Five block numbers across three pages, and no rule to join them
There is no published seating plan for the Principality Stadium in any form this page can read. The stadium's seating plan page names two blocks — U9 and U10, where the fan zone sits — and otherwise says only that your seat, block, aisle and entry gate will be printed on your ticket, with stewards on hand if you cannot find it. The plan itself is an image. No block directory, no tier-by-tier list, no mapping of gates to blocks.
Three more identifiers exist, and none of them comes from a plan. Blocks L12 and L27 are named on an accessibility page as the ambulant accessible seating for WRU-controlled events. Block 426 is named only as the place the quiet room sits opposite. That is five block identifiers in total, gathered from three pages written for three different purposes.
They look like they might follow a rule. An L prefix and a U prefix suggest lower and upper; a 4xx number suggests a leading digit for the level, which is how the Wembley block numbering and the Croke Park section numbering both work. This page does not infer it, and the refusal is deliberate rather than cautious. Five points from three pages, none of them a seating chart, is not evidence of a system — it is a handful of labels that happen to be legible. Any site printing a Principality block map has either seen a document this one could not find or has done the guessing that this paragraph declines.
The pairing is what makes it worth stating. The WRU publish their capacity to the last seat, and then publish the three tier figures that reconcile to it. The same organisation publishes nothing at all about which block you are in. Precision and absence sitting side by side like that is unusual, and it means the gap is a choice rather than an oversight.
Accessible seating is the exception, and it is documented more precisely than most grounds manage for their general admission. Level 3 has 158 wheelchair spaces plus 269 companion seats; Level 4 has 28 plus 28; Level 6 has 28 plus 28. Ambulant accessible seating is in blocks L12 and L27, with extended handrails fitted within them, for events the WRU control — third-party events may differ. Accessible entry is at Gate 1 from the north on Riverwalk, Gate 3 from the east across Westgate Plaza, and Gates 6 and 7 from the south across Millennium Plaza, each with accessible lanes. A quiet room sits opposite block 426.
For what a block directory normally looks like, and so what the WRU are not publishing, see what a block directory normally contains.
No block is named, which is not the same as none existing
No page on either WRU domain names a block, a range or a stand for visiting supporters. That is where the evidence stops, and it is worth being precise about what it does and does not show.
This is not the Murrayfield seating plan finding. There, Scottish Rugby's 107 help-centre articles were enumerated and visiting supporters appeared exactly once, which is a survey and supports a positive claim that no away section exists. Here the search simply did not turn one up, which is a weaker thing. The WRU's own ticket terms point the other way slightly: they warn that anyone entering an area "designated for the use of any group of supporters to which they do not belong" may be ejected, which means designation happens for at least some events even though no page says where.
So this page records it as not found rather than as absent, and names no block. If you are travelling to a fixture here, the allocation comes from your own union or club for that match, and anyone telling you a fixed away block at the Principality is telling you something the WRU have not published.
Four tours and a zip wire, none of them priced
The stadium runs four tour products — the Principality Stadium Tour, Rugby Legend Tours, Match Day Tours and a seasonal Santa Experience — alongside Zip World Cardiff, which zips over the stadium rather than through it. Booking runs through the stadium's own booking site.
Not one of them carries a published price or a duration. Not on the tours page, which lists the products and links to booking, and not on the booking site's landing page, which references a prices section without showing one. So the position is the same as at Wembley and Old Trafford, where the capacity is documented and the tours are not: the products are named, the route is not costed, and the honest answer to what a tour here costs is that you find out inside the booking flow.
With four products and no published prices, start from how stadium tours are usually sold.
£8 at Leckwith, £15 at Sophia Gardens, and none at the ground
There is no dedicated spectator car parking at or immediately near the stadium, which is a consequence of where it is rather than a policy — the ground sits inside Cardiff city centre. The stadium's own advice is that city centre parking exists in quantity and none of it is theirs.
The park and ride is the cheapest published route in. Leckwith, reached from junction 33 of the M4, costs £8.00 pre-booked or £10.00 on the day, cash only. It drops off on Tresillian Way North behind the train station, 1.5 miles out and 10 to 15 minutes from the centre. The site opens at 09:00 with the first bus at 09:00, the last bus leaves the pick-up point at 19:30, and the car park closes at 20:00. Pre-booked customers are asked to bring a printed confirmation.
For parking closer in, Sophia Gardens is £15.00 cash and about half a mile's walk, opening at 08:00. The Civic Centre is £12.00 pre-booked or £15.00 on the day, also cash, from 08:00. Between them that is the fullest set of published parking prices for any ground on this site, which is worth noting given how many clubs publish none.
Blue badge parking is severely limited for the same city-centre reason. At WRU home matches the available spaces are allocated to the WRU Charitable Trust rather than sold; for third-party events they can be booked through the stadium on a first-come, first-served basis.
73,931, and three tiers that add up to it
The Principality Stadium seats 73,931, and the WRU publish the three tiers that make up that number: 35,151 in the upper tier on Level 6, 15,626 in the middle across Levels 4 and 5, and 23,154 in the lower. Add them and you get 73,931 exactly. No other ground written up on this site publishes a split that reconciles to its own total, and it is the reason this page leads with the capacity rather than the plan.
The rest of the structure is published in the same detail: four stands, seven levels, three tiers, 112 private hospitality suites and 34 public bars, over a pitch of 120m by 79m.
The roof changes nothing about any of it, which is worth saying because readers assume it does. The retractable section covers 8,960 m² over an opening of 105m by 80m and takes 20 minutes to close. The WRU publish no different capacity for open or closed, and no concert capacity at all. The roof changes the weather, not the number of seats.
Three other figures circulate on the WRU's own domains, and they are not one disagreement but three different things. The sustainability page gives 74,500, but explicitly as the stadium that was built in 1999 — "a new 74,500 capacity stadium was created from 56,000 tonnes of concrete and steel" — which is history rather than a competing claim. The 2026 Community Shield announcement describes a "capacity of over 74,000" in the present tense, and that one does compete: it is 69 or more above the figure the stadium's own facts page gives, and nothing reconciles them. And a July 2015 article manages both 74,500 and 72,500 as capacities within the same piece, contradicting itself before it contradicts anything else.
This page leads with 73,931 because it is the only one of the four that is published with its own arithmetic attached. A figure you can check against its parts is a different kind of claim from one asserted in passing, and three of these four are asserted in passing.
A figure published with its own arithmetic is rarer than it should be — reading a capacity you can check.
Where it sits, and why the pin is not the WRU's
The WRU publish no coordinate on any page cited here, so the pin below comes from OpenStreetMap — object way/1287329038, classified leisure/stadium. The query returned a single result with nothing to reject, which is the exception on this site rather than the rule: Anfield offered its own suburb, Wembley its own railway station, and both would have looked plausible.

The Principality Stadium's retractable roof takes how long to close?
Show the answer
20 minutes. Closing it changes nothing about capacity: the WRU publish no separate figure for the roof open or shut, and none for concerts.
