planner before you assign a single guest.
